The selected component is not supported. The input port has duplicate context elements.

I'm trying to create a process using SAP Business Process Management.

I've created a screen flow using visual composer, the flow uses a web service to create a purchase request.

When i try to assign my model to my step in Netweaver Developer Studio, i get the error:  The selected component is not supported. The input port has duplicate context elements.

I can figure out how to resolve this error.

Jakob,

I just ran across this same issue today.  The Process Composer is expecting the data on the START point in your VC model to have all unique names.  For example, I don't believe you can have 2 elements under different nodes with the name InternalID. 

To fix this issue you should do the following...

1) Open your VC model

2) Right click on the START point and click DEFINE DATA

3) Open all of the nodes on the left hand side

4) Rename any nodes on the left hand side that are duplicated

5) Rename any field names on the right hand side that may be duplicated

6) Close, Save, Deploy...

Now you should be able to choose this VC component from BPM.
