|Resolution||This may be due to a lookup filter having been created that no longer has an existing relationship.
For example, a lookup filter had been created for the Service Contract Object, but Entitlements has since been disabled.
When you save the formula, we gather info on other formulas on the Object as well and this is why when you try to create a new one it will fail. You will need to deactivate the affected Lookup filter. In this example, re-enable Entitlements, disabled the Filter, and then disable Entitlements again.
