Reversal through FNM3 - wrong debit / credit posting keys

[Former Member]

Hi,

I am not a functional resource but want to post a discussion on "reversal through FNM3" in this forum so my question can be basic for few of you.

Here is my problem ..

I am posting a ordinary loan installment through FNM3 using a existing contract number and I see a document with type XA is created which I can view through FB03 .

Now I use FNM3 to reverse the document and a reversal document is created with the same document type XA correctly but the problem is the reverse document has the same debit/credit code as on the document it should reverse which I think is wrong as I believe the reverse document should have opposite debit / credit set by using posting key 40 debit or 50 credit .

I looked at t-code FNZA to verify account determination posting specifications  for document type 'XA' but strangely I do not see this document type there so was wondering how it is configured.

Can you let me know where I shall look to fix this error ?

Is Document Type 'XA'  a standard one ?

Hi All,

I mark this discussion as answered because I have figured out that a custom BADI is used and some customized checks are written in this BADI which are changing the DEBIT / CREDIT posting keys based on entries in a Z table maintained. I will go back to the business to maintain the Z table which shall resolve this issue.

Thanks for looking into the discussion.
