FMEA Tree Items Table

Windchill Risk and Reliability Desktop Help > Windchill FMEA > FMEA Interface > FMEA Panes > FMEA Tree Items Table

The FMEA Tree Items table defines the hierarchical structure for the FMEA selected in the FMEA Table. For a process or functional FMEA, process stages or functions are inserted in the same way as you insert assemblies and parts in the System Tree Items table. For more information, see System Tree Items Table.

A suffix is added to the name of the FMEA Tree Items table to indicate the type of FMEA selected in the FMEA Table:

• When a component FMEA is selected, the default name is FMEA Tree Items - System.

• When a process FMEA is selected, the default name is FMEA Tree Items - Process.

• When a functional FMEA is selected, the default name is FMEA Tree Items - Functional.

The Table Format file for the FMEA Tree Items table determines the data fields that appear. The following table describes the fields that are shown by default. For more information, see Table Format Files.

Field	Description
Name	The name of the item.
Part Number	The part number assigned to the item.
System Tree Identifier	The unique identifier assigned to the item in the FMEA Tree Items table. While an identifier is assigned to the item when it is inserted, you can change it to any unique value. The format for the assigned identifier is specified by FMEA Tree Item Identifier, which appears under Identifiers in the System file properties. For more information, see Identifiers System File Properties.
Reference Designator	The reference designator for the item. For example, the reference designator might be U1, R22, or C15.
Description	A description of the item.
Manufacturer	The manufacturer of the item.

Guidelines

Guidelines follow for the three different types of FMEAs.

• When you insert a process FMEA, the FMEA Tree Items table contains only the top-level item. To construct the system definition for the process FMEA, you name this top-level item, which represents the entire process, and then insert assemblies and parts to represent the various stages and substages to analyze.

• When you insert a functional FMEA, the FMEA Tree Items table contains either a top-level item or a copy of a System Tree Items table, depending on the selection you made on the Select FMEA Basis page in the New FMEA Wizard.

◦ If the table contains only a top-level item, you name this top-level item, which represents the function, and then insert assemblies and parts to represent the various components and/or interfaces to analyze.

◦ If the table contains a copy of a System Tree Items table, you make any necessary changes to the assemblies and parts to represent the various components and/or interfaces to analyze. For a functional FMEA, the FMEA Tree Items table and the System Tree Items table are not tied together in any way. Consequently, changes to assemblies and parts in one of these tables are not made in the other table. Copying a selected System Tree Items table is merely a starting point for the system definition.

• When you insert a component FMEA, the FMEA Tree Items table contains a copy of a selected System Tree Items table. For a component FMEA, this two tables are tied together. Consequently, changes to assemblies and parts in one of these tables are made in the other table.

The item selected in the FMEA Tree Items table determines the data to show in the FMEA Worksheet table. Because you can expand or collapse branches in the FMEA Tree Items table, you can quickly select any item to view the data captured for it in the FMEA Worksheet table. For more information, see Expanding and Collapsing Branches.

In the Enterprise Edition only, the FMEA Tree Items table supports 15 subtables.

You can create and apply filters to limit the data shown in the FMEA Tree Items table. When a filter is applied to this table, you cannot delete records from it. For more information, see Filters.

You can import data into or export it from the FMEA Tree Items table. Prior to starting an import or export, you must select the appropriate FMEA in the FMEA Table. Data can be imported into or exported from all three FMEA types. Importing data into the FMEA Tree Items table is similar to importing it into the System Tree Items table. For more information, see Importing and Exporting and Importing System Tree Items.

For a component FMEA, you can create and use Assembly Library files to enhance, simplify, or further refine the entry of assembly data in the FMEA Tree Items table. For more information, see Assembly Library Files.
