I need to carry out an analysis that when selecting the water network and everything that is connected: - fill in the fields created in the network with customer quantity values and the valve IDs in another field. To select everything that is contained in the network I will use Trace. For the automatic provisioning of this information I am trying on the fields created in the water network I will use the Attribute-Assistant, but I can not concatenate the ID of two different valves on the same line as for example. (1,2) I tried to add the values of other layers to play in the network field but I did not find a solution. Does anyone have any ideas?
