Hi Nagraj,
If several alternative BOMs exist, there is no possibility
of selecting the desired BOM interactively. Instead,
selection can be controlled via the following mechanisms:
- SELECTION BY QUANTITY:
  A lot size interval for which the BOM is valid can be
  entered in the BOM header.
  A prerequisite is that the Selection method indicator is
  not set in the material master record (MRP 4 view).
- SELECTION BY DATE:
  Can be set in the IMG under Production -> Basic Data ->
  Bill of Material -> Alternative Determination -> Define
  Alternative Determination for Multiple BOMs (transaction
  OS32). A prerequisite is that the Selection method
  indicator the is set to 1 in the material master record
  (MRP 4 view).
- SELECTION BY PRODUCTION VERSION:
  Can be used if the same material has different BOMs with
  different suppliers.
  You create different production versions in the material
  master record of the assembly (pushbutton in MRP 4 view)
    and assign an alternative BOM to the versions on the
  detail screen. You then enter the valid production
  version in the info record in each case.
If NO selection mechanism has been defined and several
alternatives exist, the FIRST one found is pulled.
