Hi @TaTSouraD,

You can write either an expression in the XML message of your XML BR or get the datetime from a standard SQL view associated with custom metadata.

Scenario 01 - Using Expression in XML Message

Using an Expression in the XML Message. Here you need to add perfom_evaluate_expression perform message in the xml message within perform_batch message. In the expression you can mention any table since you generally need to get the current time (in my case I have used request table since I’m doing some modification to request screen). Then pass the key items (the primary key(s) ) as the parameters. Finally put the function now() to get get current combined date and time in the expression tag as below.

Then you need to pass that value from the xpath for the relevant field that you’re trying to update. The field should be a datetime field in this case.

<perform_batch>
    <sequential_dependent>
        <perform_evaluate_expression>
            <parameters>
                <table_name>request</table_name>
                <keys>
                    <key_item>
                        <column_name>request_id</column_name>
                        <column_value>@request_id</column_value>
                    </key_item>
                </keys>
                <expression>NOW()</expression>
            </parameters>
        </perform_evaluate_expression>  
    <update_time_commit>
        <time_commit>
            <tc_id>@tc_id</tc_id>
            <actual_dttm xpath_node="//perform_evaluate_expression_result/response"/>
            <update />
        </time_commit>
    </update_time_commit>
</sequential_dependent>
</perform_batch> 

Scenario 02 - Using Custom SQL View

You can create a custom sql view with any valid sql function like GETDATE() and then define that view as readonly in custom metadata. Finally you can pass the date from that view to relevant field through the xpath after a tabular or hierarchy select with in a perform_batch message.

Hi @Saranga Amaraweera,

Thank you. It solves my purpose.

Hi @TaTSouraD ,

In addition, an expression can also be used using the @expressiono] substitution. 

for example:

<update_request_event>
  <request_event>
    <request_id>@request_id</request_id>
    <sequence />
    <event_type>MANUAL</event_type>
    <user_def_dttm1>@expression"Now()]</user_def_dttm1>
    <insert_update is_initialized="False" />
  </request_event>
</update_request_event>
