Thank you for your response. I have mapped all the fields. What I find confusing is looking at the structure the InventDimCombination table is the primary target while EcoResDistinctProductVariant is a child. This makes no sense to me as in order to form the relation from InventDimCombination I must already have the EcoResDistinctProductVariant record. There is nothing from staging to map to the target for the unique identifier as it is system generated.
