I have a very basic question with the Microsoft CRM 4.0 Report wizard. I am very experienced in SQL syntax and database queries, but I have no knowledge of MS CRM and SSRS.
I was helping someone create a SSRS report via the CRM wizard tool, and I'm trying to understand what the "Primary record type", and the "Related record type" is. In the Report Wizard. There is a page that mandates that you select a "Primary Record Type" in a populated drop down list. This drop down list is filled with the tables in the database (I believe). There is also an optional "Related Record Type" field that is filled with the tables.
What are these "Types"? Behind the scenes, how are these joined?
