Below we explain how to configure the quality check for dynamic calculations.

p_rep_0086

First, display the data source selection dialog from the point registration on the daily report screen.

p_rep_0089

Select "Specify Expression" in the data source options and define the calculation expression.

If you want to treat undefined values as 0 when performing calculations, check the following box.

p_rep_0092

If you do not check "Calculate assuming undefined values as 0", the calculation result will be a null value (NULL value) if there is a null value (NULL value) in the calculation data, regardless of the quality check settings described below.

p_rep_0090

To set up the quality check, click the selection button on the left.

p_rep_0091

The setting dialog shown on the left will then be displayed. Select the desired setting from the setting dialog.

Once you have completed the settings, click the OK button.

The quality checks for each setting are as follows:In addition, if you do not check "Calculate assuming undefined values as 0" on the data source selection screen, the calculation result will be a null value (NULL value) if there is a null value (NULL value) in the calculation data, regardless of the settings below..

Quality check follows default			It follows the default setting defined by the ActiveExpressionQualityCheckType parameter in the Summary Master common properties section. For details on the Summary Master settings, see "Common Properties Section".
No quality check			This calculation does not perform any quality checks.
Conduct a quality check	When there is a null value in the calculation data	Calculate as is	If the "Calculate assuming undefined values as 0" check box is checked on the data source selection screen, undefined values will be calculated as 0.
		The result is null	If there is a NULL value in the operation data, it will be treated as a NULL value.
		The result is an unconfidence value (e.g. *123).	If a NULL value is present in the calculation data, it will be treated as an unreliable value (such as *123).
	When unreliable values (such as *123) are present in the calculation data	Calculate as is	The calculation is performed directly based on the unreliable value.
		The result is null	If the calculation data contains unreliable values (such as *123), the value will be set to NULL.
		The result is an unconfidence value (e.g. *123).	If unreliable values (such as 123) are present in the calculated data, they will be treated as unreliable values (such as 123).
