  • What is the cause and solution for SAP error message /SAPAPO/FOT821 - Only 1 order is allowed in case of split or product change ?

    The SAP error message /SAPAPO/FOT821: Only 1 order is allowed in case of split or product change typically occurs in the context of Advanced Planning and Optimization (APO) when dealing with production orders or planned orders. This error indicates that the system has encountered a situation where it is trying to process multiple orders for a product change or split scenario, which is not allowed.

    Cause:

    1. Product Change or Split: The error arises when there is an attempt to create or process more than one order for a product that is undergoing a change or split. This is often related to production scheduling where a product is being switched from one variant to another or when splitting production runs.
    2. Configuration Settings: The system settings or configuration may restrict the number of orders that can be processed simultaneously during a product change or split.
    3. Order Overlap: There may be existing orders that overlap with the new order being created, leading to a conflict.

    Solution:

    1. Check Existing Orders: Review the existing orders for the product in question. Ensure that there are no overlapping orders that could be causing the conflict.
    2. Adjust Scheduling: If possible, adjust the scheduling of the orders to ensure that only one order is active during the product change or split.
    3. Configuration Review: Consult with your SAP Basis or APO configuration team to review the settings related to order processing during product changes. They may need to adjust the configuration to allow for the desired behavior.
    4. Error Handling: Implement error handling in your order processing logic to catch this error and provide a user-friendly message or alternative actions.
