I finally found that COMCodeBook has a method in the aparameters.prg for each table. This is where you set the flag.

***********************************************************************************
Define CLASS UserADOComponentsParameter AS IADOComponentsParameter
***********************************************************************************
	Name        = "UserADOComponentsParameter"
	lEnableServerAssignedKeys 	= .F.
	nLockType   				= 4
	nCursorType 				= 1
Enddefine

Maybe this post will help others.
