I asked a similar question here:

> [@DMT or SQL for UD](https://www.epiusers.help/t/dmt-or-sql-for-ud/68243):

> I do not go into the SQL side to ever write things in Epicor. I have plenty of external views that I have written to read, but I use BOs and DMT to do my data injections. That being said, I have a large amount of data that I need to put into a UD table. There are no customizations for DD or MD through BPMs on this table. Would it still be a no-no to use SQL injection to a UD table? In playing around in a sandbox, it takes about 6 minutes to load 500k+ lines of data. I don’t think DMT will …

Again, any direct injection is a “do it at your own risk” proposition.
