Pass date value from one session to another session in the same workflow

问题

I have two sessions i a workflow like below

workflow1->session1->session2

i have a join_date column in a table in Mapping1 , in session1

i want to pick this join_date value and pass to mpping2/session2

If join date value changes in the table in session1 then the same value should pick and pass to session2

I will use this date value in a query in session2 .

Please tell me how to achieve this?

Thank you

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
5. In session2, in Pre-session variable assignment, assign var2=var_wkf
6. You can use the var2 variable in mapping2, it should have the value set in mapping1
