How to link between these tables and get the bom explosion

Question

tables : mast,stpo,makt
  SELECT AMATNR BMAKTX CIDNRK CMENGE C~MEINS  INTO CORRESPONDING FIELDS OF TABLE IT_COMP_IDEL FROM
                   MAST AS A INNER JOIN MAKT AS B ON AMATNR = BMATNR
                             INNER JOIN STPO AS C ON ASTLNR = CSTLNR
                   WHERE AMATNR IN S_MATNR AND AWERKS IN S_WERKS.
using cs13 to get the bom summary
using these table to but i got only few materials only,
but cs13 got more materials
how can i solve that one
Regards

Hi,
Just go through this program i think it will help u out.
TABLES: MARA, MARC.
TYPE-POOLS : fibs,stree.
TYPES: BEGIN OF STRUCT_BOM,
        MATNR TYPE MATNR,          " Material Number
        WERKS TYPE WERKS_D,        " Plant
        IDNRK TYPE IDNRK,          " BOM Item
        STLAL TYPE STLAL,          " Alternative BOM
        STUFE TYPE HISTU,          " BOM Level
        OJTXB TYPE OJTXB,          " Object description (assembly)
       END OF STRUCT_BOM.
*- table types
types: t_bom type table of struct_bom.
*Internal Tables to hold the BOM data.
DATA: ITAB_BOM type table of STRUCT_BOM.
DATA: WA_BOM TYPE STRUCT_BOM,
      wa_stb type stpox,
      wa_matcat type stpox.
DATA: IT_STB       type standard table of STPOX,
      IT_STBC      type standard table of STPOX,
      IT_MATCAT    type standard table of CSCMAT.
*-- to enter BOM DATA
*Selection Options
select-options: s_matnr for V_matnr,       "BOM Material
                s_plant for V_werks.       "BOM Plant
*Input Parameters
parameters:     p_alter type stko-stlal,      "Alternate BOM
                p_usage type stzu-stlan,      "BOM usage
                p_appli type tc04-capid,      "BOM Application
                P_CATE  TYPE STKO-STLTY DEFAULT 'M'.      "BOM Category
INITIALIZATION.
REFRESH ITAB_BOM.
CLEAR WA_BOM.
REFRESH IT_STB.
REFRESH IT_MATCAT.
START-OF-SELECTION.
SELECT matnr
       werks
       stlal
       INTO CORRESPONDING FIELDS OF TABLE itab_bom
       FROM mast
       WHERE matnr IN s_matnr
       AND werks IN s_plant
       AND stlan = p_usage
       AND stlal = p_alter.
CLEAR V_MATNR.
CLEAR V_WERKS.
DATA: WA_STB TYPE STPOX,
      WA_MATCAT TYPE CSCMAT.
    v_matnr = wa_bom-matnr.
    v_werks = wa_bom-werks.
    CALL FUNCTION 'CS_BOM_EXPL_MAT_V2'
      EXPORTING
        capid                 = p_appli
        datuv                 = sy-datum
        mktls                 = 'X'
        mehrs                 = 'X'
        mtnrv                 = v_matnr
        stlal                 = p_alter
        stlan                 = p_usage
        werks                 = v_werks
      TABLES
        stb                   = it_stb
        matcat                = it_matcat
      EXCEPTIONS
        alt_not_found         = 1
        call_invalid          = 2
        material_not_found    = 3
        missing_authorization = 4
        no_bom_found          = 5
        no_plant_data         = 6
        no_suitable_bom_found = 7
        conversion_error      = 8
        OTHERS                = 9.
    IF sy-subrc <> 0.
      MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
              WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    ENDIF.
Then just print whatever data u want it_stb, it_matcat tables.
reward points if u find my answer helpfull.
