Suppose I have composite datawindow d_mydw with embedded datawindow, say it is dw_1.
dw_1 has an item say it myname.
With power script, I can power script to get the value like:
dw_1.GetItemString(dw_1.getrow(), "myname").
But I want write an expression in d_mydw for a text of st to access that value.
I try above code in expression window and verify it and get error: User function was not found.
How to access child report dw in expression?
