Assign Source and Destination Units

A connection requires a source unit and a destination unit. Use the Source Unit and Destination Unit buttons to make these assignments. All units in the model are available for assignment. You can assign only one source unit and destination unit. The source and the destination cannot be the same unit.

To assign source and destination units

1. Click Source Unit.

   The Select Source Unit dialog box appears.

   

2. From the Units list, select an appropriate source unit.

3. Click OK.

4. Click Destination Unit.

   The Select Destination Unit dialog box appears.

   

5. From the Units list, select an appropriate destination unit.

6. Click OK.

   Note: Because of the relationship that connections have with units and their parent transfer class, you cannot change the source or destination units. To change the source or destination unit for a connection, you must delete the existing connection and create a new connection.
