Scheduling Complexities with "Generate Receipt Advice". Workarounds? Alternate Approaches?

Summary:

Hi , We have a requirement to send Return order to details to WMS. We currently use standard Oracle functionality which is running ESS "Generate Receipt Advice" (Associated with "Create Return Transaction event") . However the ESS job requires Additional parameters to run apart from the Organization. The following Error is obtained "We need to provide either purchase order, in-transit shipment, transfer order, RMA, supplier, customer, item, or due date."

This generates limitations on Scheduling this job to run based on a particular frequency since we cant expect user to manually input RMA details everytime he requires to send RMA information to WMS.
