Error message with a hyperlink attached to it

Question

Hi Friends
I have a requirement wherein I need to display a hyperlink along with the error message in webui.
Example...
Please enter a valid currency Details
Here Details should appear as a Hyperlink and on clicking on this hyperlink it should navigate to a portal screen.
Infact it is not actually a portal screen, it can be any URL.
Could you please let me know how to add the hyperlink and how to navigate to portal screen on clicking on this hyperlink
where do we need to write the code.
Best Regards
Anil

Hi Anil.
According to SAP Help you can always get a link in a message for:
. Fields that are defined as mandatory in the UI Configuration Tool
. Fields that are defined as mandatory in the business object layer (BOL)
Also it's possible with additional coding. The example is:
lr_msg_service = view_manager->get_message_service( ).
lr_msg_service->add_message_mapping( iv_message_class = 'CRM_BRC_MESSAGES'
iv_message_number = '013'
iv_binding_string = '//BRCBUSINESSROLE/STRUCT.CRMUI_NAVBAR'
iv_page_id = component_id ).
Check this [link|http://help.sap.com/saphelp_crm700_ehp01/helpdata/EN/cb/659ebfc880493baad66896518a55a1/content.htm] for details. Look at "Navigation to Field That Issued a Message" section and related link for "Enabling Links in Messages".
Another option, which mentioned Arun and according [to this book|http://www.sap-press.com/products/SAP-CRM-Web-Client-Customizing-and-Development.html], is the global message service. The global message service enables you to register callback methods so that you can output navigable messages, that is, you can initiate a navigation to another view (or do whatever you want ) by clicking the message. Registration of the message service for a message looks like:
DATA: lr_service TYPE REF TO cl_bsp_wd_message_service.
lr_service = me->view_manager->get_message_service( ).
TRY.
  lr_service->subscribe_message(
                  iv_message_class = 'CRM_IC_PPL_UI_BDC'
                  iv_message_number = '114'
                  iv_subscriber = me
                  iv_activation = abap_true ).
  CATCH cx_bsp_wd_dupl_mess_subscr.
ENDTRY.
where is the ME self reference points to a view controller that implements the IF_BSP_WD_MESSAGE_HANDLER interface, including HANDLE_MESSAGE method.
