When I run the below query as an admin it returns results however when run as a user it does not. The user is a power user with admin rights, the time picker is set the same. There are no exclusions from the users rights to indexes ( as far as I can tell)
index="login_data" sourcetype="Login_Data"[search index="hrxref_data" sourcetype="HR_XREF" earliest=-60d (LVL1_MOID="xx" OR MOID="xx") | table SignonID ] | eval SignonID=upper(SignonID) | bucket _time span=1d | stats count as LoginCount by _time, SignonID | join type=outer SignonID [search index="hrxref_data" sourcetype="HR_XREF" earliest=-60d (LVL1_MOID="xx" OR MOID="xx") | table SignonID EMP_NAME ] | timechart values(LoginCount) as LoginCount by EMP_NAME
It looks like the search should work providing the user has access to all the same knowledge objects and indexes.
Check try the following 2 searches.
index="login_data" sourcetype="Login_Data | stats count by SignonID index="hrxref_data" sourcetype="HR_XREF" | stats values(LVL1_MOID) values(MOID) values(SignonID) values(EMP_NAME)
If any of the searches or columns are empty, look to see if the user can see the index and that field extractions are not private.
What does the job inspector say (little 'i' icon near the time picker)?
Could some field extraction take place in an app's props or transforms, and the user-role does not have access there?
