You use a bootstrap feeder to send the globally unique identifier (GUID) from the initial screen to the main screen. Based on the GUID sent by the bootstrap, the corresponding data is retrieved from the Business Object Processing Framework (BOPF) business object (BO) and displayed in the main screen. FBI provides the class /BOFU/CL_FBI_GUIBB_BOOTSTRAP as the generic bootstrap feeder class.
In the bootstrap feeder class /BOFU/CL_FBI_GUIBB_BOOTSTRAP enter the following parameters:
Business Object : Name of the BO; for example, /BOFU/DEMO_SALES_ORDER
Node : Name of the node; for example, ROOT
URL Key Provider : /BOFU/CL_FBI_URL_KEYPROVIDER; this is appended to the key in the URL
Preselection Key Provider: /BOFU/CL_FBI_PRESEL_KEYPROVIDER; the GUID of the alternate key that you enter on the initial screen is provided by the preselection key provider. The preselection key provider transports the key to the next screen
