Hi @LeeJaeYoung, if this wall already exist in the lower floor and extending to this Roof Floor as I see from screenshot then you are right to use All Relevant Stories for Show on Stories and you can use Overhead All for Floor Plan Display.

There may be a translation issue here. I think what you are asking is... Because columns and beams can be shown as hidden line below a slab (using MVO settings) then why is this not possible with walls?
I think columns & beams were given special treatment for their importance in the building structure. Walls have never been granted this option. You could request it is added to the wishes.
One work around, which isn't ideal, is you create a new View of the floor below with all lines set to "Hidden". This can then be added to the Layout sheet with the upper floor plan. You may have to play with display orders and slab fills to get it to show properly.
Failing that you may have to resort to 2D line annotation using the Trace View.

Archicad doesn't support it. But I think using GOC(GOR) is better. The problem is that you have to create and set each GOC (GOR) for each floor. Are there any downsides? I appreciate your teaching of knowing that your method has the advantage of being able to represent many parts of the downstairs. ^^
Here, I would like to know how to solve the disadvantage of having to create each GOC (GOR) for each layer because there is no conditional statement that says if it is not the current story. I would like to know how to solve it with one RULE. ^^
I know that your words are correct. Rather than making a GOC that turns off the overall line of the lower floor from the upper floor of the building floor, I found that the method you gave me is the correct answer. thank you ^^
