Question:
Dear All,
My scenario is like this i have a characteristic with following possible values
1
1-2
2
2-3
3
In order to record values like 1-2 / 2-3, i have defined this characteristic as Qualitative Characteristic and linked with catalog
Now my end user requirement is that for a particular material he wants to give target value so that while recording he can know what is the standard against he is recording.
As a qualitative characteristic we can not give target value.Please guide a suitable method to come out of this issue.
Thank in advance
Best Regards,
Sridhar.
Answer:
I think in this case classed recording will help you better. You can keep the characteristic as Quantitative and instead of summarised or single unit, you can use classed recording. Here you can enter target values and also the class size and width which will allow you to record against a certain class.
For eg. you have class width as 3, class width as 1, lower and upper limit as 0.5 and 3.5
That way u can record whether your value is within, 0.5-1.5 or 1.5-2.5 or 2.5-3.5 ... something like that.

Thank u very much Tanuj for ur feed back.Actually i need to record
values like 2-3. please try to understand that the value is not 2.5.
Ther is no decimal places for the value.The value itself is 2-3.
Actually these values are the fastness values normally used in
textile processing industries.As you suggested,irrespective of classed recording system not allowing me to enter value like 2-3.
That's why i defined this characteristic as Qualitative and linked this one to a catalog inorder to record values like 1-2 or 2-3 etc.
Please suggest some other method to come out of this issue.
Best Regards,
Sridhar
Answer:
That also can be accomodated here ... bcoz u can keep the decimal places as zero ... it will take whole numbers like 2-3 ... just check the class recording indicator in yr MIC. It will ask u for quantitative data and also data for class recording. This is something that u can manipulate to record results as u want them.
Otherwise I don't believe that u can issue a target quantity for a qualitative char.

Answer:
hi
why dont you make a catalog of characterstic attribute of the tatget value ,
so when ever it is reached they will choose the catalog with target value.
however if they dont reach target value you can create a catalog as some other value which they can use.
regards
sandy
Answer:
I can't say about your scenario, but generally where catalogs are used should be data that is never changed. Because if there is a certain change in the data, then the catalog code has to be removed from all the selected sets, the catalog has to be removed from all the inspection chars that contain it, and only then can that particular entry be changed. This is a big problem.
That's why I suggested using a quantitative MIC which offers more flexibility and is less tedious to maintain.

Thank u Sandy and Tanuj.As Tanuj suggested i have created a characteristic for classed recording.But while results recording, when i am entering value 2-3 , system not allowing me to enter and giving following message.
"Value can't be interp.as floating-point number or longer than 22 charc."
Please suggest.
Best Regards,
Sridhar.
Answer:
That's not how you would enter the results ... double click on the Insp char while result recording ... then it will show u the different classes (1-2, 2-3, etc.) itself .... against that u can enter how much of the sample is present in which class.

Sorry Tanuj, actually i was on leave.I have created a characteristic with class recording with following values-
Lower limit - 1 ,upper limit - 3 ,No.of classes - 5,Class width - 2,Class mid point - 2
While results recording as u suggested,after double clicking on mic system not showing any classes.
Please suggest.
Best Regards,
Sridhar
Answer:
Is the char quantitative? Are you using summarised result recording?

Answer:
That class characteristic is not created right. With 5 classes and a class width of 2, your limits (1-3) don't allow for 5 classes. For 5 classes and a width of 2, you need limits of 0 - 10 or something like that. Seems like you would want a class width of 1 and either two or three classes. Limits would be 1-3 or 0-3.
Are these ACTUAL measurments or some relative scale that was designed for evaluating the product?

Actually these values are the ratings for washing fastness of fabric.
So normal practice is to record like : 1 / 1-2 etc.
As u asked these values are a relative scale that was designed for
evaluating the product
So please suggest what to do.

Answer:
Don't know if it is posible but since it appears to be an internally developed test, and the values appear to be relative, why not just expand the range?
Instead 1 - 3 make it 1 - 6.
1 = 1
1.5 = 2
2.0 = 3
2.5 = 4
3.0 = 5
etc..
Then make your rang 1 - 5 with an interval of 1. Might take some new training but I would think the value communicated from the value would be basically equivilent.

Thank u very much Craig.If mic is with class recording there may be a problem because if target value is 1-2,i have to give lower and upper
as 1 and 2 respectively with 5 classes,i think it is not possible.
What i feel if there is no target value better to define mic as qualitative with a selected set.If target is there better to define mic as quant. with Summ.recording,decimal places to be 1.
So that if value/target is 1-2 ,he has to enter 1.2.For this we need to train
shop floor people.
Best Regards,
Sridhar.
Answer:
If target value is 1 -2 you specify the number of 3, 4's etc.. that would make it unacceptable.
But I'm not sure that this is a good fit anyway. You do know that the target value is just that.. a target? It has no actual affect in SAP unless your using it in a subsequent calculated characteristic.
