Display subtotal text in ALV grid

By Joyjit Ghosh,
Kolkata, India.

Steps:
• Declare the fields twice in the table structure on which subtotal needs to be calculated.
• Populate these fields with same values in the internal table.
• When populating field catalog with these fields, hide one of the field by populating no_out = ‘X’ and tech = ‘X’ in the field catalog.
• Populate alv sort table for the field which is hidden in the field catalog.
• Populate alv event table for subtotal text (slis_ev_subtotal_text) event with routine name.
• Define the routine in the program to display subtotal text.
