How do I change or extend price derivations?

Hotel-Spider offers the option of deriving prices from product 'A' to another product 'B' and then applying surcharges or discounts to them. Multiple derivations are also permitted. The price derivation takes place in the Hotel-Spider extranet under 'Configuration' -> 'Products':

The surcharges and discounts later appear in the price calendar with the applied calculation:

Important: The surcharges and discounts can only be set for a maximum of 2 years. This means that the entries must be extended regularly!

To enter the surcharges or discounts, click on the 'Adjustments' tab in the derived product and then on 'Edit period':

In the window that opens, select:

1. the desired period or "All periods"

2. the desired surcharge/discount in % or €/CHF

3. whether the same surcharge/discount should also apply to other products

-> And hit 'Save'! 😊️
