in Read_text FM, the data after 256 characters gets truncated

Hi All,

In this FM, the internal table can't have string type field. In my case the data is in multiple lines of internal table and I am concatenating into a single field which is of type DESCRIPTIONS(string). I am passing this data to a table in smartform.Only 255 characters are printed, remaining data gets truncated. I am using CONVERT_OTF and SX_TABLE_LINE_WIDTH_CHANGE FMs to create PDF. Is it the limitation or I am incorect here?
