Using Object messages 

If you want to see the content of the messages object (see also Object messages), you can first display a simple table containing the messages. Insert the following code to the body of page default.htm :

<%-- if there are messages, we want to display them in a table --%>
<% if page->messages->num_messages( ) > 0. %>
<h2 class="bspH2" style="background-color:red">The following errors occurred</h2>
<table class="bspTbvStd">
<tr class="bspTbvHdrStd">
<th class="bspTbvHdrStd">Index</th>
<th class="bspTbvHdrStd">Condition</th>
<th class="bspTbvHdrStd">Text</th>
<th class="bspTbvHdrStd">Seriousness</th>
</tr>
<%
data: condition type string,
message type string,
severity type i,
ind type i.
ind = page->messages->num_messages( ).
do ind times.
call method page->messages->Get_message
exporting index = sy-index
importing condition = condition
message = message
severity = severity. %>
<tr class="bspTbvCellStd">
<td><%= sy-index %></td>
<td><%= condition %></td>
<td><%= message %></td>
<td><%= severity %></td>
</tr>
<% enddo. %>
</table>
<p>
<% endif. %>

If you then test by using incorrect entries (for example, enter 47 as the time), you can see the error message(s).

Please note the following:

• Access to the messages object is via the attribute of page page->messages
• You use the method num_messages( ) to query the number of messages (that is, the number of entries in the list)
• One way of accessing the error messages is by addressing them via the index
