1. You need 2 internal tables: FIELDCATALOG table and SORT table
DATA: gt_fieldcatalog TYPE lvc_t_fcat,
gt_fieldcatalog_sort TYPE lvc_t_sort,
lw_fcat TYPE lvc_s_fcat,
lw_fcat_sort TYPE lvc_s_sort.

2. Fill fieldcatalog table fields
lw_fcat-fieldname = 'YOUR FIELD NAME'.
* Subtotal for this field
lw_fcat-do_sum = 'X'.
APPEND lw_fcat TO gt_fieldcatalog.

3. Fill sort table fields
* Mark the fields that you want to make subtotals after
(e.g. VKORG KUNNR VBELN = keys ; NETWR = sum)
CASE 'YOUR FIELD NAME'.
WHEN 'VKORG' OR 'KUNNR'.
lw_fcat_sort-fieldname = u_fieldname.
lw_fcat_sort-up = 'X'.
lw_fcat_sort-subtot = 'X'.
APPEND lw_fcat_sort TO gt_fieldcatalog_sort.
WHEN OTHERS.
ENDCASE.

Risult
VKORG | KUNNR | VBELN |NETWR
1 a 001 10
1 a 002 20
1 a 003 30
----------------------------
subtotal 1 a 60
----------------------------
1 b 001 5
----------------------------
subtotal 1 b 5
----------------------------
