u need to create a search help on the first field and then when u press enter u get the value in the next field.

check out this example.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_DOC.

CHECK NOT SO_DOC IS INITIAL.

SELECT BSART FROM EKKO INTO TABLE I_TYP

WHERE EBELN IN SO_DOC.

SORT I_TYP BY BSART.

DELETE ADJACENT DUPLICATES FROM I_TYP.

CLEAR:VALUE_TAB,FIELD_TAB,RETURN_TAB.

REFRESH:VALUE_TAB,FIELD_TAB,RETURN_TAB.

FIELD_TAB-FIELDNAME = 'BSART'.

FIELD_TAB-TABNAME = 'EKKO'.

APPEND FIELD_TAB.

LOOP AT I_TYP.

VALUE_TAB-BSART = I_TYP-BSART.

APPEND VALUE_TAB.

ENDLOOP.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

RETFIELD = FIELD_TAB-FIELDNAME

TABLES

VALUE_TAB = VALUE_TAB

FIELD_TAB = FIELD_TAB

RETURN_TAB = RETURN_TAB

EXCEPTIONS

PARAMETER_ERROR = 1

NO_VALUES_FOUND = 2

OTHERS = 3.

Hello Balaja,

you can fill fields in Selection-Screen depending on a just entered value in AT SELECTION-SCREEN OUTPUT event. Usually the user has to press enter to get into this event.


AT SELECTION-SCREEN OUTPUT.
	SELECT SINGLE 	something
		FROM    somewhere_source
		INTO	pa_field2
		WHERE	WHATEVER = pa_field1.

AT SELECTION-SCREEN OUTPUT will not be performed when using F4. To automatically fill also the dependend fields when using F4 I prefer to build up a DDIC structure containing the fields I want to display on the selection-screen. Within the DDIC structure I can assign Search helps to the fields. This works well for search helps with more than one exporting parameter.
