What is the role of calculationID at datamodel json file?

[brandy81]

Hi All,

As the title says, what is the role of calculationID at datamodel json file?

I had to create many datamodels, so I copied a datamodel json file, then I noticed that there is calculationID for the calculated fields.
It looks unique key... is it okay that I may copy datamodel json file then remove calculationID? I tried and I checked that the removed calculationID was regenerated as I restart splunk.

Could you please let me know what the role of calculationID?

This really needs to be answered - I get an "invalid JSON" note when running it without the calculationID, but when I have it, Splunk says "error in datamodeledit handler: invalid field name"
