Hi Joao,

A surveillance-type validation rule should work as you say, comparing the
current values of the left side with previous values of the right side. I
don't know why you aren't seeing this behaviour.

When you create a new surveillance-type validation rule, be sure to give a
non-zero "Sequential sample count" to compare with periods immediately
preceding the current period, and/or a non-zero "Annual sample count" to
compare with the same period in past years. If you choose both, it will
compare the current data with a range of sequential periods in this year
and in past years.

If this is not the problem, I would need some more information to
understand better your situation. If you can reproduce the problem on the
demo system https://apps.dhis2.org/demo/, or on another system to which I
can be given access, that might help the most.

Cheers,
Jim
