IMPORT CSV to a table view

[Hussein_Osseily]

Good day everyone, 

I have a table that is using the row number as a KEY with the following columns : 

Shipment Number
Shipment Status 
PCS
WEIGHT
Volume 

I am trying to upload a csv file that has the following columns: 

_RowNumber

PCS
WEIGHT
Volume 

When i choose to import , i get the following error:  

ErrorDescription: Row key field '_RowNumber' value is missing

Even though the '_RowNumber' column is in the csv file and is not blank 

I am missing something here ? any suggestions would be really appreciated 

Thanks
