OIC Multiple lines sales credit creation.

We came cross AR invoices with multiple sales credits but most of them are showing 0%. .

This is creating some issues in OIC.  OIC will collect all the sales reps even those with 0%. The sales credit allocation is done in OIC, so the sales credits in AR are ignored. What happens is that OIC will reverse all this lines during sales credit allocation. This will create unnecessary lines and may cause some confusion when OIC users are analyzing credited transactions in OIC.

Our understanding was only the customer sales reps will be in the AR invoice with 100% sales credit. Please clarify and advise.
