Hi,

If the annual denominator value is 451.5 and the monthly numerator value is
149 then the annualised monthly value of 401.5 % is correct.


Num x Factor = 149 x 12 (approx.) x 100 = 178 000

Ind value is then 178 000 / 451.4 = 396 %

The annualisation factor in DHIS is based on days and not months, that is
why it is not exactly 12, but very close to 12 at least.

Your problem seems to be the dnominator data typed into DHIS.
Is the annual value really 451.5 or is that a montly estimate of the annual
value?
