Not sure what you mean? A few of our tables had a TimeStamp field that had a Default value of Now(). When we migrated the tables to SP lists, the lists columns kept their default settings but if you appended a record with an Insert SQL statement, the TimeStamp field would stay Null. However, adding a record in datasheet view or with a QueryDef would set it properly.
Easy fix but when I saw Crystal's reply, I wondered if Access would allow a Table Macro on a linked SP list. It will not; all the Ribbon options are greyed out.
SP sucks as a BE but it is better than what we had. We are requesting SQL/Azure SQL Server but even though our client is rich (thank you taxpayers!), these things take time. It doesn't help that every time they hear the word "Access" they make the sign of the cross and slowly back away from me...
