Hi Manny,
Sorry for the trouble caused at your end.
From the description provided, I understand your concern based on my test and I would like to summarize for misunderstanding:
a. You created a Document Set Content type with some columns and added it to the Document Library.
b. You created the Document Set and created documents in the Document Set folder.
c. When you select the multiple documents in the Document Set folder and click on Open the details pane, you can see only Content type and columns created in the Document Library (not the columns added to the Document Set Content type).
If my summary is correct, even at our end during the test, we cannot see the site columns added to the Document Set Content type in Open the details pane for the documents in the document library. My assumption, the metadata we added
to the Document Set Content type is only for the Document Set folders created but not for the documents created inside the Document Set folder or Document Libraries.
You can see the metadata in the Bulk Edit when you select the Document Set Folders in the Document library instead of Documents. We found a workaround, where we can add the metadata to the document via
Edit in grid view.
Appreciate your understanding and patience. Have a good day and stay safe!
😊
Best Regards,
Chitrahaas
