Hi @NurNina ,
Could you please share a bit more about your scenario?
Is there a column called "Customer Group" in your Products Entity?
I assume that the Customer Group is a Option Set type column in your Products Entity, and there is a available option for this field -- "Customer Price Class".
If you want to get the Sales Price value (Sum value) based on the specific Customer Group value (e.g. 'Customer Price Class'), please take a try with the following formula:
Sum(
Filter(
Products,
'Customer Group' = [@'Customer Group'].'Customer Price Class'
),
'Sales Price'
)
Note: The 'Sales Price' represents the Number type column in your Products Entity.
If you could provide more details about your scenario, we could provide a proper workaround for you.
Best regards,
