Public sector use case · Microsoft Azure + SAP + ServiceNow
Cross-agency file intake and validation
Files exchanged between agencies are opened by hand, checked inconsistently and keyed into finance systems. Errors surface weeks later. Files from other agencies are validated before they touch finance records, and problems become tickets.
Systems involved
What each system contributes
45 actions
- Blob Storage10
Trigger source: Azure Blob Storage, Azure Event Hub, Azure Service Bus, Azure Active Directory

File parsing runs as Rules + Code. Any SAP operation outside pre-built actions uses SAP RFC in the same workflow.
Architecture
One governed run
How it starts: A new file in Azure Blob Storage starts the run through the Azure Blob Storage trigger source.
Variant: The same pattern works with AWS S3 as the storage trigger, or with Google Drive read on a schedule.
Step by step
How the process runs
- 01
File lands
A new file in Azure Blob Storage starts the run.
- 02
Validate
Rules + Code parses the file and checks structure and values.
- 03
Check SAP
Related SAP finance, procurement or invoice records are read.
- 04
Write or hold
Valid entries are written to SAP. Anything else waits.
- 05
Exceptions
Failures open a ServiceNow ticket with the file reference.
Control
Human decision and exception path
Human decision
Entries above a value threshold or failing validation wait for a finance owner.
Exception path
- Malformed files are quarantined and ticketed.
- SAP write failures are retried and surfaced.
- Duplicate files are detected before processing.
Evidence
What gets audited
- The file reference and checksum.
- Validation results.
- Approvals for held entries.
- SAP responses and ticket references.
Nexus runs on premises, in private or sovereign cloud, or air-gapped. Credentials stay in the vault, roles decide who can approve, and the execution record stays inside your deployment boundary.

FAQ
Questions about this use case
- Does Nexus replace any of these systems?
- No. Each system keeps its own records. Nexus runs the process between them and records each decision.
- How does the run start?
- A new file in Azure Blob Storage starts the run through the Azure Blob Storage trigger source.
- What if a step is not covered by a pre-built action?
- File parsing runs as Rules + Code. Any SAP operation outside pre-built actions uses SAP RFC in the same workflow.
