 Inspection Planning with Inspection Plans

Use

Inspection plans help you to describe how a quality inspection of one or several materials is to take place. In the inspection plan, you define the sequence of inspection operations and the range of specifications available for inspecting inspection characteristics.

Integration

You can integrate the following master data in your inspection plans:

  • QM-specific data

  • Other master data

  • Reference operation sets , to structure operations and inspection characteristics.

  • Work center , to define where the inspection is to take place. The work center is also used to settle appraisal costs .

  • Production resources/tools , to define the test equipment to be used. Inspection planning must ensure that the test equipment required for an inspection is available or can be obtained.

  • Change master record with which you can manage various change statuses.

  • Classes in the class system , to classify inspection plans.

  • Scheduling, to check the expected run time and modify it if necessary.

  • Material master records for the materials that are inspected with the inspection plan.

  • Vendor master records , to assign an inspection plan to a material in conjunction with a vendor.

  • Customer master records to assign an inspection plan to a material in conjunction with a customer.

  • Sampling schemes for sample determination.

  • Info records for combinations of material and vendor, or of material, customer and sales organization or purchasing data.

Features

The inspection plan has a similar structure to that of the routing. Inspection characteristics and test equipment (production resources/ tools) are assigned to one or more operations, which are in turn assigned to the inspection plan header.

Inspection specifications at inspection plan level (task list header, operation, inspection characteristic) can be overwritten by the specifications from a subordinate level.

Inspection Plan Header

The structure of the inspection plan header is similar to that of the routing. The information defined in the plan header serves as the specification for the entire plan. The following information is defined in the plan header:

  • Plan data (for example, assigned materials, task list group, group counter, plant, task list usage, plan status, planner group responsible, planning work center, validity of the plan for a certain lot-size range, old plan number).

  • Information about dynamic modification and inspection points (for example, definition of inspection points, sample-drawing procedure, dynamic modification level, dynamic modification rule, dynamic modification criteria).

  • Information about external numbering in results recording.

  • Information about engineering change management (for example, change rule, change type).

  • Administrative data (for example, change number, validity period, creator, created on, changed by, changed on and date last archived).

From the plan header, you can also enter details of material-task list assignments and a long text that describes the inspection plan.

Inspection Operation

You assign one or more inspection operations to the inspection plan header. The structure of the inspection operations is also similar to that of the operations in a routing. At the operation level, you define:

  • How the inspection is to take place

  • The work center for the inspection

  • The sequence in which the inspections are to take place

  • The test equipment (as production resources/tools) that is required for the inspection

  • Default values (such as base quantity, unit of measure, conversion of units of measure (header/operation)

  • Data for controlling results recording

  • Information about the inspection point (reference, inspection point completion)

  • Values for calculating appraisal costs

  • User-specific fields

From the operation level, you can gain an overview of any work centers, test equipment and inspection characteristics that have been assigned.

Inspection Characteristic

You can assign several inspection characteristics to each inspection operation. At inspection characteristic level, you define:

  • What is to be inspected (characteristic number, short text, long text and master inspection characteristic, if required)

  • Characteristic type (quantitative or qualitative inspection characteristic)

  • Characteristic category (required characteristic, optional characteristic, conditional characteristic)

  • Controls for results recording

  • Dependent characteristic specifications

  • Control indicators for the inspection characteristic

  • Quantitative data for the quantitative characteristic

  • Characteristic attributes (catalog type 1) for the qualitative inspection characteristic

  • Other catalogs

  • Test equipment to be used

  • Inspection methods to be used

  • Sampling procedures to be used

  • Dynamic modification rules to be used

For inspection characteristics in an operation, you define:

  • Whether a characteristic (conditional characteristic) is to be inspected, based on whether the previous characteristic has been accepted or rejected.

  • Whether the sample size for a characteristic (dependent characteristic) is to be dynamically modified using a leading characteristic.

  • Whether the system is to calculate the characteristic value for a characteristic (calculated characteristic) using data from other characteristics that have been previously valuated.
