Reading a flat file

I get the following error when reading a flat file : [Credit Information 1 [1]] Error: Data conversion failed. The data conversion for column "AccountName" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".

I did check all the mappings, and everything seems to be fine, the field is read in as a string. I also check for any strange characters that can possibly cause this error but the value of the field only contains a person's name and spaces at the end.

Does anyone have any ideas what might be the cause of the error?What is the source data type of the AccountName field?

What is the data type of the mapped field in SSIS?
