Dear all
May any body help me to explain control chart.Can we assign it only on Quantitaive characteristics or also on Qualitative.and what we need for developing a control chart.
Please explain in detail.
You can only do this on quantitative characteristicc. It would make no sense on qualitative charac.
In the MIC control indicators you must mark the chara as SPC characteristic. You must select sampling procedure.
You must create a sampling procedure and when creating it, specify it is to be used for SPC and select the type of SPC chart you want.
That's the basics.

Dear craig
thanks for replying
I have created a sampling procedure with fixed sampling 1 and Shewart chart X bar.
Created an insp. characteristic.
In the routing i assigned that characteristic on an operation and assigned that sampling procedure to it.
Now i have recorded many results in the QE71 for different identifications.and saved.
Now from where i can see the control chart for that characteristic.
Pretty hard to guide you on that. I've never been very good with the SPC stuff... But basically the message is telling you that for the chart you selected, there isn't info for it. So select a different chart, or review the help infor for the functional module related to the chart you did select, (can be found in config), and have a statistican help explain what data your missing to complete the chart.
