Schema import mapping cannot be edited

[Liu_ Ray]

For the existing import mapping, under mapping, edit attributes mapping, how can we edit the Data source field?

Need to make some adjustments, but when editing the Data source field, it's showing a dropdown and showing "no options".

Hi @Liu_ Ray , thanks for your post.

Please can you share some screens of what you are seeing?

I have understood you are here

and you don't see the correct data in the source field. These are the columns from the file you are trying to load so if you need to import other attributes, you would need to add them to the source file, or do I not understand?

Please can you show what the issue is so we can help you troubleshoot?

Thanks

Hi Valerie, thanks very much for your reply!

I wasn't able to insert screenshots sorry about that, but you're showing the exact right place. 

THe only difference is I am using external import type, the mapping was originally uploaded as JSON file (the original JSON file was lost so we prefer to modify the mapping on GUI).  The drop-down just shows no options.

Hi @Liu_ Ray , thanks for your reply.

If the original file that you are trying to import from was lost, maybe this is a silly question, but what is the file source?

The mapping can only suggest to map to the Assets fields the columns / data that are found in the source file.

Hi Valerie,

I mean the file for mapping schema was lost, so I cannot just upload a new schema to cover the existing one. The asset import was done via API.

Back to the original question, in the screenshot, why the Data Source field drop down is empty?
