Internal Order Split Multiple line

Hello

1- We created an internal requisition with 1 line and added a quantity 10 from item X.

2- Order created and imported in Order Management.

3- We allocated/assigned range serials for items and transacted the line.

Now, in the Transaction —> Shipping form. we observed that the line has been splitted into 10 lines. while we expect to see only one line with 10 quantity!

is it a correct behavior? Also is the a way to keep the line consolidated ?

Thank you
