Hi JoanEllen
Sorry I am not a MYOB employee, just a forum user like yourself - trying to help.
I note from your screenshot you seem to be using the Server Edition (see Help > About AccountRight to confirm).
Using the server edition seems to have its own issues. If you are the only user, consider using the normal desktop version.
The main difference between the 2 is the normal desktop version uses your Documents/MYOB/My AccountRight Files folder for your Library, the Server edition uses the Public Documents/MYOB/My AccountRight Files folder for your Library folder as it is a shared location. The Server Edition also allows you to change the location of your Library.
If you have modified the default library location using the Server Edition, I have heard of a problem during a version update where MYOB would switch you back to the default library location. Because the user left a copy of their file in that original location and did not rename it, after the upgrade the user opened the file from the original default location, not realising he was opening up an old copy of the file. Transacitons were missing, reconciliaitons were not up to date etc. Not sure if this is what is happening in your case.
In your other posts, you also wrote:
I found out today that after our datafile had upgraded, MYOB creates a duplicate copy of the old datafile in the same area in MyLibrary
What is meant to happen is MYOB makes a copy of your file before upgrade. If your file is called MyCompanyFile.myox, MYOB always renames this as MyCompanyFile (Old v2023.1).myox and the upgraded file is called MyCompanyFile.myox. This is a precaution in case the upgrade corrupts your file - you do not and should not open that precautionary copy.
MYOB cannot produce a file from the previous day, not unless you have this saved somewhere.
Just a suggestion, do a search on your computer for every file called Just Cleaning (Queensland) Pty. Ltd. ATF.myox - if there are more than one - rename those extra copies to avoid using them. Do same with other file. You should only ever have one file with that filename.
Also review your procedure and ensure you understand backup and restore. I once had a client who did not understand how MYOB worked. At the end of each day he would create a backup. First thing the next day he would restore that backup and use it, thinking this is what he had to do. Restoring backups should only be done for specific purposes and these should always be identified by that purpose in their filename.
