2. Review the LHS Entity drop-down list to select the entity that will become the left-hand side of the join.
3. Use the RHS Entity drop-down menu to select the entity that will become the right-hand side of the join.
4. (Optional) Click Filter to create a Filter expression for each entity involved in the join. Filters allow you to pick and choose which information to include in the join analysis. For information about creating expressions, see Using the Expression Builder.
5. Click Next.
6. Highlight an attribute from both the left-hand (LHS attribute) and right-hand (RHS attribute) sides and click Add Join.
