S/4HANA Import Assistant

Overview

This skill provides comprehensive guidance for successfully importing data from SAP S/4HANA and BW/4HANA systems into SAP Datasphere. It covers the entire workflow from understanding available source objects to configuring extraction methods and monitoring data flows.

When to Use This Skill

• Initial S/4HANA connection: Setting up Cloud Connector and DP Agent
• Exploring available objects: Finding the right CDS views, InfoProviders, or tables
• Selecting semantically rich data: Choosing extraction-enabled views over raw tables
• Configuring delta extraction: Setting up ODP for real-time or near-real-time data
• Handling BW/4HANA objects: Importing InfoProviders and CompositeProviders
• Troubleshooting connectivity: Resolving Cloud Connector or DP Agent issues
• Managing delta queues: Monitoring and recovering from extraction issues
• Optimizing extraction performance: Choosing the right extraction methods

The Import Entities Wizard Workflow

The Import Entities wizard guides you through a structured process for bringing SAP source objects into Datasphere:

Step 1: Create or Select a Connection

Datasphere UI → Data Integrations → Connections
→ Create New or Select Existing S/4HANA Connection

Required Information:

• Connection Name (e.g., "SAP_S4H_PROD")
• Source System Type (S/4HANA, BW/4HANA, ECC, etc.)
• Host and Port
• Client Number
• Authentication Method (Basic, Certificate, OAuth)
• Cloud Connector Location ID (for on-premise systems)

Example Connection Configuration:

• Source: SAP S/4HANA 2023
• Host: s4h-prod.example.com
• Port: 443
• Client: 100
• Cloud Connector: CC_PROD_001

Step 2: Create a New Replication or Data Integration Task

Data Integrations → New Task
→ Select Source System (from connections)
→ Choose Task Type (Replication Flow, Data Flow, or Transformation Flow)

Step 3: Search and Select Source Objects

The system searches for available objects in the SAP source system:

Search Criteria:

• Object Type (CDS View, InfoProvider, ODP Extractor, Query)
• Business Area (Financial, Sales, Procurement, HR, Supply Chain)
• Object Name or Pattern
• Extraction Method (ODP, Database, Query)

Search Example:

Search: "C_*"
Filter by: CDS Views, Extraction-enabled only
Results: C_CUSTOMER, C_SALES_ORDER, C_INVOICE, ...

Step 4: Configure Extraction Method

Choose how data will be extracted:

Object: C_CUSTOMER (CDS View)
Available Extraction Methods:
  ✓ ODP (Operational Data Provisioning) - Real-time, Delta support
  ✓ Database Access - Direct SQL, Full only
  ✓ API - If exposed as API
  → Select ODP for Delta capability

Step 5: Map Source to Target

Source CDS View: C_CUSTOMER
Fields: CUSTOMER_ID, CUSTOMER_NAME, EMAIL, PHONE, CREATED_DATE
↓
Target Table (auto-created or manual selection)
CUSTOMER_MASTER (new table in Datasphere)

Step 6: Configure Load Settings

Initial Load:
  - Full Load: Yes, load all historical data
  - Parallel Threads: 4 (for performance)
  - Package Size: 10000 rows

Delta Load:
  - Delta Enabled: Yes
  - Delta Type: ODP Change Data Capture
  - Extraction Frequency: Every 15 minutes
  - Watermark Field: CHANGENUMBER (from ODP)

Step 7: Review and Activate

Review:
  - Source: C_CUSTOMER (S/4HANA)
  - Target: CUSTOMER_MASTER (Datasphere)
  - Method: ODP with Delta
  - Schedule: Automatic every 15 minutes

Status: Ready to Activate

Identifying Extraction-Enabled CDS Views in S/4HANA

Not all CDS views are extraction-enabled. You must use views explicitly marked for extraction:

Characteristics of Extraction-Enabled CDS Views

Naming Convention:

