Error creating webservice from BRF+ application

Question

Hi,
I am creating a webservice for the BRF+ application that I created.
I entered following parameters,
Development Package: 
Local Package:   
Transport Request: 
Create Function Group:   
Function Group: 
Function Module: 
Prefix for Generated Object: 
Webservice Name: 
Webservice Short Text: 
Webservice Security Profile: 
I get the following error message, which I am unable to find the reason for. Please help.
Save all the objects before generating the webservice
Alternatively I will appreciate if I can have the code that is generated as part of webservice. I think there is more code than I found below from the blogs.
TRY.
  hand over some values into the context
    lo_context = lo_function->get_process_context( ).
    lo_context->set_value( iv_name  = 'GROSS_SALARY'   "#EC NOTEXT
                           ia_value = 25000 ).
  process the function
    lo_function->process( EXPORTING io_context = lo_context
                          IMPORTING eo_result  = lo_result ).
  get the result
    lo_result->get_value( IMPORTING ea_value = lv_string ).
    WRITE lv_string .
  CATCH cx_fdt INTO lx_fdt.
  error handling
    LOOP AT lx_fdt->mt_message ASSIGNING <ls_message>.
      WRITE / <ls_message>-text.
    ENDLOOP.
ENDTRY.
lo_function->if_fdt_transaction~dequeue( iv_deep = abap_true ).
My goal is to create a function module that can use the BRF+ application rules to determine result based on input entered.

Hi Kartik,
You will get the following error message, if you have done some changes and you have not saved before trying to generate the webservice.
Please save all the changes before trying to generate the webservice.
Also, if your goal is to just generate the function module, this can also be alternatively done, but not from the UI.
You can try the same by executing the method GENERATE_RFC of the class CL_FDT_WEB_SERVICE and pass the required inputs. The only differnece between both this method is that in the webservice method you also have to provide the webservice related attributes, whereas in the other method you do not have. This funcitonality has not yet been ex[posed on the UI.
Thanks and Regards
