Process documentationCreating Wires In Wiring Schema

 

The wires in the wiring schema enable you as the application developer to connect the different UIBB configurations within an FPM application. The runtime interdependencies between UIBBS are defined by configuration entries called wires.

Prerequisites

In the SAP development system, you have created a Web Dynpro application and created an initial screen. For more information, see:

Process

The figure below illustrates the wiring process and is followed by explanation:

Note Note

The basic concept of wiring is to link one UIBB to other UIBB. The data flows from the source UIBB to the target UIBB through the connector class /BOFU/CL_FBI_CONNECTOR. In case the source UIBB is a Form UIBB the Collection arrow is used for connecting the UIBBs through the wire. In case the source UIBB is a list UIBB the Selection arrow should is used to connect the UIBBs.

End of the note.

  1. To complete the wiring, on the Wire Schema tab, choose the Graphical Wire Editor .

  2. Select the UIBBs under Available UIBBs.

  3. Drag and drop the UIBBSs to the panel on the right-hand side. The configuration box, has two arrows, Selection and Collection , that you use to move data to other UIBBs.

  4. Select the Collection arrow of the initial screen box and join it to the arrow head on top of the bootstrap form.

  5. In the Connector Details dialog box, select /BOFU/CL_FBI_CONNECTOR as the connector class.

  6. Connect the Collection arrow of the bootstrap form to the arrow head of the main form UIBB.

  7. In the Connector Details dialog box, select /BOFU/CL_FBI_CONNECTOR as the connector class.

  8. Similarly complete the wiring for other UIBBs if any.

  9. Choose the Done button. The configuration screen appears.

  10. Save the component configuration.
