Overview

SAP Job Scheduling Service is a runtime-agnostic platform service for defining and managing one-time and recurring jobs or Cloud Foundry tasks on SAP BTP. It operates across multiple hyperscalers (AWS, Azure, GCP) without requiring application modifications.

When to Use This Skill

Use this skill when:

• Setting up Job Scheduling Service on Cloud Foundry or Kyma runtime
• Creating and managing jobs via REST API or dashboard

Core Concepts

Job

A collection of schedules with an action endpoint. Jobs invoke a configured URL at specified times synchronously (short operations) or asynchronously (long processes).

Schedule

A one-time or recurring entity within a job. Supports multiple formats (cron, date/time, human-readable) and has three lifecycle states: SCHEDULED → RUNNING → COMPLETED.

Action Endpoint

An HTTP/REST endpoint exposed by your application that the service invokes when schedules trigger. Must be OAuth 2.0 protected in production.

Cloud Foundry Task

An app or script that runs independently in its own container. Always executes asynchronously with configurable memory allocation.

Best Practices

Scheduling Optimization

Avoid Peak Times:

• ❌ 0th or 30th second of any minute
• ❌ 0th, 30th, or multiples of 5 minutes
• ❌ Top of each hour
• ❌ Midnight UTC (busiest time)

Use Irregular Times:

• ✅ 01:12:17 instead of 01:00:00
• ✅ 01:38:37 instead of 01:30:00

Asynchronous Jobs

1. Return 202 Accepted immediately - Don't block the request
2. Store request headers - x-sap-job-id, x-sap-job-schedule-id, x-sap-job-run-id, x-sap-scheduler-host
3. Update run log on completion - Single API call with final status
4. Handle timeouts - Default 30 min, configurable up to 7 days

One-Time Schedules

• Use only for testing/validation
• Auto-deactivate after execution
• Use "time": "now" for immediate execution

Authentication Quick Start

Standard Plan (OAuth 2.0)

# Get access token
curl -X POST "<uaa_url>/oauth/token" \
  -H "Authorization: Basic $(echo -n '<clientid>:<clientsecret>' | base64)" \
  -d "grant_type=client_credentials"

# Use token in API calls
curl -X GET "[https://jobscheduler-rest.<landscape>/scheduler/jobs"](https://jobscheduler-rest.<landscape>/scheduler/jobs") \
  -H "Authorization: Bearer <access_token>" \
  -H "Content-Type: application/json"

xs-security.json Configuration

{
  "xsappname": "<app-name>",
  "scopes": [{
    "name": "$XSAPPNAME.JOBSCHEDULER",
    "description": "Job Scheduler Scope",
    "grant-as-authority-to-apps": ["$XSSERVICENAME(<jobscheduler-instance>)"]
  }]
}

Create Job Example

POST /scheduler/jobs
{
  "name": "myJob",
  "description": "Process daily reports",
  "action": "[https://myapp.cfapps.eu10.hana.ondemand.com/api/process",](https://myapp.cfapps.eu10.hana.ondemand.com/api/process",)
  "active": true,
  "httpMethod": "POST",
  "schedules": [{
    "active": true,
    "description": "Daily at 6 AM",
    "repeatAt": "6.00am",
    "startTime": {"date": "2025-01-01", "format": "YYYY-MM-DD"}
  }]
}

Node.js Client Library

Requirements: Node.js 14.x or later

npm install @sap/jobs-client@1.8.6

const JobSchedulerClient = require('@sap/jobs-client');
const scheduler = new JobSchedulerClient.Scheduler();

// Create job
scheduler.createJob({ url: vcapServices.jobscheduler[0].credentials.url }, {
  name: 'myJob',
  action: '[https://myapp.../process',](https://myapp.../process',)
  active: true,
  httpMethod: 'GET',
  schedules: [{ cron: '* * * * 0 0 0', active: true }]
}, (err, result) => { /* handle */ });

Rate Limits

Limits stack - both can apply simultaneously.

Service Behavior

Outage Recovery

Auto-Deactivation Triggers

• One-time schedule executed
• No valid future dates exist
• Job/schedule endTime reached
• Action endpoint unreachable for 10+ days

Common Pitfalls

Setup:

• ❌ Missing XSUAA binding before Job Scheduling binding
• ❌ Not granting scopes via grant-as-authority-to-apps
• ❌ Using HTTP instead of HTTPS for action endpoints

Scheduling:

• ❌ Using Linux cron format (service uses SAP cron)
• ❌ Scheduling at peak times (00:00, 00:30, etc.)
• ❌ Forgetting UTC timezone (only supported timezone)

Async Jobs:

• ❌ Not returning 202 Accepted immediately
• ❌ Forgetting to call Update Run Log API
• ❌ Multiple status updates instead of single final update

Multitenancy:

• ❌ Using tenantId filter with SaaS tenant tokens (returns 400)
• ❌ Missing Job Scheduling as application dependency
