I have a question on this query. It is my understanding that the bolded and underlined section starting with "qualify row_number" would group all the records by pst_obligor_id, pst_fac_id, pst_sys_id and Maturity_date and pick only one record based on the most recent period (If priod date is the same, move to book, then ecposure, etc.). Is this correct?
If it is correct, then how do I have 2 records with different COLLATERAL_CD fields? (Please refer to my jpg of data output)
Thank you very much.
Double check if the combination of (pst_obligor_id,pst_fac_id,pst_sys_id,Maturity_date
