How to Show Stock Items "Requiring Scheduling" - All Items Have Arrived

Good Morning,

WITHOUT using the “Mark for PO” feature, is there any way to create a filter showing which Service Orders are “Ready to Schedule”?

I have created a filter looking at the INSiteStatus table, ensuring that the QtyOnHand > 0 (for the specific warehouse). Which works great, except that it doesn’t look at all item rows. Meaning a Service Order may require three different Inventory Items, and my filter will show the Service Order as “Ready to Schedule” when just one item meets my criteria of QtyOnHand>0. 

I would like the filter to only show the Service Call as “Ready to Schedule” when ALL Inventory Items have a QtyOnHand>0. 

Any ideas would be appreciated.

Thanks,

Alec
