The imported data can be compared to:
1. An earlier forecast for the same period
2. A set absolute limit for the series
3. The earlier values for the same series, a previous import
When the system finds values that deviates from the set rules above the system can either be set to:
A. Warn.
A warning alert is sent to inform that values outside of the bounds has been detected. The data is still imported into the system.
B. Block
A message is sent to inform that values outside of the bounds has been detected and the import is blocked from the system so that the values are not imported.
