This error typically arises during the planning process when the optimizer is unable to make the necessary adjustments to stock levels due to constraints or settings in the system.
  Cause:
  
  Fixed Stock Levels: The product may have fixed stock levels defined in the planning settings, which restricts the optimizer from making changes to the stock.
  Planning Parameters: The planning parameters for the product may not allow for stock changes, such as minimum or maximum stock levels that are already being met.
  Production Constraints: There may be constraints related to production capacity, lead times, or other factors that prevent the optimizer from adjusting stock levels.

  Run the Optimizer Again: After making the necessary adjustments, rerun the optimizer to see if the error persists.
