Question:
How do you delete an idoc that hasn't been successfully processed?
Answer:
We can't delete the IDOC from database but we can mark the IDOC for deletion which changes the status from error 51 or 56 to "68" .
Procedure :
Go to transaction BD87 --> highligh the IDOC you need to mark for deletion and select the option restrict and process --> it navigates you to another prog --> uncheck the import in background --> execute --> Now you can see the button mark the IDOC for deletion
or the programs are RBDMANI2 ( for 51 status to 68 )
and RBDAGAI2 ( for 56 to 68 )
