Activity pricing based on Date

Hi,

We have a requirement from Client to Pick activity pricing from KP26 based on Date

For example, Service order is created with two operations such as Travel and Boarding

we have created two activity types A1110 and A2110 respectively

and Activity pricing is maintained in KP26 for both based on number of Hours . Now client requirement is if same activity A1110 triggers on 4th April for 1 hour cost should be 100 and it triggers on 5th April cost should be 200

I tried with different layouts in KP26, but not able to get anything specific to Date

Could you please throw some light on this functionality, whether this can be accomplished using KP26 or any other functionality

regards,

santosh
