Without a session task, you cannot execute or run a mapping and a session task can execute only a single mapping. The Parameter file will be modifying with latest status value after the completion of every session right. You will find following examples useful. Command task - Similar behavior as the Decision task occurs. You will also find over 400 mapping samples and many other useful tools on the same website. Informatica for AWS; Informatica for Microsoft; Cloud Integration Hub; Complex Event Processing. Additional Comments * Submit. For achieving dynamic value within session run. You cannot post a blank message. Knowledge Link: Working with PowerCenter workflows, sessions, and tasks. The Decision task has a predefined variable called $Decision_task_name.condition that represents the result of the decision condition. Scenario is like this my $$Status  will have different values say 0,1,2 and according to these 0,1,2 values I want to send mail. The Decision task has a predefined variable called $Decision_task_name.condition that represents the result of the decision condition. Please turn JavaScript back on and reload this page. Error: You don't have JavaScript enabled. In session_1 properties-->component--> post_sucess_command Ihave assigned these 3 parameters to 3 workflow level variables. 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 in session_1 I have defined param file path and In mapping I have defined 3 parameters. Actually these parameter should pick up the values from above param.txt file. Create and Validate the Expression, Step 3. first you have to create Variables instead of parameter. Decision Transformation Conditional Statements, Decision Transformation Advanced Properties, Transformations in the Native and Hadoop Environments, Rules and Guidelines for Multi-Group Transformations, Temporarily Store Data and Simplify Complex Expressions, Guidelines for Configuring Variable Ports, ERROR Functions in Output Port Expressions, Reusable Transformation Instances and Inherited Changes, Editor Views for a Reusable Transformation, Editor Views for a Non-Reusable Transformation, Propagated Port Attributes by Transformation, Example: Editing a Transformation in Excel, Rules and Guidelines for Copying from Excel, Cache Size Increase by the Data Integration Service, Step 1. 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. The decision task allows you to specify the condition using which you can control the execution of branches in a workflow. Was this article helpful? HOW TO: Configure a PowerCenter workflow to capture the exit code of a command and use it in a Decision task. I guess I am missing something thats why parameter values are not populting from param.txt. Try to create seperete param file for all the sessions and call that param file in each session. start-->Session_1-->Decision_Task--[$$Status=0]----> Session_status_0. Logic is  case ($$Status, when 0 then session1 for sending mail. can you pl tell me what will the reason for this? and assign those variables to session post variable assignment. Decision task - When a variable within session 2 generated paramter file is called upon in this decision task, it either does not recognize the variable or it uses the one in a workflow parameter file, if a variable of the same name is defined in the workflow parameter file. Using decision task, condition can be validated and then the operation can be performed. Follow Following. When I used to debug the mapping my parameter values are not correct means they are blank or 0.
