Yes you are correct. The Decision task has a predefined variable called $Decision_task_name.condition that represents the result of the decision condition. In my workflow I have set param file path with name in session-->Properties, like Parameter_filename :- /app/.././.././param.txt. start-->Session_1-->Decision_Task--[$$Status=0]----> Session_status_0. can you pl tell me what will the reason for this? Now I have mentioned param file at session level then I have assigned post session variable to workflow variable.Now the issue is in my workflow these values are not populating. You will also find over 400 mapping samples and many other useful tools on the same website. Knowledge Link: Working with PowerCenter workflows, sessions, and tasks. View Article. Informatica for AWS; Informatica for Microsoft; Cloud Integration Hub; Complex Event Processing. In other words, you can check the condition of multiple tasks, and based on that, you can decide whether you wish to trigger the next task or not. Now my workflow is working but I am unable to catch the values of $$Status and $$Error_in_SP because of this my wf is seding three mails. For achieving dynamic value within session run. Please enter your message and try again. I am using one parameter file say param.txt. Set the Tracing Level to Verbose Initialization, Step 2.
