Subject: We have a requirement to create a popup when user logins to servicenow which mentions the last login of the user.
Description: I have a requirement to create a popup after the user logins to instance.
What we tried:
1. we created an UI page and tried to call that Ui page from UI script by GlidDialWindow and its not working as popup of UI pages will not shown as the user will face workspace once he logins.
2.we have a Service operation workspace which is the landing page for all the users
we tried to change the welcome note dynamically to mention the users last login in the greetings of the heading of the Workspace.
But we are not able to fetch the last login value there as we can fetch only users first name last name country location fields only.
as attached in the screenshot below. |
