Changs Dates In PR which are created by the MRP

MRP sets delivery dates on the purchase requisitions based on the requirements and system lead times. Some of the vendors have a set delivery schedule for the products i.e. deliveries are made every Thursday and only on Thursdays. When POu2019s are created, the Buyer has to manually change the delivery dates. This manual process is a barrier to Purchasing Auto-PO initiative and leaves us open to operator error with the potential of affecting the companyu2019s on-time-delivery goal. Furthermore, multiple purchase orders can be placed with a vendor in a given month and they are not consolidated, which increases the transportation costs. In addition, some products are seasonal and can only be purchased during a set time frame within a year.

And i don't want to changes in The standard MRP screen, so any suggestion except this.

Thanks and Regards
