We are trying to activate the session tdsls4242s000 from the sales order lines tdsls4102s000 zoom menu.

stpapi.handle.subproc("tdsls4102s000","tdsls4242s000","add")
stpapi.handle.subproc("tdsls4102s000", "mtdsls000090171", "5")
stpapi.zoom.option( "tdsls4102s000",5,"tdsls4242s000",error.code)

But still the session is not activated from tdsls4102s000.
Kindly help urgently......

Is tdsls4242s000 on the special menu for tdsls4102s000? If the answer is yes then this code is all you really need"

stpapi.handle.subproc("tdsls4102s000","tdsls4242s000","add")
stpapi.zoom.option( "tdsls4102s000",1,"tdsls4242s000",error.code)

Notice I put 1 in the stpapi.zoom - assuming the zoom takes place on form 1. Of course we do not use the sessions so I do not know the correct form number.
