Creating and Updating BOMs
A
BOM
(Bill of Materials) is essentially a list of parts, some of which may be
BOMs themselves.
• The BOM that contains parts is their
parent
. They are said to
report
to that
BOM.
• A BOM contained as a part number within another BOM is called a
nested
, or
indented
BOM.
The BOM process’s main purposes are to:
• Generate a BOM (and associated files)
• Compare a BOM with a previous one
When you create a BOM, you create data files that are required to create a PCN.
One,
project
.sap
, contains information that EDA personnel will upload to SAP;
some are for engineering use; and some are for input to the PCN, which produces
a report so that other people on your project are notified of the changes.
This chapter explains how to create a BOM. The following chapter explains how
the BOM and related files are uploaded to SAP and used to generate a PCN.
