Selection-screen value check

[Former Member]

Hi, there is a selection-screen. How can I check on the selection-screem that the asset transaction type which I typed in is whether existing to a given asset? I would like to display an informational message on the status bar about it if doesn't exist.

HI,

Try this:

AT SELECTION_SCREEN.

Select single asset into variable from dbtab where asset EQ selection-value.

If sy-subrc eq 0.

do processing.

else.

Message.

endif.

Reward if this helps.

Hi,

AT SELECTION_SCREEN.

Select single asset into v_assest from dbtab where asset = s_asset value.

If sy-subrc <> 0.

Message e001 ' enter valid asset number'.

endif.

Hi,

After your selection screen, use..

AT SELECTION-SCREEN ON fieldname.

Write relevent select statements under this to check if the entries exist,

display message where applicable.

at selection-screen.

check by writing a select statement to check whether it exists or not.

if exists....

do further processing

else.

come out...

endif.
