MEPO814 - Details

• The SAP error message MEPO814 indicates that there is an issue with the processing state of a purchase order or a related document that prevents further processing of a follow-on document, such as a goods receipt or invoice. This error typically arises in the context of the Materials Management (MM) module when dealing with purchase orders (POs) and their associated documents.
  
  Cause:
  The error can occur due to several reasons, including:
  
  Incomplete Purchase Order: The purchase order may not be fully processed or may be in a status that does not allow further actions (e.g., it might be blocked or in a draft state).
  Document Status: The document may be in a status that restricts follow-on documents. For example, if the PO is marked as "deleted" or "blocked," it cannot be processed further.
  Release Strategy: If the purchase order is subject to a release strategy, it may not have been released yet, preventing further processing.
