The workload management open API provides an SQL interface to the PMPC subsystem and Teradata Database system through user-defined functions, embedded services functions, and external stored procedures. Most of the SQL interfaces available to the PMPC subsystem provide similar functionality to the CLIv2 or Teradata JDBC Driver requests.

Most open APIs do not follow transaction rules. If a transaction calls a UDF or external stored procedure and the transaction rolls back, the action of the UDF or external stored procedure is not rolled back. However, the external stored procedures that update the TDWM database must follow the transaction rules. If a transaction calls one of these external stored procedures and the transaction is aborted, the update will be rolled back.
