Hi Anbu B,
Transaction swo1
1) Create Object type: some name starting with Z
2) Add interface IFSAP to the object.
3)I have added one attribute: key field of the Z table where data is hold.
4)I have implemented the method: ExistenceCheck. I check existence of the guid in my data table.
SELECT SINGLE vguid INTO lv_dummy_vguid FROM ztable WHERE vguid = lv_vguid.
IF sy-subrc <> 0.
exit_return 0001 space space space space.
ENDIF.
I am not shure, because i did not tested it but maybe points 3) and 4) are not obligatory, maybe you could omit them.
Best regards,
Rosen
