I believe you can use search query like this
@accountRequests((attributeRequests.name:jobCode OR attributeRequests.name:jobTitle ) AND source.name.exact:“Your Source”)
I found it here : Identity Attribute changes audit report - #3 by gauravsajwan1 ,and it was suggested by @mcheek
Combine this query using Relative Date Comparisons. Find more here: Building a Search Query - SailPoint Identity Services
