• What is the cause and solution for SAP error message NSDM_MM_MIG210 - Delete existing NSDM_MIG_MARA_ME entries: &1 ?

  The SAP error message NSDM_MM_MIG210 indicates that there are existing entries in the table NSDM_MIG_MARA_ME that need to be deleted before proceeding with a migration or data transfer process. This error typically arises during the migration of material master data in the context of the New SAP Data Migration (NSDM) framework.
  Cause:
  The error occurs because the migration process is attempting to insert new entries into the NSDM_MIG_MARA_ME table, but there are already existing entries that conflict with the new data being processed. This situation can arise if a previous migration attempt was not completed successfully, leaving residual data in the migration tables.
  Solution:
  To resolve this error, you need to delete the existing entries in the NSDM_MIG_MARA_ME table. Here are the steps to do this:
  
  
  Access the SAP System:
  Log in to your SAP system where the migration is being performed.
  
  
  Use Transaction Code SE16N:

  Input the table name NSDM_MIG_MARA_ME and execute.
  
  
  
  Review Existing Entries:

  Make sure that you are aware of the implications of deleting these entries, as they may be part of an incomplete migration process.
  
  
  
  Delete Existing Entries:
  
  You can delete the entries directly from the SE16N interface if you have the necessary authorizations.
  Alternatively, you can use a custom ABAP report or a transaction like SE11 to delete the entries programmatically.
