• What is the cause and solution for SAP error message CO791 - Production cost collector exists - joint production is not allowed ?

  The SAP error message CO791 ("Production cost collector exists - joint production is not allowed") typically occurs in the context of production orders and cost collectors in SAP's Controlling (CO) module, particularly when dealing with joint production scenarios. This error indicates that there is an attempt to create or process a production cost collector for a joint production scenario, which is not permitted in the current configuration.
  Cause:
  
  Joint Production Configuration: The system is configured to handle joint production, but the production cost collector already exists for the specified production order or cost object.
  Cost Collector Settings: The settings for the production cost collector may not allow for joint production, leading to this error when trying to create or process it.
  Incorrect Order Type: The order type being used may not support joint production, or it may not be configured correctly in the system.
  
  Solution:
  
  Check Production Order: Verify the production order associated with the cost collector. Ensure that it is set up correctly for joint production.
  Review Cost Collector Configuration: Check the configuration settings for the production cost collector in the SAP system. Ensure that it is set up to allow joint production if that is the intended use.
  Adjust Order Type: If the order type does not support joint production, consider changing the order type or adjusting its configuration to allow for joint production.
  Delete Existing Cost Collector: If the existing cost collector is not needed, you may consider deleting it (if appropriate) and then attempting to create a new one that aligns with the joint production requirements.
  Consult Documentation: Review SAP documentation or consult with your SAP support team to understand the specific configuration settings related to joint production and cost collectors.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on joint production and cost collectors.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CO01 (Create Production Order), CO02 (Change Production Order), and CO03 (Display Production Order) to manage production orders effectively.
  Configuration Path: The configuration for production cost collectors can typically be found in the SAP Customizing Implementation Guide (IMG) under:
  
  Controlling (CO) -> Product Cost Controlling -> Cost Object Controlling -> Define Production Cost Collectors.
  
  
  
  If the issue persists after following these steps, it may be beneficial to engage with your SAP support team or a consultant who specializes in SAP CO to further investigate the configuration and settings in your system.
