Problem of function module 'DYNP_VALUES_READ'

[Former Member]

Hi buddies,

I used the FM 'DYNP_VALUES_READ' to catch the value of one screen control at the event 'AT SELECTION-SCREEN ON VALUE-REQEUST'.After I inputed value in the control 'P_WERKS' and triggered the event, there is no values in the internal table 'lt_fields' which should be stored the values of all the screen controls.

REPORT  zdyntest001.

PARAMETERS: p_werks TYPE werks_d,
            p_lgnum TYPE lgnum.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_lgnum.
  DATA: lt_fields TYPE TABLE OF dynpread.
  CALL FUNCTION 'DYNP_VALUES_READ'
    EXPORTING
      dyname     = sy-repid
      dynumb     = sy-dynnr
    TABLES
      dynpfields = lt_fields.
  IF sy-subrc = 0.
    BREAK-POINT.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
            WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ENDIF.

Hi,

You have created table without header line.

Do like

data : wa like dynpread.

wa-fieldname = 'P_LGNUM'.

append wa to lt_fields.

clear wa.

now call function module.

read table lt_fields into wa with key fieldname = 'P_LGNUM.

Assign wa-fieldvalue to variable.

Hi Vincent,

There are also two function modules - DYNP_VALUES_READ and DYNP_VALUES_UPDATE - that can read the values of screen fields and return values to them during the POV event. For further information, refer to the relevant function module documentation.
