Dear Experts,
We have a need to change valuation class for a material for which there are lot of PO's, reservations, Inbound deliveries. Also lot of material issues have been done to production orders previously. Now as a pre-requisite to change valuation class, we have to delete all open PO's, inbound deliveries, reservations & hence clear all documents which are shown in display errors while changing valuation class. Also stocks to be made zero. Also new material code can not be used instead. please suggest is there any other way to change valuation class for such material.
