Error refreshing report after applying security restrictions in IDT

Hi,

I have created a report and now the requirement is that the user should be able to view data of his profile only for which i have created restricstions at universe at Business layer.. But after applying these if i refresh by the user id i get the error where as on removing this no error.

"An internal error occured while calling 'porcessDPCommandsEx' API. (Error: ERr_WIS_30270) (Error: INF)".

If i refresh using any other id other than used at restrictions the reports is getting refreshed. Please advise.

This is on BOXIR4 SP3.

Thanks in advance.