• Prefix C_ : Consumer views, extraction-enabled (e.g., C_CUSTOMER, C_SALES_ORDER)
• Prefix I_ : Internal views, not for extraction
• Prefix P_ : Projection views
• Prefix DD_ : Domain-specific views

Extraction Capability Indicators:

1. @Analytics Annotation

@Analytics.dataCategory: #FACT
@Analytics.dataExtraction.enabled: true
define view C_SALES_ORDER as
  select from vbak {
    vbak.vbeln as SalesOrderNumber,
    vbak.erdat as CreatedDate,
    vbak.netwr as NetAmount
  }

2. @Semantics Annotation

@Semantics.amount.currencyCode: 'CurrencyCode'
@ObjectModel.Composition.RefreshingElement: true

Finding CDS Views in S/4HANA

Via Transaction SE11 (ABAP Dictionary):

SE11 → CDS View → Search for C_*
Filter: "Author = SAP" AND "Extraction Enabled = X"

Via Search in Datasphere:

Data Integrations → Search Catalog
Source: S/4HANA_PROD
Type: CDS View
Search Text: "customer" OR "sales" OR "invoice"

Common Extraction-Enabled Views by Module:

Module	View Name	Purpose
Finance	C_GENERALLEDGER	General Ledger transactions
Finance	C_CUSTOMER_INVOICE	Customer invoices
Finance	C_SUPPLIER_INVOICE	Supplier invoices
Sales	C_CUSTOMER	Customer master
Sales	C_SALES_ORDER	Sales orders
Sales	C_SALES_ORDER_ITEM	Sales order line items
Procurement	C_SUPPLIER	Supplier master
Procurement	C_PURCHASE_ORDER	Purchase orders
Procurement	C_PURCHASE_ORDER_ITEM	Purchase order lines
Inventory	C_MATERIAL	Material master
Inventory	C_MATERIAL_STOCK	Inventory balances
HR	C_EMPLOYEE	Employee master
HR	C_EMPLOYEE_SALARY	Salary information

Verify Extraction Capability

Use the search_catalog MCP tool:

search_catalog(
    source="S/4HANA_PROD",
    object_type="CDS_VIEW",
    search_term="C_CUSTOMER",
    extraction_enabled=True
)

Expected output includes extraction metadata:

{
    "object_name": "C_CUSTOMER",
    "extraction_enabled": true,
    "extraction_types": ["ODP", "DATABASE"],
    "delta_capable": true,
    "fields": [
        {
            "name": "CUSTOMER_ID",
            "type": "STRING",
            "key": true,
            "changeable": false
        },
        {
            "name": "CUSTOMER_NAME",
            "type": "STRING",
            "changeable": true
        }
    ]
}

Understanding CDS View Annotations

Annotations in CDS views control behavior and extraction characteristics:

@Analytics Annotations

@Analytics.dataCategory: #FACT              -- Type: FACT, DIMENSION, CUBE, QUERY
@Analytics.dataExtraction.enabled: true     -- Enable extraction
@Analytics.dataExtraction.deltaSupported: true  -- Support delta extractions

@ObjectModel Annotations

@ObjectModel.readOnly: true                 -- View is read-only
@ObjectModel.transactional: false           -- Not transactional
@ObjectModel.usageType: #FACT                -- Usage classification
@ObjectModel.Composition.RefreshingElement: true  -- Refresh semantics

@Semantics Annotations

@Semantics.amount.currencyCode: 'CurrencyCode'    -- Currency field
@Semantics.quantity.unitOfMeasure: 'UnitOfMeasure' -- UOM field
@Semantics.calendar.date: true              -- Date field
@Semantics.businessKey: true                -- Business key

@EndUserText Annotations

@EndUserText.label: 'Customer Master'
@EndUserText.description: 'Extraction-enabled customer master data'
@EndUserText.quickInfo: 'All customers from KNVP and KNVV tables'

ODP (Operational Data Provisioning) Extractors

ODP is SAP's modern extraction framework, replacing older RFC-based methods:

