We are trying to use the Material group to valuation class assignment and have activated the user exit LMR1M002 as specified by SAP. There is something amiss in the setup though as we are still getting the error MR147 Account determination for entry GG01 WRX 1000 not possible.
Currently for WRX, the rule is with valuation class and then associated G/Ls are defined.
If I should be using Gen modification, please specify what should be input there.
Any help would be greatly appreciated.
