Connect the input data ports to the transformation. Verify that the port names, port order, data types, and precisions must match the port configurations of the transformation that created the data store.
The Match transformation uses preset input ports to determine the order in which it processes the records. The transformation uses a sequence identifier to track the records from the input ports to the matched pairs or clusters that it writes as output. The transformation uses a group key to sort the records that it processes.
Connect the preset ports to the following ports on the Expression transformation:
SequenceID. Connect to the SEQID port from the Expression transformation.
GroupKey. Connect to the City port from the from the Expression transformation.
