Customer Transaction Partial Settlement

Hi All,

I have a question on the customer transaction settlement.

I understand that if the customer Invoice and the settlement payment journal have different financial dimension or posting profile, system will generate 2 additional line in CustTrans with type Settlement(TransType 24).

But I also found scenario with exact same FD and Posting profile, If a payment could not fully settle an invoice (partial settlement), system also generate 2 additional line in CustTrans as settlement type.

Does anyone have an explanation on such behaviour in Ax2012 in term of business understanding? Every finance user we encounter actually asked the same question.

Best Regards,

KerZhi
