Stock bin location change

SUGGESTED

Why do I get this when trying to change bin location for a product ? "Line number 1 : Incomplete Line:
No entered stock transactions / Dock type location prohibited" Just trying to clean up the warehouse and get product in the right location so it is easier to pick jobs. The method I use, stock change--destination to destination, works half the time then the other half it gives me this error. WHY?!?!
