See Using Wildcards which can be used in name mappings.
The parent object i.e. the browser should be defined as http://pega-*app-02.inside note the wildcard * being used. All your other child objects will be beneath this. Therefore, there's no need to define the name mappings twice, for each environment.
I have tried to pass the main URL as a variable as an attached screen. but it was not recognized the INT environment's element when executing on INT environment (pass INT URL while executing on INT for variable value)
Your ObjectType URL is referring to,
How will that work, for the INT environment!?
Sorry for the confusion. What I meant was that when I was running on the INT environment, I passed the INT URL as a variable (for the highlighted URL). The screenshot I have attached is not relevant to the sample project; I just wanted to highlight the URL variable that I passed there.
That screen was relevant to the UAT environment and it was working well. but when I tried to execute the same script on INT by passing the INT URL it was not working (unable to locate elements, but the same locators are there).
"I passed the INT URL as a variable" - what do you mean by this exactly?
