Do you mean the hydrograph and stage for the structure? You can find it in the plot stage hydrograph button and selecting storage area connection as the type. You could also look in the dss file.
Yes I have a SA/2D connection with a culvert and a weir. The plot stage hydrograph is empty i don’t know why… There isn’t a table like for 1D to know the hydraulic caracteristic in the culvert and in the weir?
