12.1 SPC Chart: Using Nelson rules instead of WECO?

Hi,
I want to apply the Nelson rules to the SPC chart instead of WECO? How and where is that configured in 12.1? (I believe it was a server level configuration in 11.5 but can't find it in 12.1 or the help).
The 12.1 help just refers to how WECO rules are applied to the SPC chart.
Thanks,
Kerby

This reference is obviously not directly MII related but does highlight some of the WECO vs. Nelson (where Nelson was an update to the original WECO) applications:

All of the alarm configurations are available to you in a common place and many have X of Y configuration options as well so you can put your own spin on the alarm criteria.

SPC Charts and Analytics

Hi....
I hope somebody can provide some help.
Does SAP's software generate SPC charts using STATIT Custom QC and STATIT eQC or another software package? or is it SAP developed?
Does anybody know if BusinessObjects is capable of generating SPC charts like an X-bar S chart? Can it also provide process capability analysis (e.g. histograms with Cpk values)?
Thanks,
John

You have to log into SAP to see the charts , cp,cpk values etc. I am not aware of any options to publish these charts on web, I never got a chance to do that.
But with my experience, the SPC options in standard SAP (ECC or R/3) are very limited not like third party applications like infinity qs etc. The SPC chart options like any other sap r/3, go to the related transaction code and pull up the charts on various selection criteria. Configurable graphical options are available and SAP supports various kinds of charts.
The other option (I have doen it in multiple places) is utilize sap to gather/collects data points, inerface third party statistical packages like statistica to sap r/3 . downlaod the data from sap and do the analysis.
Hope it helps.
Thanks,

12.1: SPC Chart - Calculate Control Limits logic/rules?

Hi,
I'm using 12.1 SP4 Patch 4 currently.
1. For SPC charts, there is a checkbox for Calculate Control Limits under the Control Limits for the Upper Chart Tab. What rules/formula does MII use for calculating the control limits? (I tried it and it looked correct but users want to verify how it calculates). See link for example: http://gunston.gmu.edu/708/XmR.asp?E=0
2. What does it do if Limits already exist for the input data set? Ignore the calculation?
3. Can this be set dynamically and refresh the SPC chart? (Set the Calculate Control Limits
UpperCalculateControlLimits Boolean property and refresh the chart? I've sometimes had issues setting these dynamic properties and having them take effect in charts so want to verify)
Thanks,
Kerby

1. I think you would already have the SPC help PDF document that has the formulas in it - Rob or Leey? In general, 3 sigma or standard deviation above and below the centerline(mean) based entirely upon the dataset returned by the underlying query template.
2. The Auto-Calc will take precedence over static limits, and the chart will use them accordingly. I'm not entirely sure, but if you look at the Summary Statistics popup from the applet you'll see EFFECTIVE and EST properties that will vary based upon the Auto Calc being enabled.
3. Yes, you should be able to 'check' the box through JavaScript and have the chart update with them. If you have issues with specific script then go ahead and post that snippet as a separate thread.

Make an XBar chart using the SPC toolkit?

Hello,
I am still learning LabView and I am wondering the best way to create an XBar chart using the SPC toolkit. Do I simply put the Xbar chart vi and the Draw Chart vi in there? Does that take every 5 data points or how does that work?
David Vaughn

Hi Dave,
It looks like the X-bar & S Chart.vi assumes that you're giving it an array where each row represents a collection of samples. Each row is averaged, and the value is plotted on the X-bar chart. I'm assuming you're going to have an array of these slope values that you eventually want to plot in an X-bar Chart. In that case, you can simply use the Build Array function to turn your 1D array of samples into a 2D array. I think you may need to use the Transpose 2D Array function to turn your 1D array into a column of values. Then wire this 2D array into the X-bar VIs and you should be set.
Now if you want to generate your X-bar chart in "real-time", i.e. you want the X-bar chart to update as your VI runs and more slope values are calculated, you should check out [labview]\examples\spc\spc_demo.llb\"Real-Time" SPC Demo. This is an example VI that shows an X-bar chart updating as values are calculated.
I hope this helps,
-D

SPC Chart and Tag Name starting with a Number

On a 11.5.3 (latest build) install, we've found that SPC Charts don't like tag names that start with numeric characters. The data points just don't plot. I can right click and get the data, but there are no points on the chart. All other applets work fine with the same tags. Has anyone else seen this?

Hey Rick,
We did try that and it worked. Also when creating the tags in the UDS Admin, I don't believe the UDS Admin will allow for this scenario (along with funky characters like pipes "|"). However, we are using an alias file (export from Historian into Excel, into SQL, and tweaked via Xacute) where the UDS Admin rules aren't enforced, which might be the inherent problem here.
I just thought that if the applets allowed it, the iSPCChart should also.
Thanks.

