NWBC 5.0 and cl_lsapi_manager=>navigate_to_transaction with force SAPGUI on

[ŁukaszPęgiel]

Hello,

I've seen some discussion about how to open SAP GUI from Webdynpro application but none of them did not work as I intend in NWBC 5. There is no problem when using HTML GUI.

Ok, so maybe what I have done so far:

1) cl_lsapi_manager=>navigate_to_transaction with parameter force_sapgui on, result is that when I navigate to received url I receive sap shortcut to open/save . I can then open this shortcut and new window (not tab) of NWBC is open with SAP GUI an transaction called. Additionally once buton with action to open was used, it's not working for the next click

Code:

  data(lo_lsapi) = cl_lsapi_manager=>get_instance( ).

  cl_lsapi_manager=>navigate_to_transaction(

    exporting

*      sm59_alias      = sm59_alias    " SM59 Alias of remote system

      transaction     = 'MM03'    " Transaction Name

      navigation_mode = 0   " 0 - inplace / 1 - new window

*      parameters      = parameters    " Parameter List, e.g. customerID=4711 for Target Application

*      dynp_okcode     = dynp_okcode    " DYNP OK Code

       force_sapgui    = abap_true    " Force using of SAPGUI native, even in HTML client

    importing

      url             = data(url)

    exceptions

      error           = 1

      not_supported   = 2

      others          = 3

  ).

  if sy-subrc <> 0.

*   message id sy-msgid type sy-msgty number sy-msgno

*              with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

  endif.

  lo_lsapi->navigate(

   location      = url

   mode          =  '0'

  ).

2) when I use cl_nwbc=>url_construct with paramater html_client off and cl_nwbc=>url_launch then transaction is opened in new tab but with HTML GUI instead of SAP GUI

Code :

  cl_nwbc=>url_construct(

  exporting

    canvas_wda__client_type       = 'nwbc'

    canvas_transaction            = 'MM03'

    html_client                   = abap_false

    canvas__window                = cl_nwbc=>canvas__window__app

    receiving

    url                           = data(lv_url) ).

  call method cl_nwbc=>url_launch

    exporting

      url = lv_url.

3) cl_nwbc_sapgui_shortcut=>url and call method cl_nwbc=>url_launch then it does what it expect to do means creates sap shortcut and then acts like point 1)

Code:

  cl_nwbc_sapgui_shortcut=>url(

    exporting

       iv_transaction_code          = 'MM03'

       iv_gui_size                  = cl_nwbc_sapgui_shortcut=>sc_gui_size_maximized

       iv_reuse_existing_connection = abap_true 

       iv_server_relative_url       = abap_false 

    receiving

      rv_url                       = data(rv_url) 

  ).

  call method cl_nwbc=>url_launch

    exporting

      url = rv_url.

Now the question if it works the same at your installation or this is something wrong with mine? Maybe other version of NWBC are working differently here?

EDIT: I've also read about this possibility but would like to avoid it as not always we have underlying business object there, and I think that creation of dummy one for navigation purpose isn't the best approach.

Maybe also can take a look at it?

Hi Lukasz,

I would still argue that you are better of using the OBN method and just creating your business objects. This makes it very flexible as well.

I will give a try then to OBN method. In the meantime I've reinstalled NWBC and now the window to save sap shortcut does not appear anymore for points 1 and 3. Instead new SAP GUI window is open , but still this is not new tab in NWBC, but much more better than before.

Hi Lukasz,

You can also try this code snippet

data: lo_lsapi TYPE REF TO IF_LSAPI.

data: lv_location type string.

  lo_lsapi = cl_lsapi_manager=>get_instance( ).

          lv_location = 'ls-tr://QM01?RIWO00-QMART=Q1'.

             lo_lsapi->navigate(

                        location      = lv_location

                        mode          =  '1'

*                    history_mode  = iv_history_mode

                        title         = 'Create notification'

                         ).

The RIWO00-QMART is the screen parameter for the first screen in QM01.

Jakob,

this is the same like the 1) point which also creates ls-tr:// string. But to be sure I've tested again, and result is same for me.

I will test OBN solution but need some more authorization at the moment for that.

Hi Łukasz,

I tried to open the Transaction through OBN method its is opening the T.code but the F4 helps were not working  as mentioned in the snapshot.

Also tried through the methods 1,2 and 3 you have mentioend above, I am also getting to open the shortcut and new window (not tab) of NWBC is open with SAP GUI an transaction called.

Did you solved this issue. Please give your suggestions.

Thanks,

Nalla B.

Hello Nallasivam,

sorry but I haven't found other way to do it, but I really doubt that your problem is linked to the way you've opened the transaction.

Cheers
