Creating and Updating BOMs: 5-5
Example
The project was called STRANGELOVE. Its PCB assembly part number was
115769-A, belonging to class code 920. All of the other parts, as shown in the
following table, reported to this part. Notice that most of them were from
documentation-only classes (sub, mec, sch, and mod).
Nested or Indented BOMs
Consider the serial number (S/N) PROM kit listed in Table 5-2. As a 119 class
code or materials group component, it reports to a 920-level PCB. A part number,
115779-A, was taken out for this kit.
When a software engineer developed the device file for this PROM, the software
was assigned a part number. The raw device (the PROM itself—a 120-level part)
and its specification each have a part number. These three components (file,
PROM, and spec) are combined into a BOM using a mechanical include file. This
BOM is a 119-level part that reports to part 115769-A.
Note:
You could use
mechbom
to create the 119-level BOM for the S/N PROM kit, or you could
call an EDA analyst to generate one for you.
When you request that this 119-level BOM be uploaded to SAP, you will specify
that its parent is the 920-level BOM, part number 115769-A. Thus 115779-A
becomes a BOM, nested or indented within the PCB assembly to which it
reports—BOM 115769-A.
