Sample plan frequency

You can use the Sample Plan Frequency module to create, maintain, and remove sample plan frequency definitions.

When you open the Sample Plan Frequency module, a list of existing sample plan frequencies is shown.

A sample plan frequency is the given interval for collecting samples for measuring quality. A sample plan frequency can be associated with multiple sample plans and a sample plan can have multiple sample plan frequencies.

Sample plan frequencies are defined based on the following:

• Calendar or clock time

• Time pattern within current shift

• Production unit count

• Occurrence of specific events (job start or end, lot number change for the main item being produced)

There can be multiple sample plan frequencies at any given time.

By default, the Sample Plan Frequency module is in the Quality Management group in the Navigation Bar. For more information on groups and modules, see Groups and modules.

You can modify an existing sample plan frequency, except under the following conditions:

• You cannot modify the type of a sample plan frequency if it is linked to a sample plan.

• You cannot modify the Data Change event type of a sample plan frequency if it is linked to a sample plan.

You can delete an existing sample plan frequency from the MES database if it is not linked to any sample plan. For more information on deleting, see Delete an object.

Note: An error message appears if the sample plan frequency cannot be saved. Modify the sample plan frequency, as needed, to correct the error and save to clear the error.
