Running an SAP transaction in a new session (new SAPGUI window).

Function ABAP4_CALL_TRANSACTION will attempt to start an SAP transaction in a new window. It will work only if the maximum number of user sessions is not reached yet. The call should be done with addition “STARTING NEW TASK” and  DESTINATION ‘NONE’. You can check the number of currently open sessions/windows before with the function TH_USER_INFO.
