Installment source item is changed while doing the Return lot Posting

[pankaj_sap]

Hi Experts ,

We have a requirement to Change the Payment method for the Line item while doing any Return lot Posting(FP09) .So that we have enhanced the FQEVENT 292 to change the payment method in the line item and also configured the Lock(Payment/Dunning) for some of the Return Reason code . It is working perfectly for any item except installment line item.While doing the Return posting for any Installment line item(say 1st installment out of 4 installment) ,Lock is applied and payment method has been changed for that line item which is correct  but it is also changed the Source line item of that Installment Plan  which is not supposed to do this .not sure why SAP is taking the Source line item ? Could you please advice me what need to do for this ?

Thanks ,

Hi Pankaj,

You can use BAPI ' BAPI_INSTMNTPLN_CHANGE '  to change the Installment Plan item.
