How to move dublicate records from one internal table to another table

Hi Experts,

I have internal table. In that internal table i have 3 fields.

MATNR MTART MENIS

TESTMAT ZHLB M

123te ZHLB M

123te ZHLB M

123te ZHLB M

ABC HALB M

ZYX FERT M

9620075 ZHLB M

9620075 ZHLB M

Here i need to move the material into another internal table which comes more than once. That means here i need to move 123te and 9620075 into another internal table.

Can any one help this?
