Master data set-up for inspections

The master data set-up is used to create a standard test procedure, that is a Test Plan used for an item or a group of items. A standard test procedure consists of a combination of one or more characteristics (a specific quality (like weight, length) that must be tested/ measured) and the tests that must be executed to determine the quality. The quality of an item can be inspected using various procedures: selling an item (Sales (SLS)), purchasing (Purchase (PUR)), producing (Routing (TI)), releasing a produced item to a warehouse (Production (JSC)), and transferring from one warehouse to another. Effectively, for an item, more than one standard test procedure can be defined because different characteristics are relevant for different procedures.

In the Master Data you can enter data such as:

  • Standard test procedure: A link between the item that must be inspected and the master data that determines what is tested for an item.
  • Testing combinations: The conditions that determine the generation of inspection orders, and how the inspections are carried out.
Define the characteristic(s)

A characteristic is a reference to a particular quality or distinctive mark of an item or an item part/component. For example, diameter, length, weight. A characteristic determines what features or properties of an item must be tested.

Use the Characteristics (qmptc0101m000) session to define the characteristic(s) of a product.

You must specify the following:

  • Characteristic Type
    • Fraction: A number with decimals, for example, 3.145.
    • Integer: An exact whole number as opposed to a number with decimals, for example, 1, 2, or 3.
    • Option: Values (options) for a characteristic that must be defined (for example, blue or red).

You must specify the following:

  • Method
    • Algorithm: The characteristic value is calculated by means of an algorithm, using the inspection results of variable or fixed characteristics.
    • Fixed: The characteristic value is determined once and can be entered in the Fixed Characteristic Value field in the Standard Test Procedure Characteristics (qmptc0115m000) session. LN uses this value to compare with the results entered in the Inspection Order Test Data (qmptc1115m000) session.
    • Variable: The characteristic value is measured immediately by means of an instrument. The results are entered in the Inspection Order Test Data (qmptc1115m000) session or the Inspection Order Lots / Serials / Stock Point Details (qmptc1131m000) session.
Define an aspect and link characteristic.

Aspects are used to reflect the various parts of an item for which the same characteristic is used. By means of which the same characteristic can be used more than once for the same item. For example, cylindrical shape.

Use Aspects (qmptc0102m000) session to define an aspect and Aspect (qmptc0602m000) or Aspect-Characteristics (qmptc0103m000) session to link characteristic.

Example

A bolt can have aspects head and tail. An aspect can have one or more characteristics.

A head can have a diameter and a length, and a tail can have a diameter and a color.

Define algorithm variables and link it to an algorithm

An Algorithm is a formula used to calculate the results of a test and determine whether or not the item is acceptable. Often other characteristics are measured and used to calculate the value of the characteristic with the method Algorithm.

  • Define an algorithm in the Algorithms (qmptc0121m000) session.
  • If you have not defined any variables, define the variables of the expression in the Algorithm Variables (qmptc0123m000) session.
  • Link the variables to the algorithm in the Algorithm Variables (qmptc0122m000) session.
  • Select the algorithm to which you want to link an expression in the Algorithms (qmptc0121m000) session, and fill out the Expression field.
Define the test(s)

A test is an inspection of the characteristics. You can link one or more tests to a characteristic.

Use the Tests (qmptc0106m000) session to define the tests. An examination or check done on a characteristic.

Define the instruments and test areas

Tool that is used during quality tests to measure particular characteristics of an item. Test area is the location where a product is inspected. A test area can be a work center, a warehouse, or an inventory location in a warehouse.

Use the Instruments (qmptc0108m000) session to define a tool that is used during quality tests to measure particular characteristics of an item. Use Test Areas (qmptc0107m000) to define the physical location where tests take place.

Link the tests and characteristics in the Characteristic Tests (qmptc0105m000) session. Specify the result type (Quantitative or Qualitative) and instruments to execute the tests.

Define code letter tables

Use the Code Letter Tables (qmptc0161m000) session to create and maintain code letter tables. You can link the tables to the inspection level and the letters. Letters are used to determine the various code letters that are applicable for a sampling rule.

Define inspection levels

Define the level at which inspections must be conducted. Use the Inspection Levels (qmptc0164m000) session to define inspection level.

Define inspection standard

Define standards (For example, ISO, DIN, MIL and so on) used to test one or more characteristics of a product, and determine if conformity is achieved for each characteristic. Use the Inspection Standards (qmptc0174m000) session to create inspection standards applicable for the sampling plan and sampling rule.

Define sampling plan

Sampling plan is used to define, sample (quantity or size) to be tested, inspection standard, the severity of the inspection, the acceptable quality level and sampling plan matrix. Use the Sampling Plan (qmptc0670m000) session to create a sampling plan.

Define sampling rules

Sampling rules that are based on sampling plans. The rules define how and when samples are taken and the sample and accept/reject criteria. Use the Sampling Rules (qmptc0160m000) session to define sampling rule that are used for a standard test procedure.

Define test procedures

A Standard Test Procedure is a grouping of quality standards and tests. The data included in a particular Standard Test Procedure includes all guidelines relative to extracting samples, performing tests and comparing the test results to acceptable limits for the specified characteristics.

Use the Standard Test Procedures (qmptc0110m000) session to define test procedures. You must specify the effective and expiry date of the standard test procedure.

Link the characteristic, test group, and test group characteristics. Use the Standard Test Procedure (qmptc0110m100) session to link the characteristic, test group, test group characteristics, where-used standard test procedure to the defined standard test procedure.

  • Use the Standard Test Procedure Characteristics (qmptc0115m000) to link multiple characteristics or aspect/characteristics combinations to a standard test procedure. You can add properties for a standard test procedure like test, norm, limits method, and effective date. You must define the upper and lower limits and tolerance data for the tests attached to the aspect/ characteristic combinations that are linked to a standard test procedure.
  • Use the Test Groups (qmptc0136m000) session to link the test group to the specified standard test procedure. You must select method by which the samples are taken from the order quantity.
    • 100 : All items are inspected. The sample size and the order quantity have the same value.
    • Single Sampling: One sample out of the entire order quantity is inspected.
    • Continuous Sampling: This type of sampling only takes place in case of mass production and is used to control processing.
    • Sampling Rule: A specific rule that states how and when a sample must be taken and the related inspection standard.
  • Use the Test Group Characteristics (qmptc0137m000) session to link groups of characteristics to a test group. Specify the sequence in which the characteristics are tested.
Define testing combinations

Testing combinations define what, when, and how inspections are to be carried out. Testing combinations link an origin, an item or quality group, and a standard test procedure.

Use the Testing Combinations (qmptc0119m000) session to define testing combinations which, comprises of:

  • The origin of the inspections.
  • The item or quality group that applies to the combination.
  • The quality ID that applies to the combination.
