Who owns an SAP interface

I'm currently working on an SAP PI migration, and one of the issues is identifying the interface stakeholders. Some are quite easy because you need constant communication with them. It could be the banking interface or the order processing interface.

But others often become much more exotic.

You created an interface because someone wanted to integrate SAP ECC with some SaaS application. The interface was delivered successfully, and the business accepted it. All documentation was created about why and who owned the interface.

It runs successfully without incidents for a year. Then, the person who initially requested the interfaces leaves the company. Ideally, you should update the interface to a new owner, but it needs to be remembered that it even exists. And then, into the mix, comes a reorg to mix things up.

Then, the interfaces start to produce errors. Who do you contact for it?

1. Either the application changes its API or authentication
2. Subscription is cancel

You would start to see some errors in your integration platform, and then you need to figure out how to react to them. It can be quite a challenge to find information about the interface and the responsibility. After some time, you may just get information from some business team that the application is no longer working. Then you have a contact.

If you are embarking on a migration project to SAP Integration Suite, it does make sense to understand how owners and an administrator can sign off on changes. This will also resolve the question of whether it even matters now.

How do you do it

How do you link a technical interface with business stakeholders in your organization?

Are you allocating the cost to the business for operating and changing their interface?

Do they know what you are upto with your integrations?

And more importantly, how do you ensure it is always up to date?
