RE: Inquiry error message missing table SY01407.
The SY01407 table is the System Windows Defaults table, so, the first question is whether this table exists or not?
You can verify by running this script against your GP system database:
Select * from SY01407
From what I can tell, this table was added when upgrading to Dynamics GP 18.4, as I don't see it on my GP 18.3 environment.
If it doesn't exist in the GP system database, open a support case and we can verify that table, along with the indexes and dex procedures for it are created.
Then, after adding this new table and a backup of the GP system database, have users verify whether they still get this error message or not when opening the inquiry screen.
Thanks
