Updating UD Field in Sales Order Release Table

I found this solution that worked!

All I had to do was change to:

rel["Character01"] =  BpmFunc.Now() + "--- System manually updated release " +  MyRel + " in order " + MyOrder + " on line " +  MyLine + " Old Date: " + DateOld + " New Date: " + DateNew + " Old Qty: " + rel.OurReqQty + " New Qty: " + xRow.OrderRel_OurReqQty;

Thanks @hkeric.wci!
