Hi,

I am trying to use REST API  Update a project descriptive flexfield provided in this Oracle documentation link  to update a Project DFF on Project Foundation application that has no context defined - https://docs.oracle.com/en/cloud/saas/project-management/21b/fapap/op-projects-projectid-child-projectdff-projectid2-patch.html 

Can you let me know if __FLEX_Context is mandatory?
