Transaction Routing › Directory Services User Exit › Transaction Code

Transaction Code

A transaction code is a character string assigned to a procedure step and associated with a cooperative flow request. In the supplied Directory Services user exit sample, the transaction code is used to perform a lookup in the file IEFDIR.TRN, which maps transaction codes to cooperative flows and server names. The user exit performs the lookup and returns the name of the target server to be used to process the cooperative flow represented by the transaction code.
