Mapping PersistanceID

Hello,

I'm currently reviewing the business_journal and business_data instances. I have a question about the PERSISTANCEID. I have created a bdm which is stored in the business_data database. Each class created has a persistanceID. Now, I'm trying to find the mapping in the business_journal database from the persistanceID to the process InstanceID.

I have a value of 1 in the business_data DB and within the business_journal I can't find which process this data goes to.

Do I have to add the processID to my model?

Thank you
