Returns Excise FI entry is wrong

Hi All,

Issue : Kindly help to understand why Returns Excise entry is wrong?

Other details:I have created sales invoice and excise invoice for 40 qty and created returns invoice and Return excise invoice with J1is t code for qty of 20:

1. VA01->VL01n->VF01->J1IIN

2. VA01( returns order with ref Invoice)->VL01N/2n ( PGR)-> VF01(credit for returns)->J1IS Returns for Excise using other adjustments( OTHR).

If you observe the below posting key of 221154 in below 4 transactions :

If you observe the 2^nd and 4^th screen shots, the 4^th entry should be reverse to 2^nd screen shot entry but here both are same which is not correct. As per me I feel the Posting key is making this difference if you we can correct this instead of Debit it will Credit this would be fine i think

GL accounts numbers are same need NOT to change  GL number the only change the same GL account in 4^th screen shot should be reverse.

Please let me know what action i should take to correct the 4th screen shot  entry( return excise)?
