You can set up local error handler to intercept error 1707. If your table has a primary key see Message #538390.

lcSaveOnError = ON("ERROR")
ON ERROR DO LocalOnError WITH ERROR()
USE test EXCL
ON ERROR &lcSaveOnError
...
RETURN 
*-----------------------------------------

Procedur LocalOnError
Lparameters tnError
IF tnError = 1707
	* CDX is missing
	RETRY
ELSE
	* Something else is wrong
	* Invoke regular error handler
ENDIF	
RETURN
