• What is the cause and solution for SAP error message MEPO087 - Plant can no longer be changed ?

  The SAP error message MEPO087 ("Plant can no longer be changed") typically occurs in the context of purchasing documents, such as purchase orders or contracts, when there is an attempt to change the plant associated with a line item that has already been processed or is in a status that does not allow for changes.
  Cause:
  
  Document Status: The purchasing document may be in a status that prevents changes, such as being fully processed, released, or already delivered against.
