Question:

How to display My Accounts Buttons or Action Button drop-down in iRep?

Answer:

The Action Button only appears if the user has Create privileges on the Order_vod, Inventory_Monitoring_vod, or Sent_Email_vod objects. An action button appears on the right side of each account row that contains contextual actions. 

Without Create access to those objects, the default New Call, Launch Media, and View Hierarchy buttons appear. The buttons adjust the right edge of the account information boxes to the left, which may cause wrapping of the text.
