Partial Reversal of Posting & Clearing Document.

Hello Sir,

We have posted & cleared some documents using T-Code-F-04.

Suppose we have Rs.20.00 lac Cenvat Credit in GL Code-524789 in 50 Separate Documents. Now, we have transferred said Rs.50.00 lac (50 Documents) using F-04 T-Code in Payable A/c-1310589. Since Posting with Clearing is done in single shot while doing posting with clearing only one document generated (suppose-10000001).

Now, We have come to know that Rs.3.00 lakhs (which was originally against 4 Documents) Cenvat Credit has to be reversed hence,

My question is how i can reverse posted with clearing only related to Rs.3.00 lakhs. Since only one document no. 10000001 was generated in F-04, if i tried FBRA for said document it reverse entire Rs.20.00 lakhs.

Thanks
