Synchronous request

Hello!

How I can send Synchronous request ?

For example when I cannot call another process until my first business process do not finish.

ClassMethod Main() {

 set sc = FirstProcess()

//Dont start until first process finish
set sc = SecondProcess() 

}

ClassMethod FirstProcess() {

Set sc = ##class(Ens.Director).CreateBusinessService("BusinessServiceName", .BService)

Set sc = BService.ProcessInput(BSRequest,.BSResponse)

}

ClassMethod SecondProcess() {

Set sc = ##class(Ens.Director).CreateBusinessService("BusinessServiceName", .BService)

Set sc = BService.ProcessInput(BSRequest,.BSResponse)

}
