Glad to hear you've got the transactions in now. Hopefully the hurdle has been surpassed and this will work from now on.

Something had occurred that prevented the process from working correctly for you. With these versions, I am able to post AP batches and immediately retrieve them into TB without locking messages, so there is more to this than just posting batches and retrieving.

The APTBBTCH file is the file that AP writes to when batches are posted, and TB uses to retrieve from to create the Disbursement batch. If the file was not locked on the server, then perhaps the ezsemtab or eztasks files contained invalid information, as Michael indicated. None of these 3 scenarios would be solved by rebooting a workstation.
