• What is the cause and solution for SAP error message /ISDFPS/MM726 - Batch &1 for material &2 already exists and is ignored ?

  The SAP error message /ISDFPS/MM726 indicates that there is an attempt to create or process a batch for a material that already exists in the system. This error typically occurs in the context of batch management in SAP, where each batch of a material must have a unique identifier.
  Cause:
  
  Duplicate Batch Entry: The batch number you are trying to create or process already exists for the specified material.
  Incorrect Batch Number: The batch number may have been entered incorrectly, or there may be a misunderstanding about the batch number's uniqueness.
  Data Migration Issues: If data has been migrated from another system, there may be duplicate batch numbers that were not properly handled.
  System Configuration: The system may be configured to enforce strict batch number uniqueness, leading to this error when duplicates are detected.
  
  Solution:
  
  Check Existing Batches: Verify if the batch number already exists for the specified material. You can do this by using transaction codes like MMBE (Stock Overview) or MSC3N (Display Batch).
  Use a Unique Batch Number: If the batch number is indeed a duplicate, you will need to create a new batch with a unique identifier.
  Review Batch Management Settings: Ensure that the batch management settings in your material master are correctly configured. You can check this in the material master record (transaction MM02).
  Data Cleanup: If this issue arises from data migration, consider cleaning up the data to remove duplicates or adjust the batch numbers accordingly.
  Consult Documentation: Review SAP documentation or notes related to batch management for any specific configurations or known issues that might be relevant to your situation.
