I have a dataset that when that creates a role of "residual" vs. "input" for several variables when added as a data source in E-miner. I thought it might have to do with the % missing so I choose the Advanced Options and changed the percent missing threshold and ran but it did not change the role to input. How does the "residual" role get determined? I can manual change them to input but I want to understand if there is an option controlling this.
Thanks
Almost, the variables start with "RD_". Why is that a specific variable name I shouldn't use? If so what else should not be used?

This post gives a list of other variables with reserved names or prefixes in EM:
You can also take a look at this post about global metadata to see how to programmatically change variable roles, levels, etc. instead of manually:
thank you, makes sense to me now!
