Stock Analysis

Question

Hi Experts,
I am doing a report on stock analysis,
And I am in trouble for one of the field ' Po quantity ' which is calculated
by , sum of  ekpo-menge and substracting it from ekbe-menge which is
[ movement type ( 101 ) - (102)  is ekbe-menge] .
Both ekpo and ekbe  is based on the matnr  from mard  table.
Finally I got the answer.... but only for few records the report is generated that to taking lots of time
and for huge records its showing dump error.
Please advice me is there any other method to calculate this Po quantity else guide me in correcting this error.
Thanks

Wow - that is a lot of data.  I hope you have some WHERE clauses in your actual code, as what you have written will bring back A LOT of data.
Here's some ideas:
1) If you aren't using any data from MARD to slim your query (a WHERE statement against a MARD field) I would use MARC.  This is the material per plant, whereas MARD goes to the storage location level (LGORT).  If you have multiple storage locations per plant, this multiples your data.
2) Don't do a SELECT * - you're bringing back way to much data from the tables.  Bring only the fields you need.
3) Move your SQL queries to more INNER JOINS and bypass some of the loops.
4) For your WHERE statement, it's probably worth doing a dynamic WHERE clause based on the user's choice for the radio-button re: open orders vs. PO balance.
For instance here's something I tried, and it works:
TABLES: mara.
TYPES: BEGIN OF typ_item,
         matnr TYPE matnr,
         werks TYPE werks_d,
         menge TYPE etmen,
         wemng TYPE weemg,
       END OF typ_item.
DATA: gt_item TYPE TABLE OF typ_item,
      gs_item TYPE typ_item,
      gt_where TYPE TABLE OF string.
SELECT-OPTIONS: s_matnr FOR mara-matnr,
                s_mtart FOR mara-mtart.
PARAMETERS: r_open RADIOBUTTON GROUP rad1,
            r_bal  RADIOBUTTON GROUP rad1.
START-OF-SELECTION.
  APPEND 'MARA~MATNR IN S_MATNR' TO gt_where.
  APPEND 'AND MARA~MTART IN S_MTART' TO gt_where.
  CASE 'X'.
    WHEN r_open.
      APPEND 'AND EKET~WEMNG = 0' TO gt_where.
    WHEN r_bal.
      APPEND 'AND EKETMENGE GT EKETWEMNG' TO gt_where.
  ENDCASE.
  SELECT mara~matnr
         marc~werks
         SUM( eketmenge ) SUM( eketwemng )
         INTO TABLE gt_item
         FROM ekpo INNER JOIN mara ON ekpomatnr = maramatnr
                   INNER JOIN marc ON ekpomatnr = marcmatnr
                                  AND ekpowerks = marcwerks
                   INNER JOIN eket ON ekpoebeln = eketebeln
                                  AND ekpoebelp = eketebelp
        WHERE (gt_where)
        GROUP BY maramatnr marcwerks.
  LOOP AT gt_item INTO gs_item.
    WRITE:/ gs_item-matnr, gs_item-werks, gs_item-menge, gs_item-wemng.
  ENDLOOP.
Hope this helps,
Mark
