Change storage location and plant for Return Delivery (outbound)

Hi,

I'm trying to achieve the following:

Sales orders contained the 'normal' plant. Whenever a return delivery is created it should default the plant to a 'return delivery plant / storage location'. I've looked in to this and it seems we've got multiple options, however i would like to check:

- Implement V02V0002 user-exit and link with 'return' movement type. Will this ensure plant change aswell?

- Use standard RETA rule and define ?situations?. Could somebody clearify whether we can achieve our goal with this: Change plant and storage location?

Any suggestions to achieve the above are very much appreciated.

Note: Material contains both views for 'return plant/storage location' and 'normal plant/storage location'.

System is R/3 4.6c with IS Retail activated.

Kind regards,

Tim
