Assignment of Dependent Characteristic Specifications (SAP Library - Inspection Planning with the Engineering Workbench)

Assignment of Dependent Characteristic Specifications

Use

For both qualitative and quantitative characteristics you can define dependent characteristic specifications, based on a combination of material, vendor, and customer, if these combinations have been assigned to the inspection plan.

Note

You cannot define dependent characteristic specifications for master inspection characteristics referenced in inspection plans or for inspection characteristics in reference operation sets.

Example

In inspection plan "Pipes", there is a measurement inspection operation with several inspection characteristics. One of these characteristics, "diameter", has several dependent characteristic specifications, depending on the type of pipe.

Material	Target Value	Lower Specification Limit	Upper Specification Limit
Pipe 1	4.5	4.0	5.0
Pipe 2	7.5	7.0	8.0
Pipe 3	8.2	7.0	9.4
Pipe 4	5.0	4.0	6.0

When you inspect pipes, the system checks whether dependent characteristic specifications exist in the inspection plan for pipes. If this is the case, the system then uses these dependent characteristic specifications in the inspection. If there are no dependent characteristic specifications in the inspection plan, at the inspection the system uses the values defined for the inspection characteristic.

Prerequisites

One or more materials are assigned to the inspection plan. You can make an assignment at any stage during processing of an inspection plan.

Activities

On the inspection characteristic overview screen, you select the requested inspection characteristic or you enter in the context block the inspection characteristic, to which you want to assign dependent characteristic specifications.

You choose Task list ® Dependent characteristic specifications.

The overview of the dependent characteristic specifications appears.

You choose the tab page Dependent characteristic specs general and select the required combination of material, vendor and customer using the input help.
You choose the tab page Quantitative data and enter the dependent characteristic specifications (for example, specification limits and target values) for quantitative inspection characteristics.

Note

If you define dependent characteristic specifications for a quantitative characteristic, you can use a tolerance key.

You choose the tab page Catalogs and enter the dependent characteristic specifications (for example, selected sets, defect code in case of rejection).
To delete existing dependent characteristic specifications, mark the required assignment and choose Delete.
