When I create an infopackage on an export datasource of a basic infocube, the Processing option "Data Targets Only" is greyed out so I cannot select it. Why does the system prevent me from selecting "Data Targets Only"? (Although we are on BI 7.0, we want to use an infopackage for consistency purposes.) Update rules to downstream data targets are all active and executable allowing us to send data through a PSA to targets, but we would like to totally skip the PSA due to space constraints.
