• What is the cause and solution for SAP error message /SAPAPO/SNP156 - You cannot create order: Order group & contains header order ?

  The SAP error message /SAPAPO/SNP156 indicates that you are trying to create an order in SAP Advanced Planning and Optimization (APO) that cannot be processed because the order group specified contains a header order. This typically occurs in the context of production planning and scheduling, where certain order types are not allowed to be created under specific conditions.
  Cause:
  
  Header Order Exists: The order group you are trying to use already contains a header order. In SAP APO, a header order is a higher-level order that groups together several subordinate orders (like production orders or purchase orders).
  Order Group Restrictions: The order group may have restrictions that prevent the creation of new orders if a header order is present.
  Configuration Issues: There may be configuration settings in the system that dictate how orders can be created and managed within the order group.
  
  Solution:
  
  Check Existing Orders: Review the order group to see if a header order is already present. If it is, you may need to either complete or delete the existing header order before creating a new order.
  Use a Different Order Group: If the current order group is not suitable for creating new orders due to the presence of a header order, consider using a different order group that does not have this restriction.
  Modify Order Group Settings: If you have the necessary permissions, check the configuration settings for the order group in the SAP system. You may need to adjust the settings to allow for the creation of new orders under certain conditions.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on managing order groups and header orders in APO.
  Contact Support: If the issue persists and you cannot find a resolution, consider reaching out to your SAP support team or consulting with an SAP expert for further assistance.
  
  Related Information:
  
  SAP APO Documentation: Review the official SAP documentation for APO, particularly sections related to order management and order groups.
  Transaction Codes: Familiarize yourself with relevant transaction codes in SAP that can help you manage orders, such as /SAPAPO/ORDERS for order management.
  User Roles and Permissions: Ensure that you have the appropriate user roles and permissions to create and manage orders in the system.
  
  By following these steps, you should be able to resolve the error and successfully create the necessary orders in SAP APO.
