03Which decisions can change the result?
Review capture the exact identity, normalize the bom, check generation, check completeness. The complete project and article-number context determines the final answer.
Procurement guide framework
Six checks for this decision
Apply these checks to siemens article-number and bom verification workflow so assumptions are visible before the BOM, drawing, procurement release or shutdown plan is approved.
Capture the exact identity
Record every character and suffix from the label, plus firmware or hardware version, quantity and destination where relevant.
Normalize the BOM
Separate part number, description, quantity and tag; flag incomplete, duplicated or ambiguous lines without silently guessing.
Check generation
Compare CPUs, modules, HMI, drives and accessories within the same system generation and engineering environment.
Check completeness
Review base units, connectors, memory, operator panels, communication modules, filters, reactors and mounting accessories.
Control substitutions
Show original and proposed article numbers, technical differences, software or wiring impact and approval status.
Release the quotation basis
Tie price, lead time, documents and warranty to the approved revision and list unresolved technical assumptions.
