RPA Express tool has the capacity to develop a project by writing groovy script or java or with the help of Action Control. Is there any difference? Is it like the things or the steps I am unable to do through the action control can be done with the help of Groovy script or Java? Or they have the same capacity?
You can use both options, but coding is more flexible in comparing to Actions Flows. You can use standard program language approaches, Simplified API within your own code.
The only limitation is that you cannot mix Actions and java code in Recorder perspective. If you need to add some Java or Groovy code, you need to use Custom Script Action.
If you need to write whole module in Java or Groovy, you need to use Code perspective and write your own code from the start till the end.
