Hi Shilpi,

I had the same error. I got round them by pulling parts of the FM out as below

call function 'CV120_DOC_GET_APPLICATION'

exporting

pf_dokar = ls_drad-dokar

pf_doknr = ls_drad-doknr

pf_dokvr = ls_drad-dokvr

pf_doktl = ls_drad-doktl

importing

psx_file = lv_file

exceptions

not_found = 1

no_auth = 2

error = 3

others = 4.

concatenate 'file://' lv_file-filename into lv_url.

lv_url2 = lv_url.

call method lo_window_manager->create_external_window

exporting

url = lv_url2

modal = abap_false

has_menubar = abap_true

is_resizable = abap_true

has_scrollbars = abap_true

has_statusbar = abap_true

has_toolbar = abap_true

has_location = abap_true

receiving

window = lo_window.

lo_window->open( ).

Hi,

I am getting dump while dispaying the file as external window.

Is there no way to solve the problem.

I have created the webdynpro and using the function module below. But i am getting error like GUI is not supported for that and failing on class cl_gui_frontend

Please let me know how can we do this :

This logic program below is used to open the file name when the user clicks the file name

In background, program should look for DOKAR, DOKNR, DOKVR and DOKTL from DRAD table where

DOKOB = u2018MARAu2018 (Hard code)

OBJKY = material from initial selection screen

Then these values are used for FM CVAPI_DOC_VIEW

Import Parameter:

PF_DOKAR = DRAD-DOKAR

PF_DOKNR = DRAD-DOKNR

PF_DOKVR = DRAD-DOKVR

Then get PFX file from export table

(Refer to test data u201CTest DMSu201D of function module CVAPI_DOC_VIEW).

if i get the contents of file then i will bind the propert with data but i am not getting the any function module for that .

Hi Shilp,

Did you break the code down into the 2 function modules as expressed above?

CVAPI_DOC_VIEW will dump with the error as you expressed.

So firstly try the code snippet above.

Also make sure you have the correct DRAD to pass in by doing a select on DRAD first. this is probably nothing to do with your issue. Just to make sure you have the correct data.

ls_link-dokob = gc_equi.

call function 'CONVERSION_EXIT_ALPHA_INPUT'

exporting

input = lv_matnr

importing

output = lv_matnr. "as you might require correct number of zeros.

select * from drad into table gt_drad

for all entries in lt_link

where dokob = lt_link-dokob

Regards

Bruce

and objky = lt_link-objky.

Hi Shilpi,

In that FM somewhere using some GUI Related statements like CALL SCREEN, CALL TRANSACTION like statements.

So that the error. You can't use that FM. Go to ST22 and find where you are getting this error. if that is GUI error

you can't use that FM.

Try to search for any another FM to meet your requirements or try to remove that stement by converting to ZFM and make changes according to your requirement.

Cheers,

Kris.

Hi,

Goto st22 and check where your are getting this error.

if not go to that FM search for any GUI related statements is there or not. or try alternate FM.
