Hello Vinay, it looks like you’ve correctly found the source of the problem. The issue is that the specific workflow running your chatbot, the Process Model, needs its own separate permission to save information. Even though you assigned the bot and the application, the process itself is being blocked from writing to the data table.
To fix this, you just need to update the security settings you showed in your screenshot. Go to the ‘Process Assignments’ section and add your chatbot’s process model to the list. Be sure to give it ‘Editor’ or ‘Administrator’ rights so it can save the new data. That should resolve the issue for you.
