I got a tip from @Skye Hansen‚ that might help you. Skye suggested doing a count using LEN( and then subtract the number of characters in the job number, providing it's consistent, and display the rest. Something like RIGHT(Name,(LEN(Name)-11) . That's if there are 11 characters in the job number.
If you had a consistent character in the job number, you could use another method I got from @Teale McCleaf‚.
That is to use the special character as a delimiter like in an email address. LEFT({emailAddr},SEARCH("@",{emailAddr})). this pulls the LDAP name of the user separate from the domain name.
Hope this helps.
