Hello hridhayanjili
SAP provides us with the ABAP statement <b>COLLECT</b> to summarize totals.
I will give you an example from which you should be able to develop you own solution.
Let's assume we have an itab containing materials. The itab has the following line structure: MANDT, MATNR, QUANTITY. To calculate subtotals we require a second itab that is identical to the first one.
Now here is the coding:
data:
  gt_itab          TYPE STANDARD TABLE OF <structure>,
  gt_itab_collect  TYPE STANDARD TABLE OF <structure>,
  gt_itab_total    TYPE STANDARD TABLE OF <structure>.
  gs_entry         TYPE <structure>.
* NOTE: <structure> stands for a named DDIC structure or
* a type definition, not a field symbol.
* gt_itab contains our materials
  LOOP AT gt_itab INTO gs_entry.
    COLLECT gs_entry INTO gt_itab_collect.
  ENDLOOP.
* NOTE: Assuming we had 10 entries in gt_itab of
* 3 different materials we end up with 3 entries in
* gt_itab_collect that contain the quantities summarized.
* To calculate the total one could LOOP over
* gt_itab_collect and summarize the values. Another way
* is shown here:
  CLEAR: gs_entry-matnr.
  MODIFY gt_itab FROM gs_entry
    TRANSPORTING matnr
    WHERE ( matnr IS NOT INITIAL ).
* We clear the material no.
  LOOP AT gt_itab INTO gs_entry.
    COLLECT gs_entry INTO gt_itab_total.
  ENDLOOP. 
* NOTE: because we have the same value for CLIENT and
* MATNR in every line we will end up with a single line
* in gt_itab_total.
Please read the documentation of the COLLECT statement carefully because the structure of your itab (i.e. the order of the fields, especially those that will be summarized) is important.
