Hello,
I want to get the value of the property value Included Column of the data field Qty of the index TransIdIdx of CustInvoiceTrans below.

I was able to get the Datafield(Qty) with DictIndex.includedColumn, but I can't find a way to get the Included Column value of the property in the DictIndex class.
If anyone knows how to get it, could you share it?
Any advice would be appreciated.
