Hi,

I need to know if there is a user element called menu so that i can get the various links based on the role of the user. If no such element is there, can any one give me an idea on how to get that functionality working.

Hi,

I am pasting the code for the menu_action item.

I have a menu called India, under it two menu action items, city1 with ltext 'Guwahati' and city2 with text 'Leh'. In the onaction of city1 I have a method clickonghy and for onaction of city2 I have a method clickohleh.

These methods set a textview text to the following:

I also use a textview to display the texts 'Clicked on Guwahati' and 'Clicked on Leh' once you click on 'Guwahati' or 'Leh'.

The codes are:

method ONACTIONCLICKGHY .

DATA lo_nd_node TYPE REF TO if_wd_context_node.

DATA lo_el_node TYPE REF TO if_wd_context_element.

DATA ls_node TYPE wd_this->element_node.

DATA lv_text LIKE ls_node-text.

• navigate from <CONTEXT> to <NODE> via lead selection

lo_nd_node = wd_context->get_child_node( name = wd_this->wdctx_node ).

• get element via lead selection

lo_el_node = lo_nd_node->get_element( ).

lv_text = 'You Clicked on Guwahati'.

• get single attribute

CALL METHOD lo_el_node->set_attribute

EXPORTING

• index = USE_LEAD_SELECTION

value = lv_text

name = 'TEXT'

.

endmethod.

and....

METHOD onactionclickleh .

DATA lo_nd_node TYPE REF TO if_wd_context_node.

DATA lo_el_node TYPE REF TO if_wd_context_element.

DATA ls_node TYPE wd_this->element_node.

DATA lv_text LIKE ls_node-text.

• navigate from <CONTEXT> to <NODE> via lead selection

lo_nd_node = wd_context->get_child_node( name = wd_this->wdctx_node ).

• get element via lead selection

lo_el_node = lo_nd_node->get_element( ).

lv_text = 'You Clicked on Leh'.

CALL METHOD lo_el_node->set_attribute

EXPORTING

• index = USE_LEAD_SELECTION

value = lv_text

name = 'TEXT'

.

ENDMETHOD.

Hi Tenzin,

Hello,

Yes, there is a [menu UI element|https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.highlightedcontent?documenturi=%2fhelp%2fsdn_help_nw04s%2fsaphelp_nw04s%2fhelpdata%2fen%2f37%2f978b411fb4b05fe10000000a1550b0%2fcontent.htm] One way to do this is using authorization objects.

You can verify if the user has permission to the desired authorization object and if positive you can show the option. Another way is show all menu options and if the user doesn't have permission to the option you can show an error message.

Hi,

Please use the class CL_WD_MENU and CL_WD_MENU_ITEM for achieving your functionality.

By using graphical layout choose, UI element MENU_BAR, you can do this by right clicking the ROOTUIELEMENTCONTAINER.

First you right click and enter the MENU_BAR.

Then you right click on the MENU_BAR Ui element and insert Menu Einfugen(Menu).

Third you right click on the Menu and insert the menu option, which can be for example a menu action item.

In the onAction event of the menu action item, give your code for the desired functionality.

regards,

Prosenjit.

Hi,

When you right click on the ROOTUIELEMENTCONTAINER, you will get the MENU_BAR UI Element right below the LINK_TO_URL UI element. Please proceed like that. Post your further queries in the process here.

hi,

you have to right click on menu_bar ui element to add the menu.

then right click on the menu to add the menu action item.

then you have to write the code for that action item.

its like you add menu countries(menu bar), then a host of countries( each menu), and then the cities in individual countries(menu_action_item).

please leave your email id in case i am missing out your question.
