• What is the cause and solution for SAP error message RU090 - No backflushed items found in need of posting ?

  The SAP error message RU090, which states "No backflushed items found in need of posting," typically occurs in the context of production order processing, particularly when dealing with backflushing of materials. Backflushing is a process where the system automatically deducts the materials used in production from inventory once the production order is confirmed.
  Cause:
  The error can arise due to several reasons:
  
  
  No Components Defined for Backflushing: The production order may not have any components that are set up for backflushing. This can happen if the components are not marked for backflushing in the material master or the BOM (Bill of Materials).
  
  
  Production Order Status: The production order may not be in a status that allows backflushing. For example, if the order is already completed or technically closed, backflushing will not be possible.
  
  
  Confirmation Issues: If the production order has not been confirmed properly, or if there are no confirmations that indicate the usage of materials, the system will not find any items to backflush.
  
  
  Incorrect Configuration: There may be configuration issues in the backflushing settings in the system, such as incorrect settings in the production version or the routing.
  
  
  Material Availability: If the materials required for backflushing are not available or have not been issued to the production order, the system will not find any items to post.
  
  
  Solution:
  To resolve the RU090 error, you can take the following steps:
  
  
  Check BOM and Material Master: Ensure that the components in the BOM are marked for backflushing. You can check this in the material master under the "MRP" view or in the BOM settings.
  
  
  Review Production Order Status: Verify the status of the production order. It should be in a status that allows for backflushing (e.g., "Released" or "In Process"). If the order is completed, you may need to create a new order or adjust the existing one.
  
  
  Confirm Production Order: Make sure that the production order has been confirmed correctly. You can do this by checking the confirmation documents associated with the order.
  
  
  Check Configuration Settings: Review the configuration settings for backflushing in the production version and routing. Ensure that the settings are correct and that backflushing is enabled.
  
  
  Material Availability Check: Ensure that the materials required for the production order are available in stock and have been issued to the order.
  
  
  Reprocess the Order: If necessary, you may need to reprocess the production order or create a new one to ensure that all settings and confirmations are correct.
  
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like CO02 (Change Production Order) or CO15 (Confirm Production Order) to check and manage production orders.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  Documentation: Refer to SAP documentation for detailed information on backflushing and production order processing.
  
  By following these steps, you should be able to identify the cause of the RU090 error and implement the necessary solutions to resolve it.
