I have a incoming deep structure in my recursive method which contains structures and tables, so I'm working with RTTI to check type, loop over it and do my operation, in case I found a specific component.

If the current component is a structure or table, then method calls itself.

Problem: I import the structure with type any. So far so good. And i want to export it as type any also.

And here I struggle.

How can I assign my edited deep structure to my export parameter ?
