i5SPCChart Upper Chart Specification Limits

You use these properties to configure the specification limits of the upper chart on an SAP Manufacturing Integration and Intelligence (SAP MII) statistical process control (SPC) chart.

You can specify the specification limits in the following way:

Choosing the columns (Upper Spec. Limit Column, Target Column, and Lower Spec. Limit Column) mentioned in the display object
Choosing an XML or SQL query that specifies Upper Specification Limit (USL), Target, and Lower Specification Limit (LSL) values in Specification Limit Source field. The chart uses the specific specification limit values defined in the XML query file.
Manually entering the limit values only for upper chart in the fields, Upper Spec. Limit, Target, and Lower Spec. Limit
Manually entering additional limit values in Upper Spec. Limit of Upper Chart User, Target of Upper Chart User, and Lower Spec. Limit of Upper Chart User.
You must enable Show Upper User Specification Limits and Show Upper User Target to display the user specified additional values.

The precedence of the specification limits is as follows:

If the specification limits are mentioned in all the options, then the columns chosen from the mapped query takes precedence while displaying the chart.
If you have selected limit source (XML or SQL) and manual limit values in Upper Spec. Limit, Target, and Lower Spec. Limit, the specification limits defined in the limit source are considered

Features

The following table lists the specification limit properties for the upper chart:

Property Name	Parameter Name	Data Type	Description
Upper Spec. Limit Column	`USLColumn`	String	Select a column from the drop-down list as upper specification limit.
Target Column	`TargetColumn`	String	Select a column from the drop-down list as target column
Lower Spec. Limit Column	`LSLColumn`	String	Select a column from the drop-down list as lower specification limit
Specification Limit Source	`SpecificationLimitSource`	String	You can browse and select any query template, xml or any file that specifies USL, LSL, and target. The Specification Limit Source is a query reference to the location of the specification limits for the chart template. The specification data must be returned in dataset format with the columns in the following order: effectivity date (datetime datatype), lower specification limit (LSL) (number datatype), target (number datatype), and upper specification limit (USL) (number datatype). The result set can be multiple rows. You use the effective date and the date time value of the returned data to determine which set of limits to use. For attribute SPC charts, the USL, or reject limit, is the number of rejects allowed before a lot is considered defective.
Param .[number] for Spec. Limit(For example, Param. 1 for Spec. Limit)	`SpecificationLimitParam.[number]`(For example, `SpecificationLimitParam.1`)	String	You use the specification limit parameters with the SpecificationLimitSource query. The system replaces the token values in the brackets with the name and type of the chart. The default value for Param. 1 for Spec. Limit is [CHARTNAME]. The default value for Param. 2 for Spec. Limit is [CHARTTYPE].
Upper Spec. Limit	`USL`	Floating point	Numeric value to specify the upper specification limit for the upper chart
Target	`Target`	Floating point	Numeric value to specify the target value
Lower Spec. Limit	`LSL`	Floating point	Numeric value to specify the lower specification limit
Upper Spec. Limit of Upper Chart User	`UpperUserUSL`	Floating point	Additional user value for Upper Specification Limit
Target of Upper Chart User	`UpperUserTarget`	Floating point	Additional user value for target
Lower Spec. Limit of Upper Chart User	`UpperUserLSL`	Floating point	Additional user value for Lower Specification Limit
Show Upper Specification Limits	`UpperShowSpecificationLimits`	Boolean	If this checkbox is selected, the chart displays only the upper specification limits. Some of the conditions for specification limits are as follows: If you have not defined specification limits manually or using a query, the USL, LSL, and target values are 0 and only one specification limit line is rendered on the chart. The legend is also displayed on the chart. If you have selected specification values from the columns and if you have selected Show Upper Specification Limit checkbox, the SPC engine will calculate specification limits using values from the selected columns.
Show Upper User Specification Limits	`UpperShowUserSpecificationLimits`	Boolean	If this checkbox is selected, the chart displays only the upper user specification limits.
Show Upper User Target	`UpperShowUserTarget`	Boolean	If this checkbox is selected, the chart displays only the upper user targets
Spec. Limit Color of Upper Chart	`UpperSpecificationLimitColor`	Color	Specifies the color of the specification limits in upper chart
Color of Upper Chart Target	`UpperTargetColor`	Color	Specifies the color of the target
Spec. Limit Color of Upper Chart User	`UpperUserSpecificationLimitColor`	Color	Specifies the color of the specification limits of upper chart user
Target Color of Upper Chart User	`UpperUserTargetColor`	Color	Specifies the target color of the upper chart user

You set these properties for your chart template on the Upper Chart Spec. Limits screen in the SAP MII Workbench and change the parameter values using web page scripting. For more details, see Web Page Scripting for i5SPCCharts.
