• What is the cause and solution for SAP error message CO598 - You cannot change quantity in pegged assembly (see order &) ?

  The SAP error message CO598 indicates that you are trying to change the quantity of a pegged assembly in a production order or a process order, but the system does not allow this change because the assembly is pegged to a specific requirement. This typically occurs in scenarios where the assembly is linked to a dependent requirement, such as a sales order or a planned order, and changing the quantity could disrupt the planning and execution of the production process.
  Cause:
  
  Pegged Requirements: The assembly is pegged to a specific requirement, which means that it is directly linked to a demand (like a sales order or a planned order). Changing the quantity could lead to inconsistencies in the demand and supply chain.
  Order Status: The production order may be in a status that does not allow changes, such as "Released" or "In Process."
  Configuration Settings: Certain configuration settings in the SAP system may restrict changes to pegged assemblies.
  
  Solution:
  
  Check Pegging: Review the pegging information for the assembly. You can do this by navigating to the production order and checking the pegged requirements. If the pegging is no longer valid, you may need to remove or adjust the pegging.
  Change Order Status: If the order is in a status that does not allow changes, you may need to set the order to a status that permits changes (e.g., "Created" or "Released" if allowed).
  Adjust Requirements: If the pegged requirement can be adjusted, consider changing the quantity at the source of the demand (e.g., sales order or planned order) instead of the assembly.
  Consult Documentation: Review SAP documentation or consult with your SAP support team for specific configuration settings that may be affecting the ability to change quantities.
  Use Alternative Methods: If you need to change the quantity urgently, consider creating a new production order with the desired quantity and adjusting the existing orders accordingly.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like CO02 (Change Production Order) or CO03 (Display Production Order) to view and manage production orders.

  User Authorizations: Ensure that you have the necessary authorizations to make changes to production orders and their components.
