We are creating ideas using Idea REST API as described here:

https://docs.oracle.com/en/cloud/saas/supply-chain-management/19b/fasrp/op-fscmrestapi-resources-11.13.18.05-ideas-post.html

However, we are unable to set CreatedBy/Posted By parameter, although we understand this is supported. We are getting error: Attribute CreatedBy in view object IdeaSummary cannot be set.
