Not sure if you can do one just for journals. But this tool will let you split the TB by transaction type, etc so you can easily get a list of the JD's and JC's
Just extract and open the file. To locate the required "Setup.DTA file" you need to know the file path of the Sage ACCDATA folder as it is in there.
Then jut follow the steps including adding in the username and password for a Pivot table TB to be created in about 15 seconds.
If you are not familiar with manipulating the pivot table to get the info you need, just let me know and I will try to explain further.
BT. This file needs registering after one days use. It is a very useful tool and one I use on every client to check the VAT codes etc.
