Hi, Scott.
I'm not shore that it is the right place for this question...
I'm facing with discrepancy in results received from different sources about MTI.
for example for one file the query above returns one row:

But other methods show different results:
query: select INDEX_NAME from qsys2.syspartitionindexes where table_name = 'FPGPF' and index_type = 'TEMPORARY'
result: 2 MAINTAINED TEMPORARY INDEXES
dump plan cache shows two MTIs on this table used in SQL queries:

Using ACS - SQL Performance Center I found plan that contains the lost MTI:

This situation is typical for many files. Sometimes the results are different between all these methodsIs. Is qsys2.condidxa shous correct information? Where is the truth?
MTI_INFO is not ready.. how to use QQQOOOCACH with "I" is not clear...
