What is the meaning of error - "Column data is unavailable"?

[Tony Z]

I ported my .mdb project to .adp, but now I get that message when I try to
save a record from a form. Anyone know the cause?

[data unavailable counter problem?@discussions.microsoft.com Column data unavailable counter problem?]

After all I believe to have found the error's cause. Removing a counter from
the crashing form (a normal textbox with control element "=Count([ID])")
solved the problem - no crashes anymore and no error message "column data is
unavailable".

I am also having this problem

We began receiving this error after converting our Access 2003 project using a
SQL Server backend, to Access 2007. The message "Column data
unavailable" comes up on GotFocus of combo boxes where we normally assign
the rowsource based on other entered data. This never happened in Access 2003
but is happening quite often in Access 2007. The first time it happened the
rowsource was actually based on values from a query from a linked server so I
changed it to create a temporary table instead. Now the message is coming up
for
a combo box that is queried straight from the SQL Server data.

Please, any help on this would be appreciated.
