3126574 - After running MRP, the available quantity is still negative.


After running MRP, no sufficient proposals (e.g. Planned order, purchase requisition) were generated.
i.e. the available quantity is still negative.




  1. Please check whether you are using safety stock and in SSCUI 102373, 'Share of safety stock' has been set greater than 0 in field 'Avail. safety stock'.
    If the MRP-relevant portion of safety stock is sufficient for covering the requirements, the system does not create any new proposals.
  2. You are using time phased planning due to which the proposal will only be generated per planning cycle .


For cause 1, reset the portion of shared safety stock then run MRP again.
