We have a flexible agreement with our supplier. It allows us to negotiate time to resolution for each issue separately. Initially it relies on issue priority (4 hours for Highest, 8 hours for High, etc.) but in some cases, when issue requires more work, we agree to get some more time to our supplier. This time is entered in a custom field (e.g. "150" means 150 hours) and there is no possibility to have dictionary in the field.
How to setup SLA in this case?
We tried to enter many JQLs in SLA goal, but it's not solution to enter c.a. 2000 entries (longest time we currently have in our database is 60 days (1440 hours).
Any idea?
