Hi Syed,

You can achieve your requirement as below

• Identify the event handler method associated with the standard table's cell ( the link )
• Enahnce the view and use POST_EXIT of eventhandler method of that link

               Please refer the below link for enhancements of standard component ( refer step 12 )

• Now, you will be able to get the processing row of that link and call t-code in that event handler method and pass the url parameters

          Please refer the below link

  Hope this helps you.

Hi Syed,

You will just pass the key information via URL parameters to your custom web dynpro application. I think for your requirement you no need to create t-code, you launch the url directly.

Please refer the below links

Calling one webdynpro application from another | Webdynpro ABAP

The above links clearly explains how to call one web application in other component and pass the url parameters.

Process can be divided as below:

•   Enhance the standard component, use POST EXIT and call the URL of Zcomponent and pass the parameters
• Go to eventhandler method "HANDLEDEFAULT" of window of zcomponent and read the url parameters
• Now, Based on the above parameters, you can populate the data into alv table in custom component
• Also, make the alv as read only by using method if_salv_wd_table_settings~SET_READ_ONLY( abap_true)

Hope this helps you.

Regards,

Rama
