Procurement Project and Lot Use

Procurement Project and Procurement Project Lot Why do we need the two? Procurement Project Lot does already refer to the Procurement Project! I understand we do in order to not repeat the ProcurementProject data and get into inconsistencies. - Common information about the Procurement Project is detailed in the ProcurementProject component, whilst the specif Lot-related information goes in the the ProcurementProjectLot Component. The ProcurementProjectLot ASBIE ProcurementProject is not used then to describe the Project.
