environment variables

Good Day all .
New wM/Sapbc developer here. I know of a few std webMethods environment variables, ie $tid, $iteration etc. Where can i get a list
of them so i know what is available within to me within a flow.

thanks
Chuck

Chuck,

What type of list are you expecting…Did you checked SAPAdapter userguide SAP services for default variables like $tid,$params …$iteration is a Loop step variable in the flow not related to SAP side.
