• What is the cause and solution for SAP error message NSDM_MM_MIG209 - ** &1 Materials with changed base unit inserted to NSDM_MIG_MARA_ME ?

  The SAP error message NSDM_MM_MIG209 indicates that there are materials in the system that have had their base unit of measure changed, and these materials are being inserted into the table NSDM_MIG_MARA_ME during a migration process. This error typically occurs during data migration activities, such as when using the SAP S/4HANA Migration Cockpit or other data migration tools.
  Cause:
  The primary cause of this error is that the migration process has detected materials that have had their base unit of measure changed after they were initially created. This can lead to inconsistencies in the data, as the migration process expects the base unit of measure to remain consistent for the materials being processed.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify Affected Materials: Use transaction codes like SE16 or SE11 to query the relevant tables (e.g., MARA, MBEW) to identify which materials have had their base unit of measure changed.
  
  
  Review Change History: Check the change history of the affected materials to understand when and why the base unit of measure was changed. This can be done using transaction code MM03 (Display Material) and reviewing the changes in the "Change Documents" section.
  
  
  Correct the Base Unit of Measure: If the change was made in error, you may need to revert the base unit of measure back to its original value. This can be done using transaction code MM02 (Change Material).
  
  
  Update Migration Data: If the change is valid and you want to keep the new base unit of measure, ensure that the migration data is updated accordingly. This may involve adjusting the migration templates or data files to reflect the correct base unit of measure.
  
  
  Re-run the Migration: After making the necessary corrections, re-run the migration process to see if the error persists.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration process you are using, as there may be additional considerations or steps specific to your scenario.
  
  
  Related Information:
  
  Migration Cockpit: If you are using the SAP S/4HANA Migration Cockpit, ensure that you are following the guidelines provided in the migration documentation.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Data Consistency: Always ensure that your data is consistent and that any changes to master data (like materials) are well-documented and justified.
  
  By following these steps, you should be able to resolve the NSDM_MM_MIG209 error and successfully complete your migration process.