ODP Architecture

S/4HANA System
├── ODP Provider (e.g., CDS View C_CUSTOMER)
├── ODP Context (e.g., ABAP:CDS_VIEWS)
├── Change Log Table
├── Delta Queue (Pending changes)
└── Watermark (Last extracted position)

ODP Extractor Types

Type	Source	Use Case	Delta Support
CDS_VIEWS	Extraction-enabled CDS views	Modern standard objects	Yes (FULL)
FUNCTION	RFC function modules	Custom extraction logic	Yes
TABLE	Database tables	Direct table access	Yes
QUERY	ABAP query/report	Parameterized extraction	No
LOGICAL_LOG	Application log/changes	Event-based changes	Yes

Configuring ODP Delta Load

Source: C_SALES_ORDER (ODP Provider)
Delta Configuration:
  - Delta Type: FULL_THEN_DELTA
  - Semantics: Changed records only
  - Key Fields: SALES_ORDER_NUMBER (determines uniqueness)
  - Extraction Sequence: Change Number (internal counter)

Example Delta First Run:
1. Full load: all records
2. Store watermark: CHANGENUMBER = 1000000

Example Delta Second Run:
1. Query: CHANGENUMBER > 1000000
2. Delta load: only changed since last run
3. Update watermark: CHANGENUMBER = 1000050

ODP Change Data Capture (CDC)

ODP tracks changes via change numbers and delta queues:

Change Number = Internal sequence counter
When a record changes:
  → ODP logs the change
  → Increments change number
  → Stores in delta queue
  → Available until queue is cleared (usually 3-8 days)

Delta Extraction Sequence:
  Initial Load (FULL): Get CHANGENUMBER = 500000
  Delta Load (Day 2): WHERE CHANGENUMBER > 500000
  Delta Load (Day 3): WHERE CHANGENUMBER > 500050
  ...

ABAP CDS Views: Released APIs vs Custom Views

SAP-Released CDS Views (Safe for Production)

Characteristics:

• Prefix: C_ (consumption) or published by SAP
• Fully documented and supported by SAP
• Extraction-enabled with stable field lists
• Backward compatible across releases
• Published in SAP API Hub

Example - C_GENERALLEDGER:

@VDM.viewType: #CONSUMPTION
@ObjectModel.semanticKey: ['CompanyCode', 'DocumentNumber', 'FiscalYear']
@Analytics.dataCategory: #FACT
@Analytics.dataExtraction.enabled: true
define view C_GENERALLEDGER as
  select from fin_gl_posting as posting {
    posting.bukrs as CompanyCode,
    posting.belnr as DocumentNumber,
    posting.gjahr as FiscalYear,
    posting.dmbtr as Amount,
    posting.budat as DocumentDate
  }
  where posting.bukrs <> ''
    and posting.dmbtr <> 0;

Custom CDS Views (Use with Caution)

Risks:

• No support guarantee from SAP
• Fields may change or disappear
• Not backward compatible
• May not have extraction enabled
• Performance not optimized for extraction

When to use custom views:

• SAP standard view doesn't exist
• Need to combine multiple tables
• Apply complex filtering/calculations
• Specific business requirements

Creating a custom extraction-enabled view:

@VDM.viewType: #CONSUMPTION
@Analytics.dataCategory: #FACT
@Analytics.dataExtraction.enabled: true
@Analytics.dataExtraction.deltaSupported: true
@EndUserText.label: 'Custom Sales Analysis'
define view Z_CUSTOM_SALES as
  select from vbak as orders
    inner join vbap as items on vbak.vbeln = vbap.vbeln
    left outer join vbrk as invoices on vbak.vbeln = vbrk.xblnr {
      vbak.vbeln as SalesOrder,
      vbap.posnr as LineNumber,
      vbak.erdat as CreatedDate,
      vbap.netwr as NetAmount
    };

BW/4HANA Objects: InfoProviders and CompositeProviders

BW/4HANA uses InfoProviders as the primary data container for analytics:

