Symptom
Generally, the characteristic's sample size should not be larger than the inspection lot quantity. Even if we use the 100% inspection, they are equal.
However, there is a requirement to make the sample size larger than the inspection lot quantity. For example, the sample size should always be "the lot quantity + 20".

Resolution
The "Additive Sample" indicator in the characteristic control indicator can be used to achieve this requirement. Here is the Help Documentation of this indicator:
Use
If you set this indicator, it causes the size of the partial sample to be increased by the quantity required for this characteristic in inspection sample calculation.
If a partial sample is to be used for several characteristics, it contains the total sample quantity required for all the characteristics.
The system calculates the sample quantity for each characteristic. For a partial sample that is used for several characteristics, the system takes the largest determined sample quantity as the partial sample quantity.
If you set the Additive sample indicator, the system does not include the sample quantity for this characteristic when calculating partial samples, but takes the next smallest sample quantity as the partial sample quantity and subsequently adds the sample quantity of the additive sample.
You can set the indicator for an additive sample, for example, if the inspection for a characteristic is destructive.
Example
I | II | III | ||
---|---|---|---|---|
Sample quantity | Additive | Additive | Additive | |
Characteristic 1 | 15 pcs | (X) | ||
Characteristic 2 | 30 pcs | X | X | |
Characteristic 3 | 20 pcs | X | ||
Total qty | 30 pcs | 50 pcs | 65 pcs |
- Example I: No indicator for additive samples is set. The system therefore determines the sample quantity for characteristic 2 as the quantity for the partial sample.
- Example II: The indicator for additive samples is set for characteristic 2. The system therefore determines the sample quantity of characteristic 3 as the quantity for the partial sample and increases this by the sample size of characteristic 2.
- Example III: The indicator for additive samples is set for characteristics 2 and 3. The system therefore determines the sample quantity of characteristic 1 as the quantity for the partial sample and increases this by the sample sizes of characteristics 2 and 3, irrespective of whether the indicator was also set for characteristic 1.
For the requirement at the beginning, for example, a dummy characteristic with sample size 20 can be created. Then if 100% inspection is used and the "Additive Sample" indicator is set, for all other characteristics, the sample size will be "the inspection lot quantity + 20".
