Break list based on company using CL_SALV_TABLE

Hi Experts,

I want to break the  ALV list based on the company code and that to using CL_SALV_TABLE class.

And before every list, header details should be display.

I know this can be achieved by SORT event in REUSE_ALV_LIST_DISPLAY.

Could not find solution to display using above class. I tried with ADD_SORT method with attribute GROUP field.

But list is not breaking when company code changes on list.

Please help me regarding this ?

Regards,

Siva
