hi ,
before query on scn, i already use this fun to initial pbt environment,but it will display error message : pbt environment already initial, and i only call it once, and this message is catched after i call arfc.
it's against the sap help portal(this function will auto call if you not call,if you manual call this fun,it will not auto call)....i guess maybe the reason is i call the function by dynamic. so now i dont know how to process it . the dynamic is user requested.
