What is an "orphaned" block, how to the happen and how to I fix them?
Generally speaking, orphans occur when we attempt to lookup information about a block from the database and the information cannot be found.
This can occur for several reasons:
- The project has been moved without using the Packup/Unpack process.
- The data was deleted from the database.
- Multiple instances of the requested data are found. This can be the result of duplicate entries in the database.
- In the case of a SysName lookup the SysName and Location fields are not found to match.
