Procedure documentationCopying Characteristics

 

When you copy critical characteristics from a Failure Mode and Effects Analysis (FMEA) to the control plan (CP), you can link the FMEA characteristics to the inspection characteristics that belong to the corresponding inspection plans and task lists.

Prerequisites

  • You have assigned a task list and an inspection plan to a control plan item for the prototype phase.

    From the control plan, you can also create a new task list or inspection plan for a control plan item.

  • You have specified all of the objects (such as material, plant, key date, inspection plan or task list) that are relevant for the control plan in the prelauch and production phases.

    From the control plan, you can also create a new task list or inspection plan for a process.

  • In the task list or inspection plan, you have specified operations for which the characteristic is planned.

Note Note

If there are not yet any operations specified in the task list or inspection plan, you can branch from the CP structure view to a task list or inspection plan. Here you can specify operations in edit mode:

  1. Choose Show Plan Header in the context menu of the task list or inspection plan. The plan header is displayed in the Engineering Workbench (EWB).

  2. Switch to change mode and choose    Plans  Operations   in the operations overview.

  3. Create the required operations.

    For more information, see Processing Inspection Operations.

  4. Finally, choose Back (Back) to return to the CP structure display.

  5. Choose Refresh (Refresh) to update the structure display.

End of the note.

Procedure

  1. Choose the Structure tab page in the edit screen for the control plan.

    The tree structure shows an overview of all of the inspection plans that belong to the control plan.

  2. Choose an inspection plan or task list by placing your cursor on the relevant symbol.

  3. Choose Copy Characteristic in the context menu of the task list or inspection plan. The system displays the screen for copying characteristics to the control plan.

    You see an overview of the plan structure for the task list or inspection plan. You also see a table containing FMEA characteristics and a table containing inspection characteristics.

  4. Select an FMEA in the Characteristic Origin input field.

    Note Note

    If you want to use other characteristic origin, apart from the FMEA, you must first specify these in Customizing using the BAdI Define Characteristic Origin. You will then be able to use additional characteristic origins, which will appear in a dropdown list in the Characteristic Origin input field.

    End of the note.

    Select an FMEA in the FMEA input field.

  5. Choose Load Characteristics.

    The FMEA characteristics are listed in the FMEA Characteristics table.

  6. Choose the characteristic that you want to use from the list. In the plan structure for the operations, select the operation that you want to assign the characteristic to.

  7. Choose Add Characteristic to Plan (Add Characteristic to Plan).

    Alternatively, you can use drag and drop to assign the characteristic to the desired operation in the plan structure.

    A characteristic can be used multiple times for different operations.

    The new characteristic to be copied is displayed in the Inspection Characteristic table.

    Note Note

    You can only specify new characteristics in a task list or inspection plan. You cannot process characteristics that are already in a task list or inspection plan.

    End of the note.
  8. In the Inspection Characteristics table, enter an inspection characteristic number in the Inspection Characteristic column. This allows you to identify the inspection characteristic in the operation. It also, for example, allows you to determine the order used for the display of the characteristics in the control plan.

    You can also enter additional data, such as Unit of Measure, Lower Limit Value or Upper Limit Value.

  9. Check all of the copied characteristics. To do this, choose Check Copied Characteristics (Check Copied Characteristics). The system displays a log. This shows whether the characteristics can be copied.

  10. Choose Save Transferred Charact. and Close (Save Transferred Charact. and Close). The system displays a log. This shows whether the system copied and saved characteristics successfully.

  11. Finally, choose Back (Back) to return to the CP structure display.

    Caution Caution

    The characteristics are valid from the moment that they are copied. If the characteristics are not displayed on the Structure tab page in the CP structure view, check the Selection Date on the Basic Data tab page, under Structure Specifications.

    If the selection date is after the date on which the characteristic was copied, the characteristic is displayed in the control plan structure.

    End of the caution.

Result

You have copied one or more characteristics from an FMEA to the control plan. You have also assigned these characteristics to an operation in the corresponding task list or inspection plan.

You can also perform a consistency check, to check whether the FMEA characteristics were considered in the corresponding inspection plans or task lists.
