Hi Mahmud
Before you read further, please know that i recommend not to use this approach, however if this is to be done regardless of the risks associated with it, you may apply it under close supervison of technical team. Please test it in test system thoroughly.
You can try SE11 for table ACAC_OBJECTS. Navigate to contents and enter the table with your object information.
At left hand side, there will be a checkbox to select the line item and then go to Table Entry and click on Delete (Shift+F2). Thats it.
I just tested it on this table and it worked, however due to time constraints I couldnt run end to end cycle for accruals to check any inconsistencies that may arise because of this. So again. Please test thoroughly before you implement this in Production.
Hope it helps
Regards
Mustafa
