Descriptors are categorical variables that identify individual observations or subgroups. For example, your company may collect supplier lot numbers, shift identifiers, and measuring device identifiers.
Variable  Configurations  Requirements 

Measure ID  Required in Descriptors configurations 
NoteIDs are casesensitive, and duplicate IDs are not allowed. Only measure IDs are required. Measure names are not accepted. 
Type  Optional in Descriptors configurations  Use one of the following values to represent descriptor types.

Scope  Optional in Descriptors configurations  Use one of the following values to represent descriptor scopes.

Use  Optional in Descriptors configurations  Use one of the following values to represent whether the descriptor
values apply to an entire subgroup or to individual observations.

Share within  Optional in Descriptors configurations  Specify the text value that represents the group within which to share
the descriptor list values. The value (group) that you specify must match an
existing hierarchy group. If not specified, or if an invalid entry, the default of Station is used. 
Retain usersupplied values  Optional in Descriptors configurations  Specify an integer value that represents how long, in days, to retain a
list value. Valid entries are between 0 and 365. If not specified, or if an invalid entry, the default of 7 is used. 
List values  Optional in Descriptors configurations  When list values are provided, the Select from a
List collection method is used. When values are not provided, the Enter Values collection method with the defaults of Share within and Retain usersupplied values is used. 
Available Configurations  Chart Requirements 

For continuous control charts, Type is optional in Process Measures and Output Measures configurations. 
Valid type options are: imr, imrrs, xbarr, xbars, imrrs, ewma If not specified, or if an invalid entry, the following defaults are
used.

For defect control charts, Type is optional in Defects configurations. 
Valid type options are: c, u, uprime If not specified, or if an invalid entry, the default of c is used. 
For defectives control charts, Type is optional in Defectives configurations. 
Valid type options are: np, p, pprime If not specified, or if an invalid entry, the default of np is used. 
If Limits is set to recent or any parameter is null, specified parameters are ignored. Subgroup size is required and will be set to 1, if missing.
Available Configurations  Chart Requirements 

For continuous control charts, Limits is optional in Process Measures and Output Measures configurations. 
Chart types of imr, xbarr, xbars, and ewma require both Mean and Standard Deviation for fixed control limits. Chart type of imrrs require Mean, Standard Deviation Between Subgroups, and Standard Deviation Within Subgroups for fixed control limits. 
For defects control charts, Limits is optional in Defects configurations. 
Chart types of c, u, and uprime require both Mean Defects and Sigma Z for fixed control limits. 
For defectives control charts, Limits is optional in Defectives configurations. 
Chart types of np, p, and pprime require both Proportion Defective and Sigma Z for fixed control limits. 
You can specify the amount of data to use for the initial control limit calculations, when Limits = recent.
Specifying default number of observations/subgroups for control limit calculations is optional in Process Measures, Output Measures, Defects, and Defectives configurations.
Numeric values only, USL > LSL.
Defects and Defectives configurations have only upper specifications, not lower specifications.
Numeric values only, UAL > LAL.
Specifying default subgroup sizes for sampling plans is optional in Process Measures, Output Measures, Defects, and Defectives configurations.
Target values are optional. If you enter a target value, RealTime SPC calculates Cpm, a capability index that considers how much the data deviate from the target.
Optional in Process Measures, Output Measures, Defects, and Defectives configurations.
Weight values are optional with EWMA control charts.
Process Measures and Output Measures configurations, when control charts Type is set to ewma.
Weight values must be numeric values 0 ≤ Weight ≤ 1.
If control charts Type is not set to ewma, weight is ignored. Subgroup size is required and will be set to 1, if missing.
