How do i create a structured header in ALV or any other grid layout in SAP ABAP?

Question

So to illustrate:

|         Category A            |         Category B            |  C  |
|     A.A       |      A.B      |      A.A      |      A.B      |     |
| A.A.A | A.A.B | A.B.A | A.B.B | B.A.A | B.A.B | B.B.A | B.B.B |     |

I need a header that looks somewhat like this and I was wondering if there's a way to do it other than manually WRITE each line. :D

Depending on the scenario, you might be able to bend the XXL API to generate the list in Excel. Try executing the demo program XXLFTEST and have it export the results to a pivot table - maybe you could use this? Other than that, I know of no control that is able to do this. You could WRITE the stuff yourself, of course, or you could try to persuade the users to have the hierarchy on the vertical axis and use a standard column tree...
