• What is the cause and solution for SAP error message CI002 - Material assignment to sub-operations not permitted ?

  The SAP error message CI002, which states "Material assignment to sub-operations not permitted," typically occurs in the context of production planning and control, particularly when dealing with production orders and routing in SAP. This error indicates that there is an issue with how materials are assigned to sub-operations within a routing.
  Cause:
  
  
  Routing Configuration: The routing may not be set up to allow material assignments to sub-operations. In SAP, materials can be assigned to operations, but not all configurations allow for sub-operations to have materials assigned.
  
  
  Sub-operation Definition: The sub-operation may not be defined correctly in the routing. If the sub-operation is not properly linked to the main operation or lacks the necessary settings, it can lead to this error.
  
  
  Material Master Settings: The material being assigned may have specific settings that prevent it from being used in sub-operations. This could be due to the material type or status.
  
  
  Production Order Status: If the production order is in a status that does not allow changes (e.g., released or completed), you may encounter this error when trying to assign materials.
  
  
  Solution:
  
  
  Check Routing: Review the routing for the production order. Ensure that the sub-operations are correctly defined and that the main operation allows for material assignments.
  
  
  Adjust Material Assignment: If the sub-operation is not meant to have materials assigned, consider assigning the materials to the main operation instead.
  
  
  Review Material Master: Check the material master data for the materials you are trying to assign. Ensure that they are configured correctly and are allowed for use in the context of the production order.
  
  
  Change Production Order Status: If the production order is in a status that does not allow changes, you may need to change its status to allow for material assignments.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific configuration settings related to routing and material assignments.
  
  
  SAP Notes and Support: If the issue persists, check for any relevant SAP Notes that may address this error or consider reaching out to SAP support for assistance.
  
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like CA01 (Create Routing), CA02 (Change Routing), and CO01 (Create Production Order) to review and modify routing and production order settings.
  Configuration Settings: Look into the configuration settings for production planning (SPRO) to ensure that the system is set up correctly for your business processes.
  User Exits and BAdIs: Sometimes, custom logic implemented through user exits or BAdIs can affect how materials are assigned. Review any custom code that may be impacting this functionality.
  
  By following these steps, you should be able to identify the cause of the CI002 error and implement a solution to resolve it.
