The following was emailed to us by a HelpMaster Pro user
If a user deletes an issue type from problem tree in Helpmaster Pro v7.5.184, do the jobs already closed with that issue type retain that issue? If not what does it change too?
Yes, the jobs retain the issue.
Whenever a job, client, asset, site or anything else in HelpMaster Pro links to a system code, and that system code is then deleted, the entity that was linking to it will still point to that system code. Behind the scenes, the system code is only marked as deleted - it isn't actually completely deleted from the database. This means that the system code will not appear in any of the drop-down boxes, or the problem hierarchy tree, so it can't be used again for new entities.
However, any existing entities that are linked to it will display the code when they are viewed.
There is an exception to this rule. If the system code has never been linked to anything, then it will be permanently deleted from the database.
