Well what do you know. Been searching for ages and now I found http://scn.sap.com/thread/706494.
Quote from 'Sachin' :
The issue due to an inconsistency in table DDNTT/DDNTF.
Try and issue the following database commands.
select * from sapr3.DDNTT where TABNAME = ' ';
select * from sapr3.DDNTF where TABNAME = ' ';
The first sql statement results gives 1 row. You can delete the first entry which has TABNAME as empty and then repeat the phase.
This helped me through.
