• What is the cause and solution for SAP error message /SAPAPO/SEQ840 - Order &1 with lot size &2 &3 will not be backflushed ?

  The SAP error message /SAPAPO/SEQ840 indicates that there is an issue with backflushing an order in the Advanced Planning and Optimization (APO) module of SAP. This error typically arises when the system cannot backflush the specified order due to constraints related to lot sizes or other configuration settings.
  Cause:
  
  Lot Size Issues: The order may have a lot size that does not meet the requirements for backflushing. For example, if the order's lot size is smaller than the minimum lot size defined in the material master or production version, backflushing will not be allowed.
  Order Status: The order may be in a status that does not permit backflushing (e.g., if it is already completed or closed).
  Material Master Settings: The material master may not be configured correctly for backflushing. This includes settings related to backflush indicators or production versions.
  Production Version: The production version assigned to the order may not be valid or may not allow backflushing.
  Missing Components: If the components required for backflushing are not available or not properly defined in the BOM (Bill of Materials), this can also lead to the error.
  
  Solution:
  
  Check Lot Size: Verify the lot size defined in the order and ensure it complies with the minimum and maximum lot sizes defined in the material master or production version.
  Review Order Status: Check the status of the order to ensure it is in a state that allows backflushing. If necessary, change the status to allow backflushing.
  Material Master Configuration: Review the material master settings for the relevant material. Ensure that the backflush indicator is set correctly and that the production version is valid.
  Validate Production Version: Ensure that the production version assigned to the order is correct and allows for backflushing.
  Check BOM and Components: Ensure that all components required for the backflush are available and correctly defined in the BOM. If components are missing, add them to the BOM or ensure they are available in stock.
  Consult Documentation: Refer to SAP documentation or consult with your SAP support team for specific configuration settings related to backflushing.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like CO02 (Change Production Order) or CO03 (Display Production Order) to check the order details.
  Material Master: Use transaction code MM03 to view the material master data and check the relevant settings.
  BOM: Use transaction code CS03 to display the BOM and ensure all components are correctly defined.
  Production Version: Use transaction code C223 to check the production versions and their settings.
  
  If the issue persists after checking these areas, it may be beneficial to consult with your SAP Basis or functional team for further investigation.
