Source registers and master documents.

The authoritative source records for supplier, product, capability, qualification and commercial data — the immutable master, its populated working copy, and the associated master documents.

Access is controlled by the document owner. Each link below opens the record in Google Drive and honours the sharing permissions set on that file. Where access has not been granted, the source will present a Google sign-in or request-access screen. Do not edit the immutable master; changes belong in the populated working copy.

01 — Source registers

Master workbook

The immutable master is the source of record. The populated copy is the working version used for enrichment and validation. Supplier IDs and structure are preserved across both.

Immutable master

The unedited master record. Treated as read-only; imports and migrations preserve its supplier IDs, ranking, priority, platform classifications, product groups, product lines and commercial fields.

Populated master

The populated working version of the master — the enrichment layer where records are completed and prepared for import. Unverified technical fields must be marked Pending verification.

Supporting documents

Three master documents are held in the shared drive. Their titles are Pending verification — the link access is restricted, so the site labels them by sequence only and does not invent their contents.
