We have items with multiple UOM and each item will have different conversion factor. I created a material request with one item and saved it. The UOM conversion factor was showing correct. Then I changed the item to another item and saved the material request. UOM conversion factor is showing the old one only. It did not take the UOM conversion factor from the new item. Now client is cancelling all the documents till material request to do the transaction correctly. As there are batch involved, if we delivered the item, we wont be able to do anything. UOM conversion factor need some validation in different documents.
