MEPO087 - Details

• 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.
  Dependencies: There may be dependencies on the plant that have been established, such as stock movements, deliveries, or invoices that have already been posted.
  Configuration Settings: Certain configuration settings in the SAP system may restrict changes to the plant once certain conditions are met.
  
  
  Solution:
  
  Check Document Status: Review the status of the purchasing document. If it has been fully processed, you may need to create a new document or adjust the existing one through other means
