• What is the cause and solution for SAP error message WAUF_ADD026 - In quantity calculation, the planned quantity is assumed to be zero ?

  The SAP error message WAUF_ADD026 indicates that during the quantity calculation in a production or planning process, the system has assumed that the planned quantity is zero. This can occur in various contexts, such as production orders, sales orders, or material requirements planning (MRP).
  Cause:
  
  Missing or Incorrect Data: The planned quantity may not have been entered correctly in the relevant master data (e.g., material master, BOM, routing) or in the order itself.
  Planning Parameters: The planning parameters might not be set correctly, leading the system to calculate a planned quantity of zero.
  Material Availability: If the system determines that there is insufficient stock or capacity to fulfill the planned order, it may default to a planned quantity of zero.
  Configuration Issues: There may be issues with the configuration of the planning strategy or MRP settings that lead to this error.
  Status of the Order: The order might be in a status that does not allow for quantity calculations, such as being closed or completed.
  
  Solution:
  
  Check Master Data: Verify that the material master, BOM, and routing are correctly set up and that the planned quantities are defined.
  Review Planning Parameters: Ensure that the planning parameters in the MRP settings are correctly configured. This includes checking the lot size, safety stock, and reorder point settings.
  Analyze Stock Levels: Check the stock levels and availability of the materials involved. If there is insufficient stock, consider adjusting the stock levels or the planned order.
  Order Status: Ensure that the order is in a status that allows for quantity calculations. If necessary, change the status of the order.
  Run MRP: If applicable, run the MRP process again to recalculate the planned quantities based on the latest data.
  Consult Documentation: Refer to SAP documentation or help resources for specific details related to the error message and its context.
