When using PVCS via SCC in SQL Navigator, after an upgrade to 6.7, it's not possible to check out objects from SQL Navigator. It did work in SQL Navigator 5.5.4.
The following error message shows in SQL Navigator:
'Error in SCC: PVCS Source Control (while attempting to get revision of file 'File_name' from project '/Project location'): SCC Error: Non-specific Error
WORKAROUND:
Please upgrade to use Serena PVCS client v8.4 to resolve the issue
STATUS:
Waiting for fix in a future release of SQL Navigator
