Substance Restriction on packing slip

We are trying to get the “compliance status” from Substance Restriction to show up on the packing slip. I could probably join a few tables myself but I noticed that the PackSlip RDD already has a SubstRestriction table. Epicor Support told me it is a temp table so it can’t be used in a relationship, so I’m not sure how to pull the information into report. Anyone done something similar?
