Doing a course in Inventory Management will be more beneficial as you said you are working in a store dept. Supply Chain Management is the bigger domain which includes many sub domain like inventory management, provisioning, procurement, receipt, transportation e.t.c. It is a genuine advice that you work little bit on your grammar also to avoid mistake.
