I have recently become a team leader of a SAP R/3 Release 4.6D Implementation on the QM Module.

I am currently trying to set up quality scores for various usage decisions and was wondering what views there are as to the acceptance reange of a vendor maybe i.e. 80 or below a block maybe required.

Any help appreciated

I presume you are looking at possibilities to automatically control the stock posting depending on the UD score.

While creating the selected set codes, you have the field "Posting proposal for UD", which can be selected depending on the score you have defined. Like for a score less than 80, you could choose "blocked stock" etc. This would also mean that you have to select the background processing indicator (Automatic Posting) for the above to take place.

That's exactly what I'm trying to do , I've managed to set up the UDs and put some bogus quality scores in for now. what i'm really after is a clue to the figures used. So that I can use them as a starting block.

Also does SAP have a set limit ie score of 80 is poor ??

Thanks for the input,

I've set up various acceptance decisions and want to give scores to them which will affect the overall score of a vendor. I think your right and it needs to be business specific.

thanks

You may go through these detailed notes supplied by SAP which give an insight on how to define your quality score with examples.

I had sent it as an attachment. I am sending it again without attachment.

The quality score procedure is defined in the inspection setup for the material master at plant level. You can define a default value for this procedure in the inspection type.

Requirements
o   If you want to use quality score procedures that access the weighted shares of defects for the characteristics, you must maintain the characteristic weights.
o   If you want to use quality score procedures that access the quality score of the characteristics, you must maintain the defect classes.
o   If you want to use quality score procedures, in which the system calculates the share of scrap, you must:
-   Check whether procedures for estimating the scrap share have been defined in Customizing
-   Assign suitable procedures for estimating the scrap share to the characteristics in the task list
-   Identify inspection characteristics as relevant for scrap in their control indicators

Standard Settings
A number of commonly used procedures for determining the quality score are implemented in the standard system:

o   Quality score from the usage decision
o   Quality score from the share of defects in the lot
o   Quality score from the shares of defects for the characteristics
-   From the maximum share of defects
-   From the weighted average share of defects
o   Quality score from the quality score of the characteristics
-   From the minimum (worst) quality score
-   From the weighted average quality score

SAP Recommendation
o   Use the procedure in the standard system.
o   Decide on certain procedures for each inspection type; if possible, do not differentiate according to material groups or plants.

Activities
1.  Determine which procedures for calculating the quality score should be used. You can make a distinction on the basis of the:
-   Plant
-   Inspection type
2.  Modify the table of quality score procedures according to your needs. If the procedures contained in the standard system are not sufficient, you must create additional procedures using function modules.
3.  Define the quality score procedures in the Default values for the inspection type or in the inspection setup for the material.

Further Notes

Example for representing the quality score procedure according to VDA-1
(VDA = Association of German automobile manufacturers).

According to VDA-1 the best quality score = 100, the worst = 1.
In this industry sector, the vendors are divided into three classes:

a) Quality score >= 96
b) Quality score >= 90 and < 96
c) Quality score < 90

The formula for calculating the quality score is: QS = 101 - (1 * A1 + 5 * A2 + 30 * A3 + 100 * A4): A5

A list of the characters and their meanings follows:

-   A1 = Number of goods receipts without defects
-   A2 = Number of goods receipts with minor defects
-   A3 = Number of goods receipts with major defects
-   A4 = Number of goods receipts with critical defects
-   A5 = Total number of goods receipts

To reproduce the procedure in the system according to VDA-1, proceed as follows:

1.  Define defect classes with the following quality scores:
    a) Critical defect with quality score = 101-100 = 1
    b) Major defect with quality score = 101-30 = 71
    c) Minor defect with quality score = 101-5 = 96

2.  Assign these defect classes to the codes defined in the defect catalog.

3.  Define defect codes in the task list characteristics in case a characteristic is rejected.

4.  Choose the procedure contained in the standard system that determines the quality score using the minimal quality scores from all inspection characteristics.

In this way, an inspection lot with no defects receives a quality score of 100, an inspection lot with minor defects receives a quality score of 96, an inspection lot with major defects receives a score of 71 and an inspection lot with critical defects receives a score of 1. On this basis you can classify vendors according to VDA-1 in the QM info system, if you have
predefined the corresponding class limits in the info system.
