Document Template Designer: IF and MERGEFIELD = IMPOSSIBLE?

Hey Gang

I have a problem with with a document templatge designer.

When I want to include some logic in the template e.g. IF with a MERGEFIELD it is not possible to do so.

1. { MERGEFIELD BUAG_BUKRS } -> Working

2. { IF { MERGEFIELD BUAG_BUKRS } = "6" "Right" "Wrong" } -> Not working

This should be possible somehow? Or do I have to solve this in the BADI?

I read in some threads but no one has a solution for this.

Can anyone help me out here?

Cheers.
