While parsing Flat file to XML, you got below error, if you have special white space characters.
Unable to store data, error copying stream.; Caused by: Failed generating xml document; Caused by: Invalid white space character (0x3) in text to output
To solve the issue, use data process step after getting the data from source system(Disk, FTP, SFTP).
Select search/replace option and use below syntax,
Search : \u0001
Search : \u0003
Replace with empty space then you won't see that error.
