Table are not prefixed with Schema in SQL request - Unable to get Data

Question

I began this new thread because I closed the [previous one|Unable to get data (DSN connection); a little bit early, I believed it was OK but no the problem still here.
First my architecture :
Oracle 9g
+500 Reports made under CR developper 8.5 or 9.0
Report opened in VB .net application, framework 2.0 using CR runtime 8.5 and 9.0
We want to upgrade CR version to 2008, so modification of reports will be done with CR 2008 Developper, and we want to
use only CR 2008 runtime.
The problem :
Everything works fine in CR Developer, but the same report with the same parameters failed when called inside .net.
The error is "Unable to get data", the database connection is OK but the queries mades from inside the report are wrong :
The tables/views in the from statement are not prefixed with the Schema, so Oracle don't find them.
Example (SQL monitoring done with TOAD)
Execution of postes.rpt report directly in CR :
Timestamp: 10:30:03.881
Successful logon attempt (session tag: 0x6464CB8)
username: 'APPLI_HUET'; database: 'DEV'
SELECT ...
FROM  "COMMUN"."ETAB" "ETAB" INNER JOIN "GESTION_DES_TEMPS"."POSTES" "POSTES"
ON "ETAB"."N_ETAB"="POSTES"."N_ETAB"
WHERE  "POSTES"."N_ETAB"=2 ORDER BY "POSTES"."N_POSTE"
Timestamp: 10:50:29.178
Logoff (session tag: 0x6464CB8).
Same report, same authentication but throught .net program :
Timestamp: 11:01:24.569
Successful logon attempt (session tag: 0xA93FC38)
username: 'APPLI_HUET'; database: 'DEV'
SELECT ...
FROM   "ETAB" "ETAB" INNER JOIN "POSTES" "POSTES"
ON "ETAB"."N_ETAB"="POSTES"."N_ETAB" WHERE  "POSTES"."N_ETAB"=2 ORDER
BY "POSTES"."N_POSTE"
Runtime error occurred: 942 (ORA-00942: Table ou vue inexistante)
The .net code :
Dim _report As New ReportDocument()
_report.Load("report.rpt", OpenReportMethod.OpenReportByDefault)
Dim myConnectionInfo As ConnectionInfo = New ConnectionInfo()
myConnectionInfo.ServerName = "DSN_file"
myConnectionInfo.UserID = p_Userid
myConnectionInfo.Password = p_Password
' to see code in this method se my original post
SetDBLogonForReport(myConnectionInfo, _report)
SetDBLogonForSubreports(myConnectionInfo, _report)
Dim frmViewer As New CrystalReportViewer
frmViewer.CrystalReportViewer1.ReportSource = _report
frmViewer.Show()
Any ideas ?

Thanks for the and sorry but I don't understand.
I've made a research of Location on this forum the more intersting thread I've found is rpt-files do not function anymore after deploying to a different database, but I still don't understand.
I take a look at all code sample and I can't found anything.
You say that .Location need to be set, indeed Location property of CrystalDecisions.CrystalReports.Engine.Table object only contains table name.
I tried to overrides this value by the fully qualified table name (ie Schema.Table, for example GESTION_DES_TEMPS.POSTES), and it work  BUT it wouldn't be the solution, my code is designed to be generic, I can't have a database to know wich schema add before differents table name.
Why when we execute the report directly in CR 2008 developper we don't have to redefine the table location ?
Another test :
I've made a new report directly in CR 2008 with a DSN, launch it in .net with the same DSN (server) : OK
Then I launch it in .net with another DSN, it work also.
Why report done with Crystal 8.5 or 9.0 have this problem ?
I'me gonna be mad....
