Hello together
I am working on a workflow that should have the following function. My workflow should check if an ID already exists as a sharepoint entry. If it exists, then it should overwrite it please. If not it should create a new one.
However, I have the problem that it checks every entry and then simply creates all entries twice. Attached are the images (with german headline)

In my test I wanted to check if the ID 15.11.2030 already exists and if so overwrite it but it created a new entry and duplicated the other entries too
For my power app, here's how I thought about it:

I wanted to address the ID field directly. Then I wanted to create a variable with the value of the ID field

Then I call my elements off I would not know now what I could write here still purely.
There is also the selection retrieve element but here I would need an ID and this I would have to write with a f(x) there I would not know what must purely there, therefore I have not used it.

After the Get Items command I check if my PowerApp ID is the same as an ID in my sharepoint if so it should take the left path and update it. If no create a new entry.
But it only creates new items and I would need help here very urgently.
