• What is the cause and solution for SAP error message /SAPAPO/OM_ERROR2108 - Confirmed quantity at output/input node is negative/positive quantity ?

  The SAP error message /SAPAPO/OM_ERROR2108 indicates that there is an issue with the confirmed quantity at an output or input node in the Advanced Planning and Optimization (APO) module. This error typically arises in the context of production planning and scheduling, where the system expects certain quantities to be confirmed but finds discrepancies.
  Cause:
  
  Negative Confirmed Quantity: This can occur if there is an attempt to confirm a production order or a planned order with a negative quantity, which is not allowed.
  Positive Confirmed Quantity: Conversely, if the system is trying to confirm a quantity that exceeds the available capacity or stock, it may also trigger this error.
  Data Inconsistencies: There may be inconsistencies in the master data, such as incorrect settings in the production version, or issues with the bill of materials (BOM) or routing.
  Capacity Constraints: If the production capacity is not sufficient to handle the confirmed quantities, this error may arise.
  Order Status: The status of the production or planned order may not allow for confirmation (e.g., if the order is already completed or canceled).
  
  Solution:
  
  Check Confirmed Quantities: Review the confirmed quantities for the relevant orders and ensure they are within acceptable limits (i.e., not negative and not exceeding available capacity).
  Review Master Data: Verify the master data related to the production version, BOM, and routing to ensure they are correctly configured.
  Capacity Planning: Check the capacity planning settings to ensure that there is enough capacity available to handle the confirmed quantities.
  Order Status: Ensure that the order status allows for confirmation. If the order is in a status that does not permit confirmation, you may need to change the status or create a new order.
  Reprocess Orders: If necessary, reprocess the orders or run the relevant planning runs to update the system with the correct quantities.
  Consult Logs: Check the application logs for more detailed error messages or warnings that can provide additional context for the issue.
