Hi,

We are uploading documents via this API but the files are appearing in the Incoming Document Files section and not the Attachment Section, after checking and debugging I learned that there are 2 tables for attachment, one is Document Attachment (The AttachmentTab) and the other one is Attachment, the API will create in the second one, any ideas how to create files in the Document Attachment Table from the API?

Hi, if you are using the standard API, unfortunately, only Incoming Document (table 130) is supported so far.

More details: https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/api-reference/v2.0/api/dynamics_attachment_get

If you want to use Document Attachment, this requires a custom API.

Hope this helps.

Thanks