InfoProvider Types

Standard InfoProvider (Cube):

BW/4HANA → InfoProvider: /BIC/SALES (Facts and dimensions)
├── Fact Table: /BIC/FSALES00
├── Dimensions:
│   ├── 0CUSTOMER (Customer dimension)
│   ├── 0MATERIAL (Material dimension)
│   └── 0PLANT (Plant dimension)
└── Measures: Sales Value, Quantity, Margin

CompositeProvider (Virtual Cube):

CompositeProvider: /BIC/COMP_SALES
├── InfoProvider 1: /BIC/SALES (Current year)
├── InfoProvider 2: /BIC/SALES_ARCHIVE (Prior years)
└── Query logic: UNION with transformation rules

Extraction from BW/4HANA

Via ODP:

BW System → ODP Provider (BW:INFOPROVIDER)
Source: /BIC/SALES
Type: InfoProvider
Delta: Change request number (BW concept)
Extraction: All cubes support ODP extraction

Configuration:

Source BW Object: /BIC/SALES
Characteristics (Dimensions):
  - 0CUSTOMER
  - 0MATERIAL
  - 0PLANT

Key Figures (Measures):
  - 0SALES_VALUE
  - 0QUANTITY
  - 0GROSS_MARGIN

Load Setting:
  - Initial Load: Full (all data)
  - Delta: Request-based (BW change request tracking)

BW Query Extraction

Query Option (Extract from OLAP Query):

BW Query: Z_SALES_ANALYSIS
└── Extract directly as data source
├── Advantages: Complex logic defined in query, pre-calculated
├── Disadvantages: Delta not supported, slower than ODP
└── Use case: Aggregated reporting data

Connection Prerequisites

Cloud Connector Setup (On-Premise Systems)

The Cloud Connector acts as a reverse proxy tunnel between cloud and on-premise SAP systems:

Installation Checklist:

1. Procurement

   • Download Cloud Connector from SAP downloads
   • Obtain license key
   • Allocate VM or physical server (4GB RAM minimum)

2. Installation

   • Install on machine in SAP network
   • Configure JDK (Java 11+)
   • Set up HTTPS certificates
   • Configure administrative user

3. Configuration

   Administration UI: https://localhost:8443
   Add Backend System:
     - System Type: SAP System
     - Host: s4h-prod.example.com
     - Port: 443
     - Protocol: HTTPS
     - Virtual Host: s4h-prod (for cloud access)
   
   Resource Mapping:
     - URL Pattern: /sap/opu/odata/sap/*
     - URL Regex: ^/sap/opu/odata/sap/.*
     - Check: YES (enabled)
   

4. Certificate Exchange

   • Export Cloud Connector certificate
   • Import in S/4HANA trusted store
   • Exchange client certificate if using mutual TLS

5. Testing

   • Test from Datasphere → Cloud Connector → SAP system
   • Verify ODP availability
   • Check latency and throughput

Cloud Connector Architecture:

Datasphere (Cloud)
    ↓ HTTPS
Cloud Connector (DMZ/Internal Network)
    ↓ HTTPS/HTTP
S/4HANA System (On-Premise)

DP Agent Setup (Alternative to Cloud Connector)

Data Provisioning Agent is used in some scenarios:

When to use DP Agent:

• Multi-tier network (requires agent in SAP network)
• Firewall restrictions prevent Cloud Connector
• Batch/scheduled extractions preferred

Installation:

Download: SAP Datasphere → Administration → DP Agent Download
Install on: Server in SAP network with access to source systems
Configure:
  - Datasphere tenant URL
  - OAuth credentials or certificate
  - Source system connections

Start Agent: .\dpsagent.exe start
Verify: Check "Agent Status" in Datasphere Administration

DP Agent Communication:

Datasphere → HTTPS → DP Agent (On-Premise)
           ← Data ← Source Systems

Delta Extraction Patterns

Pattern 1: Timestamp-Based Delta (Most Common)

Setup:

