• SAP Error Message:
  W4091 & : & dependent batch records exist
  
  Meaning / 
  Cause:
  This warning message typically occurs when you attempt to delete or change a material batch, but there are dependent records linked to that batch in the system. These dependent records could be related documents, stock postings, quality inspection lots, reservations, or other transactional data that reference the batch.
  In other words, the system prevents you from deleting or modifying the batch because it is still referenced elsewhere, ensuring data consistency and integrity.
  
  Common Scenarios:
  
  Trying to delete a batch that has stock postings or inventory movements.
  Attempting to change batch master data when batch is linked to open reservations or production orders.
  Deleting a batch that is referenced in quality inspection lots or inspection results.
  Batch is linked to sales or purchase documents.
  
  
  Solution / How to Resolve:
  
  
  Identify Dependent Records:
  
  Use transaction codes like MSC3N (Display Batch) to check batch details.
  Use MB51 (Material Document List) or MB52
