writeToMultiDataStoreEntity error in interface

Hi,


I'm new to appian. I created a simple employee onboarding form (1 wrapper interface contains 3 sub interfaces(personal details,address,bank).when i click submit all 3 tables in DB needs to be updated uing write to multi data store entity in interfaces itself(not using process models).


the problem i'm facing is once employee details submitted then we get primary key(emp id) this needs to updated in other 2 tables(address,bank) parallelly. i dont know how to configure the on success parameter for doing this.
