MDG BP - Supplier UI & Replication

Expert need below info

We have MDG as HUB, BP is not there at ECC but HUB we have BP, we have created Z BP role and using BP-supplier UI for supplier creation

1. Field Properties Issue - IF we are maintaining field property at below path , same is not getting reflecting at UI

SPRO->Cross Application Comp - >SAP Business Partner ->Basic settings ->Field grouping ->Configure field attribute per BP role

But if we maintain at

SPRO->Cross Application Comp ->SAP Business Partner ->Basic settings ->Field grouping ->Configure field attribute per client ->BUPA

than working

Standard behavior ?

Replication - We have configured SOA replication and while replicating It is green at MDG but Failed at ECC stating that "Grouping XXXX does not exits "

do we need to configure BP as well at ECC ?
