Portlet Cannot Be Rendered


Reputable Poster
We have an E1 page displaying 3 Portlets.

Everything appeared to work well in our DV and PY environments, but when our Users started using it in PD we're getting the following sporadic error:-

"Portlet cannot be rendered: Portlet is not available or is not of the right type (FDA - browse or edit) to run in an EnterpriseOne page"

It seems to be random which Portlet(s) throws this error. The major difference between our environments is that Production has Single-Sign-On implemented.

Anyone have any ideas why this might be happening?
