Quick Link
eTAS sends you a mail when a new user was entered via the european infobase. In this mail you will find an link as you can see in figure 1, witch allows you to fill in the additional info like social security number easily. Check also if the headcount is correct (per default during import internal have 1,00, external have 0,00).
After you have clicked on the link you will see the form as shown in figure 2. Here you can add social security number, birthday, band, grade, family and specify the employee type. When you have filled in the data click on the save button to save the data in the hr-module. After saving you can close the page or you can use the link on the bottom which forwards you to the eTAS login page.
