CNV_20100250 - Details

• The SAP error message CNV_20100250 typically occurs during the process of merging General Ledger (G/L) accounts with secondary cost elements in the context of a migration or conversion project, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that there is an attempt to merge a G/L account with a secondary cost element due to a merge in the existing Chart of Accounts (CoA).
