Building a FMEA Fault Equivalence File from a FMEA

Windchill Risk and Reliability Desktop Help > Windchill FMEA > FMEA Interface > FMEA How-Tos > Building a FMEA Fault Equivalence File from a FMEA

You can build a new FMEA Fault Equivalence file for the Project from a FMEA in a System file. Because both the Project’s FMEA Design file and Fault Equivalence files are modified as a result of this process, they are automatically backed up before the new FMEA Fault Equivalence file is built. For more information about these files, see FMEA Support Files.

1. In the FMEA Table, select the FMEA.

2. Select FMEA > Build Fault Equivalence File. The FMEA Fault Equivalence Wizard starts. The page that appears depends on whether the Project’s FMEA Design file has key and fault equivalence data fields defined. If these fields are not defined, the Select Key Fields page appears. Go to step 4. Otherwise, the Update Existing File or Create New File page appears.

3. On the Update Existing File page or Create New File page, indicate whether you want to update the existing file or create a new one. The option for updating the existing file is the default.

If you accept this default and click Next, the Wizard Complete page appears. Go to step 8.

If you select the option for creating a new file and click Next, the Select Key Fields page appears.

4. Complete the Select Key Fields page, referring to the following table for

option descriptions

. If you selected the option for creating a new FMEA Fault Equivalence file in step 3, the key fields selected in the existing file are shown in the Key fields selected list.

Option	Description
Key fields available	Lists all of the FMEA data fields that can be selected as key fields for the FMEA Fault Equivalence file.
Key fields selected	Lists the FMEA data fields that have been selected as the key fields for the FMEA Fault Equivalence file. The first field in this list is the first key field, the second field in this list is the second key field, and so on. As many as five key fields can be selected. If you select more than five key fields, when you click Next, a window opens, indicating that the maximum number of key fields is five. Once you click OK to close this window, you can remove fields until five or fewer are selected.
	When clicked, the field selected in the Key fields available list is moved to the Key fields selected list. You can also double-click a field in the Key fields available list to move it to the Key fields selected list.
	When clicked, the field selected in the Key fields selected list is moved to the Key fields available list. You can also double-click a field in the Key fields selected list to move it to the Key fields available list.

5. Once five or fewer key fields are selected, click Next. The Select Data Fields page appears. If you selected the option for creating a new Fault Equivalence file on the Update Existing File or Create New File page, the fault equivalence data fields selected in the existing file are shown in the Data fields selected list by default.

6. Complete the Select Data Fields page, referring to the following table for

option descriptions

Option	Description
Data fields available	Lists all of the FMEA data fields that can be included in the FMEA Fault Equivalence file.
Data fields selected	Lists the FMEA data fields that have been selected for inclusion in the FMEA Fault Equivalence file. The first field in this list is the first field, the second field in this list is the second field, and so on. You can select any number of fields.
	When clicked, the field selected in the Data fields available list is moved to the Data fields selected list. You can also double-click a field in the Data fields available list to move it to the Data fields selected list.
	When clicked, the field selected in the Data fields selected list is moved to the Data fields available list. You can also double-click a field in the Data fields selected list to move it to the Data fields available list.

7. When finished, click Next. The Wizard Complete page appears.

8. Click Finish to update or create the FMEA Fault Equivalence file, depending on the selections you have made.

First, the Project’s existing FMEA Fault Design and Fault Equivalence files are backed up in case the previously existing versions must be restored. Then, the data in the active FMEA in the System file is used to either update the existing FMEA Fault Equivalence file or create a new one. You can open the current FMEA Fault Equivalence file to view or enter additional FMEA data.
