Hi Lars,

I am in process of creating an indicator say for example

Number of days equipment not working 
= [ {(Total Number of days in current month) - (Number of days equipment working)}/1 ]

Here nominator is defined as an mathematical expression 

[ {(Total Number of days in current month) - (Number of days equipment working)}]

And here denominator is 1 and "Number of days equipment working" is an aggregated data element.

My query is how i can use mathematical operator "D" in above nominator for calculating 
"Total Number of days in current month" which is not a data element in expression given below ie.

[ {(Total Number of days in current month) - (Number of days equipment working)}]   


Or, is there any other way to calculate or use "Total number of days in current month" while making indicator specially since it is a variable and varies month to month, say for example in Fab its value will be 28 or 29, in March its value will be 31, in April its value will be 30 etc.

Please clarify how we can make indicator like above and how we can use "Total number of days in current month" which is not a data element ?

Regards
Brajesh Murari

Hi Brajesh,

it indicates the number of days in the aggregation period. So if you ask for the aggregate value for a quarter, it will return 92 (or 91). You can then use this to calculate things like average number of something per day.

regards,

Lars
