in which 106151 and 106153 could be any legal entity primary key of product and ProductContent. They are defined by source id in definition of API.
But for a url path for a screen path, how could we do the similar? I know there is a mechanism called extra path parameters. Those parameters can only be handled in one screen file. Is it possible that we could have a screen def file for product, then in this screen def file, we handle product with primary 106151, then we go to sub screen def file for content, then handle content with primary key 106153?
You are right about this. I just do not like the parameter ways and try to make it using url path. And I also thought that the tree path would be more logic in some scence. Anyway, I did it in the sample way as you suggested.
