How to filter parts thar are in specific location, if there are multiple locations for item?

[MrShippeR]

Hello community!
I'm here for advice.

Situation and settings:

We have a sub-warehouse managed in the PartDB software. Parts that come to our warehouse are sent from the central warehouse.

So I created two locations for each item in PartDB. The first location is kept as "rack number / shelf number". The second location is "incoming".

My idea of ​​use:

When the central warehouse is to send parts to the sub-warehouse, the central warehouse searches for the part in PartDB and clicks the plus button next to the "incoming" location.

When we physically receive the parts at the sub-warehouse, we filter out all items in the "incoming" location in the PartDB system that have a number of items greater than zero. We physically place the part to the rack and click the transfer button in the part detail. From the "incoming" location to "rack number / shelf number". This way we can check if the part amount match.

My question:

How to filter out items in the "incoming" location that have a number of items greater than zero in the incoming location?
Ideally, I would like to know how to click it in form. In the worst case, give me part of the link - I would save the link to Favorites in the browser.

In the current filter there is only the Total quantity item. Which is the sum of the items in the location "rack number / shelf number" and "incoming". Ideas? Or should I use the system in a different way?

Thank you very much.
