How to link datawindow to another datawindow

Hi All,

With PB 12.5 here.

I have a datawindow called d_locationpath, which is to query and combine parent and child location to get the location path (full directory), as below.

Fyi, I can't get this Location Path directly from database and that's why I create this datawindow to get it.

My question, how to link another datawindow to this d_locationpath datawindow to get Location Path based on Locationid?

Example:

d_stockitem has locationid and I would like to use this locationid to get Location Path in d_locationpath (where d_stockitem.locationid = d_locationpath.locationid).

Kindly advise.

Thank you in advance.

BR,

Yow
