One of my application is built on Pega PGP framework and as part of this framework I am trying to extend Business Data Modal that is shipped as part of the product. While I am trying to add few attributes that are present as part of one page list subscript 1 directly in the report definition it is throwing error. I know we need to create Declare index but I want to check by configuring it and adding data in DB table directly. 

But the default DataTableEditiorReport that is shipped as part of Pega PGP contains directly the page list in the report definition with subscript. Not only pagelist infact there are properties that are present with Page as well. Leave about adding page list or page properties, when I am trying to configure Single value properties from Edit Column it is throwing errors stating issues on few of the items.

I checked entire product there are no declare index rules associated with this. Not sure how these are saved. 

Can some one assist or throw information on how to resolve the issue. Attaching the document that contains screen shots of the errors and data modal of Business Data Type.
