BW integration with Portal

Hi,

We are running EP 6.0 sp11 and BW 3.5. BW Power Users will use Query Designer to publish directly to roles in the Portal. That's all working, but we're having a problem with permissions (we would like to restrict the available PCD folders to prevent user error).

1. What permissions does the report author require in the PCD in order to publish a query directly to a PCD folder?

2. What permissions does the user require on the role in the PCD in order to publish to it?

Thanks,

Marc
