Zeegor

Simple Batch Programming in ABAP

When developing in an SAP system, sometimes it is helpful or necessary to call a transaction with a batch input table, simulating a user session directly via ABAP. In the past, this was a verbose, unintuitive process, culminating with CALL TRANSACTION 'MM03' USING bdc_table. Want to focus on a screen element? Four lines of code will append that action to your internal table, thank you very much.

Zeegor is a lightweight wrapper to make this process much easier. Zeegor is your assistant, plugging away at the UI the way you tell him, similar to Dr. Frankenstein's Igor, except with a 'Z' in front of his name because that is in the SAP customer namespace.

Installation

Install this project via ABAPGit.

Syntax

To create a new session, get an instance of ZCL_BDC_SESSION using static method new_transaction( tcode ).

Then use the following methods to perform UI actions: go_to_screen( screen )->in_program( progname ): These two methods must be chained. focus_on( screen_field ) fill( screen_field )->with( value ) set_okcode( okcode )

Finally, call run( ) with all its optional parameters and the transaction will execute.

Example

Here is an example of calling the class builder to display a class.

REPORT z_bdc_example.

START-OF-SELECTION.
  DATA: bdc TYPE REF TO zcl_bdc_session,
        class_name TYPE c LENGTH 30 VALUE 'CL_SPFLI_PERSISTENT'.
        
  bdc = zcl_bdc_session=>new_transaction( 'SE24' ).
  bdc->go_to_screen( '1000' )->in_program( 'SAPLSEOD' ).
  bdc->focus_on( 'SEOCLASS-CLSNAME' ).
  bdc->fill( 'SEOCLASS-CLSNAME' )->with( class_name ).
  bdc->set_okcode( '=WB_DISPLAY' ).

  bdc->run( screen      = zcl_bdc_session=>screen_show_err_only
            screen_size = zcl_bdc_session=>size_current ).

This same example is in the ABAP documentation as program DEMO_CALL_TRANSACTION_BDC, except it is 48 lines long.

Tables and Whatnot

To focus on or modify a table control, use the method row( ) like so:

bdc->fill( 'ITAB-FIELD' )->row( index )->with( my_value ).
bdc->focus_on( 'ITAB-FIELD' )->row( index + 1 ).

Contributing

There are no hard and fast rules for contributing. If you have a change that is within the scope of BDC, go for it.
