PP : Check logged-in user security roles

Product: Dynamics 365 CE, Model Driven Apps
Language: JavaScript

Doing an operation based on the logged-in user’s security roles is a common requirement is any Dynamics / PowerApps implementation. Here is a simple code, that you can re-use to do any activity based on user’s role.

For this example, I have taken a scenario of hiding / showing a tab in a form based on specific roles.

function showTabsByRole(executionContext)
{
   // Function to hide the  appointments tab by role
	"use strict";
    var formContext = executionContext.getFormContext();
	var roleCollection;
	var rolesVisibleFor = ["System Customiser", "System Administrator"];  // Replace this with the role you need
	var shouldBeVisible = false;
	var userSettings = Xrm.Utility.getGlobalContext().userSettings;
	if (userSettings.roles._collection != null)
	{
		roleCollection = userSettings.roles._collection;
	}
	else return;
	Object.values(roleCollection).forEach(function (obj)
	{
		rolesVisibleFor.forEach(function (item)
		{
			if (obj.name == item)
			{
				shouldBeVisible = true;
                formContext.ui.tabs.get("appointmentstab").setVisible(shouldBeVisible); 
				return;
			}
		});
	});
    formContext.ui.tabs.get("appointmentstab").setVisible(shouldBeVisible); 
}
