Your message is a bit unclear. At one point you call the tachess "yet to be retrieved" yet you say you "retrieved just prior to clearing the batch status report."

When you click on the Retrieve icon, do you see the applications listed from which you want to retrieve transactions? In the BR and AP, does "Print consolidate GL transactions" show the transactions you want to retrieve into Ledger?.

If so, you could do the following:

Move all the files starting with GL and ending with your three-character data extension from your Adagio data folder into a new/temporary folder (for safety). Then restore the GL files from your backup system to your data folder

If the batches have been retrieved into Ledger and not posted, and you are running the most current version, you could:

Export the batches to files. Proceed as above. Then import the batches from files you created.
