Error during creation of SYNCBO

Hi

I am trying to create a SyncBO based on the tutorial from MDK for Smart Synchronization.when i enter the function module "MEREP_COUNTRY_GETLIST" in the GetList of the BAPI Wrapper and try to go to the Mapping Screen i am getting a error

"Default value for parameter SPRAS is of no effect at runtime"

What could be the problem?

Thanks and Regards
