Return to vendor - route determination

Hello,

I've got a question regarding the route Determination for vendor Returns with delivery type RLL.

When I create a vendor return delivery with transaction MBRL or MIGO, SAP places a route "000001 - Northern route" in the delivery header.

Unfortunately this route is not defined in our SAP system!

I already checked route determination settings, but I didn't found the reason, why the route 000001 is placed, although it is not known...

RLL is configured to start a new route Determination

See attachments for hardcopies.

Anyone an idea where to change the route settings?

Thanks.

Chris
