Jim,

The above is not correct. It is not necessary to use buffering for transactions, it is necessary that the tables involved reside in a VFP database.

I would also advise that with two different databases that each one have its own transaction, so that the psuedo code would be;

BEGIN TRANSACTION
   Post to database A
   IF No Error
     BEGIN TRANSACTION
       Post to database B
       IF No Error
         * End 2nd txn
         ENDTRANSACTION
         * End 1st Txn
         ENDTRANSACTION
       ELSE
         * Rollback 2nd txn
         ROLLBACK
         * Rollback 1st Txn
         ROLLBACK
       ENDIF
   ELSE
     * Rollback 1st txn
     ROLLBACK
  ENDIF
