3638925 - Create Supplier invoice app assigns all purchase order line items when adding delivery note as reference

Same delivery note number is used for different purchase orders and with different suppliers. Even with pre-selecting the relevant supplier in the header, when adding delivery note reference in Create Supplier Invoice, system assigns all the purchase order line items which are connected to the delivery note number. 

S/4Hana Cloud Public Edition

1. Create supplier invoice with app 'Create Supplier Invoice'
2. Fill header data and add supplier number
3. Add reference with delivery note (same delivery note is used by other purchase orders also with different suppliers)
4. System assigns all the PO line items, despite supplier has been selected in the header

This is current standard system behaviour which relates to a missing functionality. 

For delivery note reference there is no advanced selection criteria. 

Purchase order reference can be used instead of delivery note reference, or not relevant line items can be excluded manually.
