Dataport roleback error

Hi. I’m currently importing some items in 3.7b sql datase by a dataport It seems navision does not perform a currect roleback whenever an error occours. If i start with no items in my table after running ½ of the file and getting an error there are new tubles in my item record. This is not the way it’s supporsed to be according to every ACID proberties. I’m not using any commit() in my code Has anyone tried this and is there a solution? I would never like to make updates live anymore if this is a bug i 3.7b sql Kind regards Aas
