Credit Memo Creation workflow(ARCMREQ) customization

Hi,

I have a client requirement to customize the ARCMREQ workflow for the following

Oracle Advanced Collections allows users to place all or portion of invoice in dispute status. when an invoice is in Dispute the seeded dispute workflow automatically generates credit memo after the required approvals. The customization required is to prevent credit memo from being automatically generated i.e We need to dispute the customer invoice using the standard functionality of collections but to create credit memo manually.

for this customization, I saved the seeded workflow with a custom name and modified the new process(custom) by taking a copy of the original process(seeded). I want to know the setup steps in EBS where i should map this new custom process so that next time the workflow kicks off it picks the new custom process i added instead of the seeded AR credit Memo Aprroval request process.
