How can I extract the value of a Table Lookup attribute using the PI AF Extractor?

I’m working with the PI AF Extractor and facing an issue with Table Lookup attributes.

The Table Lookup attribute itself is being extracted correctly into the attributes table, but the value column always comes as “no data”, even though the attribute resolves normally inside PI System Explorer.

I would like to know whether there is any supported way to extract the evaluated Table Lookup value using the PI AF Extractor, or if the extractor does not currently resolve Table Lookup references during extraction.

Has anyone faced this issue or found a recommended approach to retrieve these values through the extractor?
