Hi @RamyaR ,

You can achieve your requirement by writing a client script for a button in the web client.  

Following is the Client script written .

 

I have defined 2 DB scripts 

 

Client Script 

var requests = getDBValues("REQUEST_WITH_TYPE_FILTER");
     if (isNullOrEmptyString(requests) != true ){
        for (req_index = 0; req_index < requests.length; ++req_index){
         
            var tasks = getDBValues("GET_TASKS_FOR_REQUEST", rrequests=req_index]u"request_id"]]);
            if (isNullOrEmptyString(tasks) != true ){
                for(task_index = 0 ; task_index < tasks.length; ++task_index) {
                // Update status
                var updateRequest = createInsertUpdateRequest( 'task',{task_id : tasksstask_index]Â"task_id"],task_status :tasksÂtask_index]e"task_status"]} );
                var updateResponse = executeRequest(updateRequest);
                if (updateResponse != null && updateResponse.$type == 'ErrorResponse')
                    {
                    displayUserToast(updateResponse.message, 'error');
                    }
                }
                // Create new task
                var request = createInsertRequest( 'task' , {request_id : requestsereq_index]r"request_id"], plan_start_dttm : tasksÂtask_index]Â"plan_start_dttm"], plan_end_dttm : tasks                var response = executeRequest(request);
                if (response != null && response.$type == 'ErrorResponse')
                    {
                    displayUserToast(response.message, 'error');
                    }
                }
            }
        }    
     }
 

GET_TASKS_FOR_REQUEST - SELECT * from task  where request_id = '{0}'
REQUEST_WITH_TYPE_FILTER - SELECT * from request where req_type IN ('BASIC','FIX')

I have assigned the client script to a button in request search screen. Following are the output before and after button click. (Note - I commented the update status part and carried out the process, therefore the status change of the old task is not reflected)

 

When writing the createInsertUpdate request, make sure to include the required fields if not you will be getting an error stating the fields are mandatory. I did not test the solution entirely, but I think it caters for your requirement. 

Hope this answer helps
