Where should i set AR transaction source for creation of Credit memos from Advanced collections

Hi Gurus,

I am working on a project "Creation of AR Credit Memos from Oracle Advanced Collections Disputes - Approval via AME"

I created a AR Transaction batch source "XXX_Collections". Now, once the dispute is approved, Credit Memo workflow will trigger and create Credit memo lines in AR auto invoice interface table.

How does system understand which transaction source to pick. Where exactly do i need to mention my above transaction batch source?

Also, does anybody have a whitepaper or document on all steps required for creation of AR Credit memos via AME from Oracle Advanced collections disputes.

Regards,
