SC4SAP Create Object

Guided ABAP object creation workflow. Hybrid mode: confirms transport and package interactively, then auto-creates, writes initial code, and activates the object.

sc4sap:create-object handles the full lifecycle of creating a new ABAP object: determining the right object type, confirming package and transport assignment, creating the object via MCP, generating a well-structured initial implementation, and activating it — all in one workflow.

<Response_Prefix> Every response triggered by this skill MUST begin with [Model: <main-model> · Dispatched: <sub-summary>] per ../../common/model-routing-rule.md § Response Prefix Convention. </Response_Prefix>

<Phase_Banner> Multi-phase skill. Before each Agent(...) dispatch, emit ▶ phase=<id> (<label>) · agent=<name> · model=<Opus 4.7|Sonnet 4.6|Haiku 4.5> per ../../common/model-routing-rule.md § Phase Banner Convention. </Phase_Banner>

<Use_When>

• User says "create", "new class", "new program", "create object", "add a function module", "new table", etc.
• A new ABAP development artifact needs to be created from scratch
• User knows what they want to build but needs the creation scaffolded correctly </Use_When>

<Do_Not_Use_When>

• Modifying an existing object -- use direct MCP Update* tools (UpdateClass, UpdateProgram, UpdateInclude, etc.)
• Creating multiple interdependent objects -- use /sc4sap:team for parallel orchestration or /sc4sap:create-program for a full program with includes
• User just wants to understand what type to use -- ask a module consultant agent directly </Do_Not_Use_When>

<Session_Trust_Bootstrap> MANDATORY — runs as Step 0 before any MCP call or user interaction.

Invoke /sc4sap:trust-session with parent_skill=sc4sap:create-object to pre-grant all MCP tool + file-op permissions for this session (eliminates per-tool "Allow this tool?" prompts during Create* + activation flow).

• If .sc4sap/session-trust.log already has a line within the last 24h, skip silently.
• Otherwise run it and surface the one-line confirmation.
• All subsequent Agent dispatches within this skill MUST pass mode: "dontAsk".

Full spec: see ../trust-session/SKILL.md. </Session_Trust_Bootstrap>

</Supported_Object_Types>

<ECC_DDIC_Fallback> MANDATORY: Read ../../common/ecc-ddic-fallback.md before creating any Table / Data Element / Domain. It defines when the ECC branch triggers, the helper-program naming rules, the strict template format (mirroring the files under ecc/), and the hard constraints ($TMP only, no activate, no CTS). </ECC_DDIC_Fallback>

<Field_Typing_Rule> MANDATORY for every Table / Structure / Table Type field-type decision (standard MCP flow and ECC helper-program fallback): read ../../common/field-typing-rule.md.

Priority: Standard DE (1) → existing CBO DE (2) → new CBO DE (3) → Data Type + Length (4, last resort). Raw primitives like LIFNR CHAR 10 / MATNR CHAR 40 / BUKRS CHAR 4 are forbidden when an authoritative SAP data element exists. Before each field, run SearchObject against DTEL and check .sc4sap/cbo/<MODULE>/<PACKAGE>/inventory.json. </Field_Typing_Rule>

<Function_Module_Rule> MANDATORY for every UpdateFunctionModule source emission: read ../../common/function-module-rule.md.

FM signature is stored inline in the FUNCTION statement source (SAP parses it on write and updates TFDIR/FUPARAREF automatically). There is no separate "parameters" endpoint. Every FM source MUST declare IMPORTING / EXPORTING / CHANGING / TABLES / EXCEPTIONS clauses directly between FUNCTION {name} and the first .. Never emit the placeholder " You can use the template 'functionModuleParameter' ... line, never use *"*"Local Interface: blocks as a substitute, never declare shadow locals like lv_iv_xxx TYPE ... to stand in for missing parameters.

Remote-Enabled (RFC) flag is a separate concern — stored in TFDIR.FMODE, not in source. Currently requires manual SE37 Properties update; flag this in the completion report. </Function_Module_Rule>

<Hybrid_Mode> Confirm (interactive):

• Object name (enforce Z/Y prefix, max 30 chars, uppercase)
• Package assignment (search with GetPackage if unsure)
• Transport number (list open transports via ListTransports, or create new)
• Short description

Auto-execute (after confirmation):

• Create object via appropriate MCP Create* tool
• Generate initial implementation (skeleton with proper structure)
• Activate the object
• Verify activation via GetInactiveObjects </Hybrid_Mode>

<Workflow_Steps> MANDATORY: Follow the step sequence defined in workflow-steps.md.

