All our parts are externaly procured. None of our parts have data in the total replenishment lead time field. We have the lead time set in the planned delivery time field on the MRP2 screen. I changed yesterday the total replenishment time fort MATERIAL from 0 to 28 and then to 42 in order to check if that was the reason for V_V2 and the batch job not running ATP on this part. But it did not have any effect. Something in the ATP has been changed as we never had this issue before. .
