Let's say the selection screen has two input fields. One is plant i.e., PA_WERKS and other one is object(PA_OBJ). While executing the report, User will first enter the plant name in the WERKS field. Then, he will press F4 at the PA_OBJ field. It should dynamically take the value from PA_WERKS and display the possible values on F4 dialog box by searching in the table ZAIS_MMG.

Solution is written below and all the comments were provided at necessary places. Table need not be necessarily ZAIS_MMG. This logic is used for any table where you just need to change the table name.

Below is the subroutine that needs to be called at seelction screenAT SELECTION-SCREEN ON VALUE-REQUEST FOR pa_obj.

&----

*& Form object_f4help

&----

Provides the possible values for pa_obj

----

--> p1 text
<-- p2 text

----

FORM object_f4help.

Refresh the internal table. This helps in reusing these tables and variables in * other subroutines.

CLEAR: tb_dynpfields,

tb_object_range.

REFRESH: tb_dynpfields,

tb_object_range.

Define Internal tables.

DATA: tb_dynpfields LIKE dynpread OCCURS 0 WITH HEADER LINE.

Define constants.

CONSTANTS: co_retfield TYPE dfies-fieldname VALUE 'OBJECT',

co_dynprog LIKE sy-repid

VALUE '/DCSEA/Z_AIS_NUM_RESET_PAJERO',

co_s TYPE c VALUE 'S',

co_field(27) TYPE c VALUE 'PA_OBJ'.

Assigning the values of program name and screen to the variables.

wf_dyname = sy-repid. " PROGRAM NAME

wf_dynumb = sy-dynnr. " SCREEN NUMBER

wf_dynpro = co_field.

Move the field name to tb_dynpfields.

MOVE 'PA_WERKS' TO

tb_dynpfields-fieldname.

APPEND tb_dynpfields.

Read screen field values before PAI field transport. This FM is used for dynamically * reading a value from the selection screen field .

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

dyname = wf_dyname

dynumb = wf_dynumb

TABLES

dynpfields = tb_dynpfields

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.

Read the tbale tb_dynpfields to read the dynamic value of pa_werks

READ TABLE tb_dynpfields INDEX 1.

IF sy-subrc = 0.

wf_werks = tb_dynpfields-fieldvalue.

ENDIF.

Populate the table tb_object_range. Make sure that we filter out null values as it * might appear on the screen.

SELECT werks object

INTO TABLE tb_object_range

FROM zais_mmg

WHERE werks EQ wf_werks

and object NE ' '.

Sorting is always done before dlete adjacent duplicate.

sort tb_object_range.

This will delete all duplicate entries. Or else when you press F4, it will display * the duplicates also.

delete adjacent duplicates from tb_object_range comparing object.

F4 help also returning the value to be displayed in internal table. If the internal table is empty, it will display the message saying 'Values are not found'.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = co_retfield

dynpprog = co_dynprog

dynpnr = sy-dynnr

dynprofield = wf_dynpro

value_org = co_s

TABLES

value_tab = tb_object_range

EXCEPTIONS

parameter_error = 1

no_values_found = 2

OTHERS = 3.

IF sy-subrc <> 0.

MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

ENDIF.

ENDFORM. " object_f4help

Use the data element 'BUKRS' for that field when creating your Ztable.

This will automatically provide F4 help for ur field.
