The error points to existence of non-structural indexes on the table and you are trying to delett the structural indexes.

>The method I'm dealing with starts with a call to a save function that starts and ends a transaction. When the BEGIN TRANSACTION is issued in the save I get an error:
>
>Error 1548: Table myview has one or more non-structural indexes open. Please close them and retry the Begin Transaction.

>So... ok, I'll get rid of the tags before calling the save, like so:
>SELECT ( tcView )
>IF !EMPTY( TAG( 1 ) )
> lcSafety = SET( 'safety' )
> SET SAFETY OFF
> DELETE TAG ALL
> SET SAFETY &lcSafety
>ENDIF

>Which, surprise, nets me this error:
>
>Error 26: Table has no index order set. (on my DELETE TAG ALL line)

>Next logical step would be to set an order then. "SET ORDER TO 1" gets placed prior to the DELETE TAG ALL. Running this nets the same error in the same place.
