The Entity Document Add workflow action lets you add documents to any entity using a workflow. There are a few things to keep in mind when you’re doing this. Each Document Type is associated with both an entity and a File Type. This means your workflow might get tripped up if it’s working with the wrong type of entity or with a file that doesn’t align with the File Type configuration. For instance, if the Document Type is configured for the Group entity, and if your workflow is trying to add a document for a Person, it won’t work. The workflow entity and the Document Type entity must match or else you’ll get an error. Similarly, the document you’re trying to add needs to conform to the File Type configuration for the File Type that’s associated with the Document Type you’re using. This will probably only be a concern if the File Type configuration has Preferred File Settings that are required. For someone to upload a Person document they need Edit access to both a Person Document Type and the File Type Person Document. Lastly, don’t be surprised if you’re able to add a document in cases where you think you shouldn’t be able to. For instance, the Media File File Type that ships with Rock is intended to be used for audio or video files but there’s nothing stopping you from adding a Word document using that File Type.
