Hi Jason
Good to hear form you, I hope you are well.

I agree, that is a good solution and it works very well when you implement it as a function you can call form a SQL View, then you can use the API to setup a cron job or use other means to take care of the frequency. There is a lot you can do with this approach.
I was also able to setup the indicator using the API, but we want to allow the user to create these indicators. Both SQL and the API are a little beyond what they can or want to do. I think the indicator editor is due for an face lift ;-) there are other things to consider, for example having 20K constants to choose from or formulas that requires a data element with an option combination that is not part of the category combination assigned to the data element.

Best regards,
JM

We have followed this approach for indicators which cannot be calculated with relatively simple formulas provided by indicators, such as those requiring "IF...THEN" types of calculations.
