This error typically arises in the context of Material Requirements Planning (MRP) when the system is trying to calculate or display inventory levels, and it finds that the ADU value is not valid.
  Cause:
  
  Negative Inventory: The most common cause is that the system is trying to process a situation where the inventory levels have gone negative, which is not allowed.
  Incorrect Configuration: There may be incorrect settings in the material master data, MRP area, or related configuration that leads to an invalid ADU calculation.
