Integration with PAI Skills
AutomotiveManufacturing
- Work instructions reference SAP transactions
- Document control aligned with SAP DMS
- Quality procedures link to QM inspection
SupplyChain
- Purchasing processes in MM
- Supplier scorecards from QM data
- Inventory management strategies
A3CriticalThinking
- Root cause analysis for SAP process issues
- Priority hierarchy for system changes
Examples
Example 1: Creating a purchase order for raw material
User: "I need to create a PO for 500kg of 6061 aluminum billet from our approved vendor"
Approach: Confirm a source list/info record exists for the material-vendor pair, raise the PR (ME51N) if one isn't already converted, convert to PO (ME21N) with the correct purchasing group and plant, check the release strategy (ME28) if the value exceeds the approval threshold, and confirm the vendor's planned delivery time (PLIFZ) against the need date.
Example 2: Production order stuck in COGI
User: "CO11N confirmation is failing with a backflush error for order 100234"
Approach: Open COGI to see the failed movement, check component stock in MMBE (is it short, or sitting in blocked/QI stock instead of unrestricted), verify the storage location determination on the order, correct or post the missing stock, then reprocess the order from COGI rather than re-confirming from scratch.
Example 3: MRP not generating planned orders
User: "MD04 shows nothing for material X even though stock is below the reorder point"
Approach: Check the planning file entry (MD21) — if the material isn't flagged as relevant it won't be picked up by MD01/MD02. Verify the MRP type is PD (not VB/ND), confirm the lot size procedure isn't suppressing small orders, and check the MRP area assignment matches the plant/storage location in question.
