User Role for Updating Data Groups in BIG-IP LTM??

Hi Neil

There is no role dedicated to Data Groups objects.

the best option available to you is iRule Manager role.

iRule Manager:: * can manage DATA GROUPS along with creating, editing and managing iRules * have read access all other objects * can limit access to specific partitions
