Source-to-Pay Suite — Purchase requisitions
Privacy approval carries a condition: the requester name must be pseudonymized before it reaches the spine, which the staging boundary now enforces.

Cardinality
One requisition to many lines. One line to at most one purchase order line. A requisition line with two purchase order lines is a source defect and quarantines.
Write-back rule
Requisition creation and requisition cancellation are in scope. Award and contract signature are not, and the contract forbids them explicitly.
Review state
Neither review is performed by the team that wrote the contract.

Validation and drift
Drift is only detectable on a contract that has been read against a sample.
Last validatedAug 12, 2026 · 6 d ago
8,000 records read in the sample.
The last sample found the supplier tax identifier arriving as a free-text string where the contract declares a structured type, and a new approval-delegate field present in the payload that the contract does not name. more
The field list
6 fields · 2 key · 2 personal. The validation rule on each row is what admits or rejects a record at the staging boundary.
| Field | Source | Target | Type | Flags | Drift | Validation |
|---|---|---|---|---|---|---|
| Requisition id | BANFN | requisition.ref | string(10) | keyinternal | In contract | Unique. Reused numbers across company codes are a known source behavior and are namespaced on entry. |
| Line number | BNFPO | requisition.line | integer | keyinternal | In contract | Positive. Gaps are permitted; duplicates are not. |
| Supplier tax identifier | STCEG | requisition.supplierTaxId | string(20) | nullableinternal | Type changed Arriving as unvalidated free text in the last sample. more | Structured by jurisdiction. Validated against the country format table before admission. |
| Requested by | AFNAM | requisition.requesterHash | string(64) | personalconfidential | In contract | Pseudonymized at the boundary. This is the condition attached to the privacy approval. |
| Net value | PREIS | requisition.netValue | decimal(15,2) | internal | In contract | Positive. Must carry a currency or the line is quarantined. |
| Approval delegate | ZZDELEG | (unmapped) | string(12) | nullablepersonalconfidential | New and unmapped Present in the source payload since a source release earlier this month. more | Not declared in this version of the contract. |

What this contract is, and what it is not
A contract, a validation rule, a freshness commitment and a replay path are real mechanisms and they are what this wave builds. more
The last validation read 8,000 records 6 days ago, which is 24% of a single day at the declared volume. A sample proves the shape of what it read and nothing beyond it.
