  • What is the cause and solution for SAP error message CNV_20600_CHECK017 - Double mapping entry provided for source value &1 ?
    The SAP error message CNV_20600_CHECK017 indicates that there is a double mapping entry for a source value in a data conversion or migration process. This typically occurs during the execution of a data migration project, especially when using SAP's Conversion Tools or the SAP S/4HANA Migration Cockpit. Cause: The error arises when the same source value is mapped to multiple target values in the mapping configuration. This can happen due to: Duplicate Entries: The mapping table or configuration may have duplicate entries for the same source value. Incorrect Mapping Logic: The logic used to define the mapping may inadvertently lead to multiple target values being assigned to a single source value. Data Quality Issues: The source data may contain inconsistencies or duplicates that lead to this situation. Solution: To resolve the error, you can follow these steps: Review Mapping Configuration: Check the mapping configuration for the specific source value mentioned in the error message (&1). Ensure that each source value is mapped to only one target value. Identify Duplicates: Look for duplicate entries in the mapping table or configuration. You can use tools like Excel or SQL queries to identify duplicates based on the source value. Correct Mapping Logic: If the mapping logic is complex, review it to ensure that it correctly handles the source values without creating duplicates.
