Btrieve tried to perform a Begin Transaction operation without configuring Btrieve to allow transactions. Ensure that the Btrieve Record Manager is configured to allow transactions.
Note that the Xfh2btr module will attempt to start a transaction on the first updating operation (REWRITE, WRITE, DELETE) after a file (with the WITH ROLLBACK clause specified in the SELECT statement) has been opened or after a COMMIT or ROLLBACK statement has been processed.
