Link foreign key your Ztable (BUKRS) and T001(BUKRS) table.

That time automatically F4 available.

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

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'

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

This will automatically provide F4 help for ur field.
