Error getting while importing CRM 2011 solution: Error getting in entity opportunity in system views

You are attempting to update in the active context when there exists an active row, but either the active row has a state other than publish or unpublish or you are attempting to do a published update of a publishable component, which is not allowed.  _Input.IsBeingPublished: False; CurrentState: Microsoft.Crm.Platform.SolutionAwareComponents.BusinessComponentState.

Can anyone help me in this?
