field exit check not triggering

Former Member — Sat, 21 Jun 2008 06:00:58 GMT

hi experts,

I want to put check on quantity field of goods movement screen of co11n transaction if material exists.

I am using the fiedexit & below code to read values & put check.

DATA: i_dynfields TYPE TABLE OF dynpread WITH HEADER LINE,

num TYPE i,

v_erfmg TYPE mb_erfmg.

DO 11 TIMES.

num = sy-index.

i_dynfields-fieldname = 'MATNR'.

i_dynfields-stepl = num.

APPEND i_dynfields.

i_dynfields-fieldname = 'ERFMG'.

i_dynfields-stepl = num.

APPEND i_dynfields.

ENDDO.

ENDIF.

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

dyname = 'SAPLCOWB'

dynumb = '0500'

translate_to_upper = 'X'

REQUEST = ' '
PERFORM_CONVERSION_EXITS = ' '
PERFORM_INPUT_CONVERSION = ' '
DETERMINE_LOOP_INDEX = ' '

TABLES

dynpfields = i_dynfields

EXCEPTIONS

invalid_abapworkarea = 1

invalid_dynprofield = 2

invalid_dynproname = 3

invalid_dynpronummer = 4

invalid_request = 5

no_fielddescription = 6

invalid_parameter = 7

undefind_error = 8

double_conversion = 9

stepl_not_found = 10

OTHERS = 11

IF sy-subrc <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

LOOP AT i_dynfields.

IF i_dynfields-fieldname = 'MATNR'.

IF i_dynfields-fieldvalue IS NOT INITIAL.

READ TABLE i_dynfields WITH KEY fieldname = 'ERFMG'

stepl = num.

IF sy-subrc EQ 0.

IF i_dynfields-fieldvalue = 0 OR

i_dynfields-fieldvalue = space.

MESSAGE e004(zmsg2) WITH 'Quantity cannot be zero or empty'.

ENDIF.

ENDLOOP.

ENDFUNCTION.

but this is not executing the error message.

pls tell me where it is wrong.

LOOP AT i_dynfields where fieldname = 'ERFMG'

and stepl = num.

IF sy-subrc EQ 0.

IF i_dynfields-fieldvalue = 0 OR

i_dynfields-fieldvalue = space.

MESSAGE e004(zmsg2) WITH 'Quantity cannot be zero or empty'.

ENDIF.

ENDLOOP.

it is solved i need to pass entire screen field instead of 'matnr' ie. 'COWB_COMP-MATNR'.

but now the code is displaying error when quantity is not equal to zero also.

may be type mismatch.

can anyone tell?
