Hi Nagarajan & Nick
Thanks for the assistance.
I didn't know about templates in DTW - I was just using excel sheet and using 'View>System Information' to try and work out headers.
So now you have pointed me to templates I have found OITM template and got correct information for header cells.
Several thousand records were updated with only one error:
ERROR:
A positive value is required [OITM.TreeQty], 'TR 230-M24X1.5' Application-defined or Object-defined erroroItems
If possible can you suggest what the problem was?
I compared that Item to other successful items and cannot see what is difference..
Thanks
Karen
