You must add the specific field names to the TABLE before calling the function module, this will tell the FM which fields to get the values for. You must fill the fieldname into the TABLE that you want to get the value of.



data: table like DYNPREAD occurs 0 .
<b>data: wa like line of table.</b>


<b>wa-fieldname = 'A_FIELD'.
append wa to table.</b>

CALL FUNCTION 'DYNP_VALUES_READ'
    EXPORTING
     <b>DYNAME = sy-repid
        dynumb = sy-dynnr</b>
    tables
        dynpfields = table.

It would appear that the field name FKDAT is not valid for that screen, make sure that it is the valid name of the field on the screen and that it is in the right screen number, it could be that it is in a subscreen which would have a differnt screen number, in which case you may have to hardcode the screen number when calling function module as you have done to start with.

First, check that FKDAT is the valid field name. Check the screen number and program name that you are passing.
