• What is the cause and solution for SAP error message EM164 - References to more than one migration object in data record ?

  The SAP error message EM164, which states "References to more than one migration object in data record," typically occurs during data migration processes, particularly when using tools like the SAP Migration Cockpit or LSMW (Legacy System Migration Workbench). This error indicates that the data record being processed contains references to multiple migration objects, which is not allowed.
  Cause:
  
  Multiple Migration Objects: The data record you are trying to upload or migrate contains references to more than one migration object. Each migration object should be processed independently, and a single record should not reference multiple objects.
  Incorrect Mapping: The mapping of fields in the migration object may be incorrectly set up, leading to confusion about which migration object the data belongs to.
  Data Structure Issues: The structure of the data being imported may not align with the expected structure defined in the migration object.
  
  Solution:
  
  Review Data Records: Check the data records you are trying to migrate. Ensure that each record corresponds to only one migration object. If a record references multiple objects, split it into separate records for each object.
  Check Mapping Configuration: Review the mapping configuration in your migration tool. Ensure that the fields are correctly mapped to the appropriate migration object and that there are no overlaps.
  Data Cleansing: Cleanse the data to ensure that it adheres to the expected format and structure for the migration object. Remove any unnecessary references or fields that may cause confusion.
  Use Correct Migration Object: Ensure that you are using the correct migration object for the data you are trying to import. If you need to migrate different types of data, use separate migration objects for each type.
  Testing: Before performing a full migration, conduct a test migration with a small subset of data to identify any issues early on.
  
  Related Information:
  
  Migration Cockpit: If you are using the SAP Migration Cockpit, refer to the documentation for specific migration objects and their requirements.
