There's a reconciled deposit that's displaying as not yet posted and when trying to post it to the General Ledger, it does not validate or post.
If the deposit is listed as Not Yet Posted, run a validation post report in Administration to see if it comes up to post. Not Yet Posted, Reconciled deposits can be posted even though they cannot be edited. This prevents reconciliation issues later on. If it does not display on the validation post, click Chat with Support for assistance.
