  The SAP error message 29573, "Material for the sales order item cannot be changed," typically occurs when there is an attempt to change the material associated with a sales order item after it has been created. This error is often related to the status of the sales order, the material's configuration, or the business processes in place.
  Causes:
  
  Sales Order Status: The sales order may be in a status that does not allow changes, such as being confirmed, delivered, or invoiced.