Source View: C_CUSTOMER
Delta Field: CHANGED_AT (timestamp)
ODP Configuration:
  - Track changes via timestamp
  - Load only records changed since last run

Extraction Sequence:

Day 1: Full load all customers (CHANGED_AT <= 2024-01-15)
       Save watermark: 2024-01-15 23:59:59

Day 2: Delta load where CHANGED_AT > 2024-01-15 23:59:59
       Changes: 150 new/updated records
       New watermark: 2024-01-16 23:59:59

Day 3: Delta load where CHANGED_AT > 2024-01-16 23:59:59
       Changes: 75 new/updated records

Advantages: Simple, reliable, handles late arrivals Disadvantages: Requires timestamp maintenance

Pattern 2: Change Number Sequence (ODP Native)

Setup:

Source: C_SALES_ORDER
ODP provides: Change Number (CHANGENUMBER field)
Automatic tracking by ODP

Extraction Sequence:

Day 1: Full load with CHANGENUMBER up to 5000000
Day 2: Delta where CHANGENUMBER > 5000000
       Extract: records 5000001 to 5000500
Day 3: Delta where CHANGENUMBER > 5000500

Advantages: ODP handles completely, most reliable Disadvantages: Limited history (3-8 days typically)

Pattern 3: Logical Change Document (For Complex Changes)

Setup:

Source: BW InfoProvider
Tracking: Change request numbers
Each request = batch of changes

Handling:

Request 001: 1000 rows inserted
Request 002: 500 rows updated
Request 003: 100 rows deleted

Delta load pulls complete requests (no partial)

Best Practices for S/4HANA Imports

1. Choose the Right Extraction Method

Decision Tree:

Need Real-time Data?
├─ YES → Use ODP if available
│        └─ Delta every 5-15 minutes
└─ NO → Can batch load suffice?
         ├─ YES → Use Database access or ODP batch
         └─ NO → Use ODP with frequent schedule

2. Identify Semantically Rich Objects

Semantic Richness Hierarchy:

1. SAP-provided consumption CDS view (C_*) ✓✓✓ (Use this)
2. SAP cluster/pooled table via CDS ✓✓
3. SAP standard table via CDS ✓
4. Custom CDS view ✓ (Use with caution)
5. Raw SAP table ✗ (Avoid if possible)

Why it matters:

• Consumption views have business logic applied
• Transformations and hierarchies built-in
• Data quality rules enforced
• Fields well-documented and stable

3. Handle Hierarchies Correctly

Hierarchy Example (0CUSTOMER dimension):

Hierarchy Structure:
Region
├── North America
│   ├── USA
│   │   ├── East Region
│   │   └── West Region
│   └── Canada
└── Europe
    ├── UK
    └── Germany

Extract with Hierarchy:
- Get all leaf customers
- Include parent relationships
- Track parent changes (SCD Type 2)

Configuration:

BW InfoProvider: /BIC/SALES
Dimension: 0CUSTOMER
Include: Hierarchy levels
  - CUSTHIER01 (Standard customer hierarchy)
  - With parent-child relationships

4. Manage Load Volumes

Large Initial Loads:

Source: C_GENERALLEDGER (500M rows)
Strategy:
  - Partition by date range
  - Load in parallel batches
  - Monitor memory and storage
  - Estimate: 500M rows ≈ 100GB compressed

Configuration:

Parallel Threads: 4-8 (for initial load)
Package Size: 100,000 rows per package
Estimated Duration: 8-12 hours
Monitor: Memory, CPU, Network

5. Monitor Delta Queue Health

Check Delta Queue Status:

Use MCP tool: test_connection(source="S/4HANA_PROD")
Verify:
  - Delta queue not overflowing
  - Change documents available
  - No extraction errors

Delta Queue Limits:

Typical retention: 3-8 days
Size limit: 2-4GB per table
If exceeded: Must do full reload

Monitor:
  - Days of changes retained
  - % of queue capacity used
  - Time since last cleanup
