Summary :
When using BAPI to modify plant maintenance or service orders tied to a technical reference object in SAP, the error IM 275 ("Reference object for business operation not allowed") may occur, even though similar alterations are permissible through Transaction IW32. This error arises if business transaction 'Enter maintenance processing jerfata' for the reference object is restricted (e.g., due to a deletion flag or inactivity). To resolve this, implement the program adjustments detailed in the attached correction instructions. Pertinent BAPIs include BAPI_ALM_ORDER_MAINTAIN and related components like USERSTATUS.
