I think there is no any instant way to handle Amortization of material price in standard SAP. If any body had done any kind of work around/process map for this scenario, then, kindly share the same.
Scenario : Material price is Rs.10. Amortization charges Rs.1 is applicable for delivery quantity of first 10,000 items. We can prepare pricing condition for Amortization, but the requirement is after delivery of 10,000 quantity, Amortization charges should not be applicable.
I have tested with inforecord scale but it is not a success as it is picking the Amortization condition only when PO quanity is excatly 10,000. If PO quantity is less than 10,000 then Amortization condition is not picking.
