Building a FMEA from FRACAS Incidents
You can use the Build FMEA from FRACAS Wizard to create a component FMEA from FRACAS incidents when both the FMEA and FRACAS modules are in use. If only one of these modules is in use, the Build FMEA from FRACAS command is unavailable. The purpose of this wizard is to create FMEA mode records from FRACAS incident records. For more information, see FMEA Mode Record Creation from FRACAS Incident Records.

The pages in this wizard use singular names for referenced tables. If custom table names are specified, text and option labels use the custom names rather than the default names. For more information, see Specifying Table Settings.

1. Ensure that both the FMEA and FRACAS modules are in use.
2. Select the FMEA Table to make it active.
3. Select > . The Build FMEA from FRACAS Wizard starts and displays the Target File page.
4. Select the appropriate option, referring to the following table for
option descriptions.

Create a new FMEA in this System File
|
When selected (default), the new FMEA is built in the open System file.
|
|
Create a new FMEA in an Assembly Library
|
When selected, the new FMEA is built in the specified Assembly Library file. To specify the Assembly Library file, the field below this option is made available. When you click its browse button, a selection window opens. To create a FMEA in an existing file, you click the file. To create a FMEA in a new file, you click < Create new file >, which is immediately replaced by < Type new file name here and press Enter >. You then click this command, enter a name for the new file, and click the green checkmark. To change your selection, you click the browse button again and, when the window opens, select the file. If you select < No selection >, any file information is discarded and the < Select file... > label is shown in the field to indicate that no file is selected.

5. After selecting the desired option, click Next.
◦ When a component FMEA exists for the selected system tree configuration, a window opens, indicating that a FMEA cannot be built because no configurations are available. Clicking OK closes this window.
◦ When multiple configurations exists, the Configuration Selection page appears. Go to step 6. Otherwise, the Filter/Select Records page appears. Go to step 7.
6. If the Configuration Selection page appears, select the configuration. The default is the active configuration in the Configurations table.
The configurations that you can select depend on whether you are creating the FMEA in the System file or an Assembly Library file. For a System file, only configurations that are not already associated with a component FMEA are available. For an Assembly Library file, all configurations are available.
◦ To select the active configuration, click Next.
◦ To select a different configuration, click the drop-down control. A window opens, listing the configurations from which you can select. Clicking a configuration selects it on the Configuration Selection page. Click Next.
The Filter/Select Records page appears. On this page, you can choose any filter for the FRACAS Incidents table to select the incidents that you want to use in creating the FMEA. You can also choose to limit the incidents selected to only those associated with a particular assembly or part in the System Tree items table.
7. Select a filter and/or use Filter by System Tree item options to indicate which incidents to use to build the new FMEA.
◦ When - - No Filter - - is selected, no filter is applied. If a filter is applied, you can change the selection or remove it by selecting - - No Filter - -.
◦ If you select the Filter by System Tree item checkbox, a field becomes available for choosing the specific system tree item. Clicking its drop-down control opens a selection window. Clicking an item selects it in the field on the Filter/Select Records page.
Only incidents meeting the specified filter criteria are used to build the new FMEA.
8. When finished, click Next. The Common Field page appears. This page lets you choose a field in the System Tree Items table to use to group the same assemblies and parts together. The default choice is Part Number. During the FMEA build process, any FRACAS incident under a system tree item creates FMEA records under all system tree items with the same part number. To consider each system tree item, you select *No Common Field.
9. Select the field to use for grouping the same assemblies and parts; then, click Next. The FMEA Field Mapping page appears so that you can indicate how to copy data from FRACAS Incidents fields into FMEA Worksheet fields.
On this page, the first column lists available fields in the FMEA Worksheet table. Special FMEA fields such as source and identifier fields are not shown.
When you click in the second column, a drop-down list shows fields in the FRACAS Incidents table. Only fields that are the same type as the field selected in the first column are shown. For example, the drop-down list for Item Failure Rate shows only numeric fields.
10. To map FMEA Worksheet fields to FRACAS Incidents fields, do the following:
a. In the first column, select Failure Mode and map it to the FRACAS Incidents field that contains the failure mode data for the FMEA. You must provide a mapping for this field.
If the automatic roll up of effects is turned on, when you map Local Effect to a FRACAS Incidents field, the text copied into the FMEA is inserted as the failure mode for the next higher item in the FMEA Tree table.
b. When finished mapping fields, click Next. The Wizard Complete page appears.
11. Click Finish to build the FMEA. Any new list choices are automatically added to lists.
A window opens while the data is copied to the newly created component FMEA. To stop this process, you would click Stop.
Once the data is copied, a window opens, indicating that the FMEA has been built successfully.
12. Click OK to close the window.
If you created this new FMEA in the System file, when you select it in the FMEA Table, the FRACAS incident data used to create it is visible in the FMEA Worksheet fields. If you created this new FMEA in an Assembly Library file, the target file opens, the system tree items for the selected configuration are copied, and then FMEA records are inserted in this file. If the creation fails, a window opens, asking whether you want to delete the partially created FMEA. Deleting it also deletes the new system tree items copied into this Assembly Library file.
