To release a numbering scheme, open ProSite and navigate to the Settings Pane.
Select the 'Automated Numbering Scheme' tab and then click 'Load Numbering Schemes'.
To unlock the required numbering scheme, select the numbering scheme (the Cell will be BLUE or the arrow will be in the left hand column) and then click 'Unlock Numbering Scheme'.
The users will be warned that this may cause integrity issues, clicking OK will unlock the numbering scheme and allow it to be selected again for the next export to site.
