Doubt on instantiation of method

Hi All,

I am supposed to debug a method of wf.On execution i found that import parameters of method are referred to class.
As a result i get following screen shot on execution:

Following screen appears on clicking above highlighted symbols for IO_PURCHASEORDER.

When i clicked on above circled symbols, I am supposed to enter all values from wf technical log as below:

.But the fields from workflow technical log and se24 on execution of method and clicking on Import parameter IO_PURCHASEORDER  are not matching. can any body kindly guide how to debug in these sort of scenarios?

Thanks,

SD
