Parts List

After you have created the ECO and defined the routing instruction, you must define the change and identify the affected items. For all engineering change types except swap parent, you must enter information about the change for other items on the ECO Related Items List form.

You can use the UDC Next Revision Levels (30/NR) to automatically update revision levels based on the sequence that you define. Revision levels usually require an ECO and are for permanent, long-term changes. Revision levels include changes to form, fit, or function; and should match on a bill of material and routing instruction for the item. However, ECO does not update the Routing Revision Level. You can track changes in a bill of material with revision levels. Use the Item Revision Level field in the Enter/Change Bill program (P3002) to display a revision history of the bill. These revision levels are user-defined and for reference only.

The values that you enter in the Chg Type (Change Type) and P/C Rel (Parent/Component Relationship) fields on the ECO Parts List Entry form define the changes and determine how the Engineering Change Population program updates the bill of material for the item.

You can use values in the Chg Type and P/C Rel fields:

Field	Values
Chg Type	N: Add a new part. C: Change an existing part. S: Swap an old part with new part. R: Remove an existing part.
P/C Rel	P: Parent item. C: Component item.

Field

Values

Chg Type

N: Add a new part.

C: Change an existing part.

S: Swap an old part with new part.

R: Remove an existing part.

P/C Rel

P: Parent item.

C: Component item.

The Chg Type and P/C Rel fields allow eight possible combinations. These combinations are:

On the ECO Parts List Entry form:

Change	Change Type	P/C Rel	Information that You Enter	Revision Level
Add a new bill	N	P	Parent item for the new bill.	New parent revision.
Change a bill	C	P	Current parent item.	Current parent revision.
Swap a parent item	S	P	Swap to parent item. Swap from parent information.	Swap to parent revision. Swap from parent revision.
Remove a bill	R	P	Current parent information.	Current revision.
Add a new component	N	C	New component.	New component revision.
Change a component	C	C	The component to change.	New revision of component.
Swap a component	S	C	Swap to component. Swap from component.	Revision of swap to component. Revision of swap from component.
Remove a component	R	C	The component to remove.	Revision of component to remove.

On the ECO Related Items form:

Change	Change Type	P/C Rel	Information that You Enter	Revision Level
Add a new bill	N	P	Components for the new parent.	Revision level of added components.
Change a bill	C	P	Updated parent information.	New revision.
Swap a parent item	S	P	Not allowed.	Not allowed.
Remove a bill	R	P	Not allowed.	Not allowed.
