Fact Box Provider ID


I have just looked at a Fact box in our system with the provider ID of 58 which i know links to the sales line ( i think) however none of the objects are numbered 58 so i am wondering where this comes from and how to find a complete list to when i create a new fact box i know where to point the provider ID. Could someone help please.

58 is a ID of the Sales Lines part in that page.

If you select SalesLines part and press properties then ID should be 58.
