Business Object Creation
In order to make GOS work with a custom program instead of a document, it is necessary to create a custom
Business object that implements interface IFGOSASERV. Once BO is created it must be set to released
status.
1. Run transaction SWO1 (Business Object Builder), choose an object name, select “Object Type”
radio button and press “Create” button.

2. A popup appears. Fill fields Object type, Object name, Name, Description and Program. Choose
Application = '*'. Leave Supertype blank.
3. In the main page position the mouse pointer on “Interfaces” and press F5 (add object). In the popup
choose interface IFGOSASERV
4. Add key fields by position on “Key Fields” and press F5. Choose table field TRDIR-NAME

5. Position on method GOSAddObjects and press F6 (redefine). Insert the following code:
DATA:
SERVICE(255),
BUSIDENTIFS LIKE BORIDENT OCCURS 0,
LS_BORIDENT type BORIDENT.
CLEAR LS_BORIDENT.
LS_BORIDENT-LOGSYS = SPACE.
LS_BORIDENT-OBJTYPE = 'ZGOS'.
LS_BORIDENT-OBJKEY = OBJECT-KEY.
APPEND LS_BORIDENT to BUSIDENTIFS.
SWC_GET_ELEMENT CONTAINER 'Service' SERVICE.
SWC_SET_TABLE CONTAINER 'BusIdentifs' BUSIDENTIFS.
6. Save and genetate Business Object. Set release status to “released”
