My Question is from where inherits inventTable_qr. I’m interested what do “_qr”

You provided very little information, nevertheless I guess you have a form in AX 2012 that has a data source called InventTable and you want to know what’s the variable called inventTable_qr.

It’s an instance of QueryRun class linked to InventTable data source. It’s generated automatically by AX.

By the way, it has nothing to do with inheritance.

Yes exactly. Next time I give more info :slight_smile:
