I have a feature class (Buildings) related to a table in a file geodatabase (Assets) (1-M RC). The Assets table has attachments of its own (PDFs): mean it has another table in RC with blob data that contain the PDFs.
The Building feature class is in a feature dataset and both relationship classes are in the feature dataset.
I have tried to publish the GDB a few ways (As A full GDB and as a feature service) into AGOL but I can't see the PDFs Attachments. Though I can see my related assets rows while pop-uping the feature's layer entities, I can not further related it to the attachment table and its contents.
My question is this: 1. How to see my PDF's using pop-ups interface in AGOL when interacting with the feature layer (Buildings)? 2. Alternatively, how to open attachments that is related to a stand-alone table in AGOL?
Further question: 1. Where does the attachments table is saved in the AGOL server? Why can't I see it?
