BMXAA0029E YOU ARE NOT AUTHORIZED TO PERFORM THIS ACTION WHEN TRYING TO SET QUERY AS DEFAULT OR EDIT AN EXISTING QUERY
Know issue (IV30369) which is fixed in Fix Pack MX7504. The problem with this fix is that it does not expand the saved query if there is no default query specified. A separate APAR (IV34306) has been raised for this problem. If clients set a default query then they won't run into this problem.
