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.

The Specification Limit Sourceis 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.

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]. For more information, see iSPCChart Chart Area Properties.

You set these properties for your chart template on the Upper Chart S pec. Limitsscreen in the SAP MII Workbench and change the parameter values for individual applets using scripting.
