When you have a File Attachment type field in the launch form, these attachments do not get added as Additional Documents in the workflow. Instead, the user needs to wait until the workflow is in the Review step and then add it as an Additional Document.
The use case is if we have a workflow with Company Paper, but also want to collect some Counterparty paper at the same time (using File Attachment). If you need to redline/edit this Counterparty Paper, it needs to be added as an Additional Document.
For example, we have a Procurement workflow for Consultants. The paper source is My Company’s Paper & Counterparty Paper. This is to allow for the situations where the consultant is fairly professional & has a Consulting agreement they use for all their clients and also for sporadic freelancers that defer to our Company template paper.
But there are a bunch of times where the consultant has an SOW or Order Form that they use, but since that is insufficient as a contract, we add that as Appendix to our Company template paper.
