Function to Decode Qualifiers, as on QPXPRLST (Advanced Pricing - Price Lists)

Afternoon, gurus!

To build a report for a user, I have been trying to understand how the QPXPRLST form decodes the Value From and Value To fields, based on a query against qp_qualifiers_v. I tried web searches from various angles, hoping that someone had done this before. No joy.

I finally bit the bullet. I got Forms Builder working, pulled down the FMB, and started rooting around. I find what appear to be function calls, which makes sense. There are references to QP_CON_ATTR_VAL.Get_Attribute_Code in several places. I cannot find such a function within the report, and it does not seem to be a database object. I am either missing it while it is right in front of me, or i am looking in the wrong places. Can someone point me in the right direction? (In case it is relevant, we are running EBS 11.5.10.2)
