Multiple vendors assigned to one BP in MDG 9.2

Dear Experts,

We are doing some testing with MDG 9.2 on S4 1809 and are evaluation different topics. One is related to Business Partner and assigning multiple vendors to that. In MDG UI I can see multiple ERP vendors assigned to BP, but in transaction BP there is only one vendor shown. Also table BC001 shows only one entry and MDS_LINKS also shows only one assigned vendor. Maybe you can help me in understanding the concept. Is there some documentation available on this particular topic? Maybe some configuration is missing?

Thanks for helping me out here…

Best Regards

Matthias
