selection screen

[Former Member]

i have five fields in selection screen including quantity and customer number. for a particular value of the customer number a window pops up asking for region and postal code. if i enter a wrong value an error message gets displayed . everything is working fine with that but if i simply close that window without entering the values to change the customer number to any other value, the quantity field is lost.Its made mandatory before and just the ? displays indicating the user to enter the value .Its not a big problem but how to restore the quantity value in the selection screen this happens only if the quantity is 0.

I have solved the previous problem by giving the code in initialization event. This is a different problem again at the same place.

SELECTION-SCREEN BEGIN OF BLOCK B1 WITH FRAME TITLE TEXT-001.

PARAMETERS : P_KUNNR LIKE KNA1-KUNNR OBLIGATORY, " customer number

P_MATNR LIKE VBAP-MATNR OBLIGATORY, " material number

QUANTITY LIKE BAPIITEMIN-REQ_QTY OBLIGATORY,

" required quantity

P_VKORG LIKE VBAK-VKORG OBLIGATORY, " Sales organization

P_VTWEG LIKE VBAK-VTWEG OBLIGATORY, " distribution channel

P_SPART LIKE VBAK-SPART OBLIGATORY, " division

COUPON(12). " coupon number

SELECTION-SCREEN END OF BLOCK B1.

INITIALIZATION.

• Internal table for taking postal code and region values from pop

• up window

IVALS-TABNAME = 'KNA1'.

IVALS-FIELDNAME = 'PSTLZ'.

APPEND IVALS.

IVALS-TABNAME = 'KNA1'.

IVALS-FIELDNAME = 'REGIO'.

APPEND IVALS.

AT SELECTION-SCREEN.

IF P_KUNNR = 'SELEDIR' OR P_KUNNR = 'EMPLDIR'.

CALL FUNCTION 'POPUP_GET_VALUES'

EXPORTING

• NO_VALUE_CHECK = ' '

POPUP_TITLE = 'Enter Sold-to party''s Postal code and Region'

START_COLUMN = '25'

START_ROW = '10'

• IMPORTING

• RETURNCODE =

TABLES

FIELDS = ivals

• EXCEPTIONS

• ERROR_IN_FIELDS = 1

• OTHERS = 2

.

IF SY-SUBRC <> 0.

• MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

• WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

• Reading the values from the internal table

READ TABLE IVALS WITH KEY FIELDNAME = 'PSTLZ'.

IF NOT IVALS-VALUE IS INITIAL.

• postal code validation

SELECT SINGLE PSTLZ

INTO PSTLZ1

FROM ZZIPS

WHERE PSTLZ = IVALS-VALUE.

IF SY-SUBRC = 0.

PSTLZ = IVALS-VALUE.

ELSE.

MESSAGE E017 WITH 'Enter the valid Postal code'.

ENDIF.

ELSE.

MESSAGE E018 WITH 'Enter the Postal code'.

ENDIF.

READ TABLE IVALS WITH KEY FIELDNAME = 'REGIO'.

IF NOT IVALS-VALUE IS INITIAL.

• Region validation

SELECT SINGLE REGIO

INTO REGIO1

FROM ZZIPS

WHERE REGIO = IVALS-VALUE.

IF SY-SUBRC = 0.

REGIO = IVALS-VALUE.

ELSE.

MESSAGE E019 WITH 'Enter the valid Region'.

ENDIF.

ELSE.

MESSAGE E020 WITH 'Enter the Region'.

ENDIF.

REFRESH IVALS.

ENDIF.

I see the problem now, what you are seeing is just the way that that type of field is handled in the gui, sometimes if you want 0 to show, you need to make the field as a character field, so in order to fix this problem, you need to adjust the typeing of the parameter field.
