Calculate phase currents when line currents are known in delta configuration

Say let us have a delta connected source and star(wye) load. Let the system be either unbalanced or balanced. Suppose we know the line current in the system. My doubt is how to calculate the current in each phase of the delta connected source.(We know to calculate line current when phase currents are known using KCL) I doubt there are infinte solutions for the phase currents for a particular set of line currents. Please anyone enlighten me.
Thanks in advance.
