Error: invalid field value. Invalid code table entry: Journal occurs when importing transactions.
Check the spelling of all rows in column for the journal field. Remove any unnecessary spaces.
If using the downloaded import template from How to Import Journal Entry Transactions ensure the entries in the Journal column matches exactly one of the options listed in the drop down menu of the Journal field in the batch. Our import template has an example entry of JE which is not present in this drop down and will cause this error.
