simple question

[Former Member]

hi!

I have an abap program where I should build a check on the following

parameters: p_date type dats.

How can I check if p_date is at least one year ago compared to today? If not, an error message should be printed to screen, and the rest of the program should not be executed.

also, if possible, default value for the p_data parameter should be the date one year ago compared to today

simple question from a beginning abap programmer

thanks !

Hello Joris,

parameters: p_date type dats.

at selection-screen on p_date.

data: l_date type dats.

l_date = sy-datum.

l_date0(4) = sy-datum0(4) - 1.

if p_date > l_date.

message e308(00) with 'Enter date one year ago'.

endif.

Hi,

DATA : v_i type i.

v_i = sy-datum - p_date.

IF v_i LE 365.

MESSAGE to show "p_date is at least one year ago compared to today"

ENDIF.

HI,

check this logic.

<b>

parameters: p_date type dats.
data: a type datum.

a = sy-datum.
a(4) = sy-datum(4) - 1.

if p_date(4) > a.
    MESSAGE E000(su) WITH 'date is not valid'.
endif.
write:/ a.

</b>

Hi Joris,

U can validate any selection screen fields in the event

at-selection screen.

1. To validate date,

the internal format for the date storage is : DDMMYYYY.

take a variable say w_year.

w_year = sy-datum+4(4).

The above statement will store the date.

take another variable which contains the previous years date (use offset as of above). Compare and generate am error message.

2. U can default values in the selection screen using the event initialization.

Santosh.
