operation not applicable

Can anyone give me more information on a database error "Operation not applicable"
I think in my case it has something to do with trying to search a table dataset that is in cached update mode.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Please Give information on
1. What Version of BDE
2. What Version of Delphi are you using
3. Type of search FindKey, Locate etc...


Although the user guide do not talks about this, one cannot use CachedUpdates with tables does not having Index fields. So

1 - Either Restructre your table from DBDesktop to give it an index or
2 - In you code, before doing any modification or search set Table1.CachedUpdates := false
