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.
