Hi
you can choose any document in GR-IR account and clear it only if you need .. just open F.13
inset the company code and fiscal year and assignment " open GR-IR GL line item display , copy the assignment field for doc. you need to clear''
click on check box select GL and add GR-IR GL account no.
run this process on test mode at the beginning .
and if the result give the same no. of doc. cleared as you count them in GR-IR GL display..
run it by un-checking test mode
