This is done via the “Reusable Combo” set-up. You need to filter the second combobox by the value of the first…
In this example, I created a DataView called UD02_View which pulls in my data from UD02. This is where my customization is storing the final data.
I set the first drop down with binding to UD02_View.ShortChar19.
The Reusable Combo of the first drop down is being Filtered by the User Code “DWG_Source”.
My second combo is bound to ShortChar20… but in this case, you see my CodeTypeParam = whatever the value is from my ShortChar19.
