Rows to Columns conversion in an Internal Table

Hello All,

I have data like below:

Matnr1 ABC 100

Matnr1 ABC 200

Matnr1 ABC 500

Matnr2 XYZ 300

Matnr2 XYZ 600

I want data like this:

Matnr1 ABC 100 200 500

Matnr2 XYZ 300 600

Is it possible? If yes, could anybody help achieving this?

Thanks a lot in advance.

Ajay
