I have two different orders for 2 different order types, both for MTO material. These are dummy materials which needs to be replaced when actual material is ready to deliver. Now i want to change the dummymaterials in both the sales order.
In one order Requirement type is getting determined as KEV (req class=045) and in other requirement type is getting detrmined as YUK (req class = YUK).
Now the KEV order allows me to change the material but order with YUK item category doesnt allow me to change the material in sales order.
Can you suggest me what could be the possible reason for this?
