In your specific case, Data is the CC numbers you are targeting, 47 and 50 in this instance. The column to the right is the value your are sending for the given CC number.
So in your image, CC47 with a value of 0 would mean you are loading performance number 1 in your KPA. And if I am not mistaking, sending CC50 with a non zero value means your are loading slot 1 in your target performance. Slots 1-5 are loaded with CCs 50, 51, 52, 53 and 54 respectively.
