ak_upadhyay — Wed, 26 Mar 2008 03:13:27 GMT

Hi,

I am working on screens. there a some input fields

in which user can enter only YES, NO or N/A value,

now my requirement is that if user enters any other

value except YES, NO or N/A than system should throw

the message 'Please Enter Only YES, NO or N/A'.

It's urgent.

Thanks

You have to Validate the screen by using this code in At selection screen on field <fieldname>.

The code is

if <fieldname> ne 'YES' or <fieldname> ne 'NO' or <fieldname> ne 'N/A'.

message 'Please Enter Only YES, NO or N/A' type E.

endif.

Hi AK,

There are few ways you can achieve this ...

1. If you have a data element assigned to the field .. then you can have a value table / fixed value for that data element associated to the field ...

2. If it is a selection screen .. you can put the following condition in "At SELECTION-SCREEN output " event

" if value = 'yes' or value = 'no' or value = 'N/A'

else .

message 'Error'.

endif. "

3. If it is a screen .. then you can have your conidition in PBO Module ... between Chain and Endchain statments ....

Hope this helps a bit ..

Reward if useful.

Cheers

Try as below:


CONSTANTS: c_yes TYPE char3 VALUE 'YES',   " Global Declaration
           c_no  TYPE char3 VALUE 'NO',
           c_na  TYPE char3 VALUE 'N/A'.

" PAI Event

MODULE pai.

  PERFORM validate.


FORM validate.

   IF NOT p_text EQ c_yes OR   " Considering P_TEXT is screen field
      NOT p_text EQ c_no  OR
      NOT p_text EQ n_na.
      MESSAGE e001(00) WITH 'Please Enter Only YES, NO or N/A'.
   ENDIF.
ENDFORM.  " Validate

Above example is w.r.t screen, should you be using in a report program check below example as well:

parameters: p_text type char3 obligatory.

CONSTANTS: c_yes TYPE char3 VALUE 'YES',
           c_no  TYPE char3 VALUE 'NO',
           c_na  TYPE char3 VALUE 'N/A'.

at selection-screen.

   IF NOT p_text EQ c_yes AND
      NOT p_text EQ c_no  AND
      NOT p_text EQ c_na.
      MESSAGE e001(00) WITH 'Please Enter Only YES, NO or N/A'.
   ENDIF.

Hi Kripa, Just to correct you. This can be done in the PAI, but not in the PBO.

And more over you can not use Chain Endchain in the PBO module.

Hi AK, As said by others u can just validate the field using IF statement. You can do it in module PAI between chain endchain giving the screen field name(s) you wnted.

CHAIN.
    FIELD : SCREEN_FIELDNAME.
    MODULE validate_input. " in this moduel u can write the IF statement
ENDCHAIN.

Gopi

Hi use the code,

tables : mara.

Ranges : text for mara-ZEIAR.

Initialization.

text-sign = 'I'.

text-option = 'EQ'.

text-low = 'YES'.

append text. clear text.

text-sign = 'I'.

text-option = 'EQ'.

text-low = 'NO'.

append text. clear text.

text-sign = 'I'.

text-option = 'EQ'.

text-low = 'N/A'.

append text. clear text.

if field1 not in text.

message 'Please Enter Only YES, NO or N/A' type 'S'.

endif.

if field2 not in text.

message 'Please Enter Only YES, NO or N/A' type 'S'.

endif.

if field3 not in text.

message 'Please Enter Only YES, NO or N/A' type 'S'.

endif.
