Master tables for Order

Question

Hi,
In creation of MAINTENANCE ORDER, I need to create a Search help for Work Center and Plant based on :
1. Order type
2. Planning plant
3. Business area
Could you help me out by letting me know what are the master tables having these fields.

* Validate Work Centre
  if not ZES_PO_ITEM-ST_ARBPL is initial.
    clear : T399X.
    select single * from T399X where WERKS = ZES_PO_ITEM-ST_SWERK
                                 and AUART = ZES_PO_ITEM-ST_AUART.
    if SY-SUBRC = 0.
      call function 'CR_WORKSTATION_READ_ROUTING'
        exporting
          ARBPL = ZES_PO_ITEM-ST_ARBPL
          DATE  = SY-DATUM
          PLNTY = T399X-PLNTY
          WERKS = ZES_PO_ITEM-ST_SWERK."L_SWERK. "Changed on 27th Feb
