The DMSRVDATASVC procedure acquires the names of the
columns that the service expects to receive as input from the DataFlux
Data Management service. In this case, the name of the input data
set must match the name that is specified in the service. If the expected
column names do not match the column names in the input data set,
then the DMSRVDATASVC procedure terminates.
Services can also be
created where any named data set can be used for input. In this case,
there is no input data set name required.