Value Columns - SPC chart

Hi,
i want to pass / set value columns at run time in SPC chart. i know the value column only at run time. i created one query template with giving table name and select query like select [param.1],date1 form temp1. i set attribute column of data mapping as date1. Say temp1 contains columns like Faran, temperature. i will choose any one of these column from front end. and i want to set that column name in value columns of data mapping. i tried with
document.<my applet>.getChartObject().setValueColumns("temperature"). but it displayed error as object doesnt support this property.
how to do it?
-senthil

Senthil
First get the desired column name from the Query Template which gives the column names (eg Faren, Temp etc).
say that QT name - QTTemp which is saved in some defined folder in ur system.
then
Use following
1. document.<AppletForQTTemp>.getQueryObject().setParam(1,"?"); where "?" is the input param to be passed to that QT
2. document.<AppletForQTTemp>.executeCommand();
3. document.<AppletForSPCChart>.getChartObject().setValueColumns(document.<AppletForQTTemp>.getColumnName("?")); where "?" is the column number of the desired column u want to set.

Anyone aware of SPC Charting capabilities with xCelsius?

I am very interested in being able to create SPC (Statistical Process Control) charts with xCelsius. Anyone know of an add-on? Anyone want to make an Add-on for xCelsius?
SAP Lighthammer, now SAP XII, does a great job creating SPC charts. But we want to move towards xCelsius yet SPC Charting is used heavily across all functions of the corporation.

Hi, Jeff
Check addon markeplace - https://information.ondemand.com/istore/#shopby=Marketplace/Xcelsius%20Add-Ons%20(All).
If you don't find right component, you can contact me. I can give you a contact of my friend who is Adobe Flex developer.
Maybe he will develop required component for you.

Setting LSL, USL and Target in SPC Chart

I need to set my LSL, Target and USL of an SPC Chart to nothing. Is the below param correct to do this? I have tried this and it seems to set them at 0. This then throws my chart off as far as SPC control limits goes. I can not simply open display editor and change this because more than one chart depends on this display.
<param name="USLColumn" value="">
<param name="LSLColumn" value="">
<param name="TargetColumn" value="">

Why do you need to set them to "nothing" - shouldn't you be using another type of chart (e.g. custom chart, line/marker chart, etc.)?
In any case, simply deselect showing the LSL/Target/USL in the display template editor.
<param name="UpperShowSpecificationLimits" value="false">
<param name="LowerShowSpecificationLimits" value="false">

Combining USL and LSL on SPC Chart and showing as USL/LSL

Hi All,
I am willing to change the wording on the Legend for SPC chart. As USL and LSL both hold same colour on the chart. I would like to show it as USL/LSL instead of two separate strings on Legend followed by colour. Can it be done....?
Regards,
Ravi Kumar

No. It is better to train the users
Another option would be to turn off the legend and create your own 'legend' with a small html table.

Dynamically displaying SPC Chart Title

Hi
I have created SPC Chart Disply.I did dynamic change of chart types(like xbar,xbar-range). Now i want to reset the Chart title property dynamically. if any methods available.
Thanks in advance.
Regards,
Malini.V

This method and all of the other helpful get/set syntax methods are easy found by using the Script Assistant, which is part of the Productivity Tool installation that you can add to your client workstation by running the Wizard Install link found in the xMII Menu's Visualization Services section.
If you are working on a dynamic SPC charting application you might also be able to learn from some pre-installed content: http://localhost/Lighthammer/Samples/SPC/Servers.irpt

Viewing SPC chart - how?

Hi
I am quite new with MII. I am experimenting the SPC example from the QualityPortal and I do have connection to the SQL server and the QualityPortal project also successfully imported. I could also see the template loaded in Workbench.
However how do I view the SPC chart (applet)?. What I did was in IE, i entered
http://<server>:<port>/XMII/SPCChartServlet?DisplayTemplate=QualityPortal (ofcourse the actual server and port name). However I got this error message
"Template was not found, cannot load QualityPortal"
any suggestion? thanks in advance
seng

Hi,
Did you check that display templete is avaialble in the project root folder.
Also I think you havenot passed the qurey template to the display template.Just map the query template(from data mapping tab) to the SPC Chart display template.Then go for executing this display template in workbench.
You can also use Dynamic Page Generator for viewing the chart.

