Mload on a referenced table. - response (3) by harishkshetty

Hi I am new to teradata, I am facing problem in MLOAD with respect to single column load.
my file contains
123
234
4567
678
 and my MLOAd utility is throwing error while reading the data from the file.
i am using the layout like this:
.layout alayout indicators; 
.field          a                         *     varchar(20);

.DML LABEL ADML;
INSERT INTO tbl1(
 a                            
)
VALUES
(
:a);
 
.import infile file1
format vartext
layout alayout
apply adml;
 
I am getting the erro:
UTY4015 Access module error '35' received during 'read' operation
     on record number '3': 'EOF encountered before end of record
 Please suggest me if any thing wrong in the script.
