Trigger Re-pricing on Value Change

Hi,

In SPRO - CRM - Master Data - Products - Special Settings for Sales Operations - Define Product Groups I am using Product Group 5 where I need to trigger re-pricing on a change of one of the values configured in here.

I have looked at the BAdI CRM_PRICING_BADI but this does not look like the appropriate one. Does anyone know if it is possible to trigger re-pricing on an item in the sales order when the product group 5 value is changed using a BAdI and which BAdI this would be?

Many Thanks

David
