Hi, All,

Can anyone tell me what i should do? Which bapi or normal FM should i use?

The condition is :

there is a outbound delivery screen, and we can input outbound delivery number to see details,

when u input the right number, there is a message box popup which says 'the outbound deliver exists', and if u input the wrong number, the message is 'sorry, xx not exist'.

Now i want to use service call to achieve this function.

but i do not which function can be used in service call.

Looking forward to ur reply.

Thank you very much.

Use the Function LIKP_READ

if there is entry it return the Information or else it will give the message.

Hi, Vijay,

Thank you for ur replay.

But when i use it, there is one error,that is

"The following error text was processed in the system AD1 : Exception NO_ENTRY_FOUND that Is Not Class-Based Occurred "

So what should i do to correct it?

Thank you .

After the Service call you have to make some changes to the excecute method.

comment the exception part.

based on likp node , you check the data and raise your own message using message manager.

after the function call you have to use the sy-subrc check .

CALL FUNCTION 'LIKP_READ'
    EXPORTING
      i_vbeln =                         attr_i_vbeln
      line_exist =                      wd_this->line_exist
"   importing
"      o_Answr =                         wd_This->O_Answr
    TABLES
      e_likp =                          stru_c_e_likp
    EXCEPTIONS
      no_entry_found =                    1.
* error handling
  CASE sy-subrc.
    WHEN  1.
*      RAISE EXCEPTION TYPE cx_wd_no_handler
*        EXPORTING
*          textid =        cx_wd_no_handler=>kind_old
*          old_exception = `NO_ENTRY_FOUND`.
  ENDCASE.
