select  ZC~CUSTID
          ZC~CUSTFNAME
          ZO~PRODUCTID
          ZP~PRODNAME
        from  ZCUSTPROFILE as ZC
        join   ZORDER as ZO
           on ZOCUSTID = ZCCUSTID
        join  ZPRODUCT as ZP
           on ZOPRODUCTID = ZPPRODUCTID
      into corresponding fields of table ITAB        <b>" < when u mentioned in the same order not need of corresponding .. this might be a peformance issue later</b>
      where ZC~CUSTID = 3.
loop at ITAB into WA.
  write: / WA-CUSTID, WA-CUSTFNAME, WA-PRODUCTID, WA-PRODUCT.
endloop.
