Reproducing the Issue

  1. Go to the Purchase Requests and Orders work center
  2. Go to the Purchase Orders view
  3. Select the relevant Purchase Order
  4. You noticed that current number range for purchase order is assigned with old number


In general system assigns the purchase order number range in the sequence itself. if user deletes any purchase orders, then those numbers will not be there in the system and thus sequence number cannot be maintained. Currently the no gap control is there for supplier invoice but not for purchase orders. For purchase orders, system does not guarantee the sequential numbering or no gap numbering. But system assures that there will be no duplicate numbering. Since In Preparation purchase orders can always be deleted, the No Gap requirement cannot be fulfilled. So the lost number can be allocated at any point of time in future randomly.


The number generation for Purchase order like other business object projections permits the usage of buffers to avoid wastage of numbers. So No Gap or Sequential numbering is not designed for purchase orders.
