Create an Applied CM via Auto Invoice

Hi Gurus,

As per standard process for CM  creation through Auto Invoice- we need to populate  REFERENCE_LINE_ID with CUSTOMER_TRX_LINE_ID of the transaction being credited.

I have a scenario where for a Mixed Order type - Invoice & CM information is interfaced to AR in same run. How can we create an applied credit memo in this case?

Thanks in advance,

Aashima
