How can i find the tablename for that field and suggest the report logic

Question

Hi experts
The concept of BOM for finished components are defined in terms of semi finished goods. Hence, routing of a component from raw materials can not be seen directly in system through standard report.
But users need to have the details of a routing of a component from raw material in one report. To provide the details in single report, development is required.
With this report users can see the routing from raw material till component in one single report.
Assumption
BOM is maintained for a component with all related semi finished components till raw material properly.
Material Number:  MARA – MATNR   - Multiple selection option should be there (Mandatory)
Plant: AFRU – WERKS      - Single selection parameter (Mandatory)
If procurement type is E or X, system has to check the routing through CA03.
If procurement type if F, leave this field as blank
1.operator
2.material
3.material description
4.workcenter
5.vendor
6.operation description
7.uom
8.qty
9.uom
10.setuptime
11.processingtime
12.deliverytime
using cs12,cs13
  here i have seen the details of finished goods components like semifinished goods,rawmaterils,i tried se11 to find the the table for relevent field,
i cant get, if possible to suggest me the logic and how to find the relevent table for
that field

Answer 1

for exploding the bom if you know header material use
  CALL FUNCTION 'CS_BOM_EXPL_MAT_V2'
    EXPORTING
      CAPID                 = 'PP01'
      DATUV                 = SY-DATUM
      MEHRS                 = 'X'
      MTNRV                 = P_MATNR
      WERKS                 = P_WERKS
    TABLES
      STB                   = I_BOM
    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.
now check PLPO & PLKO table for routing or AFVC and AFVV for routing.
if production order created you have to check in afvc and afvv else check in plpo and plko.
for checking with plpo and plko you have to check MAPL table.
for bom and material link
MAST,STPO,STKO.
stlnr is the common field
