Input --> tFlowToIterate -iterate-> tLoop -iterate-> tFixedFlowInput --> output. Use the available_copies value as the To variable in tLoop.
Hey, is it possible that you explain it in more detail? What settings do i have to do in the components? in tflowToIterate i used the available_copies as key_value in tLoop i used the variable from tflowToIterate for my to value ((Integer)globalMap.get("avail_copies")) but i don't know what i have to setup in tfixedFlowInput (makes no sense to me)
