  Cause:
  This error occurs when you attempt to block multiple documents (such as invoices, purchase orders, or accounting documents) for payment or processing, but some of the documents cannot be blocked due to certain conditions or inconsistencies.

  The document is already blocked or cleared.  
  The document is in a status that does not allow blocking (e.g., already paid, reversed, or locked by another process).  
  Missing or incorrect data in the document that prevents blocking.  
  Authorization issues where the user does not have permission to block certain documents.
