Validations on selection screen fields

Bharath84 — Thu, 21 Nov 2013 14:43:30 GMT

Hi All.

Below is my selection screen

p_bukrs like bkpf-bukrs.

p_gjahr like bkpf-gjahr.

p_monat like bkpf-monat,

s_blart for bkpf-blart.

s_mwskz for t007a-mwskz.

How to validate if the Tax Code entered on the selection screen for company code 2500 is INPUT tax code(where T007A-MWART = 'V').

Also Tax code should be populated only for company code 2500 where country is France ( T001-BUKRS = “FR” ) . Show error message if Tax codes are populated for a Company code where country is NOT FR- France.

How to do this and in which event I have to write these conditions. Please help me.

Thanks,

Haritha

Hi,

Use the event AT SELECTION SCREEN to validate the fields.

In the table T001 check for the field LAND1 is FR or not using BURKS, if not show error message.

HI haritha,

you can write the code as,

AT SELECTION SCREEN.

if s_mwskz EQ 'V' AND taxcode EQ 2500.

if BUKRS NE 'FR'.

message 'Write your error message here' type E.

endif.

PARAMETERS : p_mwskz TYPE t007a-mwskz,
              p_bukrs TYPE bkpf-bukrs.

if p_bukrs ne 'FR'.
MESSAGE : 'Enter Correct Code' TYPE 'E'.
endif.

   IF p_mwskz NE '2500'.
     MESSAGE : 'Enter Correct Code' TYPE 'E'.
   ELSE.
     SELECT SINGLE * FROM t007a
        INTO wa_t007a
       WHERE mwskz = p_mwskz
       AND mwart = 'V'.

Hii Haritha,

To validate the selection screen elememts , use EVENT AT SELECTION-SCREEN [ON BLOCK, ON SCREEN, ON FIELD].

Here is sample validation code .

REPORT zr05_validation.

DATA v_mwart TYPE mwart.

PARAMETERS p_bukrs TYPE bukrs. "Company code

SELECT-OPTIONS s_mwart FOR v_mwart. "Tax type

AT SELECTION-SCREEN.

IF p_bukrs IS INITIAL .

SET CURSOR FIELD 'P_BUKRS'.

MESSAGE 'Enter the Company Code ' TYPE 'E'.

ENDIF.

IF s_mwart IS INITIAL.

SET CURSOR FIELD 'S_MWART'.

MESSAGE 'Enter the Tax type' TYPE 'E'.

ENDIF.

IF NOT p_bukrs IS INITIAL AND

NOT s_mwart IS INITIAL.

IF p_bukrs EQ 2500 AND

s_mwart-low NE 'V'.

SET CURSOR FIELD 'S_MWART'.

MESSAGE 'Enter the tax type as V ' TYPE 'E'.

ELSEIF p_bukrs EQ 2500 AND

s_mwart-low EQ 'V'.

SELECT SINGLE COUNT(*) "Validating the company code for country as FRANCE

FROM t001

WHERE bukrs EQ p_bukrs

AND land1 EQ 'FR'. "FR as FRANCE

Write all the validation under the event AT SELECTION SCREEN so that if any error is there it will stay in the same page and display error.

AT SELECTION SCREEN.

SELECT SINGLE COUNT(*) "Validating the company code for country as FRANCE

FROM t001

WHERE bukrs EQ p_bukrs

AND land1 EQ 'FR'. "FR as FRANCE

if sy-subrc <> 0

message e000 with text-001. (double click on text-001 and print appropritate text)

Hi Haritha,

The following are the proessing blocks in ABAP:

NITIALIZATION

Before the standard selection screen is displayed

AT SELECTION SCREEN OUTPUT

This is called just before the selection screen is displayed and can be used to manipulate the actual selection screen attributes using teh loop at screen functionality. This allows you to do things like hide fields, grey them out so they are output only or make them intensified etc.

AT SELECTION-SCREEN

After user input on a selection screen has been processed, but while the selection screen is still active

START-OF-SELECTION

After the standard selection screen has been processed, before data is read from the logical database

END-OF-SELECTION

After all data has been read by the logical database

List processor events:

TOP-OF-PAGE

In list processing when a new page starts

END-OF-PAGE

In list processing when a page ends

AT LINE-SELECTION

When the user triggers the predefined function code PICK

AT PFnn

When the user triggers the predefined function code PFnn

AT USER-COMMAND

When the user triggers a function code defined in the program.

So in order to validate you should use at selection screen.
