Thanks for the Update .
and for your next query of Vendor Screening without transferring the Banks?
as per standard process (Customers, Vendors, Contact Persons) the Master Data is transferred using Change Pointers, hope your client also using the same process. if you are using the Change Pointers then Vendors get transferred and screened in GTS against to SPL Data .
hop you know that in GTS, SAP has provided various types of Screening for the BPs (A1,B1 and C1 Screening). i am sure these processes are running with no issues in your GTS system.
please let me know if you have any further clarifications on this.
request you to mark this if it is helpful .
Thanks,
