Ouput field is not getting displayed

Hi All,

I created an object type in BOB which gives me ernam field of MARA table on testing.

I need to use that object type in the new workflow in which user inserts a material number and should get ernam (Created by) as an output field.

I tied doing that but on testing , it shows task's status 'COMPLETED' but does not display the ERNAM.

What else I need to do to make it displayed on the screen?

Thanks in advance

Shweta
