LineNum when creating APInvoice

Hi all,

I just noticed that when creating an AP Invoice based on a PO, and then we add another line to this AP,

the LineNum in table PCH1 will skip.

I am currently using SBO2007 PL9.

Is it suppose to be like that ?

Step to reproduce (in UI):

1. Create a PO with 1 line.

2. Create an AP Invoice base on this PO.

3. Before posting this AP Invoice, add another line

4. Post the AP Invoice.

5. Query the database, we will have LineNum 0 and 2 instead of 0 and 1

Regards
