FM for knowing the required qunatity

Question

Hi all ,
I have a finished good (material number ) with me .
It is made up of different semi-finished and raw materials .
Suppose i need 1000 quantity , and finished good is not available ....
I need to know how much of these semi finished and raw materials are required to make the finished good .
Is there any FM , which tells us the quantity of semi finished and raw materials required for a given input ....
Let me know any process is there if no FM is available ..

Answer 1

Usually they are known as Bill of Materials, where the First level of finished goods is made of semi finished goods & Raw material. Semi finished goods can also be made of Raw material.So, for the Finished goods you may require all the material which are required in production.
Look at CS_BOM_EXPL_MAT_V2
call function 'CS_BOM_EXPL_MAT_V2'
    exporting
      ftrel                 =  ' '
      capid                 = 'PP01'  --> it depends on the BOM
      datuv                 = p_date --> Current date
      emeng                 = 1
      mehrs                 = 'X'
      mtnrv                 = matnr  --> Material
      stlan                 = stlan   --> This value you need to get from MAST table by passing Material & Plant
      werks                 = werks --> Plant
    tables
      stb                   = t_stb --> this will be the OUTPUT table
    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.
Above Function module is for multiple level and you can also retrieve data from joining MAST & STPO tables.
