AX2012 Displaymethods not shown on SSRS report


I have created a number of displaymethods on SalesTable on a test-system and have succesfully added these to a SSRS-report. The report shows the values as expected. When moving the report (and displaymethods) to a production-system all the displaymethod-columns are empty - I have created a job that verifies that the displaymethod is working - Does anyone have any ideas?
