AX 4.0, Purchase Order: quantity fully invoiced but still appearing as ordered

[kranthi]

On transactions, I see 4 different rows: 3 are about the quantity charged in my inventory in 3 different time. The recepit field is “purchased”. I also see a row where the receipt field = ordered and I see the quantity = 292.

So these 4 transactions are related to that particular purchLine (same lot id)?

How the purchase order data has been entered(manual or through any other process)?
