Error :Could not connect to SAP systemSAP_R3_PLM

Hi,

I have uploaded the Business Package for projects into portal and assigned the iviews to a user(test_abc)...when iam trying to view the iviews by logging in to "test_abc" iam getting the following error:

<b>Could not connect to SAP systemSAP_R3_PLM</b>

Our Portal is only connected to SAP BW system...Not R/3..

Could any one please tell me whether we need to coonect to R/3 system to use this business packages?

also there are some iviews like "BW reports","Select a BW report" etc....

to use the above iviews do we require an R/3 system or Bw system....what is the data source for this iviews.?..iam confused ....Could some one help me on this issue?

Regards,
