In AX 2009 we could change the query behind a personalized CUE. This seams to have been removed from AX 2012.
But we that can develop, still have a chance, using X++.
Run the following job script, and you will get the query up, so that you can change the query.
This will bring up the normal query form, where you can make your changes, and then press OK to save the new query in you Cue.
Take care and happy Daxing.
