Sending document in CSV format via email

Hi,

I need to send the document in CSV format via Email but the problem is the length of each row is more than 255 characters(around 450 characters) but all standard function modules will accept only the length of 255 characters for each row (document OBJBIN) in Tables parameter.I already checked few SAP standard function but all of the function accept data in 255 characters. Please provide the solution as early as possible.
