Sales order with allocation creates new Lot/serial number entry

Good day.

We have an enquiry regarding the creation of a sales orders with allocations.

We query the inventory summary results - expanded  by lot/serial number to retrieve a list of serials for an inventory product. We then display these options to the user to choose from when ordering a product ex: a gun.

It seems that when we create an order with an allocation it creates/duplicates the lotSerialNbr entry within the inventory summary.

Please see attached:

- Example of create order call from documentation

- Screenshot of our request logs

- Screenshot of additional lotSerial entries created

Our understanding of allocation on an order is that an existing lot serial number will be assigned to a Details/Product entry.

Would appreciate any clarification and guidance on why our request is in fact creating a new lot/serial entry for an inventory item.

Kind regards, 

Alecia
