I had faced the below issue ,While running the Payables invoice data Diagnostic test in R12. For that issue we had raised a Service request with Oracle. But no further progress from Oracle Support.

Patch Oracle Diagnostics Tools, R12.IZU.A.DELTA.4 (6497339) is installed

If the XML file for this test was delivered by Oracle Support Services, contact the support representative for assistanceXML File Information

XML Engine Version = 3.2.1

File Name = APListXml.xml (File Version = 120.0.12000000.8, File Location = ap/diag, Date = 2008/04/24)

But Finally we find out the resolution. That issue occurred with synonym of AX_EVENTS Table.

Solution:
1. Recreate the grants & synonyms through adadmin & Complie Apps Schema.
