Re: DHIS zeros and saving data?
That's true Murod, but most of the data elements collected will have an
aggregation operator "SUM" and never be averaged (in DHIS at least).
Typically the average data elements such as population estimates are never
'0', so this has never been an issue for data processing.
When people have reacted to the ignoring of '0' values it has mostly been
related to completeness issues. As Jason says the complete button can solve
that problem.
You can also define certain data elements (called compulsory) to be filled
for a a dataset to be considered complete.
Note that the default behaviour in DHIS is to ignore the '0's. If you want
to save them, then you must set 'Store Zero Data Value' to "Yes" for each
data element where you want this behaviour.
