[Authorization](capability:authorization) runs as the calling user rather than a technical RFC user, a choice forced by a customer security team after an earlier version used a technical RFC user, and a later security review found a display-authority check applied uniformly across every write endpoint. The failure modes that cost the most time sat in [RFC connectivity](capability:rfc-connectivity) itself: RFC_READ_TABLE's empty-table exception collapsed into a false success, a where-used filter was applied only after the row limit, and BAPI calls treated an empty string and an absent parameter as different, silently wrong inputs.","short":"Lessons from an in-system ABAP MCP server for SAP ECC 6.0","author":"NicolasHernandez","published":"2026-08-28","provenance":{"discovered_via":[{"source":"source:sap-community","channel":"abap-development-tag"}],"first_seen":"2026-10-14"},"drafted_with_ai":true,"history":[{"date":"2026-10-17","field":"explains","from":null,"to":"applies_to on capability:mcp-servers (abap); capability:rfc-connectivity (abap); capability:authorization (abap)","reason":"Door scope proposed from the title and summary, so a door page lists the piece only where it holds (docs/concepts/content-on-doors.md)."}]},"readings":{"liveness":[{"label":"Checked against the source","tier":"unknown","evidence":"nobody has checked it"},{"label":"Source reachable","tier":"unknown","evidence":"not crawled"},{"label":"Age","tier":"good","evidence":"published 2 months ago"}],"compatibility":[{"label":"Version","tier":"unknown","evidence":"no version declared"},{"label":"Moved since?","tier":"good","evidence":"no recorded change after 2026-08-28"},{"label":"Findings","tier":"good","evidence":"none flagged"}],"reach":[{"value":1588,"unit":"views"},{"value":0,"unit":"comments"},{"value":3,"unit":"likes"}]},"signals":{"views":1588,"likes":3,"comments":0,"metrics_at":"2026-10-25"},"series":null,"edges":{"authors":[]}}
