Hello Nils,
Thank you for your reply..
The XML which I want to upload has more than 50,000 records.To validate the XML, I kept only 3-4 records and deleted rest of them and uploaded. It was successful.
Kindly let me know If there is any other way to validate xml.
Size of the file which i want to upload is 969KB (records more than 50,000)
Regards
