name: sap-skills description: General SAP skills repository reference (secondsky/sap-skills). Use for cross-module SAP capability lookup and reference patterns. trigger: keywords: [sap skills, capability lookup, which module, which tcode, which bapi, cross-module, module map, sap reference, business capability] intent: Finding which SAP module, transaction, or BAPI covers a business capability and routing the question to the right module map, router action, or consultant agent prerequisites:

• SAP_ROUTER_ROOT points to the sap-router-skill repository
• Repo module maps present in $SAP_ROUTER_ROOT/references/module_maps/ (15 files, MM through BW)
• $SAP_ROUTER_ROOT/references/data/ populated (sap-notes.yaml, symptom-index.yaml, tcodes.yaml)
• Python available for $SAP_ROUTER_ROOT/scripts/rag_ingest.py, sap_router.py, and fallback_engine.py

SAP Skills — Cross-Module Capability Lookup

Answers "which module / tcode / BAPI does X?" using local reference data, the routing engine, and module consultant agents. Lookup flow: RAG search → module map → router map → consultant agent.

Runtime root

Before running any relative command below, resolve SAP_ROUTER_ROOT, verify that scripts/source_catalog.py exists there, and change the working directory to that repository. Fail closed with a clear configuration error if the variable is missing; do not assume the user's current project contains the router scripts.

1. RAG Search (first stop)

TF-IDF index built from references/data/ (SAP notes, symptom index, tcodes YAML) plus references/module_maps/.

# Build/rebuild the local index (run once, or after editing references/)
python scripts/rag_ingest.py ingest

# Search for a capability, symptom, note, or tcode
python scripts/rag_ingest.py search --query "goods receipt purchase order" --top 3
python scripts/rag_ingest.py search --query "credit memo billing" --top 5

2. Module Maps (curated per-module reference)

15 files in references/module_maps/ — open the one matching the domain:

File	Module
mm_operations.md	Materials Management
sd_operations.md	Sales & Distribution
fi_operations.md	Financial Accounting
co_operations.md	Controlling
pp_operations.md	Production Planning
qm_operations.md	Quality Management
pm_operations.md	Plant Maintenance
wm_operations.md / ewm_operations.md	Warehouse Mgmt / Extended WM
tm_operations.md	Transportation Management
tr_operations.md	Treasury
hcm_onprem_operations.md / hcm_sf_operations.md	HCM on-prem / SuccessFactors
bw_operations.md	Business Warehouse
basis_operations.md	Basis / system administration

3. Router Map (action → execution path)

Once the capability maps to an action ID, ask the router how it executes:

# Route an action through ADT-first / GUI-fallback decision tree
python scripts/sap_router.py route --action MM_CREATE_MATERIAL
python scripts/sap_router.py route --action SD_CREATE_ORDER --functional

# Show GUI tcode / BDC / BAPI alternatives for an action
python scripts/fallback_engine.py map --action MM_CREATE_MATERIAL

# Execute the full 6-tier fallback chain (ADT→RFC→GUI→BDC→Offline→Manual)
python scripts/fallback_engine.py execute --action FI_POST_DOCUMENT --module FI

4. Core Module → Tcode → BAPI Quick Table

Module	Core Tcodes	Core BAPIs
MM	MM01, ME21N, MIGO	BAPI_MATERIAL_SAVEDATA, BAPI_PO_CREATE1, BAPI_GOODSMVT_CREATE
SD	VA01, VL01N, VF01	BAPI_SALESORDER_CREATEFROMDAT2, BAPI_OUTB_DELIVERY_CREATE_SLS, BAPI_BILLINGDOC_CREATEMULTIPLE
FI	FB01, FB03, F110	BAPI_ACC_DOCUMENT_POST, BAPI_ACC_DOCUMENT_REV_POST, BAPI_GL_GETACCOUNTSALDO
CO	KS01, KO01, KB21N	BAPI_COSTCENTER_CREATEMULTIPLE, BAPI_INTERNALORDER_CREATE
PP	CO01, MD02, CS01	BAPI_PRODORD_CREATE, BAPI_MATERIAL_BOM_GROUP_CREATE
QM	QA01, QM01, QA32	BAPI_INSPLOT_CREATE, BAPI_QUALNOT_CREATE
PM	IW31, IW21, IE01	BAPI_ALM_ORDER_MAINTAIN, BAPI_EQUI_CREATE
HCM	PA30, PA20, PT60	BAPI_EMPLOYEE_GETDATA, HR_INFOTYPE_OPERATION
EWM/WM	/SCWM/MON, LT01	BAPI_WHSE_TO_CREATE_STOCK (WM) / EWM via /SCWM APIs
TR	FF7A, FI12, F110	BAPI_ACC_DOCUMENT_POST (bank postings), DMEE for formats
BW	RSA1, RSPC, RSRT	BAPI_IPAK_START, RSPC_API_CHAIN_START

5. Delegate to Consultant Agents

When the lookup needs domain judgment, spawn the matching agent via the Agent tool:

• Module-specific: sap-mm-consultant, sap-sd-consultant, sap-fi-consultant, sap-co-consultant, sap-pp-consultant, sap-qm-consultant, sap-pm-consultant, sap-hcm-consultant, sap-ewm-consultant, sap-tm-consultant, sap-tr-consultant, sap-bw-consultant
• General / unclear module: sap-tutor (classifier) — it redirects to the right specialist and answers cross-module architecture questions

Rule: route general "how does SAP handle X" questions to sap-tutor; route "configure/troubleshoot X in module Y" to the module consultant.

Pitfalls

• RAG search returns nothing → Cause: index never built or references/ edited since last build. Solution: run python scripts/rag_ingest.py ingest, then retry the search.
• Action ID unknown to router → Cause: capability phrased as free text, not a mapped action (36 actions mapped). Solution: run python scripts/fallback_engine.py map --action <GUESS> to see the map, or check the module map file for the canonical action name.
• Wrong module guess for a capability → Cause: overlapping terms (e.g., "invoice" exists in MM, SD, and FI). Solution: disambiguate by document direction — inbound/vendor = MM/FI-AP (MIRO/FB60), outbound/customer = SD/FI-AR (VF01/FB70) — then confirm in the module map.
• BAPI exists but fails in cloud/S4 → Cause: classic BAPI not released for ABAP Cloud. Solution: check released APIs first (see abap-cloud skill); fall back to OData/RAP equivalents.
• --module passed to sap_router.py route → Cause: route subcommand has no --module flag. Solution: module context goes to fallback_engine.py execute --module <X>; the router infers module from the action prefix (MM_, SD_, FI_...).

Verification

# Index built and searchable
python scripts/rag_ingest.py search --query "material master" --top 3
# Expect: hits from mm_operations.md and/or tcodes.yaml

# Router resolves a known action
python scripts/sap_router.py route --action MM_CREATE_MATERIAL
# Expect: route decision (arc-1 ADT primary or GUI fallback)

# Fallback map lists tcode/BDC/BAPI alternatives
python scripts/fallback_engine.py map --action MM_CREATE_MATERIAL
