How do I pass a variable from one session to another in Informatica?

You can do this using mapping and workflow variables.

  1. In mapping1 create a mapping variable say var1 and set its value to join_date.
  2. Create a workflow variable in the workflow, say var_wkf.
  3. In session1, in Post-session on success variable assignment, assign var_wkf = var1.
  4. In mapping2, create a mapping variable, say var2.

Can we use mapping variable in session?

If you use mapping variables in a session, you can clear any of the variable values saved in the repository by editing the session. When you clear the variable values, the Integration Service uses the values in the parameter file the next time you run a session.

What is pre session variable assignment Informatica?

Pre-session variable assignment. You can update mapping parameters, mapping variables, and session parameters before a session runs. You can assign these parameters and variables the values of workflow or worklet variables in the parent workflow or worklet.

What is the difference between mapping parameter and variable in Informatica?

Mapping Variables Unlike a mapping parameter, a mapping variable represents a value that can change through the session. The Integration Service saves the value of a mapping variable to the repository at the end of each successful session run and uses that value the next time you run the session.

How to create session variables with values in parameter file?

Create session variables with values in parameter file using single ‘$’ and assign accordingly into your sessions.

Otherwise the Integration Service will not fetch proper values.
