Credits Return Posting Issue
Dear SD Experts,
This is my flow:
Sales Order > Delivery > PGI > Billing (ZF2) > Return Order > Return Delivery > PGR > Credit Return (ZRE)
My issue lies where the posting of the Credit Return is exactly the same as my Billing
By right it should be a negative posting instead of a positive in Credit Return. Bear in mind that my billing document for Credit Return calculation is correct which is showing a negative figure BUT the posting has become a positive. It is posting like a normal invoice using Posting Key '01' & '50' instead of '11' & '40'
Please advise where can i config this to fix this problem?
