Summary:

Please see below busness case if it can be fullfilled through the integration between AR and OM.

Sales Order with 4 units, unit price 1000, Total 4000 >> AR invoice would be generated in AR Module through Autoinvoice Process.

Apply a Credit Memo to the AR invoice in AR with -500, then Invoice Balance would be 3500   (3500/4=875 new unit price )

make Sales Order Return with 2 units Which in turn should create a Credit Memo in AR with 2 Units * 875 unit price = 1750 SAR (this is the expcted result, can we get this from the system through the integration between AR and OM?
