Can a user upload multiple large size assets within a PromotMats document?
A user can only upload one Large Size Asset rendition type within a document in PromoMats.
Large Size Asset is a special rendition type that supports files up to 100GB in size. These files are uploaded in PromoMats using the Vault File Manager to add or replace a new rendition to the target document.
If a rendition already exists within the same Large Size Asset rendition type, Vault replaces the existing file.
The user displays only the latest file uploaded through Vault File Manager in the Rendition section.
The new Large Size Asset added, overwrites all the other renditions uploaded previously as a Large Size Asset rendition type.
