When you are using GOS toolbox menu in some transactions the Attachment list service is active, but when you opened it there are no attachments in it. Previously this was the designed behavior when the application published GOS with more than one business object. Recently an enhancement was released in SAP note 1966453 in order to give the control to the customers to decide:
have a consistent behavior of the active / inactive status of the Attachment list, so when no attachment exists make the service always inactive or as usual active when there is least one attachment in it, but in this case some delays may occur when the GOS toolbox menu is opened
OR
have the standard behavior, so when the application publishes GOS with more then one business object the Attachment list stays always active and in this case no performance problems can happen
