Com.sap.ip.bi.bex IView - SYSTEM parameter in Portal

Question

Dear Experts,
We are calling the iview com.sap.ip.bi.bex from the Portal system passing the parameters u201CSystemu201D and u201CTemplateu201D to invoke BI queries in a BI 7 system.
eg: http://<sap portal server>/irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fcom.sap.pct!2fplatform_add_ons!2fcom.sap.ip.bi!2fiViews!2fcom.sap.ip.bi.bex?System=BISystemAlias&TEMPLATE=ZYQ_PD_LOGISGENEX
But we find diferences if we use uppercase or lowercase letters in the parameter u201CSystemu201D across our landscape.
Development Portal System
SYSTEM => Error (#1.5#00145E23B5DD007200000028000014240004987887685067#1293543342088#com.sap.ip.bi.base.exception.BIBaseRuntimeException#sap.com/irj#com.sap.ip.bi.base.exception.BIBaseRuntimeException#YP05914#3173##n/a##593456c6128711e0bd5b00145e23b5dd#SAPEngine_Application_Thread[impl:3]_5##0#0#Error##Plain###Exception thrown: com.sap.ip.bi.base.exception.BIBaseRuntimeException: Unknown Error) => Portal System Error
System => OK

QA Portal System
SYSTEM => OK
System => OK
system => OK
Production Portal System
SYSTEM => OK
System => Error (Internal error. No esid found) => This is a BI System Error
system => OK
This issue is strongly bothering us, since we cannot transport from Development to Production because they behave differently.
Any ideas?
Thanks in advance,

Dear Pramod and N Bansal,
Thank you very much for your help!
Finally my problem was solved. The problem was never about the parameter, as we thought initially. When we used SYSTEM, Portal didn't recognize de parameter, and it only worked because when the parameter is spelled wrong (or it's absent), the BI Master System is used.
The correct parameter is (and it always was) "System".
Moreover, we realized that it's not enough to define the alias of the referenced BI system in the Portal System. It's also mandatory to define that same alias in the default system that is created in the installation of the BI system (located at pcd:portal_content/Systemlandscape/SAP_BW of the BI System).
I hope this could help others having the same problem.
Thanks again for your help.
