Thanks everyone for your support and votes! We’re working on enabling commenting for dashboards and reports in the Power BI service soon. Stay tuned.Data Consultant commented
Capture comment, name (or user id) of person making the comment, and date-time of comment. Display in area of report where the report creator has reserved space for this need, and/or allow option for a pop-up of comments when clicked on to save space on report page / tile. Associate comments to the report or dashboard object for retrieval later. Otherwise this tool loses out to other tools... This goes same for Write Back feature too. Users want to enter parameters or scenarios and see how the resulting analysis (projection) changes. That is "BI". Otherwise it is just reporting and fancy visualizations without any real decision support use.
