I use a query below to check data in temp table. Also defined an index. I could sense that after adding the index to the temp table, the query gives the result asap. I would like to know how the index used by compiler. Is there a way to find out list of indexes used by compiler for the query I have used.

Note – I understand XREF gives WHOLE-INDEX for non-indexed tables. but I am not able to find out what are all the index used for indexed table.

DEFINE TEMP-TABLE TT_DATA NO-UNDO
FIELD TT_PART  AS CHARACTER
FIELD TT_DESC  AS CHARACTER
FIELD TT_IN    AS CHARACTER
FIELD TT_VEND  AS CHARACTER
FIELD TT_GLOB  AS CHARACTER
FIELD TT_TYPE  AS CHARACTER  
INDEX TT_IDX1 IS PRIMARY
TT_PART
TT_IN 
TT_VEND
.

FOR EACH <TABLE> NO-LOCK:
 FIND TT_DATA NO-LOCK
    WHERE TT_PART = "015564"
    AND   TT_IN = "VC"
    AND  TT_VEND = "SUPPLIER" NO-ERROR.
    
  IF AVAILABLE TT_DATA THEN
  DO:
   /*ACTUAL LOGIC GOES HERE*/ 
  END. /* IF AVAILABLE TT_DATA THEN*/
END. /*FOR EACH <TABLE> NO-LOCK:*/
