You can edit extraction maps to make minor changes to them, for example:

When you use extraction maps, you do not need to add the DTL__CAPXACTION field nor do you need to include an Update Strategy transformation. PWXPC will automatically include the DTL__CAPXACTION column in its SELECT statement for CDC sources. It then uses the value of the DTL__CAPXACTION to construct the appropriate SQL statement (INSERT, UPDATE, or DELETE).
