Hi Vivek,
#2 sounds like SAP CRM BP which is not my case. I'm not migrating or transferring Customer Masters from XD01 ECC to SAP S/4 HANA. I'm creating Customer Master Manually in S/4 at first once I get the correct fields I want then i'll use LSMW.
And for #1 That is basically in my screen shot for the config part of BP Role. which is not showing as Mandatory.
Thanks.
