Hi Georgy Thank you for your query. The exercise system has around 23000 customers that you can use to simulate different kinds of dummy use cases. If you have a more generic question on customer information is mapped to Pega Marketing, then may I suggest that you please post the question on the Decisioning and Marketing space on Pega Mesh as this is not directly related to this Pega Academy course. Regards Guru

Hi  deshg ,

I would like to create one database table to insert customer data and it should appear as main population for my segment. As I have a different customer data requirement  than the sample customer data .Could you please help me in this regard.

Hi Vishnu It's good to see that you are interested in a topic that is beyond 'essentials'. This topic will be covered in a soon to be published course called 'Pega Marketing Implementation'. However, for now, may I request you to post this query on Pega Mesh on the Decisioning and Marketing space. I'm sure someone in the community (including yours truly) will be happy to help you. I hope you appreciate that we reserve this space for queries that are in within the scope of this course. Regards Guru
