Update fails

Delphi 10.1 Berlin
MSSQL 2012
ADO

I am stumped as to why this update fails. The reconcile dialog returns the following:

Maybe this means more to you?

After several hours of dinking around, and I don’t understand why, I have found that the time portion of the date/time is making the updates fail

The Last Record fails to update as shown at the bottom of the above snip.

Can you shed some light on why that may be? I see no reason for this.

it depends on your application.
is DueDate field is part PK?
according to your application logic, this field can have time part of not? if not, you can strip time part on client-side.
is specific BusinessProcessor used for this table? if yes, what UpdateMode it has?

can you create a simple testcase, that reproduces this case, pls?
you can attach it here or send directly to support@
