Questions [Solved] Adding column for intercompany eliminations

Hi!  We are trying to create a consolidated financial statement showing several companies in separate columns with an intercompany eliminations column that points to specific GL accounts for specific companies.  I have tried adding a row in the rowset with a Column Group that matches the Printing Group in the column set for the Eliminations column, but nothing populates in the eliminations column.  I thought maybe because I have column Type set to GL with nothing set in my Data Source, as I can't set the Data Source to a specific branch/general ledger because it needs to point to different GL accounts for different companies.  There are only 10 eliminations.

Please let me know if you can provide any tips or corrections, as I'm a newbie and might be missing something very obvious.  Thanks for all your help!
