IDocs are not the problem
IDocs are reliable, transactional and well understood. The problem is usually everything around them: undocumented partner profiles, silent error queues, custom monitoring that only one person understands, and no consistent retry policy.
Step 1: make the current state visible
- Inventory active message types, partners and volumes
- Measure error rates per message type over a full month
- Identify who currently notices a stuck queue, and how long that takes
Step 2: fix operations before architecture
Automated monitoring and clear error ownership usually removes more pain than any replatforming. Many teams discover their integration is fine and only their alerting was missing.
Step 3: replace selectively
- New external partners and cloud services: build on APIs and SAP Integration Suite
- Stable high-volume internal flows: leave on IDoc until there is a business reason to move
- Batch file interfaces: usually the best first migration candidate
Step 4: run both worlds deliberately
Hybrid is a valid target state, not a failure. Define one place where every interface is documented, one alerting channel, and one on-call responsibility, regardless of technology.
What good looks like after twelve months
Error rates are known and trending down, every interface has an owner, and adding a new partner is a routine task rather than a project.
Frequently asked questions
- Should we replace all IDocs?
- No. Stable high-volume internal flows rarely justify migration. Prioritise new partners, cloud services and fragile file interfaces.
- What delivers value fastest?
- Monitoring and clear error ownership. Most integration pain comes from unnoticed failures, not from the transport technology.
