Database Transaction In SAP

Hi,

Does SAP support database transations, what I am doing is getting the values from one Zdatabase table , and taking a value which holds the total, adding one to this , and placing the record in a differnt ztable, and then incrementing the 'total' value in the orginal; ztable , I obviously want to make sure the whole transaction occurs or nothing, I'm using insert , update in opensql.

Thanks
