Assign BP relationship type

Hello,

I have maintained new BP relationship type and assigned them to BP relationship category in SPRO->Cross App Components->SAP BP-> BP relationships->Define Relationship Types.

I can only view the relationship category in BP , is there a way to assign the BP relationship type to BP ?

Even when we load the BP relationships from Legacy by passing two different BP relationship types to the same BP relationship category, it only accepts one.

Thanks,

Sheetal
