Flow control functions on interacting devices

The invention deals with a method for scheduling a plurality of functions (4, 5) provided on at least two interacting devices (2, 3) are executed, whereby first of the functions (4, 5) on a first of the devices (2, 3 ) and second functions (4, 5) on a second of the devices (2, 3) are implemented. The invention also relates to a system for carrying out the method with an administration unit (6, 7) a flow of functions (4, 5) so that they (the simultaneous passage of a first function (4, 5) and a second function 4, 5) that interfere with each other, avoid them.
