The SAP error message CNV_CMIS_A_20219 indicates a discrepancy between the number of records in a source table and a target table during a data migration or conversion process. Specifically, it states that the source table has a certain number of lines (records) while the target table has a different number of lines. This can occur in various scenarios, such as during data migration using the SAP S/4HANA Migration Cockpit or other data transfer tools. Cause The discrepancy can be caused by several factors, including: Data Filtering: Some records in the source table may not meet the criteria for migration and are filtered out, resulting in fewer records in the target table. Transformation Rules: If there are transformation rules applied during the migration, they may alter the number of records (e.g., merging records, splitting records). Data Integrity Issues: There may be issues with the data integrity in the source table, such as missing or invalid records
