JobPick List - and working with external data sources

Hi All,

I want to add two table in our custom data definition but epicor wont allow to have Part Bin table because it already exits. So I decided to create a file dns and create a sub report and call part bin ,I want to know which parts have substitute parts and how much.

My question is what would be more secure options, I want to avoid having the dns file in every pc, SSRS is not an option at the moment.
