Session is a wrapper (or more appropriately an instantiation) of your mapping which can be executed. Workflow is a collection of tasks (one of these is the session) which represents the dependencies and execution logic/order.
Hi Rao, Find my views below: 1.diff between session parameters and workflow parameters: We can define parameters at mapping level only and then mention the parameter file at session level..at workflow level we dont have the term parameters we have only workflow variables which act as both parameters and variables.
A mapping parameter is a constant value that you can define before running a session. A mapping parameter retains the same value throughout the entire session. You can find many examples regarding variables and parameters in the Informatica Marketplace Website. You may find the following examples helpful to understand them in depth.
Mapping task level define advanced session properties; You can pass the param file name from Taskflow: You can define different parameter files and pass them from Taskflow1 (param1) Taskflow2(param2) to specify the session log file name. This allows for greater flexibility in managing session log file names through parameterization.

We are finding an issue with session log parameter values. When with define the variable /value within Global or WorkFlow header, it shows up in session log.
Hi Gurus, I hit a block when using two different parameter files in workflow and session level. I have parameter file para1 in workflow level, inside the workflow, I have para2 for one specified session (session1). but when runing workflow, the session1 only read para1, it doesn't use para2. My question is: does informatica ignor the session level parameter if there is a parameter file defined ...
Again. once your session complete, only then you can see the "updated" value. The alternatives are:- 1. You can update this value in a table and read it in your pre-sql.
