 Essentially, an indicator is a formula that can be composed of multiple data elements, constant factors, and mathematical operators. In order to define a new indicator proceed with the following steps.

A description of the numerator/denominator must be provided in the "Description field". This should provide a clear description of the numerator/denominator. This field is required.

Follow the same procedure in order to define the denominator.
+ The components of an indicator formula are listed below.
+
+
+ Data elements: Will be substituted by the data value captured for the data
+ element.
+
+
+ Constants: Constants are numerical values which will remain the same for all
+ indicator calculations. This is useful in order to have a single place to change values
+ that might change over time.
+
+
+ Days: A special operator "D" is available in formulas. This operator will
+ always provide the number of days for a given indicator calculation. As an example, if
+ you wish to calculate the "Percentage of time vaccine refrigerator was
+ nonfunctional", you could define the numerator as ("D"Number of days
+ vaccine refrigerator was available"")/"D". For example, if the
+ fridge was available 25 days in June, the indicator would be calculated as
+ (3025/25)*100=17%. If you were however to calculate the total for Quarter 1, the number
+ of days ("D") would be equal to 31+28+31=90. Thus, the "D" paramater
+ will always be the number of days in the period of interest.
+
+
+ Org unit group counts: Org unit groups can be utilized in formulas and will be
+ substitued by the number of organisation units in the group. During aggregation, the org
+ units in the group will be intersected with the part of the org unit hierarchy being
+ requested. As an example, this lets you use the number of public facilities in a
+ specific district in indicators. This is useful e.g. when creating facility
+ infrastructure surveys and reports.
