Dory is correct on the sync.
It is best practice to alwaysinclude a Period Cost, even if it is 0. Especially if you are using RCA or the Program Analyzer.
The Inclusive Tag means that the system will bring in the Program, even if there is no Period Cost listed. You can set other options like Only if Period Cost and Operational. These are intended to help you filter out Programs that might be Operational or not inherently for an ROI calculation.
