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.

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.

Service Constraints

Constraint	Value
Minimum schedule interval	5 minutes
Synchronous request timeout	15 seconds
Asynchronous timeout (default)	30 minutes (configurable up to 7 days)
POST request body limit	100 KB
Run log retention	15 days
Service SLA	~20 minutes from scheduled time

Quick Reference Tables

Schedule Formats

Format	Example	Use Case
Cron	* * * * 10:12 0,30 0	Every 30 min between 10:00-12:00
Date/Time	2025-10-20T04:30:00Z	ISO-8601 one-time execution
Human-readable	tomorrow at 4pm	Natural language scheduling
repeatInterval	2 hours, 5 minutes	Recurring at fixed intervals
repeatAt	4.40pm, 18:40	Daily at specific time

Cron Format (7 fields)

Year Month Day DayOfWeek Hour Minute Second
*    *     *   *         *    *      *

Field	Values	Special
Year	4-digit (2025)	* = any
Month	1-12	*/a = every a-th
Day	-31 to 31	negative = from end
DayOfWeek	mon, tue, wed...	a.y = a-th occurrence
Hour	0-23	a:b = range
Minute	0-59	a:b/c = step in range
Second	0-59	a,b,c = multiple values

Schedule Lifecycle States

Phase	States	Description
SCHEDULED	SCHEDULED	Queued for future run
RUNNING	TRIGGERED, ACK_RECVD, ACK_NOT_RECVD	Executing
COMPLETED	SUCCESS, ERROR, REQUEST_ERROR, UNKNOWN	Finished

HTTP Methods for Jobs

Method	Endpoint	Purpose
POST	/scheduler/jobs	Create job
GET	/scheduler/jobs	List all jobs
GET	/scheduler/jobs/{id}	Get job details
PUT	/scheduler/jobs/{id}	Update job
DELETE	/scheduler/jobs/{id}	Delete job

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

Limit Type	Response Code	Header
Client limit exceeded	429	retry-after (seconds)
Absolute limit exceeded	503	throttling (milliseconds)

Limits stack - both can apply simultaneously.

Service Behavior

Outage Recovery

Outage Duration	Behavior
< 20 minutes	All missed executions run immediately
>= 20 minutes	Only last missed execution runs

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
