How is this possible? i can't see scripts running so cant understand how it's populating with non-sequential numbers. no editing is done on these transactions on import

line id doesnt need to be sequential. it should just uniquely identify the line on the transaction. items composed of other items like kit, assembly, and group items can cause line ids to increment by more than 1

I'm importing a sales order with a normal inventory item and it still is randomly populating a number and not starting at 1. If i try and initialize say an RGA from the Sales Order the line numbers do not match which causes a failure on the item receipt

i dont think the item receipt is supposed to match the line ids from the sales order

ideally i want to force the line ID to be sequential - May just have to create (another) custom field to do this

that said, although there is no requirement that the line id start at 1, i have yet to see it start at 7

7 was an example, i've seen it happen with 3 lines where the line number go from 1 2 5 and there are n scripts which are causing this to happen - It's strange. i've logged to NS Support. to investigate
