I am trying to create a generic datasource for loading a Non cumulative Infocube.
As far as I know, I need to select "opening balance" field in this datasource to enable initial loading of data to the InfoCube.
But I find that "opening balance" is not activated ( i.e. I cannot select it) for my generic DataSource.
Please tell me, how can i create Generic DataSource with "opening balance" option?
