Description:
This blog describes about the creation of a BRF+ application dynamically using CL_FDT* classes collection.
Pre-requisites:
1. Basic knowledge on OO ABAP concepts
2. Basic knowledge on BRF+ framework
Requirement:
Creation of BRF+ Application through a Simple report.
Interfaces Used:
1.if_fdt_factory
2. if_fdt_application
Here is the code snippet.
Step-1: Paste the below in your report. Each step in the code is explained in detail through comments.
DATA: lo_factory TYPE REF TO if_fdt_factory,
lo_application TYPE REF TO if_fdt_application,
lt_message TYPE if_fdt_types=>t_message,
lv_message TYPE string,
lv_boolean TYPE abap_bool,
lv_demo_appl_id TYPE if_fdt_types=>id,
lv_string TYPE string.
PARAMETER: pv_lcl TYPE abap_bool RADIOBUTTON GROUP r00 DEFAULT 'X',
pv_sys TYPE abap_bool RADIOBUTTON GROUP r00,
pv_mstr TYPE abap_bool RADIOBUTTON GROUP r00.
* get a reference to the instance of the factory
lo_factory = cl_fdt_factory=>if_fdt_factory~get_instance( ).
* =============================================================
* definition of the new application:
* get an initial application object from the factory
lo_application = lo_factory->get_application( ).
lo_application->if_fdt_transaction~enqueue( ).
* set values for the application, especially the name is important
* You need to have a unique name for each application, here we use the
* FDT Service class method to get the unique name.
lo_application->set_application_component( 'BC' ). "#EC NOTEXT
lo_application->set_software_component('SAP_BASIS'). "#EC NOTEXT
lo_application->set_development_package( '$TMP' ). "#EC NOTEXT
*If you want the system to generate a unique name for you application
*Uncomment the below three lines
*data lv_name type if_fdt_types=>name.
*lv_name = cl_fdt_services=>get_unique_name( ).
*lo_application->if_fdt_admin_data~set_name( lv_name ).
*Provide a user defined name to your application
lo_application->if_fdt_admin_data~set_name( 'Sample_app' ). "#EC NOTEXT ------------------------------"Sample_app" is the application name.
* In FDT terms there are 3 different type of Applications, Local application,
* system pplication and MasterData Application. The following lines shows how you
* can create local Application, masterdata Application and system Application.
IF pv_lcl EQ abap_true.
lo_application->create_local_application( ).
ELSEIF pv_sys EQ abap_true.
lo_application->create_system_application( ).
ELSEIF pv_mstr eq abap_true.
lo_application->CREATE_MASTERDATA_APPLICATION( ).
ENDIF.
*To activate the application and you can see the error messages in lt_message if any errors occurred during activation
lo_application->if_fdt_transaction~activate(
IMPORTING et_message = lt_message
ev_activation_failed = lv_boolean ).
IF lv_boolean EQ abap_true.
* for some reason the activation failed -> individual handling needed
lo_application->if_fdt_transaction~dequeue( ).
ELSE.
lo_application->if_fdt_transaction~save( ).
lo_application->if_fdt_transaction~dequeue( ).
* usually it makes sense to store the id for later access to the application
lv_demo_appl_id = lo_application->mv_id.
ENDIF.
WRITE: 'The ID of the application created is: ', lv_demo_appl_id. "#EC NOTEXT
Step-2: Click on execute button.
Step-3: You can see the below selection screen. There are three types of applications in BRF+.
1. Customizing/Local Application
2. Master data Application
3. System Application
Step-4: Select the type of Application you want to create and Click on execute button.
Step-5: Copy the generated Application ID.
Step-6: Goto BRF+ workbench.
Step-7: You can see the below workbench logon page in your default browser. Provide the User credentials and Click on "Logon" button as shown below.
Step-8: You can see the application created in the workbench with the properties provided in the report.
You are done with creation of a BRF+ application dynamically.
I will continue posting blogs for dynamic creation of Data Objects, Expressions, Rules and Rulesets very soon.
