Another piece of the puzzle of setting up an AsciiOutput is to define a view and then export that view.
Why would you do this? Well, you can either go through a series of IF statements in your metadata or data tab checking each record to see if it satisfies a long list of criteria (e.g. if the Account is Sales and if the Scenario is Actual etc.), or you can define a view in the prolog and then use that view for the AsciiOutput.
Syntax of DataSourceCubeView
The syntax is DatasourceCubeview=’ViewName’; – very simple eh!
The trick here is to define your view in the TI, then set the data source to this view.
