Running unload/reload and receive 0874 in IDMSDBL4 step.
Release: All supported releases.
This error occurs when IDMSDBL4 needs to load a database procedure that is called for one of the records being loaded, but can't load that procedure.
Check the records in the area(s) to see if any use a database procedure. Run IDMSRPTS with the RECDES and SETDES parameters against the schema.
The STEPLIB for all RELOAD steps including IDMSDBL4 must contain any database procedures called by the records affected by the RELOAD.
