Hi @MariBa,
Yes, you can definitely set this up in Adobe Campaign. The easiest way is to use the Split activity in your workflow. With it, you can break down your audience into the groups you want.
First, split your population into the two main groups (for the two different surveys).
Inside each group, you can then add more splits to divide by age ranges (so each age group gets about 1/3 of the records).
Then, within each of those, you can use another split or the sampling option to apply the service cabin percentages (Economy 60%, Premium 20%, Business 20%).
This way, you’re layering your splits:
1. Survey group →
2. Age group →
3. Cabin type.
It might look like a few splits nested one after another, but it will get you exactly the distribution you need.
Hope this helps!
Thanks,
