The sample data object attributes are on the Sample Data Attributes section of the Sample tab.
Number of Recent Samples to View
Specifies the number of recent samples that can be viewed at a given time. The minimum number you can view at a given time is 1, and the maximum is 20. When you increment this setting, the SRO generates 23 object attributes (RecentSample[n].xxx) to store information about the sample at run time.
You should increment this setting with caution because incrementing this value creates many object attributes, which take longer to deploy and load. For more information, see Sample attributes available at run time.
Specification Name
Specifies the QM specification to be used when generating on-demand samples. This attribute is used with the Generate Sample command in the Sample Data Commands pane. The QM specification specifies which characteristics should be considered in the on-demand sample, which sample plan should be used, and the sample name (as defined in the sample plan).
Sample ID
Specifies the ID (an integer) of the sample for which the data is to be recorded in the MES database.
Note: If the Sample ID is hard-coded in the Sample tab and the field is then locked, executing the Generate Sample Command will trigger a warning in the Operations Control Management Console (OCMC). The warning occurs because the command attempts to update the Sample ID field with a value generated by SQL, but cannot do so because it is locked. The associated SRO does not enter an error state and the sample is successfully generated. However, the Sample ID field is not updated with the correct value of the newly generated sample. To avoid this behavior, when configuring the SRO, avoid locking the Sample ID field. This behavior does not occur if an input source is used for the field.
Segment Requirement
Specifies the S95 segment requirement value for the sample.
Segment Response
Specifies the S95 segment response value for the sample.
Lot
Specifies the lot number for the sample.
Sublot
Specifies the sublot number for the sample.
Operator
Specifies the user/operator who pulls the sample from the production line or finalizes the sample.
Final
Specifies a Boolean value that indicates whether the sample data is final or not. After a sample is marked as final, the data and results for all the characteristics cannot be modified.
Priority
Specifies an integer value that identifies the priority for the sample.
