Greetings, lakefrontbelt.
Let me share information when running the Condense Data Utility in QuickBooks Desktop.
Please be informed that we're unable to edit a condensed Journal Entry. For us to acquire those entries and add classes, we've got two options for this.
We can restore a backup company file or create a new company. Once done, we can manually transfer the transactions including your JE's to add the classes.
