ABAP BAPI BO Class Code Generator – Business Object parameters

This blog post is a follow-up blog post of

In this post is explained what effect the Business object class parameters have on the generated code.

The example below will be used to explain the Business Object class selection screen parameters.

Business Object name

The Business Object name is used in messages to the user.

  • Existence check
     "Sales Order &1 does not exist.
     MESSAGE e001(zsd_sales_order)
       WITH key
       INTO DATA(lv_dummy##NEEDED.
  • In test class, for example...
     WRITE'sales order instantiated. '. 
     WRITE'sales order not instantiated. Error: '.

Module name abbreviation and the ABAP object name

These are used in:

  • Report name:
    REPORT zsd_sales_order_p.
  • Business Object Class interface name:
    INTERFACE zsd_sales_order_boi.
  • Business Object class name:
    CLASS zsd_sales_order_bo DEFINITION.
  • Test class name:
    CLASS zsd_sales_order_bo_tt DEFINITION.
  • Variable names
     DATA(_sales_order_bo) =
        _sales_order_crea_s ).
  • Message class name:
          MESSAGE e001(zsd_sales_order)
            WITH key
            INTO DATA(lv_dummy##NEEDED.

ABAP naming

You have two options

  • DSAG 2016 short naming
  • Long naming


Variable type DSAG 2016 short naming Long naming
Local structure  _sales_order_crea_s ls_sales_order_crea
Local reference  _sales_order_bo lr_sales_order_bo
Local Exception variable  _return_exc lr_return_exc
Global class element key gs_key
Global structure type  tcreate_data_s gts_create_data

BO main DB table

The database table is used for

The existence check

  •   METHOD check_existance.
            'X' AS exist_ind
          FROM vbak
          INTO @DATA(lv_exist_ind)
            vbak~vbeln @gs_key.
        IF sy-subrc <> 0.
  • It is also used for the key fields if the BOR object type is empty.

BOR object type

The BOR object type is used for determining the key fields.

Generate class interface indicator

This checkbox indicates whether a BO Class interface should be generated.

If not, than the data types and method declarations will be done in het BO Class definition.

      Nice blog.  I really like pictures.  Combined with the last blog it makes it very effective.

      Thank you,

      Hi thank you for the blog, between part1 and this blog, it has stirred quite some interest among my colleagues, since we often have to find ways to encapsulate certain "business object" abstractions into a simple to use format.

      So far we used function modules and some very timid use of Objects, but with your approach it is clear there are advantages for programs that interface with external systems or within custom workflow actions.


      And for the record, we prefer the long naming, DSAG is often too rigid for what we aim for.

      I must say a great blog. Infact i missed to read the earlier one and thanks to this blog i was able to understand the concept in detail. Adding an interface i think is great the signatures are uniform then. Thanks

      Thank you. Version 1.2 is now available and generates also the class interface.
