Difference between CSP legal entity set-up and SAN remit-to set-up
When supplier creates a remit-to address in the SAN (no concept of legal entity in SAN), without a remit-to name, the invoice from name will show the supplier name that is on the supplier record in Coupa.
There are differences when a legal entity is created in CSP and Remit-to address is created in the SAN.
1 - When supplier are first sent invitation to join the CSP they have the registration window where they can set the Company Name. By default the Company Name is set as the Supplier Name that is set on the supplier record in Coupa. This company name can be changed and will be the public profile name.
2 - Then when the CSP account is created, the legal entity can be created and here the legal entity name can be set.
3 - When invoices are sent using this legal entity, we will see the legal entity name on the Invoice From section on the legal invoice.
