Hi Ruben,
From what I understand in regards to your description,
If you are looking for a query on extracting specific closure date, you can make use of below query as a sample and extract the required fields in your query
pdm_extract -f "select ref_num, close_date from Call_Req"
The above query will list all the records with reference no's and closed date.
Provide me additional information to point you to the correct query, i.e. what do you mean by Auto Close date? Which object are you referring in this case as I don't find a auto close date in CR object?
