Hi Omkar,

Lookups used to access values in a back-end system when the mapping program is executed (runtime). By using a mapping lookup, a mapping program can call functions from other application systems while a mapping program is being executed.

please, have a look of RFC lookup step by step process. you will get clear idea about this.
