The SAP error message CNV_20100256 indicates that there is a mismatch in cost centers within a controlling area during a data migration or conversion process. This error typically arises when the system detects that two or more entries (such as cost objects, internal orders, or other financial documents) are associated with different cost centers in the same controlling area, which is not allowed.
Cause: Data Inconsistency: The primary cause of this error is that the data being migrated or processed contains references to different cost centers that are not aligned within the same controlling area.
Configuration Issues: There may be configuration issues in the controlling area settings or in the cost center master data. Incorrect Mapping: During data migration, the mapping of cost centers may not have been done correctly, leading to discrepancies.
