Uploading long text using LSMW

Hi Wizards,

Could any of you kindly tell me how to upload multiple lines of long text against the same material code? My client requires upload of long text comprising more than 500 characters in material master but the max character length permitted per line is 132.

I have tried to do with multiple line items against the same material code in my flat file but only the last line shows overwriting the previous lines. Kindly help.

Thanks and regards,

Abhik