SPC Chart Display

Hi honored experts,
I am trying to set up some demo SPC charts for a customer with no success...
What I did so far:
1. I defined a DC group with two parameters.
2. I entered a few figures for those parameters for some PSNs using the standard POD.
3. I defined a SPC chart with some random values using the SPC CHART MAINTENANCE activity.
4. I launched the SPC Display activity and entered the DC Group and one of the Parameters which I defined under (1).
5. When I hit the "search" button I get the message "No charts defined for combination of DC group "P-109", version "A" and DC parameter "DREHMOMENT" (Message 19660)"
So, what's wrong?
I count on you...
best wishes,
Georg

Hi Sergiy,
my initial question is solved. Now the system asks me to install the Statit e-Server... I will see how that goes... maybe I'll come back with some more questions...
Nevertheless, this thread is closed. Thanks.

SPC Chart function setPropertyValue("ShowXAxis") broken?

Hi,
Using 12.1 SP6 but have the same problem in SP4.
I have an SPC chart being plotted for a variable amount of data. If there are less than ~75 batches I want to show the X axis with the batch numbers, if I have more than 75 batches I want to disable the X axis because the x axis label runs together and is completely unreadable.
I tried dynamically setting the boolean for ShowXAxis in the irpt page and it took no effect. Is this functionality broken or is something wrong with the syntax? It didn't throw any errors when I tried it...
The exact command used was document.SPCChart.setPropertyValue("ShowXAxis",false);
Additionally, starting in SP6 if I change a parameter in a display template in the workbench and save the template and reload the page then the saved change does not take effect. In SP4 all that was needed was to reload the page but in SP6 I seem to need to clear my java cache before a change to a display template takes effect. I'm not sure how dynamic setting of display template property values will work if this is the case?
Any options here?
Thanks,
Kerby

It would appear you're not using the script assistant, which would help eliminate guessing.
document.SPCChart.getChartObject().setShowXAxis(false);
document.SPCChart.updateChart(false);
The setPropertyValue method you tried would normally be used to add a name/value pair to the user session - not directly effect a runtime setting in either the query template or display template.

Pie chart using Class cl_igs_chart ??

Hi All,
I am looking for Sample code, how to draw Pie chart using standard class: cl_igs_chart.
I found a Standard SAP prog: GRAPHICS_IGS_CHART_TEST for drawing Bar chart, looking for pie chart now?
Please help me!!
Thanks in advance.

Hi,
if you want to create charts in the background using the IGS is the right choice!
Let's have a look at cl_igs_chart:
creating a pie chart can be done easily by changing the demo report graphics_igs_chart_test; just change the line
igs_chart->type = cl_igs_chart=>co_type_bars.
by replacing co_type_bars with co_type_pie (check the attributes of cl_igs_chart to see a list of chart types).
However, as cl_igs_chart does not provide further customizing settings I recommend that you download the SAP Chart Designer (as mentioned above) and use the class cl_igs_chart_engine instead. Demo report is graphics_igs_ce_test.

How do we use Data rules/error table for source validation?

How do we use Data rules/error table for source validation?
We are using OWB repository 10.2.0.3.0 and OWB client 10.2.0.3.33. The Oracle version is 10 G (10.2.0.3.0). OWB is installed on Linux.
I reviewed the posting
Re: Using Data Rules
Thanks for this forum.
I want to apply data rules to source table/view and rule violated rows should go to defined error table. Here is an example.
Table ProjectA
Pro_ID Number(10)
Project_name Varchar(50)
Pro_date Date
As per above posting, I created the table in object editor, created the data rule
NAME_NOT_NULL (ie project name not null). I specified the shadow table name as ProjectA_ERR
In mapping editor, I have projectA as source. I did not find error table name and defined data rules in table properties. It is not showing up the ERR group in source table
How do we bring the defined data rules and error table into mapping?
Are there any additional steps/process?
Any idea ?
Thanks in advance.
RI

Hi,
Thanks for your reply/pointer. I reviewed the blog. It is interesting.
What is the version of OWB used in this blog?
After defining data rule/shadow table, I deployed the table via CC. It created a error table and created the all the source coulmns in alphabatical order. If I have the primary key as 1st coulmn (which does not start with 'A') in my source, it will apprear middle of of columns in error table.
How do we prevent/workaround this?
If I have source(view) in sch A, how do we create Error table in Sch B for source(view)?
Is it feasible?
I brought the error table details in mapping. Configured the data rules/error tables.
If I picked up 'MOVE TO ERROR' option, I am getting "VLD-2802 Missing delete matching criteria in table. the condition is needed because the operator contain at least one data rule with a MOVE TO ERROR action"
On condition Loading - I have 'All constraints' for matching criteria.
I changed to "no constraints' still I get the above error.
If I change to 'REPORT' option instead of 'MOVE TO ERROR' option, error goes off.
Any idea?
Thanks in advance.
