Hi Yves
Thanks for the reply.
I did activated the table DDXTT and DDXTF.
Its activated with warnings n yellow such as
======================
Enhancement category for table missing
Enhancement category for include or subtype missing
POSITION already active and reserved (If possible, select another name
OFFSET already active and reserved (If possible, select another name)
If activation was successful, adjust C structures (where necessary)
Table DDXTF was checked with warnings
