1. Set the permissions on the respective Presentation Catalog folder so the user cannot save there
2. Why not include another view in the analysis (eg Legend view) that the user can access to show them the column definitions, rather than the user-unfriendly option of having to go and edit the report?
Thank you rmoff. Your suggestions help my future:) Since I have never used a legend view, I may not imagine it. After that, I will use better ways to show column formulas. However, I also want to learn option 1. Which privileges should I set the presentation catalog folder? Write option gives the save ability:S
"open" must be enough. "write" will enable the "save", but just with "open" they will not be able to save in the same place, so impossible to override your own analysis.
They will be able to save it somewhere else like "my folder", but this will not affect your own (official) version of the analysis.
