The SAP error message CNV20400213 indicates that there is a conflict during a data migration or conversion process, specifically related to the handling of fields during a split and merge operation. This error typically arises in the context of SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other data conversion tools.
Cause: The error message "Field &1-&2 is excluded from the split, but converted in the merge" suggests that: A specific field (denoted by &1 and &2) is not included in the split operation, meaning it is not being processed or separated out during the data migration. However, this same field is being processed during the merge operation, which is likely causing a conflict or inconsistency in the data handling. This situation can occur due to: Misconfiguration in the migration settings. Inconsistent mapping of fields between the source and target systems. Incorrectly defined rules for how data should be split and merged.
