hi ,

plz tell me how to add f4 help functionality to a text field in a screen in module pool program. ie., the input should be given by selecting from the list of entries from the database table for that particular field.

Thanks & Regards,

Syam.

For Getting the F4 Help in Module pool

1. we have to use Flow logic event POV

Assume that you have a field on screen CARRID

PROCESS ON VALUE-REQUEST.

FIELD CARRID MODULE VALUE_CARRIER.

2. Implement the Module.

MODULE value_carrier INPUT.
"First get the Data to an internal table from some ZTABLE or standard table. then you have to pass the table to this function.
  SELECT  carrid connid
    FROM  spfli
    INTO  CORRESPONDING FIELDS OF TABLE values_tab
    WHERE carrid = field_value-fieldvalue.

  CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
       EXPORTING
            retfield    = 'CARRID'  "<---retun field from table
            dynpprog    = sy-repid
            dynpnr      = sy-dynnr
            dynprofield = 'CARRID' " <---screen field
            value_org   = 'S'
       TABLES
            value_tab   = values_tab. "<---Internal table for F4 help

ENDMODULE.

follow the steps and Provide the F4 for your fields.
