HI @Amit Verma   thanks for your reply ,

I am implementing an asynchronous Ajax call on the "on change" event for Field A. This call retrieves a value for Field B and saves it. However, in the context of using Fields A and B in MVRS, if a user modifies Field A and immediately clicks the Add button, there may be an issue where Field B does not get saved due to the asynchronous nature of the call.

To address this, I intend to introduce a delay by displaying an alert. This delay allows the asynchronous Ajax call to complete before proceeding. However,  users do not want to click alert(OK)  manually. Instead, the delay should automatically take effect when the user clicks Add button.
