SP onprem Managed Metadata generated by the server can't be specified

Hello there !

Before throwing my computer through the window, I thought it would be wise to ask your knowledges :

I have a application created from blank, desktop-wide. I have made the wanted connections with all the needed SP On-prem lists.

I have set several screens. One of them is the Create/Edit Case one.

In this screen, I've inserted a Edit Form, with "Case_List" as data source.

In that Case_List, on SP, I have a clumn called SectionMachine_RI. It is a managed metadata column. It is not even a multi-valued column.


But the TermSet contains a reusable term.

This is the only particularity I can find.


Here are the problems I encountered :

  1. when adding an Edit Form to my screen, I add the Fields to this edit form. My Managed Metadata fields are only showing two layouts : View Lookup and View Selection. (see below). Normally, it should show Edit Lookup and Edit Selection !

    I had to unlock the datacards and modify the DisplayMode to Edit. It customed my datacard and i was no longer able to see the different layouts.managedmetadata_error00.PNG


  2. When I finally added the managed metadata column, I can see a dropdown with my terms... They are not separated between parent terms. I can only see Alimentation twice. (see with term store screen below)

  3. Finally, when submitting my form, with everything well filled, nothing happens. No items are created in my Case list. I then stop the app running to find a little cross on my submit button. And here it says the following error : "SectionMachine_RI : the specified column is generated by the server and can't be specified" => HOWSO? see the screenshots below :managedmetadata_error.PNG


    So here is my question : how should i make this work ? I am going to re-think my whole metadata termstore, but that is a bit of a bother.. And apparently one of my coworker could make it work with a reusable term. So i don't know where that comes from.
