Simulate data with SAP Bydesign

Hi Experts,

As I know SAP Bydesign has some standard web-service to do the data migration, some of them has the simulation function named example "Check account". But what if I want to use SDK for simulating the data before save it to database ? Because some standard web services do not have the simulation function so I want to know if there are some functions I can use to simulate data.

Thanks and Best Regard
