Maintaining Schema Registration
Whenever you add or delete a taxonomy in the xbrlfiles directory on the Reports Server, you must update your schema registration so that your instance document does not fail upon export.
To maintain schema registration:
After you add or delete a taxonomy in the xbrlfiles directory, log on to Reporting Studio.
Select File, then New, and then Report.
Select Task, then XBRL Management, and then Schema Manager. XBRL Manager - Manage Schemas is displayed.
Click Update Registration.
If you added a taxonomy to the xbrlfiles directory, the registration schemas are listed in Registrations to be Added.
If you deleted a taxonomy from the xbrlfiles directory, the registration schemas are listed in Registrations to be Deleted.
Click OK to update the registration of schemas.
