IS the file content conversion using SFTP adapter is restricted to read only 44 columns?

Hi Friends,

My interface Uses a SFTP sender channel with file content conversion which reads the data from csv/text file.

I am unable to the data after the 44th column.I am getting the error as below

Error : Exception received: com.sap.aii.adapter.sftp.ra.rar.conversion.exception.XmlGenerationException: XML creation failed due to: org.w3c.dom.DOMException: INVALID_CHARACTER_ERR: An invalid or illegal XML character is specified.

Thanks in Advance
