Issue with ALV Grid display not displaying the field catalog

Hello Experts,

I am adding new fields at the standard report output ME2A RM06ENBE. I had added new fields in structure MERE_OUTTAB_ME2A and the REUSE_ALV_GRID_DISPLAY fm  that is used in report is using i_structure_name and so no field catalog need not be created.

the new fields added are present in the final internal table gt_outtab .... how can I make those fields  display at the output.

Thanks,

Balu
