ST12/ ST05 Details trace list

Hi All,

Just would like to know after I run the ST12, and open the trace list, my object: eg: EKPO are able to find it the trace list.

Then i tried few times after the new indexes created in EKPO, i not manage to find the EKPO object in the details trace list in ST05. The program is accessing this table to retrieved the EKPO details. Is anyone have ideas how is doesnt show in the list even i hhave display out the all trace lists.
