Where-Used List in BRF Tables

The BRF can execute a where-used list for the BRF objects Expression and Action in the tables of the BRF. The main tables involved are:

• TBRF200 (Expression in Expression)

• TBRF240 (Expression in Event, Action in Event)

• TBRF259 (Expression in Action)

• TBRF290 (Expression in Rule Set, Action in Rule Set)

The where-used list always works in these tables.

Where-Used List in Application Tables

To be able to execute a where-used list of the BRF objects Expression and Action in application tables as well, you must ensure the following:

• The application searches in the application tables to see if they contain BRF objects.

• The application returns any hits that are found to the BRF.

Proceed as follows:

1. Implement the WHERE_USED method of interface IF_APPLCLASS_SERVICES_BRF in a class.

   The WHERE_USED method must provide the following information:

   • Table with the usages

   • Field catalog to display the results in an ALV tree control

   • Table with sort criteria

2. Store the class of the WHERE_USED method on the maintenance screen of the application class.

   Proceed as follows:

   1. Double-click to select the application class in the navigation tree of the BRF.

   2. Enter the class in the Details section in the General Services field.

   3. In the same section, set the Where-Used List Implemented indicator.

If you now call the where-used list in the BRF (see Where-Used List for an Expression or Action), the BRF also considers the tables of the application.
