Hi Everyone,

We were inspecting our package of CDTs to deploy to our QA environment and for one of the CDTs we received the following error message.

which already exists with a different structure. The requested type will not be created and the existing type will not be altered. You must first delete the existing type if you intend to redefine it with a different structure. (APNX-2-4045-001)

When we looked into the Data Management section, we are unable to see this CDT so we are currently unable to delete it.

Has anyone experienced this before? Our user type is system administrator so I assumed we should be able to see all CDTs installed in the system.

We are currently using Appian 7.6 Hotfix A.

Thanks,
Felix...

The only time I have every received this error was when the CDT existed. Are you sure the CDT does not exist? Did you see if you have multiple tabs? Another thing you might try is to open an existing process model and try to create a new variable of the CDT type to see if it shows as a selection.

Thanks for the reply Helmuta.

We have checked the multiple pages of CDT listing but haven't found this one listed. We did the test to try an select this CDT as a process variable data type in a process model. The auto complete selection wasn't able to find it. Also tred browsing the list of data types unfortunately wasn't able to find it this method either.

Try opening a process model that uses that CDT and create the documentation and see if the CDT shows up in the documentation. It is located under the Tools tab in the process modeler.

If you are not seeing it under Data Management and this CDT comes from a web service is because somebody created a process model that points to the web service that creates that CDT but didn't publish the model, this craetes the CDT but doesn't expose it.

You need publish that model to expose it and be able to delete it; if you cannot find the model you can try creating a new one in that environment, make it point to the web service so it creates the CDTs and publish it; this way they will become visible.

Awesome, thanks Eduardo. I couldn't find the original process model that may have created the web service cdts. I made a new process model with a call web service node that points to the same web service. After I published this model I checked in Data Management and the old cdts were now visible and I was then able to delete them.
