Hi Brian,
It seems that the particular database history is probably the most important to understand in order to fix this issue - I think we would like to take a look at the database while it's in this state in order to best determine what happened. Do you have a support plan with SAP and could you provide this database to us for further analysis in a support case?
If you don't have a support plan with SAP, could you contact myself directly ( firstname.lastname@sap.com ) so we could maybe arrange an exchange of information so we can hopefully still fix any outstanding software bugs that might be related to your issue?
Regards,
Jeff Albion
