Did you enable the object connection service for document connections for purchase order lines?
Hi @Mathias Dahl,
I added a line in the object connections and in the object connection transformations, and I can now add documents.
Thanks a lot!
Hi @TheoB
Great that you were able to sort it out. FYI, what made it work was the change you did in Object Connections.
Object Connection Transformation is a related piece of functionality but it is not used to enable document attachments (it's documented in great detail in the documentation, so I will not repeat it here).
