RE: What should I take care of when storing my work in the future?
Ok, so I don't konw what your work flow is or why (or if) its necessary to save the reports separately from the data table.
If it were me, in the report, from the top most red triangle menu (RTM), I would use Save Script>To Data Table. Then each time I updated the table I could just run the script to generate the report. If I needed a static copy of the report, I would journal it. A journaled report is separated from the data and can be saved as any other file.
