Transaction launcher is not calling the BSP page

Hi! Experts,

I want to load a BSP application page on the on the Web UI using transaction launcher.

For this I have created a BSP Aplication and a URL using this bsp application name and page name.

While creating Transaction launcher I used this URL.

I assigned this transaction launcher id to a logical link and gave target ID as 'EXECLTX' , parameter class as 'CL_CRM_UI_LTX_NAVBAR_PARAM'.

I requested this logical link from a direct link assigned to my navigation profile but I am unable to load the page.

I tried to debug it, it was calling Transaction launcher handler class methods, but it is not entering the BSP application code at all..

If I directly call the BSP application page URL from browser then its loading fine but through transaction launcher it isnt opening.

Please suggest me what can be the possible error I am making.

Thanks and Regards.
