Same situation here which is really lame… just started happening around the time you put this post up. We have 10k+ attachments on two tables. Epicor doesn’t have a good workaround… best they came up with was to create a new sharepoint site every time you reach the max which kinda defeats the purpose of putting the docs in sharepoint in the first place for us.
Still not sure what we are going to do. For the time being I made another document type for the two tables that reached the max which uses a networked file share instead.
BTW, “classic” Document Libraries have the 5000 limit but the Modern Document Library is higher. Nonetheless, SharePoint was certainly not designed to be a dumping ground…
@Mike we didnt create site. we instead renamed the “APInvHed” folder in sharepoint as “APInvHed2” and updated the filepath reference on table xfileref from “APInvHed” to “APinvHed2” via a updatable dashboard. works fine.
