Can you clarify the question please - are you saying you are calling the function module from a program, and then testing sy-subrc after the call? If so, then your function module needs to have a list of exceptions defined and then you use "raising <i>my_exception_name</i>." within the FM code and test this in your calling program e.g.

      CALL FUNCTION 'DYNP_VALUES_READ'
        EXPORTING
          dyname               = l_dyname
          dynumb               = l_dynumb
        TABLES
          dynpfields           = lt_dynpfields
        EXCEPTIONS
          invalid_abapworkarea = 1
          invalid_dynprofield  = 2
          invalid_dynproname   = 3
          invalid_dynpronummer = 4
          invalid_request      = 5
          no_fielddescription  = 6
          invalid_parameter    = 7
          undefind_error       = 8
          double_conversion    = 9
          others               = 10.
 
  case sy-subrc.
    when 0.
      write: / 'all is good'.
    when 1.
     write: / 'invalid_abapworkarea found'.

etc

Hi Venkat..

If i understood your question correct.. you are talking about the PATTERN button in the abap editor..

You are trying to add the code for calling your function module using the pattern button and it is not giving the statements for sy-subrc check while adding the code to your program.. am i right???

If i am correct.. The only possibility for this is... that your funtion module has no Exception..

When a function module has no exception defined, then it never changes the value of sy-subrc and thus the sy-subrc check after call to such a function module is not necessary..

Due to this.. while using patter you do not get the sy-subrc check lines..

Thanks and Best Regards,

Hello Venkat,

Since you have created the function module, then im sure that you haven't defined any exceptions

Edit your function in SE37 and click on the exceptions tab

here you can define exceptions. after doing this, saving and activating it, try calling it again with the Pattern button

Hii. Venkat..

Only when you add Exceptions while Creating FM , The system will add this condion (IF SY-SUBRC <> 0) while calling the FM using Pattern.

So Create the Exceptions if necessary if ur FM.

Otherwise it is not mandatory to check the Sy-subrc.
