Solution:

Based on the official content from learning.sap.com regarding Configuring the MDG-S Validation and Approval of Suppliers (SAP Ariba Supplier Lifecycle and Performance Integration via Managed Gateway for Spend & Network), the correct statements are:

1.A. MDG-S validation occurs before the supplier record is created in Supplier Lifecycle and Performance

oWhen the Enable external validation of supplier creation feature is activated, the supplier request is sent to MDG-S for validation before a new supplier record is created in SAP Ariba Supplier Lifecycle and Performance. SAP Learning+1

2.B. MDG-S validation will work with ERP configurations that do include Master Data Management

oThe external validation feature only works when your ERP configuration includes SAP MDG-S for Supplier Master Data Management. It does not work in ERP configurations without MDG-S. SAP Learning+1

3.C. When MDG-S approves the supplier request, the supplier status becomes “Not Invited” registration (i.e., the supplier is created but marked as Not Invited)

oAfter MDG-S approves (and no duplicate is found), a new supplier is created in Ariba SLP and moves into Not Invited registration status. SAP Learning

Therefore, the threecorrect answe rsare: A, B, and C.
