Channel and Category Margin Comparison

Meridian Retail Co. · SQL · intermediate

The brief

Nura wants to know if the margin problem is isolated to one channel or affecting all channels equally. Her hypothesis is the online channel was hit harder because that's where the discount code was applied. Can you show gross margin percentage by channel AND by category for the last 3 months? Flag anything below 20% — that's her minimum threshold.
