You must allow access to at least one attribute group while accesing EBS purchasing forms

Fresh Installation of R12 EBS Instance normally gives the below error message, We had the same issue in our freshly installed instanace and we solved it by licensing the Products from the below navigation.


Error = "You must allow access to at least one attribute group"

Login to EBS ==> Oracle Application Manager==>License Manager and License the Instance as per below screen shots.
