• What is the cause and solution for SAP error message IW579 - Status change not possible: Order has external purchase requisitions ?

  The SAP error message IW579, which states "Status change not possible: Order has external purchase requisitions," typically occurs when you attempt to change the status of a maintenance order or production order that has associated external purchase requisitions. This situation arises because the system prevents status changes that could disrupt the procurement process linked to those requisitions.
  Cause:
  
  External Purchase Requisitions: The order has one or more external purchase requisitions linked to it. These requisitions are created for materials or services that need to be procured from external vendors.
  Status Restrictions: Certain status changes (like closing or completing the order) are restricted when there are outstanding purchase requisitions, as it may lead to inconsistencies in the procurement process.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Purchase Requisitions:
  
  Go to the transaction code ME53N (Display Purchase Requisition) and check the status of the external purchase requisitions linked to the order.
  Ensure that all necessary actions related to these requisitions are completed (e.g., they are converted to purchase orders, or they are no longer needed).
  
  
  
  Cancel or Delete Unnecessary Requisitions:
  
  If the purchase requisitions are no longer needed, you can delete or cancel them. This can be done in the ME52N (Change Purchase Requisition) transaction.
  
  
  
  Complete the Purchase Order Process:
  
  If the requisitions are still needed, ensure that they are processed correctly. This may involve converting them into purchase orders and ensuring that the orders are received and invoiced.
  
  
  
  Change Order Status:
  
  Once the external purchase requisitions are resolved (either completed or canceled), you should be able to change the status of the maintenance or production order without encountering the error.