Per-step model allocation (skill main thread runs on Haiku 4.5 per frontmatter; creation + report delegate to agents):

Step	Owner	Model	Role
0 Trust	skill-to-skill	Haiku	permission bootstrap
1 Classify	main	Haiku	keyword → object type
2 Metadata	main	Haiku	name / package / transport / description (Q&A + SearchObject + ListTransports + naming validation)
3 Pre-Creation Check	main	Haiku	SearchObject (name-exists guard)
3.5 Version Branch	main	Haiku	SAP_VERSION ECC vs S/4 routing
4 + 5 + 6 Create + Implement + Activate (standard flow)	sap-executor with model: "opus" override	Opus 4.7	One dispatch covers: CreateClass/CreateProgram/... → UpdateClass/UpdateProgram/... with initial implementation code → ActivateObjects → GetInactiveObjects verify. The Opus override is justified because Step 5 is novel code generation (common/model-routing-rule.md § Tier 2) — field typing priority 1–4, class constructor + method signatures, FM inline parameter declarations, etc.
4-ECC DDIC Helper Program (ECC fallback)	sap-executor with model: "opus" override	Opus 4.7	ECC-only branch for Table/DTEL/DOMA. Executor picks the matching template from skills/create-object/ecc/, substitutes names, fills the field list per common/field-typing-rule.md, and CreateProgram + UpdateProgram + ActivateObjects the helper into $TMP.
7 Completion Report	sap-writer (Haiku base — no override)	Haiku 4.5	Pure formatting from the executor's structured return. Localizes to the user's current conversation language. For ECC fallback, uses the mandatory report format in workflow-steps.md § Step 7 verbatim (do NOT rephrase the ⚠ header + 3-step SE38/SE11 checklist).

At Step 2 (metadata collection) — when the object belongs to a specific SAP module (MM table, SD structure, PS data element, …) — the main thread reads SAP_ACTIVE_MODULES from sap.env / config.json and consults ../../common/active-modules.md. If companion modules are active, proactively suggest integration fields (e.g., creating an MM CBO table in a landscape with PS active → suggest adding PS_POSID / AUFNR). Do NOT add silently — propose to user and let them accept/decline, then pass the confirmed field list through to the executor dispatch. </Workflow_Steps>

<Naming_Convention_Enforcement> MANDATORY: Always read configs/common/naming-conventions.md for the complete, authoritative ABAP naming conventions reference before creating any object.

The reference file covers:

• General rules (prefix, case, character set, length limits)
• Module codes (SD/MM/FI/CO/...) for the Z{MODULE}_... pattern
• Object-specific patterns — Classes (ZCL_/ZIF_/ZCX_), Programs (ZR_), Function Groups/Modules, Data Dictionary (ZT_/ZDE_/ZDO_), UI (Dynpro/GUI Status), OData/RAP (Z_I_/Z_C_/Z_BP_/Z_SB_), Enhancements, IDoc/ALE
• Code-level naming (variables: LV_/LS_/LT_/IV_/EV_/MV_; constants GC_/LC_; types TY_; methods)
• Validation rules (uppercase, Z/Y prefix, character set, max length, non-generic)

Quick validation checklist (applied before every create):

1. Starts with Z or Y (customer namespace)
2. UPPERCASE only, characters in [A-Z0-9_]
3. Within max length (30 chars for most objects)
4. Not generic (ZTEST/ZTEMP/ZDUMMY forbidden)
5. Object-type prefix follows the reference (e.g., ZCL_ for classes, ZIF_ for interfaces)
6. Screen = 4-digit number (e.g., 0100); GUI Status = uppercase identifier (e.g., STATUS_0100) — both require a parent program

If the user-provided name violates any rule, suggest a compliant alternative based on configs/common/naming-conventions.md before proceeding. </Naming_Convention_Enforcement>

<MCP_Tools_Used>

• SearchObject — check for existing objects
• ListTransports — list available transports
• GetPackage — verify package existence
• CreateClass / CreateInterface / CreateProgram / CreateFunctionGroup / CreateFunctionModule / CreateTable / CreateStructure / CreateDataElement / CreateDomain / CreateView / CreateServiceDefinition / CreateServiceBinding / CreateBehaviorDefinition / CreateScreen / CreateGuiStatus
• UpdateClass / UpdateProgram / UpdateScreen / UpdateGuiStatus / etc. — write initial implementation
• GetInactiveObjects — verify activation
• ECC DDIC fallback: only CreateProgram + UpdateProgram (target $TMP). CreateTable / CreateDataElement / CreateDomain must NOT be attempted when SAP_VERSION = ECC. </MCP_Tools_Used>
