What is the correct procedure for making changes (quantity or delivery date) to partially supplied SOs? If the SO is completely not delivered, it is easy (reset to quotation, change, reconfirm).

Example:

SO with three items

Item 1 50 pcs 25 pcs delivered

Item 2 100 pcs 0 delivered

Item 3 150 pcs 0 delivered

Task: Change item 2 from 100 to 80 pcs (variation: to 120 pcs)

Would it really be necessary to manually adjust the OUT transfers (and possibly also the resulting MOs and POs)?

This is a huge problem for us and we are currently despairing...   Is there any hope in V16?
