• What is the cause and solution for SAP error message MDG_BS_MAT_ACCESS156 - Entries without EAN category were erased ?

  The SAP error message MDG_BS_MAT_ACCESS156 indicates that there are entries in the Material Master that do not have an EAN (European Article Number) category assigned to them, and as a result, these entries have been erased or removed from the system. This typically occurs in the context of Material Data Governance (MDG) processes where data integrity and completeness are critical.
  Cause:
  
  Missing EAN Category: The primary cause of this error is that certain material entries lack the necessary EAN category. EANs are essential for identifying products uniquely, especially in retail and logistics.
  Data Governance Rules: The MDG system may have specific rules or validations that require all materials to have an EAN category. If these rules are not met, the system may automatically delete or reject the entries.
  Data Migration Issues: If data was migrated from another system, it’s possible that the EAN category was not included or was incorrectly mapped.
  
  Solution:
  
  Check Material Entries: Review the material entries that triggered the error. Ensure that all materials have the required EAN category assigned.
  Update EAN Information: If the EAN category is missing, update the material records to include the appropriate EAN information. This can be done through the Material Master transaction (MM01, MM02) or through the MDG interface.
  Data Validation Rules: Review and, if necessary, adjust the data validation rules in the MDG configuration to ensure that they align with your business requirements. This may involve consulting with your SAP MDG functional team.
  Data Migration Review: If the issue arose during a data migration process, review the migration mapping and ensure that EAN categories are included and correctly mapped.
  
  Related Information:
