• What is the cause and solution for SAP error message SV015 - Target key must be different from source key ?

  The SAP error message SV015, which states "Target key must be different from source key," typically occurs in the context of data transfer or data mapping processes, such as during the use of the SAP Data Transfer Workbench or when performing data migrations. This error indicates that the system is trying to map or transfer data from a source key to a target key that is identical, which is not allowed.
  Cause:
  
  Identical Keys: The most common cause of this error is that the source key and target key are the same. For example, if you are trying to copy or move data from one record to another and both records have the same identifier, the system will throw this error.
  Configuration Issues: There may be issues in the configuration of the data transfer process, where the mapping of source and target keys is not set up correctly.
  Data Integrity Rules: The system enforces data integrity rules that prevent the same key from being used in both the source and target fields.
  
  Solution:
  
  Check Key Values: Review the source and target key values in your data transfer or mapping process. Ensure that they are indeed different. If they are the same, modify the target key to be unique.
  Adjust Mapping Configuration: If you are using a mapping tool or configuration, check the settings to ensure that the source and target keys are correctly defined and that they do not overlap.
  Data Validation: Before executing the data transfer, validate the data to ensure that there are no conflicts with keys. This can often be done through a pre-check or validation step in the data transfer process.
  Consult Documentation: Refer to SAP documentation or help resources specific to the module or tool you are using for additional guidance on key mapping and data transfer processes.
