Currently a derivative table from an On-Demand Data Table doesn't update the derivative table's columns after loading new data
To reprodue the scenerio
1. created 2 On-Demand Data Tables from Information Links. call this Table A and Table B
2. created a Data Table, using "Existing data in analysis" and performed a Pivot transformation, using the Table A as the source table. Call this Table C.
3. added Columns From External Data, using existing the pivoted data in Table C to add columns to Table B.
4. Data shows up in externally added columns in Table B for the current data item, but then when triggering the On-Demand functionality to load new data into Tables A and B, the pivoted Table C and the external columns added to Table B are not updated automatically.
Enhancement request - Ability to update the data automatically
