Hi,

We got a requirement from our current healthcare project where they have many doctors who are their contingent employees and visits hospital like twice a week or once a week. Client creates a contract with all these doctors in their legacy system and manages the payment via integration with SAP application. Recently they migrated to Oracle cloud and are looking for a way to create such contracts with their doctors who are their contingent employees in Oracle also. They also want to process payments of these doctors in Oracle.
