# SAP BAPI Integration — 9 Modules, 29 BAPIs > **Prerequisites:** SAP RFC connection, ZROUTER_DISPATCH_FM (or direct BAPI), Python 3.8+. > Full BAPI tables: [reference.md](reference.md) ## When to use - Create/modify materials, orders, FI docs via BAPI - Map CSV/XLS fields to BAPI parameters - Debug BAPIRET2 -- the real error message is never in sy-subrc - Create ZROUTER handler for a new functional module - Replace batch input/BDC with BAPI (ex: MB01 → BAPI_GOODSMVT_CREATE) ## Golden Rule ``` 1. BAPI_<OBJECT>_<ACTION> → call with parameters by VALUE 2. Check BAPIRET2-TYPE → NEVER trust sy-subrc 3. E or A in TYPE? → BAPI_TRANSACTION_ROLLBACK 4. Otherwise → BAPI_TRANSACTION_COMMIT EXPORTING wait = 'X' ``` ## Step by step ### 1. Discover BAPI ```bash python scripts/sap_router.py route --action CREATE_MATERIAL --module MM # → "ZROUTER RFC" # List BAPIs of a module grep -A1 "CREATE_MATERIAL\|CREATE_PO\|CREATE_ORDER\|POST_DOCUMENT" scripts/xls_to_bapi.py ``` ### 2. Convert CSV → BAPI payload ```bash # Generate template python scripts/xls_to_bapi.py template --output tmpl.csv --module MM --action CREATE_MATERIAL # Convert data python scripts/xls_to_bapi.py convert --input data.csv --module MM --action CREATE_MATERIAL # Expected: JSON with BAPI_MATERIAL_SAVEDATA payload ``` ### 3. Call BAPI (ABAP) ```abap DATA: ls_header TYPE bapimathead, ls_ret TYPE bapiret2, lv_matnr TYPE matnr, lt_desc TYPE TABLE OF bapi_makt. ls_header-materia
