Expand your regular import settingsfile with one more line:
/blockwarnings:Min@Max
Note that using the Block option the whole import will be blocked and not only the deviating data points.
The ’Min’ option blocks the import if the data contains values that are lower than the minimum value set for the series and the ’Max’ option blocks the import if the data contains values that are higher than the maximum value set for the series.
The min and max limits are found in the forecast series model settings.
For more detailed information read the ConsoleUI manual, action import.
