Issues in generating PeopleSoft Compare report - System Error and SamDestroy codes

When running a compare report between a database and a Maintenance Pack file, the PS Admin had to face the below error message. This error would not allow generating the compare reports any further.


Records Application Upgrade Compare ended:  2011-09-08-00.33.44 (62,21)
Records Compare Report Created : c:\----\Upg00Records.prt

SamDestroy 0: 3191 vs 0


Solution: 
We had the PS Admin to do the below changes to get this issue resolved.

1. In compare report window, UNCHECKED the ''Update Project Item/Child Status'' option.
2. In Configuration Manager - CHECKED the ''Disable DB Stats'' box. Alternatively one could collect the Database Stats while still having the ''Disable DB Stats'' box unchecked.

In a different database, PS Admin for a project encountered a little different issue. Below was the message PS Admin would face. However, the resolution is same as the above.
