Dependent Multiple Samples In
Sampling Management
Applies to:
SAP QM Consultants, SAP ECC 6.0. For more information, visit the Supply Chain Management homepage.
For more information, visit the Supply Chain Management homepage.
Summary
The user wants to create multiple samples one by one manually in Result Recording Screen, when the Non
Conformity (NC) of the samples is in between allowable level and rejection level.
Each sample is interdependent and non conformities are cumulated till 7th
Sample. Once the sample is rejected,
the new sample can not be created.
Total cumulated NCs of all the seven samples are less than the rejection level, the Inspection Lot is accepted.
Total cumulated NCs of all the seven samples are equal or more than the rejection level, the Inspection Lot is
rejected.
The rejection level is indicated by  d7.

Introduction
Acceptance Number  denoted by c.
For an attributive inspection, the highest number of nonconforming units or the highest number of defects in a
sample that leads to an acceptance of the inspection lot.
Rejection Number  denoted by d.
For an attributive inspection, the lowest number of nonconforming units and/or the lowest number of defects in a
sample that result in a rejection.
Number of Non Conformity allowed in sample Number 1  c1
Number of Non conformity for rejection criteria in Sample Number 1  d1
System allows a Maximum of seven samples for any Inspection Lot.
 c1, c2, c3, c4, c5, c6 and c7 are acceptable level of seven samples.
 d1, d2, d3, d4, d5, d6 and d7 are rejection level of seven samples. Ex: Dependent multiple sample procedure
is used in Lamp Industries, for specific customer where stringent quality measures are to be adhered
In Lamp Industry, every hour 1500 to 2600 incandescent lamps are manufactured.
Similar industries, where huge quantity is produced, the dependent multiple sample procedures can be used.
Once the lot is rejected, 100 % inspection is carried out to eliminate the non conformities
Define the Requirements
Sampling Scheme
Sampling Scheme is system defined / user defined table.
This table defines the sample size for various inspection lot quantities.
For the combination of Inspection Lot quantity and Sample size, c1,d1;c2,d2;c3,d3:c4,d4;c5,d5;c6,d6; and c7,d7
are defined.
Sampling scheme  DEP  Samp.Sche. For Dependent Multiple Sample is created.
Existing sampling procedure is copied and c values and d values are modified as per requirement.

 This sampling scheme is assigned to the Sampling procedure  MULSAMPL.
 This procedure is assigned to the MIC  MULTIPLE.
 MIC is assigned to the Inspection Plan Group  241 and Counter 1.
 Material  QS8X20 is assigned to the Inspection Plan Group  241.
 QM view is created for the Material  QS8X20 and Inspection Type 01 is assigned.
Process Flow
The process flow of “Independent Multiple Samples” is given below.
In bound process is selected.
a. Sampling Scheme – DEF is created and assigned to the Sampling ProcedureMULSAMPL.
b. Material No. - QS8X20
c. Create Purchase order for the material  QS8X20  4500017450 and Vendor 1234.
d. Goods Receipt is carried out  5000002773
e. System creates Inspection Lot automatically.  Insp. Lot No.  3737
f. Sample size is 5 as the Inspection Lot Quantity is 130.
 As per sampling scheme  DEF, the sample size is 5 for the Inspection Lot quantity --. 130.
g. As per sampling scheme  DEF, seven samples are allowed.
Hence the sample quantity is 5 X 7  35.

We have selected the Inspection Lot Size as 130.
From Inspection Lot Size 91 to 150, system calculates the sample size 5 and there are 7 samples are eligible.
Hence the Sample Size is 7 X 5  35 Samples.

First Sample
C1  1 & d1  4.
c1  Allowable NC and d1  Rejection Criteria
When the NC is 1 or 2 or 3  Less than 4, the system allows to select the second sample.
FIRST SAMPLE  SAMPLE SIZE  5 AND NC  2 WHICH IS LESS THAN d1  4
Hence System allows for the second sample.
System allows to take the consecutive sample, if the non conformity does not exceed rejection criteria.
Click this  Valuate icon or F7

We get the  Valuation of Dependent Multiple Samples POPUP WINDOW.
Click this icon  Extend Sample

© 2009 SAP AG 8
We get the new screen, where we can enter the second sample results.
Second Sample
C2  2 & d2  5.
C2  Allowable NC and d2  Rejection Criteria
When cumulated NC is less than 5, System allows for the Third Sample.
If the cumulated NC is 5 or above, then System does not allow the Third sample.
Case A  Cumulated NC of First and Second Samples is less than d2,
then  System creates the Third Sample.
NC of First Sample  2
NC of Second Sample  1
Cumulating the NCs of First and Second Samples  2 + 1 = 3
 d2 = 5  3<5,
System allows to create a new sample  Third Sample is created.

After entering the results, hit the Enter Key.
We get the popup window to create the third sample.

Similarly we can proceed till 7 samples.
If total accumulated NC is less than  d7  23, the Inspection Lot is accepted.
If total accumulated NC is 23 or more than 23, the lot is rejected.

© 2009 SAP AG 11
Case B  Cumulated NC of First and Second Samples is equal or
more than d2, then  System does not allow to create the Third
Sample.
Let the NC of first sample  2
Let the NC of second sample is also  3
Cumulated NC of First and second Sample  2 + 3  5
System prevents to create a new sample.
We get the following message.
System does not create the new sample and the following message has come.
We get the following message.
 Hence the Inspection Lot is rejected.

The following table gives more clarity of this scenario.
For this Inspection Lot of lot size  130, Total Sample Size  5 X7  35.

5 SAMPLE 1 1 4 2 2
Cumulated NC is Less than d1 --> 2 < 4
 New Sample is created.
5 SAMPLE 2 2 5 1 3
5 SAMPLE 3 6 10 5 8
5 SAMPLE 4 7 15 5 13
Cumulated NC is Less than d4 --> 13 <
15  New Sample is created.
5 SAMPLE 5 8 16 1 14
5 SAMPLE 6 9 19 4 18
5 SAMPLE 7 10 23 4 22
Cumulated NC is Less than d4 --> 22 <
23 The Inspection Lot is ACCEPTED.
So in the 7th sample NC is 4  Cumulative  22, the lot is accepted.
If the 7th sample, NC is 5  Cumulative  23, the lot is rejected.
5 SAMPLE 7 10 23 5 23
Cumulated NC is Equal or More
than d4 --> 23 = 23 The
Inspection Lot is REJECTED.

Assign the Sampling Procedure to the MIC in Inspection Plan
Assign the Inspection Type to the Material  QS8X20
