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 Note

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

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

In the inspection characteristic overview, you mark the required inspection characteristic.
To process dependent characteristic specifications, in the line of the table for the required inspection characteristic, choose Create dependent characteristic specs or Change dependent characteristic specs.

The overview of the dependent characteristic specifications appears.

To enter new dependent characteristic specifications,

Choose Insert assignment
In the list of material-task list assignments that is displayed, mark the required combination of material, vendor and customer and choose Choose.

To enter data for the dependent characteristic specifications, mark the required combination of material, vendor and customer.

Choose Quant.Data and enter specification limits and target values.

Note Note

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

Choose Catalogs and enter code groups or selected sets.
