Maxim 34: Work in Steps.

This also means that you must start by checking the log to determine which of the steps take so long, and then optimize those.

What immediately jumps to my attention is this:

   SELECT DISTINCT t1.DATA_DATE, 
          t1.COUNTERPARTY_ID, 
          t1.CREDIT_TYPE, 
            1 AS FLAG,
            (SUM(t2.VALAMOUNT)) FORMAT=22.6 AS SUM_of_EAD
/* ... */
      GROUP BY t1.DATA_DATE,
               t1.COUNTERPARTY_ID,
               t1.CREDIT_TYPE;

by definition, the DISTINCT is not needed here, and might force the SQL procedure to do an unnecessary extra sort.

 

You should also be able to do these two quite similar SQL steps in one, and set the FLAG variable in a CASE clause.

WOW, Almost written by PROC SQL .
SQL is not efficient due to Cartesian Product .
Try original tradition SAS Data Step and Hash Table .

If could try SPDE engine.

libname x spde 'c:\temp';
