The Input and Output Data Sets

The Input Data Set

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.

The Output Data Set

If the output data set exists, new output data overwrites any existing data. The type of the output data is determined by the service.
