All brands are running promos on Shop in Shop (SIS) locations. These offers have various sharing and non-sharing agreements with the retailers and have a fixed period. Sometimes retailers extend the campaigns beyond suggested period or increase the percentage of discount.
When sales data is received it needs to be checked for discounted sales and active promos during the period and invalid discounts needs to be shown separately. For these discounts the brand will not reimburse the retailer. This is very essential and time-taking process for all brands and requires a lot of effort.
