You set this indicator for inspection characteristics whose samples will be destroyed when you inspect the characteristics.
When you make the usage decision, the system calculates the quantity of materials destroyed and makes a proposal for the stock posting to sample usage.
The system takes all inspection characteristics into consideration corresponding to the actual sample size for which the indicator Destructive insp. is set and for which inspection results have been recorded (up to the point of the calculation). This may include optional characteristics, skipped characteristics, long-term characteristics, and unplanned characteristics. For the stock posting, the system proposes only the part of the destroyed quantity that exceeds the amount already posted to sample usage.
For example, you set the indicator for an additive sample if the inspection of an inspection characteristic is destructive. In this case, the indicator causes the sample quantity to be increased by the amount needed to inspect this characteristic.
If you inspect only one inspection characteristic destructively and you inspect this characteristic last, you should not set the indicator Additive sample for the characteristic.
You must set the indicator Additive sample if you inspect more than one inspection characteristic destructively and if you can only inspect one of these characteristics for a partial sample.
If several characteristics contribute to the destruction of the sample, you can combine these characteristics for a partial sample.
A simple example without physical samples
Four characteristics are inspected. The inspection of characteristics 1, 3, and
4 are destructive. The indicator Additive sample was set for characteristic 4.
Characteristics Destructive Additive To be Inspect Inspected
1 x 10 * 1 pc 5 * 1 pc
2 10 * 1 pc 10 * 1 pc
3 x 10 * 1 pc 10 * 1 pc
4 x x 4 * 12 pc 5 * 12 pc
In calculating the destroyed quantity, the system only considers the actual inspected sample size specified in results recording (“Inspected” column) and not the sample quantity to be inspected specified in the inspection instruction (“To be inspected” column).
When you make the usage decision, the system determines a destroyed quantity of 70 pieces and proposes they be posted to sample usage. Characteristics 1 and 3 are combined, since they are not marked as additive.
Extended example with physical samples, long-term characteristics, and different units of measure
The unit of measure for the lot is PIECES; the following conversion factors are stored in the material master record:
* 4 pieces = 3 l
* 8 pieces = 9 kg
In the inspection plan, it is defined that characteristics 1, 3, 4, and 6 (physical sample 100) are to be inspected in laboratory 1 and characteristics 2, 5, and 7 in laboratory 2 (physical sample 200).
Characteristics Phys. Sample Destructive Additive Inspected
1 100 x x 5 * 100 ml
2 200 x 1 * 1 kg
3 100 x x 5 * 100 ml
4 100 x x 4 * 100 ml
5 200 x 4 * 1 kg
6 100 x x —-
7 200 x —-
After inspecting characteristics 1 through 5, the destructive quantity consists of 1400 ml and 4 kg, which is rounded off to 6 pieces. When you make the usage decision, the system proposes that 6 pieces be posted to sample usage.
You then record the results for long-term characteristics 6 and 7 and change the usage decision.
Characteristics Phys.Sample Destructive Additive Inspected
6 100 x x 8 * 100 ml
7 200 x 2 * 1 kg
The destroyed quantity now consists of 2200 ml and 4 kg, which is rounded off to 7 pieces.
When you make the usage decision, the system proposes 1 piece to be posted to sample usage, since 6 pieces have already been posted to sample usage.
You can use user exit QEVA0009 to individually calculate and predefine the quantity to be posted to sample usage.
Not all the components are scrapped but certain are, in that semi finished product if that is the case, enter them as unplanned by-products and post to inventory using MB11. Use this as a component in the next production run.
This is how we can map easily the destructive testing in multiple operations.
