We are implementing EEC 6.0 to our client. Sales order comes from legacy system to sap. Pricing maintaing in SAP only. In legacy system they are having one field for discounts. Sometimes they will enter discount amount to the particular customers in that field. Some standard discounts are maintaining in SAP already, generally the standard discount condition types only will triggers in to the sales order.
Here the requirement is, if they enter discount amount in legacy system that amount should come into sales order and it should overwrite the standard discounts (SAP Discounts).
How we can configure this scenario,
Thanks in advance.
