I would like to remove the package and miscellaneous in the dropdown list of work item types in the timesheet. In version 6.0..it is using TMG - Work Item Types validation and i think it changed in PPM7.1 SP5 to higher SP version. Any idea how to remove these? I can't find the correct validation. Do I need to modify jsps?
I happen to still have the TM config guide for 7.1, there is a screenshot of the policy settings and the tab with the allowed work item types is missing there. Must have been added in a later version. If the validation in 7.1 is read-only too, you could set the ENABLED_FLAG in knta_lookups for one of the item types to 'N', empty caches on the server and then see if it makes any difference.
Then it looks like it was never meant to be editable. Are you planning an upgrade soon? Problem would be solved then. Plan B would be to change JSPs. But if you can avoid that, you always should. I cannot help you to find the right JSPs though, because I don't have an 7.1 instance and these pages certainly have changed since then.
