• What is the cause and solution for SAP error message MFLE_TOOLS154 - MATNR_INT &1 in client &2 is a duplicate of an archived material number ?

  The SAP error message MFLE_TOOLS154 indicates that there is a duplicate material number (MATNR) in the system that corresponds to an archived material number. This typically occurs when you attempt to create or modify a material that has the same number as one that has already been archived.
  Cause:
  
  Duplicate Material Number: The material number you are trying to use is already associated with an archived material. In SAP, archived materials are those that have been removed from the active database for performance reasons but can still be referenced.
  Data Integrity: SAP enforces data integrity rules to prevent conflicts and ensure that each material number is unique within the system.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check for Existing Material:
  
  Use transaction code MM03 (Display Material) to check if the material number you are trying to create or modify already exists in the system, even if it is archived.
  If it exists, you may need to use a different material number.
  
  
  
  Unarchive the Material:
  
  If you need to access the archived material, you can unarchive it using transaction code SARA (Archive Administration). You will need the appropriate authorizations to perform this action.
  After unarchiving, you can review the material and decide whether to keep it or delete it.
  
  
  
  Use a Different Material Number:
  
  If the archived material is still relevant and you cannot unarchive it, consider using a different material number for your new entry.
  
  
  
  Consult with Your SAP Administrator:
  
  If you are unsure about the implications of unarchiving or changing material numbers, consult with your SAP administrator or a functional consultant who can provide guidance based on your organization's policies.
