How can I map a custom field name (e.g. "TestCaseID") to the customfield_12345 name without coding

[Mark Mayotte]

Errors on custom fields in the logfile refers to the "customfield_12345" tag... is there a way, in the Jira application, to find the mapping to the field name?

Go to Admin > Custom fields. Click the three dots to the far right of one of the fields and select Configure. Then in the address bar of the browser, change out the number for the one you are searching for and hit enter.
