My line detail only displays 1 inventory item of some SO

Hi all, can somebody please kindly help me?

I have to make a generation of monthly sales report. But here’s what happens, the list of those SOs are incomplete, just take a look at the total net sales and it’s too far. So I checked this first SO, and yes it has three inventory items, two of which are not listed here. I have filter for “released” but yes, three of them are all shipped and invoiced. It may be in my groupings? Could someone please kindly check my report file for me. I would appreciate any help, thanks a lot!

Regards,

Paula
