>Check sp_depends system stored procedure to find out where this field is used.

This:

EXEC sp_depends @objname = N'MyTable.HomePhone'

gives:

"Msg 15009, Level 16, State 1, Procedure sp_depends, Line 25
The object 'MyTable.HomePhone' does not exist in database 'MyDatabase' or is invalid for this operation."

The field does exist. So, it would then be related to the other side of the sentence in regards to being invalid for this operation.

Any idea on what I get this reaction?
