Dear varsha

If you wanto get the CpK, standard dev from taking the values from any Table. field it is not possible. you will have to define the formula in the program.

please find the formula in this link below

Hi,

Before executing all those transactions for getting Cpk , first of all you plan SPC for a required master inspection characteritics,

Maintain settings at MIC level, ie set indicators both SPC and sampling procedure, single value rec, record measured value, sample type

Maintain settings in sampling procedure ie choose sample type fixed sample, control chart type and valuation parameters SPC

Maintain settings in Inspection plan at operation level ie set SPC Criteria and assing sampling procedure

Hope these things would be helpful for you

Hi Varsha

Tr Codes QE13 or QE09 (Display Results). Select MIC for analysis. -> Press result History icon -> you will get new popup "Result History Limit selection" you can select history based on Material, Vendor or Time Span -> Execute

You will get result data in tabular form. Select all entries and press Histogram Icon. You will find new popup window with Histogram. There you will find tabs to get "Statistical Values", Normal distribution etc.

Alternetely you can execute report Tr Code MCXD to get Standard Deviation, CP, Cpk values

Atul.

Dear Varsha

If you want to know how to get Cpk for an MIC please follow the below

Dear Amith

one input for CP CPK you need to have single recording for the MIC. it requires some single values to be get registered before giving the Cp, CPK

1) QS28

select the MIC for which you need to get the Cp CPK > execute > select the Mic again and click on result history > a pop will appear > execute selection ( selection of vendor, bacth is available there ) select the all the lot > pop will appear with inspection lots > select all the lots below you can see various option > click on histogram and in the click on Statistics value

this works if you MIC attached to one material only

2) if you are using incomplete copy model time you can get the same

go to QA32 > put the material , plant ( combination you want) > select the lot with usage decision > execute > select any of the lot > go to results> select the mic which you need to see the values> click on result history > you will ge the pop for execution and will then get the lot list

give me ur feedback
