Intercompany Report and Stage Table Questions

Lb = the label field at the data source level.  As far as the others I do not know.  Maybe set up an adaptor SQL to pull top 1,000 rows from the view and see if the data in the view helps you understand those columns.

Here is SQL for a data adaptor, just be sure to limit it to top 1,000 or a particular time or WF name.

SELECT TOP (1000) 
       [Wfk]

Do you mean Fs and not Fx? If so then that is FlipSign.
