RE: Smartlist in GP 18.4.1384 - Unable to see new transaction user defines
Hi Kanti,
I have not personally seen this issue, but here would be 2 things that I would try.
1. If you have SmartList Builder installed, try temporarily disabling it under Customization Status.
(Microsoft Dynamics GP >> Tools >> Customize >> Customization Status).
After you disable this, keep GP open but make sure that you close and reopen the SmartList window inside of GP. See if there are now 2 Account Transactions folders (one is our default and the other is a SmartList Builder replica) and verify that the column is not available under both. If it is missing from one but not the other then you most likely have a SmartList Builder copy saved over the top of our default that is missing the column.
2. The other thing that you could try when all users are out of the system is making a backup of their DYNAMICS and Company databases and then reinitialize the Account Transactions View.
(Administration >> Setup >> System >> SmartList Options)
Select Account Transactions, and View.
Then Click Default to reinitialize the columns available for selecting.
If you do not get desired results you would need to restore from your backups.

I hope this helps!
