Can you explain a bit more "In my storage type 914 I have multiple bins"
I see that you listed 3 bins, but I think you gave us some fake names, didn't you?
Usually you just define in the movement whether you use dynamic bins which would then be the number of the process order or named bins which are fixed and always taken when this movement is used.
What are your bins there, is it dynamic or does it have some special meaning for you?
