There are two scenarios (that I can think of off the top of my head) where multiple data functions are run at one time -- upon opening of a DXP and when data functions are set to update automatically. When data functions run, the user gets a list of errors or warnings in the bottom left. It would be helpful if that dialog specified which data function generated the warning or the error.
For example, I am currently getting a warning that says -- Column `API14` has different attributes on LHS and RHS of join. I am using the dplyr package in several data functions to join tables. It would be really helpful if I knew which data function the error applied to rather than now having to go run them individually.
