Document Comparison
Compare an older version (Document A) with the current one (Document B, the project document at the top unless you choose another file): every changed row, tab by tab, with exactly what changed.
Choose Document A (older) and Document B (newer) above, then press Compare.

Inventory file
Open the latest inventory (stock on hand) from the team drive, or upload one there. It's shown below, and checked against the build sheet.
Cables are matched by type, then by length: each run gets the shortest stock length that reaches it. Transceivers are matched by name.
