Validation check in selection screen

Former Member — Tue, 02 Feb 2010 13:18:22 GMT

Hi experts,

I have 2 parameters p_a and p_b in my selection screen.

What I need is that the users enters value in at least one of these parameters.

If not, he should get a proper error message to do so.

How and in which event should i do this?

Thanks,

Ajay.

In the INITIALIZATION event.

Write the following logic.

IF p_a is intial OR p_b is intial.

Message e(XXX).

Endif.

Hi,

You can check this with simple if else condition.

If p_a is initial and p_b is initial.
* Give error message saying at least one of the fields needs to be filled.
Endif.

Thanks,

In the event 'At Selection-screen' , use the code

if p_a is initial and p_b is initial.

Message e001(ZXX).

endif.
