Question: I have a requirement to "electronically" approve documents in SLX and then once approved they become read-only. Just wondering what would be the best way to accomplish this. Do I convert to a PDF and save to an attachment folder and password protect these when saving? Or can I stream the document into a blob field which I don't allow updating. Or are there other options you can suggest? Answer: The quickest way is to stream/de-stream into a blob - you can guarantee r/o in this way.
