Can you clarify what you mean by this? How are you reading the fields before hand? Are you talking about the DataSet itself? If so that makes sense since the business object data set that is “shipped” with epicor is the base dataset, and any additions are added by you / your company they won’t be reflected until the business object interrogates the server.
Also, for Copy to Excel, we found Char(13) is the problem. if contents such as PartDescription includes Char(13), the column got shift in 10.2. it is not the case in 10.1
