Incorrect capability indices and conf limits inset and/or output with LIMITS= or TABLE= in PROC SHEWHART


If a LIMITS= or TABLE= data set is input to PROC SHEWHART and any of the capability indices or their confidence limits are added to the control chart using an INSET statement, the indices and limits will all be incorrectly reported as zero or missing. The keywords on the INSET statement which generate the incorrect values are:

CP CPLCL CPUCL 
CPK CPKLCL CPKUCL
CPL CPLLCL CPLUCL
CPM CPMLCL CPMUCL
CPU CPULCL CPUUCL

When a TABLE= data is used as input, specification limits are given on the chart statement and an OUTLIMITS= data set is specified, then this same list of statistics will incorrectly be output with all missing values.

There is no circumvention for this problem.
