Examples of Inspection Levels
You can define levels based on factors such as frequency of checks, complexity, item value, credibility of the supplier, acceptance history, and so on.
Scenario
For example, you can have three different levels: reduced, normal, and tightened inspection levels:
-
Reduced inspection level: where fewer samples are required and less often, due to high level of confidence.
-
Normal inspection level: will be the default inspection level, which will be widely used.
-
Tightened inspection level: where more samples are required and more often, due to problematic suppliers or high value items.
Inspection Levels ensures adherence to the quality standards and helps you make informed acceptance decisions.
Skip Lot Enabled: You can control the frequency of inspection based on the lots to be inspected out of the total lots received. For example, you can choose to inspect one out of every five receipt lines.
Sampling Enabled: You can choose the sampling plan type as one of these
-
Percentage
-
Fixed Count
-
ANSI/ASQC Z1.4 Standard
Quantity Per Sample: You can specify the amount of material required to perform all tests against a single sample, including a sample quantity unit of measure.
Example for Percentage sampling plan type
Let's consider a scenario where inspection level is defined for 2% sampling. If 1000 units are received, then 20 samples are inspected.
Example for Fixed Count sampling plan type
Let's consider a scenario where inspection level is defined as fixed count 10. If 1000 units are received, then only 10 samples are inspected.
Example for ANSI/ASQC Z1.4 Standard sampling plan type
When defining an inspection level, you can select the following information as part of an acceptable quality limit sampling plan:
-
Select a predefined ANSI standard as the sampling plan type
-
Choose the sampling code and level
-
Specify the acceptable quality limit which is the percentage of the sample that can be rejected while still accepting the sample
For example, if you receive 20 each for quality inspection, have a single sampling plan for normal inspection with general inspection level II, and have an acceptable quality limit of 2.5, the sample size is 5 each. The number of rejected units must be equal to or less than the acceptance number of zero to accept the receipt line quantity. If the rejected units are equal to or greater than the rejection number of one, the receipt line quantity is rejected.
Example for the Quantity per Sample and Sample Quantity UOM
Let's consider a scenario where you must collect half liter per sample against a mixing task in a process manufacturing work order, where the production is measured in gallons. To enable this sampling setup, define an inspection level with the Quantity per Sample value set to 0.5 and the Sample Quantity UOM set to Liter. If you have used this inspection level in an inspection plan, and that plan is used for ad hoc WIP inspection, both quantity per sample and total quantity values are displayed while creating the inspection. The total sample quantity is displayed both in the transaction UOM and sample quantity UOM. You can also view these details on the Inspection Details page.
