The MERGED_ATTRIBUTES tables provides a list of all user-defined and derived attributes that are available in the project. The user-defined attributes include the BY variables and any additional variables that have been imported into the project. The derived attributes that are also added in this table come from the OUTSTAT, OUTSUM, and OUTMODELINFO tables.
In addition, the demand classification attributes are included in MERGED_ATTRIBUTES.
Some variables are in multiple tables with duplicate names. When they are added to MERGED_ATTRIBUTES, they are renamed to distinguish them. The following table shows how the original variable name matches to the renamed variable in MERGED_ATTRIBUTES.

SAS Visual Forecasting analyzes patterns in the time seriesan aggregation of transactional data into specified time intervals and sorted according to unique combinations of the default attributes (BY variables) for a project and classifies these patterns to generate attributes. Demand classification attributes represent characteristics of times series such as intermittence, volume, volatility, and seasonalitya regular change in time series data values that occurs at the same point in each time cycle.. See Demand Classification for complete descriptions of these demand patterns.
Changing any of the Project Settings for this project can lead to errors.

Label |
Variable Name |
Description |
|---|---|---|
|
Volume Volatility Class |
_VOLUME_VOLATILITY_CLASS |
values that identify different ranges of volume and volatility in the time series. Time series that exhibit high volatility are difficult to forecast accurately and might need special attention to identify any inputs that might generate better results. In the Filters pane, you can select from the following patterns that have been detected in the time series.
|
|
Demand Class |
_DEMAND_CLASS |
A specific set of classifications based on patterns detected in the time series. These classifications are used to segment the time series in the Demand Classification pipeline. See Demand Classification for more information. Select from the following possible values for the _DEMAND_CLASS attribute. Some of these values might not show in the Filters pane if no time series meet the criteria for that attribute.
|
|
Seasonal |
_SEASONAL |
indicates whether the time series is seasonal. Seasonality is determined by a significance probability of 0.01 or less. In the Filters pane, select Y to show only seasonal series or N to show only series that are not seasonal. Select ND for time series for which seasonal patterns could not be determined. |
|
Intermittent |
_INTERMITTENT |
indicates whether the time series is intermittent. In the Filters pane, select Y to show series that indicate intermittent patterns or N for series that are not intermittent. |
|
Seasonal Intermittent |
_SEASONAL_INTERMITTENT |
indicates whether the time series is seasonal intermittent. In the Filters pane, select Y to show series that are both seasonal and intermittent series or N for series that are not a combination of seasonal and intermittent. Select ND for time series for which seasonal intermittent patterns could not be determined. |
|
Retired |
_RETIRED |
indicates whether the time series is retired. In the Filters pane, select Y to show only series that are retired or N for series that are not retired. |
|
Short |
_SHORT |
indicates whether the time series is a short period. In the Filters pane, select Y for series that indicate a short pattern or N for series that are not short. |
|
Volume |
_VOLUME |
the volume of the time series. In the Filters pane, select from LOW , MEDIUM , or HIGH . |
|
Volatility |
_VOLATILITY |
the volatility of the time series. Usually, series with high volatility are harder to automatically forecast than series with low volatility. In the Filters pane, select either LOW or HIGH . |
|
Demand Span |
_DEMAND_SPAN |
the length of the time series. This is used to determine whether time series are year round or seasonal prior to further classification for the Demand Classification pipeline. In the Filters pane, select any of the following options.
|
|
Trailing Zero Length |
_TRAILING_ZERO_LENGTH |
the number of trailing zeros in the time series. In the Filters pane, select from any detected numeric range. |
|
Maximum Cycle Length |
_MAXIMAL_CYCLE_LENGTH |
the maximum value of the demand cycle lengths detected from the time series. In the Filters pane, select from the values detected from time series. |
|
Volume Measure |
_VOLUME_MEASURE |
the actual volume measurement value of the time series. In the Filters pane, select from a numeric range, starting with the lowest detected volume measure in the time series to the highest. |
|
Demand Interval |
_DEMAND_INTERVAL_MEASURE |
the median value of the demand intervals. This value is used for detecting if the series is intermittent or not. Select from the numeric values detected in the time series. Note: This attribute
is listed in the Filters
pane as |
|
Volatility Measure |
_VOLATILITY_MEASURE |
the actual volatility measurement value of the time series. In the Filters pane, select from a numeric range, starting with the lowest detected volatility measure in the time series to the highest. |
|
Status |
_STATUS_ |
a value that indicates whether analysis for each time series was successful. You can select one or more of the following conditions.
|
In time series projects, you can use these attributes to create filters in all of the viewers. See Viewers for Time Series in Your Project for more information. The filters are listed in the Filters pane by the label.
