FIX This JET SQL Syntax error
ALTER TABLE [tFIL@CTL] ADD COLUMN [LasttMVSKUUpdate] DATETIME NOT NULL DEFAULT #04-01-2021 00:00:00#;
This should NOT be a syntax error - and it is at present, solely because JET/Ace parser won't correctly parse the value of a DEFAULT constrain from within Access itself....but it might work if you do the very same command via an ADODB Command!?? What sense does this make??.
