CR 2013 SP1 Version 14.1.1.1036

Table1 has a Modified_User_ID & a Created_By_User_ID.

The User_ID is linked to the table Users which has IDs & Names.

If I insert the Users table twice to link both Modified & CreatedBy User_ID to obtain their full names it duplicates the rows in my details.

Is there another way to look up BOTH Users Name in table Users from their IDs in Table1?
