Hello, 

How work with EIN then I use variant in Release Engineer. Then I create EIN for the Variant and change the variant to another one to also give it an EIN, but it already had a number assigned to it, the same as for the first variant. In short, it looks as if the EIN was assigned to the entire BOM at 150%.

Maybe Structure in PAU (150% BOM) need to configure it differently way and EIN need to be create in new level
