Sales Order line items line sequence numbers and AR invoice line sequence numbers are different

Hi,

Sales order is created for 4 items as like below.

Line no. 1.1 - Item Name A

Line no. 2.1 - Item Name B

Line no. 3.1 - Item Name C

Line no. 4.1 - Item Name D

But the AR invoice generated the line sequence no. is different while compare with sales order line, AR invoice is shown like below.

Line no. 1 - Item Name C

Line no. 4 - Item Name D

Line no. 3 - Item Name B

Line no. 2 - Item Name A

It is standard behaviour? or any profile available to achieve this?

Regards,

Shiva.
