Product hierarchy is picking wrongly

Hello,

When i create Invoice ,i could not post invoice to accounting.

Characteristic value LC072R389S0231PL does not exist for characteristic PRODH (Prod.hierarchy)

Message no. KE0C133

Diagnosis

The characteristic "PRODH" ("Prod.hierarchy") should be posted to Profitability Analysis (CO-PA). When the system checked the entries, it was established that the transferred characteristic value (" LC072R389S0231PL") is not valid in CO-PA.

But in material master product hierarchy is LC072R387S0231PL.I dont know this is getting changed.

Thanks,

Pradeep M
