Just noticed if you are really crazy and you attempt to import a Journal with a GLJrnGrp#GroupID that already exists you get an error that States “General Ledger Account Does not exist” Good to see an error, not so good to spend time chasing around looking for GL accounts that are clearly active. A bit of head scratching later. Alter the Group ID and it’s now working.
Please improve the errors? if possible or at least add it to a list of knowns that people can lookup.
