Data Uploader - protect existing data from being overwritten?
I am working with several consultants from varying solutions at our company who are contracted at any given time to evaluate various pieces of an enterprise software solution at any given time. Sometimes a company may ask us to re-evaluate the same solution every 2-3 years to see if they are using it as efficiently as possible.
It's being suggested to us to use the a single analysis sheet for all projects regardless of when they take place or what solution they apply to, which we can do, but I'm concerned that when they use the Data Uploader to load the latest software evaluation settings into the sheet that there's a possibility they may choose Replace instead of Merge which could result in either they lose previous evaluation data/results, or they write over a colleague's results.
Any ideas on how to protect data already in the sheet from being compromised?
