Value Help is not getting validated with keystroke TAB in SAP IRPA Desktop Studio

I am trying to automate a Maintenance Notification Screen in SAP Fiori. While doing so I am reading data from an excel file and trying to set the value in UI of Maintenance Notification screen.

The first Control on the Fiori Screen is a Input Value Help. As I used Set activity to set the data. The Data is not getting validated and hence Eventually when I am trying to click on Submit button. The Submit action is not getting triggered.

Can you please suggest what action I can use for this in Desktop Studio to achieve this action.
