unable to find shortest distance

unable to find shortest distance for al nodes in the following workflow. Does i need to specify the source and target each time for each node in the worklow? the network graph in the end is not showing any graph am i wrong somewhere?

Does anyone have solution for the same?

Hi Jassk,

that Shortest Path node computes the shortest path between the specified nodes in the given network. The nodes (ids) have to be specified in the node dialog. To extract the shortest paths for more than one pair of node you need to loop over these pairs and control the dialog settings as flow variables.
