The NETFLOW Procedure |
The SAS variable in this list, which must be present
in the NODEDATA= data set, contains supply and demand
information for the nodes in the NODE list.
A positive SUPDEM list variable value
denotes that the node named in the NODE list variable
can supply
units of flow.
A negative SUPDEM list variable value
means that this node demands
units of flow.
If a SAS variable is not explicitly specified,
a SAS variable with the name _SUPDEM_ or _SD_ in the NODEDATA= data set
is used as the SUPDEM variable.
If a node is a transshipment
node (neither a supply nor a demand node),
an observation associated with this node need not be present in
the NODEDATA= data set. If present, the SUPDEM list
variable value must be zero or a missing value.
