Build the calculation dataset

Confirm Fulfillment cost share with the store operator before calculation. Record the owner responsible for fulfillment cost share. Independently establish Fulfillment cost share, then compare it with Payment fee share.
The inclusion rule for Payment fee share should be written beside the form. Confirm the sign assigned to payment fee share. When Payment fee share uses another definition, place Return cost share in a parallel run.
