You should select this indicator if you want the system to check the purchase frequency from the order for the combination type "separate combination" during circulation planning. If the indicator is not selected, separate combination normally takes place for each schedule line in an order item (regardless of the purchase frequency in the schedule line). If the indicator is selected, the system checks whether the issues combined are ordered in the purchase frequency in the schedule line. This means that the system checks for each schedule line whether the purchase frequency includes the combination issue during circulation planning.
Example:
A weekly free sheet that appears on Sundays is to be combined with a daily newspaper. The system creates a mix type for subscriptions, in which the indicator is not selected if a combination takes place. This means that a separate combination can also take place for partial subscriptions. The weekly free sheet is, for example, also delivered to customers with Saturday subscriptions, since its purchase frequency is not checked. The system creates a mix type for retail, in which the indicator is selected if a combination takes place. This ensures that the combination does not take place for every schedule line but only for those whose purchase frequency "includes" Sundays. If a retailer is is to be supplied with the weekly free sheet, it is necessary to create a schedule line with the appropriate purchase frequency in the order.
