Define Control Plan Lines
Explanation
Each control plan manufacturing, control plan purchasing or control plan inventory consists of two levels: a
header and one or more control plan lines. This activity is used to create new control plan lines.
A control plan line for a manufacturing control plan specifies how to inspect a specified part during the
execution of a shop order. You can inspect not only the main product of the shop order but also its co-products,
by-products, and disassembly components.
A control plan line for a purchasing control plan specifies how to inspect a purchased part when purchased from
the supplier entered in the control plan header.
A control plan line for an inventory control plan specifies how to inspect a part when performing analysis in
inventory.
For each control plan line, the sample size will be calculated when an analysis is created. To calculate the
sample size, an inspection code must be selected. The inspection type specifies whether the sample size is
based on a fixed quantity or a sample percentage of the order size. It is not possible to use
Percentage as the inspection type if the part is used as a production schedule part.
For acceptance sampling, a system-generated inspection code ‘ACCEPTANCE SAMPLING’ is used, which has
a sample percentage of 100%. The actual sample size will be calculated by the system when the analysis is created.
A control plan line using the inspection code for acceptance sampling will be automatically connected to an
acceptance sampling trigger.
To create a new control plan line (data point), click the new command on the Control Plan
Lines tab;
- In the Data Type field select Attributes, Variable or
Categorical.
- If the data type is set to Categorical, enter a Category ID or use the List
of Values (LoV) picker to choose from the available category IDs in the Category field. Select a
Category Entry type to define how to enter inspection results for the categorical data
point.
- If the data type is set to Variable, enter information about the tolerance limits in the
Outer Min, Inner Min, Nominal Value, Inner Max and Outer Max fields. The
nominal value is required, along with either the combination of Inner Min/Inner Max and/or
Outer Min/Outer Max.
- In control plan manufacturing it is mandatory to enter a part in the Produced Part to
Inspect field for each control plan line. Use the List of Values to choose from the available parts. Any
produced part (by-products, co-products, or disassembly components) that exists in at least one of the existing
product structure alternates for the main product part, defined in the header section of the control plan, may be
selected.
- If the Serial Registration option is enabled, registration of serial numbers will be
enforced when entering inspection results for the data point. This option is only available in control plan
manufacturing if the Produced Part to Inspect is serial tracked and Data Type
is Variable or Categorical. The Serial Registration option is
not available in control plan purchasing and control plan inventory.
- To make it mandatory to attach a media item to the inspection result, enable Media
Required.
- To activate acceptance sampling for a control plan line, select the system-defined Inspection
Code ‘ACCEPTANCE SAMPLING’. When activating acceptance sampling for a control plan line, the
AQL and Inspection Level values will automatically be set to the default values
defined in the Acceptance Sampling Parameters section in the control plan header, but
they can be edited. If acceptance sampling is activated for a control plan line with data type
Variable, it is also mandatory to set Specification Limits and Standard
Deviation values.
Prerequisites
- The control plan header must be in the status Created.
- At least one norm type must have been created.
- At least one inspection code must have been defined.
System Effects
As a result of this activity, one or more control plan lines will be created. The inspection code selected in
the control plan line will control the sample size for each data point when the analyses are created.
