Introduction
In this article, let's walk through the steps to configure a relationship using Input Forms. For example, imagine that we have a number of Entities and Departments. A Department could be valid in all, some, or only one of the Entities. As there's no key or intrinsic relationship between Entities and Departments, the best solution is to create a Form to manually define the mapping.

Example
1. Create a Validation Model to define valid combinations of Dimension Members.
We called our Model Valid Entity-Dep and added the Entity and Department Dimensions.
2. Deploy the Application.
3. Create a Form in the Model to define the relationship. We named it Department-Entity.
4. Configure the Form with all Department Members on the rows and Entity Members on the columns.
Note: The axis placement of the Dimensions does not matter. You can have Entity on the rows and Department on the columns.
5. Create a special Admin Dashboard and add the Form.
An Admin Dashboard is just a regular Dashboard used for managing administrative settings and other configurations. For our purposes, we just need the Form and a way to Post data.
Note: Ensure you can write to the Dashboard App and Model.
6. Go to the App and enter a value in every intersection where a relationship exists between Departments and Entities.
7. Link our Validation Model to the Model you want to apply the relationship to.
8. In your target Form, go to Advanced > Relationship and click Add.
9. Select the Validation Model and click Add.
10 Select 
and choose Department.
Now only valid Departments are shown for each Entity.
