SAP CPI Trouble shoot

One thing I stopped doing in CPI projects:

Looking at the error first.

Most of the time the error is just a symptom.

The first thing I check now is what changed in the last few days. New deployment, mapping update, value mapping change, certificate renewal, endpoint update... that's usually where the answer is hiding.

Saved me more hours than any monitoring tool.

What's the first thing you check when a flow suddenly starts failing?

If you're stuck on a weird CPI issue right now, send me the scenario. I enjoy troubleshooting these.
