RE: Assignment task in informatica
The Assignment task allows you to assign a value to a user-defined workflow variable. To use an Assignment task in the workflow, first create and add the Assignment task to the workflow. Then configure the Assignment task to assign values or expressions to user-defined variables. After you assign a value to a variable using the Assignment task, the PowerCenter Server uses the assigned value for the variable during the remainder of the workflow.
