Suppliers in SAP Hybris C4C

Hi,

Our customer wants to maintain Suppliers in C4C. system.

1. Which is the Best Option for keeping Suppliers in C4C?

2. If a Customer is also a Supplier, a simple workaround will be to have an extension field created in the Account Master Data (check box type) and mark the Account as a 'Supplier'. Any better ideas?

Thank you,

Andreas
