Error While Activating Attribute View

Hello Experts,

I am trying to Save and Activate my simple attribute view but getting below error. Looks to be an privilege issue but not sure how to resolve it.

Message :

Activation ID: XXXXX (Repository: User is not authorized to execute specified operation;User 'XXXXXXXX' has no authorization, privilege: 'REPO.MODIFY_CHANGE'!)

I have masked the Activation Id and User name with "X".

Can someone help me on this?

Regards
