I have came across following weird scenario:
We already created huge no.of materials of material type say ZABC with two valuation classes say 1100 and 1200(GL accounts for these VCs for different posting keys in OBYC settings are same). Account category reference for this material type is 0010.
After that we created new material type say ZPQR with new Account category reference 0025, and valuation class 1200 is linked with this ACR 0025. Because of this, valuation class 1200 disappeared from material type ZABC. In order to avoid inconsistency, we need to have valuation class 1200 linked with older material type i.e.ZABC.How we can do this ? What impacts must have happened in this period (from MM/FI) in the system, where valuation class get shifted from one material type(ZABC) to another material type(ZPQR)....please help us in this scenario.
