Dynamic ALV columns in Web Dynpro ABAP
Does anybody know how to build an ALV with dynamic columns in a WD4A?
I know how to make an ALV with a dynamic context node (dynamic DDIC structure), but it isn't the problem. First, I need to validate data entries, and then I will know how many fields I have to show.
I've been reading about interface IF_WD_CONTEXT_NODE_INFO. I think some of its methods can be useful to me. Can you help me to solve that?
