excise rg23c reversal

hi gurus

very urgent

some j1iex transactions posted to RG23C rigisters instead of RG23A rigisters, actuall postings belongs to INPUT but the postings done for Capital please advise me how to reverse this with out cancelling j1iex.

if the vice versa i can use J1ih other adjustemnt tab for reversal and aditional excise duty tab for actual posting. but above case it was not working because the 50% amount is gone to cenvat on hold account . how to post reversal entry and actual entry please advise

Thanks

Ashwini
