Problems with sending the Job_ID with activity EMAIL from a processflow

Question

Hello everybody,
i have a problem with a simple process flow.
I want to send an EMail that contains in the MESSAGE_BODY the Job_ID from the started workflow. For that reason i wrote a function with a select statement that gives back the number.
Code:
l_owb_id VARCHAR2(20);
BEGIN
select to_char(top_level_execution_audit_id)
into l_owb_id
from ALL_RT_AUDIT_EXECUTIONS
where task_name = 'XYZ'
and created_on like sysdate;
return (l_owb_id);
END;
The function works fine. So i placed it into my workflow. Now i wanted to bind the MESSAGE_BODY from the activity EMAIL with the parameter of the function. But when i click validate it shows following error:
VLD-10042: Parameter MESSAGE_BODY of EMAIL is incorrectly bound. Output of cannot be converted into a constant value.
VLD-10042: Activity MESSAGE_BODY of EMAIL is currently bound to parameter GET_OWB_ID of .Activities must be bound through an intermediate variable
Can anyone help me how to fix that proplem. How can i send the Process ID per activity EMAIL in a Workflow. On the internet i didn't found anything helpful, so any help would be appreiciated.
Kind regards,
Daniel

Answer 1

You need to create Variable and then bind the value from your function to that variable and than use that variable as parameter for email MESSAGE_BODY.
So you will have:
Variable: p_id
Return parameter of your function will be bind to p_id and message_body of your email will be bind to p_id.
