I need help with SPT to db2 database file.

Suppose I need the status of a part number 851251-403.

Alpha codes(suffixes) are used to specifiy color. Business logic says that the part in a series with the latest datetime stamp, no matter the color, drives the part number status.

In my status database I have two records 851251-403 and 851251-403A these have a datetime stamp field and the 851251-403A has the latest datetime stamp.

What would be the SPT syntax to find the 851251-403A record while passing the 851251-403 within my where clause?
