Problem
The batch has been successfully exported, but you still have the option to post.
Solution
This issue occurs when you unpost a partially exported batch and unbatch the items that are not exported, leaving only the exported items in the batch.
To resolve this issue, check first that your transactions have exported successfully in your accounting software. Then post and export the batch one more time to mark it as successfully exported.
If you are still seeing the option to post, bypass the batch to clear it out of the queue.
