Creating and Updating BOMs: 5-17
Specifying Configuration File Parameters
The config file can be confusing, as it contains combinations of supported,
unsupported, and obsolete options. In general, keep in mind that the main point is
either to:
• Create a BOM using include files managed by a mechanical engineer and kept
in subdirectories under
/bay
dir
/dra/2brel/mech
,
/bay
dir
/dra/2brel/
programs
, and
/bay
dir
/dra/2brel/docs
.
• Create a BOM using parts extracted from a schematic, with or without
combinations of mechanical, device, and documentation files as above, one or
more parts of which can be placed in other directories.
The order of the config file’s parameters does not matter. You may organize them
however you wish. However, the order of execution of include, change, and depop
files is as follows:
1.
Include files (in order if multiples) and parts lists generated from schematics.
2.
Depop files, in order if there are multiples.
3.
Change files are applied, in order if there are multiples.
The generated config files should need relatively minor tweaking. If you’re a
design engineer, you will want to check (and edit, if needed) at least the following
settings:
NEW_BOM_TYPE VL_SCHEM_EXTRACT
OLD_BOM <your-920-level part number>.saplis
OLD_BOM_TYPE SAP_REPORT
BUILD_NEW_PARTSLIST YES
EXTRACT_FROM_SCHEMATIC YES
BUILD_NEW_PROTO_DIFF YES
Note:
If you’re a mechanical engineer,
you probably won’t use the config file at all
, but if you do,
you may want to change two of the above statements as follows:
EXTRACT_FROM_SCHEMATIC NO
and
INCLUDE <your mechanical parts files>.
See
bn_bomprocess Messages
on page D-2 for help with some of the error
messages that you may see with inconsistent configuration parameters.
Caution:
The
bn_bomprocess
checks for quantity/refdes mismatches and will fail if the number
of reference designators does not match the process’s count of items. To prevent this, use the
config file statement
ADD_REFERENCE_INFO_FOR_DOWNLOADS NO
.
