SSO federation b/w SaaS & PaaS–Any tip to have multiple fusion accounts access single OIC account

Summary:

We recently configured SSO federation between IDCS (used by OIC) and Oracle Fusion, where Fusion is the “Identity Provider” and IDCS the “Service Provider”.

Users can now access OIC by using Fusion apps credentials but we need to have the same number of accounts FA vs OIC.

Due to OIC license limitation we’d like to know if there is a way to avoid or skip the need to have “1 to 1” accounts 

Content (required):

We recently developed a new VBCS web app to perform certain manufacturing tasks.

We embedded VBCS app link in Oracle Fusion

We can now call the VBCS app successfully from within Fusion, HOWEVER, users were prompted to enter OIC credentials each time.
