Last row content in an hashed table

I want to know the content in last row of my Hashed table.

I tried like this:::

Describe lt_itab lines sy-tfill.

Here I got my number of rows, using this row number I want to read the last row content of my hashed table.

We can use a READ lt_itab index sy-tfill as this is a Hashed table.

My hashed table does not have any index field.

Suggest me some simple solution to achieve good performance.
