When I'm using the ST05 to trace the table, I got the difference table everytime i trace in the same program.

Why can this happen?

Are you running the same program everytime? or running the different programs?

If you run the same program everytime, where from different tables will come into the picture

See this and do again and see

SQL Trace

SQL trace(ST05) provides the developer with the ability to analyse database select statements. Simply execute ST05

to turn on SQL trace, then execute the statement/program you want to analyse. Now turn off SQL trace using ST05

and click on list trace to view the details.

You can also perform traces on other items such as authorisation objects.

Authorisation trace analysis 1. Open two sessions

2. Execute transaction ST01 in one of the sessions

3. Select the authorisation checkbox, note the other traces

you can perform (SQL, RFC, Table Buffer etc)

4. Click the 'Trace On' button

5. Within your other session execte the transaction/report

you want to trace or get the user in question to do it

6. Return to the session where you turned the trace on and

click on 'Trace Off' otherwise it will continue to record

all athorisation checks

7. Click on the 'Analysis' button

8. Enter appropriate data into selection screen such as

Username, type of trace records (i.e. Authorization check)

9. Click on the Execute button.

10. Report displaying trace results will now be displayed

Some useful transaction related to this are ..

ST01 SAP system trace

ST02 Buffer statistics.

ST03 Workload analysis.

ST04 Database performance analysis.

ST05 SQL trace .

ST06 Operating system monitor ...

From the recorded SQL trace you can deduce:

· Which SQL statements your application carries out

· Which values the system uses for specific database accesses and changes

· How the system translates ABAP OPEN SQL commands (such as

SELECT) into standard SQL commands

· Where your application positions COMMIT statements

· Where your application makes repeated database accesses

· What database accesses or changes occur in the update section of your

application
