AWR report analysis

 Hello All
I have the following problem:

When I create an awr report within two snapshots say 24139 and 24140 , I get from the part of "SQL ordered by Elapsed Time" the following information:

SQL ordered by Elapsed Time DB/Inst: DEVC/DEVC Snaps: 24139-24140
-> Resources reported for PL/SQL code includes the resources used by all SQL
statements called by the code.
-> % Total DB Time is the Elapsed Time of the SQL statement divided
into the Total Database Time multiplied by 100

OUTPUT

---

Elapsed    CPU                                  Elap per     % Total
Time (s)     Time (s)     Executions       Exec (s)      DB Time         SQL Id
