Can we set a custom field as mandatory based on other custom field value in same transition screen ?

Question

We have configured a transition Namely "Detail Analysis Completed". In this Transition there is 2 fields -

1) Global in nature?  [ Field Value = 11425 ]

2) Target Project Name(s) [ Field value = 11426 ]

In "Global in nature?" field there is 2 values -

1) Y [ valueid = 11588 ]

2) N [ Value ID = 11589 ]

Now we Need to set "Target Project Name(s)" field as mandatory when "Global in nature?" field value is "Y". Please note both "Global in nature?" and "Target Project Name(s)" are in same transition screen. Do we need to set any post function/condition/validator for that? If yes, then could you please provide us steps ?

Thanks in advance

I am not understand how can we implement this. Previously we have succuessfully impleamented "Show a particular customfield based on another customfield value" by configuring customised plugin using js script. Please find the js script below for previous case -

jQuery(document).ready(function($) {
JIRA.bind(JIRA.Events.NEW_CONTENT_ADDED, function (e, context) {
    callChangeFunction();
});
callChangeFunction();
function  callChangeFunction(){
        showHidField();
        // dropdown custom field change function
    $("#customfield_10020").change(function() {
        showHidField();
    });

}
    function showHidField(){
        //drop down field selected value
        var dropDownFieldval =
        $.trim($("#customfield_10020 :selected").text());
            //test field1
            $("#customfield_10221").closest('div.field-group').hide();
        if(dropDownFieldval == 'New Machine Required'){
            $("#customfield_10221").closest('div.field-group').show();
        }

}
});

Can we using same procedure for "set a customfield required based on another customfield value" ? If so then could you please provide us the steps?

There may be other ways to do this, but one way is using a validator. Specifically, Conditioned validator that will return to the user if the condition is not met for them to do whatever is needed to allow the transition to proceed, like updating issue fields either from the transition screen or elsewhere. You use Substitution variables to retrieve the transition variables (in your case) to condition and also to construct a nice error message for the user.
