Add Variable

Overview

The process to add a variable to a mix design is available through the Variables Tab of the Mix Design Details Tab. The process is identical to adding a variable to a mix design template.

 

Prerequisites

• A mix design must have been added.

• A test must have been associated with the selected mix design.

 

Add Variable

To add a variable to a mix design:

• Search for and select a mix design from the drop-down menu.

• Navigate to the Variables Tab.

• Click on the Add Button above the Variables Tab.

  OR

• Right click anywhere in the Variables table.

• Select "Add" in the context-sensitive menu.

• The Add Variable Window will appear.

  

  • Search for and select a variable from the Name drop-down menu.

  • Check the "Retrieve value from executed sample" box if desired. This will automatically populate the Value field with information from an executed sample test. Select a Test, Test Question, and Sample from the drop-down menus.

  • Check the "Retrieve value from attached test" box if desired. This will automatically populate the Value field with information from a test attached to a mix design through the Mix Design Tests Tab. Select a Test and Test Question from the drop-down menus.

  • Enter a value manually in the Value field, if necessary.

  • Edit other information including checking boxes to indicate if the variable will be required or included in printed reports.

  • Click on the Save Button.

• Note that a new variable is added to the Variables table.

 

Notes

• Administrators can manage the list of available variable names in the Codes Window. The master list of variable names available for use in mix designs is "Aggregate Batch Variable."

• Users are prevented from saving changes to a system item to which changes have already been made. This prevents concurrency errors.
