• What is the cause and solution for SAP error message NSDM_MM_MIG212 - Materials with changed base unit read in NSDM_MIG_MARA_ME: &1 ?

  The SAP error message NSDM_MM_MIG212 typically occurs during the migration process when there are materials in the system that have had their base unit of measure changed. This can lead to inconsistencies or issues during data migration, particularly when the system expects a certain base unit of measure for materials.
  Cause:
  The error is triggered when the migration process encounters materials that have a different base unit of measure than what is expected. This can happen due to:
  
  Changes made to the base unit of measure in the material master data after the initial setup.
  Inconsistencies in the data that are being migrated, where the base unit of measure does not match the expected values.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify Affected Materials: Use transaction codes like SE16 or SE11 to query the MARA table (Material Master) and identify the materials that are causing the issue. Look for materials with a changed base unit of measure.
  
  
  Review Changes: Check the change logs for the affected materials to understand when and why the base unit of measure was changed. This can be done using transaction code MM03 to view the material master data.
  
  
  Correct Data: If the change was not intended, you may need to revert the base unit of measure to its original value. If the change is valid, ensure that all related data (like stock levels, purchase orders, etc.) is consistent with the new base unit of measure.
  
  
  Update Migration Data: If you are using a migration tool (like SAP S/4HANA Migration Cockpit), ensure that the migration data reflects the correct base unit of measure for the materials being migrated.
  
  
  Re-run Migration: After making the necessary corrections, re-run the migration process to see if the error persists.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MM03 (Display Material), MM02 (Change Material), and SE16 (Data Browser) for data analysis.
  SAP Notes: Check for any SAP Notes related to this error message or migration issues. SAP Notes often provide specific guidance or patches for known issues.
  Documentation: Review SAP documentation on material master data management and migration processes to ensure compliance with best practices.
  
  If the issue persists after following these steps, consider reaching out to SAP support or consulting with an SAP expert for further assistance.
