BETArchiveFirstGeneration & BETArchiveSecondGeneration

Hi community,

I'm working on a new view object to create custom dasboards for my customer based on Bulk Email stats. I noticed that Creatio has an OOTB View object called "VwBulkEmailAudience" which is based on "BulkEmailTarget", "BETArchiveFirstGeneration" and "BETArchiveSecondGeneration".

Does anybody knows what the least two tables are used for? I have checked both the local-dev and the production site, and those tables are empty.

I enclose the script for the OOTB View in case you'd like to gain a better understanding of what I'm talking about.

Thank you in advance guys and girls! Have a nice day :)
