SAP offers 2 different processes of Vendor Returns: returns with Returns Delivery Ref to Inbound Delivery and returns with Returns PO. So what is the difference? In this blogs I will compare this 2 processes with EWM steps.
My Testing is based on Embedded EWM - S/4HANA 1909.

Master data
When using Returns PO, Vendor master data and Material Master data need some additional data as below.
- Vendor Master data:
For using Return Delivery, in Role Vendor, mark Vendor as Return Supplier.

For using Returns PO, maintain Customer roles for Sales.org & Distribution Channel. Assign Delivery Plant as plant where you returns stock.

- Material Master data:
For using Returns PO, maintain Sales View for material.

Testing
Vendor Returns - Using Returns Delivery Ref to Inbound Delivery
Step 1: Create Return Delivery Ref to Inbound
Tcode: /SCWM/PRDI
Before this step, a Inbound Delivery is created and GR is posted.
Stock is still in GR-ZONE, mean if you already putaway stock and confirmed putaway WT, you need manually transfer stock to GR Zone.




Step 2: Create Picking WT and Confirm WT
Tcode: /SCWM/PRDO
Note: Stock is taken from GR-ZONE to GI-ZONE


Step 3: Post GI
Tcode: /SCWM/PRDO
Post GI after picking is completed.
Note: Stock Type is Q3 (or F1)

Material Document with Mvt 122 is created in S/4HANA

Vendor Returns - Using Returns PO
Step 1: Create Retuns PO
Tcode: ME21N
Select PO type - PO Return and mark Item as Return Item
Step 2: Create Outbound Delivery
Tcode: VL10B


Step 3: Create Picking WT and Confirm WT
Tcode: /SCWM/PRDO


Step 4: Post GI
Tcode: /SCWM/PRDO
Post GI after picking is complete.
Note: Stock type is Q4 (or F2)

Material document is created with Mvt 161

*****
Important note!!!
If you want to return stock rather than your original GR stock type, you must set up Stock Determination for other Stock type.
Example: GR with inbound delivery, stock type Q3. But you want to return stock with stock type Q4 or F2, it's possible.
IMG: EWM > Cross process Setting > Stock Determination
Create a Stock Determination Group and Assign Stock Determination.
You can create many stock Determination to picking more than 1 stock type for return.

Next step to assign Stock Determination Group to your Product Master.
