Message Mapping Scenario- Field Mapping with list of values

Hi All,

I have requirement in message mapping. I need to map the value dynamically based on following. for example

EN -> ENGLISH

JP -> JAPANESE

ZH -> CHINESE

FR -> FRENCH

What is the correct technical approach resolve the above mentioned scenario? can we store it anywhere in CPI? Currently We plan to use script with switch case. Is there any other option available in SCPI(HCI).

Please help. Share any links which could address the above mentioned problem.

Thanks in Advance
