Using CL_RSR_WWW_MODIFY_TABLE to remove rows completely from output!

Question

Hello All,
I have a problem I am trying to work thru and I need some assistance.
Here is the issue...
I have a report, in which I want to completely remove uneeded rows (depending on the contents of the row).
I have had a look thru the how-to papers on the TAble interface (so please don't post links to those, they are not what I am searching for as they only describe things like not displaying cell contents, and like I stated, I want to not show rows...ie, delete them from output.)
Does anyone have some code to show me how to accomplish this?
Here is my scenerio...
I have a query, from the 0IC_C03 infocube (I understand the IM scenerio, so don't post links to the SAP help for How-to on this subject), and in the query, I have storage location and material. As we all already know, the infocube does not give a good solution to provide values only on Storage location. But, to get around this, you can have a report with Material in the rows, and do a calculation (Price * Qty) to get the totals by storage location. But, I do not want to show the materials. (Yes, I know there is yet another how to paper on realizing inventory on storage location level, but that does not produce correct results).
The query is doing exactly what I want...here is the results.
STORLOC____MATERIAL_____VALUE
<b>LOC1________RESULT_______$200000</b>
LOC1________MATNR1_______$150000
LOC1________MATNR2_______$50000
<b>LOC2________RESULT_______$2500</b>
LOC2________MATNR3_______$1500
LOC2________MATNR4_______$1000
<b>LOC3________RESULT_______$500</b>
LOC3________MATNR5_______$500
You get the idea...
Anyway, I want to turn the above, into the following..
STORLOC____MATERIAL_____VALUE
<b>LOC1________RESULT_______$200000
LOC2________RESULT_______$2500
LOC3________RESULT_______$500</b>
Essentially, removing everything but the results rows...
Now, I have read a few other questions out here on something similiar (someone else was trying to accomplish the same thing) but nobody has ever posted a reasonable answer to the above question, so I am hoping, some of you have a solution, either via defining my own CL_RSR_WWW_MODIFY_TABLE solution or via Javascript.
If someone has accomplished this with the table interface, which method and how did you change the table?
If someone has accomplished this with javascript or something else, I would like the details of that as well.
Note: I was able to read the table, and was able to use a temp table, and remove the rows I did not want, but, I was not able to update the table passed by the interface.
This code works to get the right rows, but, it doesn't allow me to update the passing table.
DATA:wa_y_axis_data LIKE LINE OF
  I_r_data_set->n_sx_version_20a_1-axis_data,
  wa_cell_data LIKE LINE OF
  I_r_data_set->n_sx_version_20a_1-cell_data,
  set LIKE LINE OF wa_y_axis_data-set,
  TUPLE_ORDINAL like set-TUPLE_ORDINAL,
  l_counter TYPE i,
  l_index TYPE sy-index,
  l_trade_fvalue LIKE wa_cell_data-formatted_value.
* prerequesite in example: 1 key figure and 1 calc. key figure column
LOOP AT I_r_data_set->n_sx_version_20a_1-axis_data INTO wa_y_axis_data
  WHERE AXIS = 1.
  LOOP at wa_y_axis_data-set into set.
   l_index = sy-index.
   if set-chanm = 'A0MAT_PLT' AND set-chavl NE 'SUMME'.
     delete wa_y_axis_data-set where tuple_ordinal = set-tuple_ordinal.
   ENDIF.
  ENDLOOP.
ENDLOOP.
Any similiar experiences or feedback is appreciated.
Cheers!

Hi Steve,
just want to know why the material has to be present in this report - when not shown in the end - just to have it in the column or why wonder?
