Re: HP OVSD 4.5 Service Type and Table Linking Very Urgent help Please
Not that we don't want to help but I truly believe these questions could be answered by sitting down 10-15 mins. with your DBA and exploring the Service Desk tables.
If you're building reports, remember we suggested using the SD-generated Views for Reporting, which will make it a lot easier to identify data.
You may want to consider getting a sandbox server (if you don't have one already) with its own database that you have access to, so you can explore the database structures and easily communicate to your DBA when asked about Service Desk tables and referential constraints.
Having said that...
What's "Service Type"? Do you mean Service Level, Service Event or Service? Or is it a Custom Field present only in your installation?
