/*
This test is applied in the reporting layer for Main KPIs,
specifically on reporting.mtd_aggregated_metrics.

It just ensures that for the last available date, the sum of metrics
for any dimension provides an equal or lower aggregated value compared
to what is expected at Global level, up to a certain threshold. 
This is because some dimensions depend on Deal, and not all users 
have a Deal, thus it's normal that the aggregation might not match the 
Global value on a given metric. 

However, the aggregation cannot be higher, with a certain tolerance, 
than the value reported in the Global dimension.
