CRM WebClient UI using context values to build URL for custom button

[former_member605921]

Hello Experts,

first things first: im a total beginner in the SAP-world and especially in CRM-world and would appreciate your help on my problem: I want to open a dynamically built URL, when clicking on a custom button that i created.

I have defined a URL and a LTX under SPRO -> Transaction Launcher. Then i have defined a logical link which uses my LTX.

After that i navigated to the view, where i want to place my button (BT266H_PRVC/HeaderDetails) and redefined

DO_PREPARE_OUTPUT:

create_buttons( ).

and EH_ONOPEN_URL:

IF lr_navigation IS BOUND .
* Navigate to transaction launcher using link id
lr_navigation->navigate( iv_link_id = 'XYZ' ).
ENDIF.

Now when clicking on the button i want to dynamically build a URL with the current BUAG_ID, BP_ID and contract account, which i hope are all known to the system at this point. For solving this problem i edited the method BUILD_OTHER_URL in my z-handler-class from my LTX. I tried the following approach (using global data context) which i found in some blogs, but that unfortunately don´t work for me:

lr_gdc = cl_crm_ui_data_context_srv=>get_instance( ).

CALL METHOD lr_gdc->get_data_attribute
EXPORTING
iv_name = 'BP_GUID'
IMPORTING
e_value = lv_partner_guid.

Or:

lr_gdc->get_entity( EXPORTING name = 'CURRENTCUSTOMER'
RECEIVING value = lr_entity )

In debugging i came to the conclusion that this approach won´t work, because the gdc is empty (maybe because im not using ICWebClient?!)

So basically i´m looking for help at the last steps of identifying and using the current business context and hope the aforementioned steps were done correctly.

Thanks in advance!
