Error message disble the Fields in Selection Screen

Former Member — Tue, 07 Jul 2009 10:04:58 GMT

Hi,

In my Report i am validating some fields as mandatory.

If the field is initial then one Error message should be display in the screen and user has to modify the selection screen.

But after displaying the errro message my selection screen is input disable except the mandatory field.

I want all the fields should be input enable.

Sample code for Error message,

MESSAGE E018 WITH 'Enter Plant'.

Please provide the code for this.

Hey,

u can use Obligatory addition while defining the screen.

e.g. PARAMETERS : P_WERKS TYPE WERKS_D OBLIGATORY .

System will itself validate the entry.

Hi,

Try using message type 'W' or type 'I' in place of 'E',

because error message disables the input

fields. or,

Take the input fields as obligatory in your

code and dont use any message type with

those fields, the obligatory keyword throws

error message itself and does not disables the input

fields also.

Hope it helps

Hi,

Use information message instead of Error message

parameter: p_plant(20) type c.

if p_plant is initial.

MESSAGE 'Enter Plant' type 'I'.

endif.

Thanks &regards

Hi,

Do as below,

1) Remove the OBLIGATORY option of the field.

2) For mandatory filling do the validation in AT SELECTION-SCREEN ON field for INITIAL

3) Give the message as I type.

Sample code

PARAMETERS : p_matnr TYPE mara-matnr,
             strt_dat ,
             end_dat ,
             emp_id,
             emp_name,
             location,
             usage.

DATA : w_matnr TYPE mara-matnr.

AT SELECTION-SCREEN ON p_matnr.
  IF p_matnr IS INITIAL.                                                    " This makes the field a mandatory
    MESSAGE 'Enter material ' TYPE 'I'.
  ELSE.
    SELECT SINGLE matnr FROM mara INTO w_matnr
          WHERE matnr = p_matnr.
    IF sy-dbcnt = 0.
      MESSAGE 'Not a Valid Material ' TYPE 'I'.

    ENDIF.
  ENDIF.

START-OF-SELECTION.

Performing checks on SELECTION-SCREEN

- if the check uses only one independent field (e.g.: value exist in a table) use a[ AT SELECTION-SCREEN ON <field>|http://help.sap.com/abapdocu/en/ABAPAT_SELECTION-SCREEN_EVENTS.htm#!ABAP_ALTERNATIVE_2@2@], the field will be editable when error is raised

- if the check uses some fields, group them using [SELECTION-SCREEN BEGIN OF BLOCK <block>/END OF BLOCK <block>|http://help.sap.com/abapdocu/en/ABAPSELECTION-SCREEN_BLOCK.htm] and then [AT SELECTION-SCREEN ON BLOCK <block>|http://help.sap.com/abapdocu/en/ABAPAT_SELECTION-SCREEN_EVENTS.htm#!ABAP_ALTERNATIVE_4@4@], each field of the block will be editable when error is raised

So, if you really want that each and every field be editable when an error is raised, declare every parameter and select-options in a big block, and perform the check in a unique AT SELECTION-SCREEN ON BLOCK xxx.

Use Error message, Warning and Information don't break the flow of the report.

Raymond

Leave List-processing.

ENDIF.

If you use the "big block solution", you will have to manage the CURSOR yourself to indicate the user which field is in an error state.
