Dears Regarding the load builder: i made a theissen polygon using a shape file as a boundary layer. then, i used a copy of the boundary layer shape file and assign attribute valve to it with the total demand m3/day using ArcMap.
Then in loadbuilder i used the area load method, prop. dist. by area and i used the new ArcMap - edited shape file as a flow boundry layer. and the theissen polygon as service area layer. the loadbuilder then shows an error messege "2 Id(s) do not match any id of the model." please, help me with this problem . Thanks in advance.
