Consistency Check for Inspection Plans (SAP Library

Consistency Check for Inspection Plans

Use

If you create or change an inspection plan, the system cannot automatically check all dependencies between:

Inspection plan headers and inspection characteristics
Operations and inspection characteristics
Different inspection characteristics
Dependent characteristic specifications and inspection characteristics
Dependent characteristic specifications and production resources/tools
Dependent characteristic specifications and material/task list assignments

As a result, when you are creating or editing an inspection plan, inconsistencies can occur. Such inconsistencies can in certain circumstances only be removed at a later date, once the production sequence is fixed. For this reason, you can specify when certain consistency checks are to be performed.

Prerequisites

In Customizing , the Cons. chk. consistency check indicator must be set in status management, if the inspection plan consistency is to be checked automatically before saving. If this indicator is not set, you can only carry out a consistency check if you call the corresponding function directly from the inspection planning functions.

Features

The system makes a consistency check for the entire task list group. The check is made not only for the key date, but for the entire validity period of the change status you have called up.

During the inspection plan check, the system checks the consistency of the following elements:

Entire Inspection Plan

The system checks the consistency of the entire inspection plan, when you exit the inspection planning function or when you choose the consistency check pushbutton in inspection planning. Examples of inconsistencies:

The indicator for inspection characteristics is set in the control key of an operation; however, no inspection characteristics exist for this operation.
The indicator for inspection characteristics is not set in the control key of an operation; however, inspection characteristics exist for this operation.
No inspection point type has been entered in the chosen sampling procedure, although the inspection plan specifies an inspection with inspection points.
Inspection points have been entered in the inspection plan header, although neither time nor quantity has been specified in the inspection operation.
Results recording by unit to be inspected has been defined in the inspection operation. No inspection characteristics with single-value recording or without dependent multiple samples have been included in the inspection plan.
The unit of measure for the sample cannot be converted into the base unit of measure for the material.

Note

The system checks the consistency of an inspection plan from the key date that was specified on the initial screen. The system proposes the current date as a default value for the key date. If you want the consistency check to be carried out for a period of time prior to the current date, you must call the transaction again and change the key date accordingly.

Inspection Characteristics

The consistency of the inspection characteristics is checked automatically, when you exit the characteristic overview. This check takes place, irrespective of whether the consistency check indicator is set in Customizing. Examples of inconsistencies:

The formula is incorrect. As a result, automatic value calculation is not possible.
Calculated characteristics reference invalid characteristics.
There is no required characteristic as a leading characteristic for at least one conditional characteristic.
Leading characteristics are assigned to other leading characteristics.
The inspection characteristic references a production resource/tool that has been deleted in the meantime.
The dynamic modification criteria defined at inspection characteristic level cannot be used for the chosen inspection plan usage.
A master inspection characteristic or class characteristic appears repeatedly.
Sample processing using inspection points has been defined in the inspection plan header. As a result, the long text for the sample-drawing procedure is overridden by the text from the inspection plan header, or the units of measure for the sample and partial samples do not correspond.

Dependent Characteristic Specifications

Examples of inconsistencies:

Dependent characteristic specifications reference invalid material/task list assignments
Data from dependent characteristic specifications are inconsistent with control indicators from the inspection characteristics.
The assigned production resource/tool was deleted in the meantime.

If the system finds inconsistencies, it displays information, warning or error messages in the message log. If the system displays a warning message, you can still save the plan without correcting the inconsistency. However, if it displays an error message, you must correct the inconsistencies before you can save the plan.

Activities

Automatic Consistency Check

In Customizing, you set the Cons. chk. indicator.

Before saving, the system checks the consistency of the inspection plan. The consistency of the inspection characteristics is also checked, when you exit the characteristic overview.

If the system finds inconsistencies, it displays warning or error messages in the message log.

Manual Consistency Check

On the operation overview screen, or in the inspection characteristic overview, choose Check task list.

The system checks the consistency of the inspection plan and records any generated messages in a consistency log.

To display the list of messages choose Extras ® Task list check ® Consistency log.
