I tested this on 2014 PU 4 and could not duplicate your results. I tested with SO Options equal to Yes, No and Actual for "Use Shipping Code to Calculate Freight". I tested with both complete shipments and partial shipments. Each test resulted in my freight charges etnered in Sales Order Entry being retained in Invoice Data Entry. You may want to check the setting in SO Options on the Entry tab. Then, check Shipping Rate Maintenance. Give us a call in Support if you're still experiencing this issue.

If you change shipping code in an invoice it can wipe out the freight amount (depending on options).  Perhaps that explains what is happening.

They are not on 2014 PU 4

I figured it out. I just need to make a change is sales order options. The problem is that we have sales people who need that functionality to take orders over the phone. So it looks like we will have to do it this way for a while.
