HsSetValue to submit Forecast

Summary

Looking for VBA script to call Business rule script (Agg Script)

Content

We are thinking about using the HsSetValue function to submit our forecast in excel. After pressing "Submit Data" we want to trigger an Agg script via a VBA button. 

• Can anybody provide me with a VBA sample script?
• What is your experience with using HsSetValue instead of using a "Form"? Any drawbacks?

Thanks
