How to build Field catalog when using CL_GUI_ALV_GRID
Dear Experts .
I am using CL_GUI_ALV_GRID for the ALV i have Z structure with 70-80 fields i want to build field catalog .
I can Use the FM REUSE_ALV_FILED_CATALOG_MERGE but table structure of this FM for field catalog and what i pass as field catalog to CALL METHOD g_alv_grid->set_table_for_first_display are of the different format .
How do i over come this ? is there any method where in i can build field catalog by passing the structure ?
