Need example of Performance Document Extract

Content

Dear all,

I need to build a Performance Document Extract, does anyone have the example of Extract Definition?

What I tried - I used "HRA_EXT_EVALUATIONS_UE" as the root Data Group, and used HRA_EVAL_SECTIONS_RATINGS_UE, but I cannot find out which DBI Group returns the "Numeric Rating" or "Rating level", for example, how to get the "Numeric Rating" or "Rating Level" of a Worker's "Overall Summary" section? 

I was blocked here. An example will be very helpful. Thank you very much!
