Order Column
Column Type = Integer
Enter the order in which each input risk record is to be processed in the risk sampling routines. Records are processed in ascending order of the values specified in the Order column, and any ID set or time period that overlays any portion of a lower ordered input record for that same set will supersede it for that portion.
For example, record A with Order=1 could specify that demand for all zones use “Distribution A” for all of 2005. Record B with Order=2 could then specify that Zone 4 demand were to use “Distribution B” in December of 2005. Then in each risk iteration, all zones but Zone 4 would sample from Distribution A for all of 2005, Zone 4 would use the sample from Distribution A for January through November, 2005, and then Zone 4 would use a sample from Distribution B for December, 2005. If the Order value of the records were reversed so that B were read first, record B would be completely superseded and would not be used. All demand sampling would then be based on Distribution A.
NOTE: Values do not need to be positive or contiguous, but all values must be unique. Results for records with duplicate Order values are unpredictable.
NOTE: The column type for this column should not be changed from Integer. If this column is "Text" type, it will cause unpredictable results when using record overrides or correlated variable specification. When a Run is started, the model will automatically check this column type and raise an error and stop if this is not column type "Integer".
