Clearing one or more individual variables
1 In the Metadata Model to Quantum main window, select the variable or variables whose card, column, and punch definitions you want to clear.
2 Right-click and from the shortcut menu, choose, Clear Cols and Punches.
If any of the variables share a category list with any other variables (for example, because the variable is part of a loop or a grid or uses a defined list), this option removes the punch and column offset details from the categories on those other variables too. However, Metadata Model to Quantum will warn you first and give you an option to cancel the operation.
Metadata Model to Quantum cannot clear from a locked version of the questionnaire definition card, column, and punch definitions that were created in UNICOM Intelligence Data Model 2.4 or earlier or by older products (such as Quanquest 2.3). If old-style definitions are present in the selected variables and you are working on the most recent version, Metadata Model to Quantum will give you the option of creating a new version and entering a description for it. However, if you are using an earlier locked version, you will not be able to clear the old allocations from that version. For more information, see Clearing old-style card, column, and punch definitions.
This command does not clear the default card and column custom properties that are built-in to the system variables.
