A batch is available for posting on the Post Journals form that has no debit or credit amounts shown for it. You post the batch and the Posting execution report contains the error 'No journal entry lines for this batch'. Now the batch is greyed out on the Post Journals form and I can not find it on the Enter Journals form. How can I find and delete this batch?

This batch does not have any journals. You need to use the Find Batches window to find the Batch on the Enter Journals form. From there, you can delete the batch. The first window that is displayed when you navigate to the Enter Journals form is the Find Journals window. You can not find the batch using this window, since there are no journals associated with the batch.
