When I run the BADI calculations for the model, I observe some dumps in ST22 with exception CX_UJO_W RITE_BACK and terminated program CL_UJO_WRITE_BACK=============CP Error Analysis: The reason for the exception is: Error obtaining concurrency lock (enqueue_server_busy) when I observe the RSPLSE , in the Tab 'Locking Conflict' I find some selections in lock request. Please find attachment. How to release the Locks in the RSPLSE ? there are no entries in SM12. Regards Srinivas
