Service Layer SBOBobService_SetCurrencyRate not found

Hello everyone

I was working on a scenario which calls SBO Script SBOBobService_SetCurrencyRate.

After many failed attempts I tried to use service through Postman.

GetSystemCurrency,GetCurrencyRate etc are working fine.

But SBOBobService_SetCurrencyRate is returning 204 No Content response.

I'm working on Integration Framework 2.0.

Any kind of help will be appreciated.

Thank you
