SAS EuroBonus - Troubles crediting Sixt rental to SAS?

Has anyone else had trouble crediting Sixt rentals to Eurobonus? I am in the process of switching over from M&M and have not been able to get Sixt to accept my EB number during online check-in and retrocrediting. However, I have been able to get the same rentals eventually credited to M&M.

I realize that this might be better suited in the Sixt forum, but I am curious if any EB members have managed where I have failed.

Yes, was possible without any problems.
Used to post EB-Miles, when Sixt had the campaign last year.
If not possible for you at online-checkin, just do it at the counter when getting the car.

Hi,

I use the following string when I book with Sixt: EBxxxxxxxxx

This works for me and the booking system accepts it.

Part of the problem is that I usually call the local office and ask them to deliver/pick-up from my home. I have tried to give them my EB number but they never add it to the location, hence I am trying to add it either online or retroactively.

Nonetheless, I still find it odd that the system does not accept my EB number but can manage with my M&M number. Probably best bring that I bring this up in the Sixt forum.
