Catch an Exception Code

[Former Member]

Hi,

I am new to abap and webdynpro.

This is all i have done so far.

1.) Create a FM that creates a record in database table.

2.) Create a service call in webdynpro to that FM

3.) Added views and code to the webdynpro.

Now my webdyn pro works great and it creates a record in table.

But i have a problem here. there is now way to find out if a record is written into table or now.

Supose if i give a same record which exists in database it doesnt show any error.

I have added this exception in function module. But i dont know how to find out if an exception happens.

Please help me in this regard.

Thanks,

Bala.

Hi Bala,

In WD4A, Exception handling in FM is same as We do in R/3. You can check sy-subrc after calling the function module.

Also you can raise error message by using web dynpro code wizard(control + F7 ) button:

Select Generate message radio button. You will find number of methods in F4. You can use them as per your requirement

Hi,

Check below code to catch exception

CALL FUNCTION 'HR_READ_INFOTYPE'
    EXPORTING
      pernr           = lv_pernr
      infty           = lc_infotype
      BYPASS_BUFFER   = 'X'
    TABLES
      infty_tab       = itab8_info
    EXCEPTIONS
      infty_not_found = 1
      OTHERS          = 2.
  IF sy-subrc EQ 1.

*  REPORT MESSAGE

    CALL METHOD
wd_comp_controller->gr_message_manager->report_t100_message
      EXPORTING
        msgid = lc_msgid
        msgno = lc_msgno_65
        msgty = lc_e.
  ELSEIF sy-subrc EQ 2.

*  REPORT MESSAGE
    CALL METHOD
wd_comp_controller->gr_message_manager->report_t100_message
      EXPORTING
        msgid = lc_msgid
        msgno = lc_msgno_88
        msgty = lc_e.


  ENDIF.

here sy-subrc is a variable which stores 0 only whn update is successful else it returns any other value....

regards
