This SAS code leverages the PROC SORT procedure to perform the following:

1. Input Dataset: It is sorting the dataset named df_new.

2. nodupkey Option: The nodupkey option tells SAS to remove duplicate observations based on the variables listed in the BY statement. If two or more observations have the same values for the variables in the BY list, only the first occurrence is kept in the output dataset.

3. Output Dataset: The sorted and deduplicated dataset is saved to a new dataset named dataframe_sorted.

4. Sorting Variables: The dataset is sorted based on the variables specified in the BY statement:

   • bi_dt
   • Oblgr_Nbr
   • Default_Ind_OblgrAbsorb The sorting is done in ascending order by default unless specified otherwise (e.g., with descending).

Summary:

This code sorts the dataset df_new by the variables bi_dt, Oblgr_Nbr, and Default_Ind_OblgrAbsorb in ascending order and removes any duplicate rows having identical values for these three variables. The resulting dataset is stored in dataframe_sorted.
