I need to read a reference inside of a data object

Hi Developers,

I need to read some data that is nested deep inside a method. My situation looks like this:

data object

     IREF_MDO_DATA       Type    Reference

          v

         OREF_MDO_HANDLER   Type    Reference

              v

             STR_DOF_FILTER_VALS   Type   Deep Structure(232)

                  v

               ASSIGNMENT_TYPE

               SALES_AREA

               DOC_NUMBER

               SALESORG

My question is how do i access  OREF_MDO_HANDLER  and then access STR_DOF_FILTER_VALS  ?

Please let me know if you need more information? I will do my best to explain better?

Thanks,

Patrick
