OData $metadata

OData metadata failed to load

Client, Fiori app or API tooling cannot load the service $metadata document.

Likely root causes

  1. Service registration or system alias is broken.
  2. Backend model provider raises an exception.
  3. Authorization, connectivity or metadata-cache inconsistency prevents metadata generation.

What to inspect

  1. Open the service $metadata URL directly.
  2. /IWFND/ERROR_LOG and backend ST22 for the same timestamp.
  3. /IWFND/MAINT_SERVICE system alias and service status.
  4. Gateway metadata cache only after root cause is understood.

Resolution path

  1. Fix registration, alias, backend exception or authorization first.
  2. Invalidate/refresh metadata cache only when a stale-cache condition is actually suspected.
  3. Verify $metadata returns valid XML before retesting the app.
  4. Check that client and backend service versions match.
