We found one of the switchs was not turned on correctly. The difference was in DEV everything was turned on, in PRD where the sandbox systems were copied from, the switches were not turned on. The difference is PROD vs. DEV stsytems.
Note 855959 explains this.
"As per note 855959 the original activation of Extension EA-PLM in PRD failed because the system was in Production mode in SCC4. We manually imported the 3 BC Sets that make up EA-PLM (EA-PLM-AKH, EA-PLM-IMG and EA-PLM-MENU)"
