How to get values from workflow to program

Hello everybody,

I am stuck with an issue in workflow. I want to know how can I get the values of workflow in Abap program.

Scenario:

The workflow is triggered when a user does the transaction MIGO.

The user gets a workflow in his SAP inbox. He clicks on the link and is able to view details in MIGO.

I want to get the material number and year in program ( as shown below)

I am new to workflow, is there any kind of binding to do? And maybe a method or function module which will allow to get these values in program.

Thanks a lot

Regards
