Hi Bharath,
Yes, you can achieve the same via URL redirection. Please follow the below steps.
1.Create a service in SICF e.g. sap/bc/redirect_z3 in your SAP TM system and follow following steps.
2. Create a class with interface IF_HTTP_EXTENSION e.g. ZCL_REDIRECT_URL
3. Maintain class created in step 2 into the Handler List of the service created in step 1.
4. In class ZCL_REDIRECT_URL Method IF_HTTP_EXTENSION~HANDLE_REQUEST write below code
Data: lv_target type string.
lv_target = 'Z3://searchsmartstart.......'
server->response->redirect( url = lv_target ).
5. You can also read the parameter from the source URL with below program code
CALL METHOD server->request->get_form_data
EXPORTING
name = 'PAR1'
CHANGING
data = lv_par1.
6. Now attach the URL of your service created in step 1(Which will be http/https URL) to Attachments table in FWO / FRB application with parameter you want.
Now once you click this URL , Mehtod IF_HTTP_EXTENSION~HANDLE_REQUEST in Handler list class will execute here you can read the parameter as mentioned above and form a target URL and redirect to you intended target .
Thanks, Pravin
