Reference from a free business object to another free business object
To ensure correct drill down behavior in the Open Module, you should create a reference from one free business object to another free business object. You can do this by using a free field and configure it as a reference field.
Example
End users should be able to descend from free business object 1 at the second selection level to free business object 5 at the third selection level.
Procedure
1. In Field Definer, select Free business object 5 and set its status to Under construction.
2. In Field Definer, go to the Details selection level.
3. Select a free field and set the In use property to Yes.
4. In the Field type field, select Free 1.
5. Enter a translation for this field, for example Free BO 1, and save your settings.
You have now created a reference field that refers to free business object 1.
 | For more information on configuring a free field as a reference field, refer to the Modifying the field type section in Field Definer. |
6. Go back to the Business Objects selection level and set the status of Free business object 5 to Completed.
7. In TSIs , select Open Module.
8. Descend to the TSI selection level, and select the layout of Free step 5.
9. On the action menu, click > and set the status of the layout to Under construction.
10. Add the free field Free BO 1, which you added to > in Field Definer, to the layout.
11. Save your settings and then set the layout's status back to Completed.
