Answer 1

When u call a BAPI there will be Return structure. u need to pass the internal table to that function module. when the function module is executed the internal table is filled with the messages. u can loop at that internal table where message type is 'E' and process the message.
Check this :
DATA:IT_PERSONALDATA LIKE STANDARD TABLE OF BAPIKNA101_1 WITH HEADER LINE,
     IT_COPYREFERENCE LIKE STANDARD TABLE OF BAPIKNA102 WITH HEADER LINE,
     RETURN LIKE STANDARD TABLE OF BAPIRETURN1 WITH HEADER LINE.
CALL FUNCTION 'BAPI_CUSTOMER_CREATEFROMDATA1'
  EXPORTING
    PI_PERSONALDATA              = IT_PERSONALDATA
  PI_OPT_PERSONALDATA          = PI_OPT_PERSONALDATA
  PI_COMPANYDATA               = PI_COMPANYDATA
  PI_OPT_COMPANYDATA           = PI_OPT_COMPANYDATA
  PI_CONSUMEREN                = PI_CONSUMEREN
    PI_COPYREFERENCE             = IT_COPYREFERENCE
  PI_CREDIT_CONTROL_FLAG       = PI_CREDIT_CONTROL_FLAG
IMPORTING
   CUSTOMERNO                   = V_CUSTOMERNO
   RETURN                       = RETURN.
CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'
  EXPORTING
    WAIT = 'X'.
APPEND RETURN.
LOOP AT RETURN.
  WRITE:/ RETURN-TYPE, RETURN-MESSAGE.
ENDLOOP.
