System Error received importing I/C Receipt

Version 6.2 PU1 Sage 300 ERP SQL 2012

I exported an I/C receipt, copy data to it from another spreadsheet and tried to import it back in as a new receipt (i.e. changed the sequence #) and am getting the following error:

Description: System error. Write down the message, error and source codes. Exit Sage 300 ERP and Windows. Restart and retry the operation.
Code: 3.3841.0
Source:  18:15:07 - SvrView: IC0590

I have around 10,000 items to import and could really use some assistance with this.  Any ideas or tips would be appreciated.
