Changing Title FPM OVP at runtime

[stefan_kagelmacher]

Hi,

I want to change the title of my OVP Floorplan. But the correct way for OIF (IF_FPM_IDR) seems not to work:

data lo_idr TYPE REF TO if_fpm_idr.

data lo_fpm TYPE REF TO if_fpm.

lo_fpm  = cl_fpm_factory=>get_instance( ).
lo_idr ?= lo_fpm->get_service( cl_fpm_service_manager=>gc_key_idr ).

After this step LO_IDR is initial.

So I try IF_FPM_OVP. There are two methods GET_CURRENT_CONTENT_AREA and CHANGE_CONTENT_AREA. The second method has an attribute to change the title.

data lo_ovp type ref to if_fpm_ovp.

lo_ovp ?= lo_fpm->get_service( cl_fpm_service_manager=>gc_key_cnr_ovp ).

ls = lo_ovp->get_current_area( ).

ls-title = 'TEST'.

lo_ovp->change_content_area( ls ).

This application dumps at runtime, message "Configuration can not changed at this moment" (German "Konfiguration kann zu diesem Zeitpunkt nicht geändert werden").

Reason:

Method IF_FPM_OVP~CHANGE_CONTENT_AREA (CL_FPM_OVP)

Var: me->mv_changeable_by_application = abap_false (Var is initial at runtime)

--> Raise Exception

How can I change this parameter?

Can anyone help?

Best regards

Hello Stefan,

changing a content area via method IF_FPM_OVP~CHANGE_CONTENT_AREA is only possible with an Application Configuration Controller (AppCC). This AppCC must either be a WD component implementing WD interface IF_FPM_OVP_CONF_EXIT or an ABAP OO class implementing the ABAP OO interface IF_FPM_OVP_CONF_EXIT. The AppCC has to be specified in the OVP component configuration. The logic for changing the OVP content area title must be implemented in the interface method OVERRIDE_EVENT_OVP. It will be called by the OVP runtime at a certain point in time during the FPM event loop. An instance of interface IF_FPM_OVP will be passed as importing parameter to the method.

Another and easier way to change the content area title of the OVP is to use method IF_FPM_CNR_OVP->CHANGE_CONTENT_AREA_RESTRICTED. Here, you are not enforced to use an AppCC. The method can be called at any time during the FPM event loop. An instance of IF_FPM_CNR_OVP can be received in the way that you have described in your coding example above.

Best regards,

Jens

Hi stefan

I am changing the header of amy fpm page in the action of a button but its not working

.

   DATA : lo_ovp  TYPE REF TO if_fpm_cnr_ovp.
   data  lo_fpm_floorplan TYPE REF TO CX_FPM_FLOORPLAN.
   data ls_content_area TYPE iF_FPM_OVP=>TY_S_CONTENT_AREA.

    TRY.

        lo_ovp  ?= wd_comp_controller->go_fpm->get_service( 'CNR_OVP' ).
        IF lo_ovp IS BOUND.
          lo_ovp->get_current_content_area(
          RECEIVING  RS_CURRENT_CONTENT_AREA = ls_content_area

          ).


          lo_ovp->change_content_area_restricted(
          EXPORTING
            iv_content_area_id = 'PAGE_2'
            iv_title           = lv_title ).

        ENDIF.

      CATCH cx_fpm_floorplan INTO lo_fpm_floorplan.
    ENDTRY.

please revert back to me .

Hi prabhatirani ,

You can change the header title of fpm page by using the CHANGE_CONTENT_AREA method of interface IF_FPM_OVP with parameter IS_CONTENT_AREA.

In that you can set the field "title" , it will chane your header.

Note : You have to follow this approach if you changing this from APPCC . If you want to change from normal feeder  you have to get the instance of IF_FPM_OVP. Then you can use method CHNAGE_CONTENT_AREA.

Thanks

Just adding to Solution 2 mentioned by Jens on reply to Stefan, I have applied this (in my IF_FPM_GUIBB~INITIALIZE method) and it works for me. No AppCC needed.

Here's the code in case it's useful for anyone else:

DATA: go_fpm_ovp TYPE REF TO IF_FPM_CNR_OVP,
            ls_cont_area TYPE if_fpm_ovp=>ty_s_content_area.

         go_fpm_ovp ?= go_fpm->get_service(
                    iv_service_key = if_fpm_constants=>gc_service_key-cnr_ovp ).

         IF go_fpm_ovp IS BOUND.

    ls_cont_area-title = 'Your title'.

    ls_cont_area-id = 'PAGE_1'. "your area page id

    go_fpm_ovp->change_content_area_restricted(
        iv_content_area_id = ls_cont_area-id
        iv_title = ls_cont_area-title  ).

  ENDIF.
