Problem when extracting the structure of DB2 (Back up Structure)

I want to extract the structure of a 9.7 DB2 database to use to clone it but some of the authorization statements are missing afterwards: I tried something like this: db2look -d dbName -a -x -o db2look.sql what I noticed, is that the *Authorization Statements on User Defined Functions* and *Stored Procedures* are missing. I expected to see something like this: https://www-01.ibm.com/support/docview.wss?uid=swg1IC65658 EDIT: A try indicated, that this command correctly extracted the GRANTstatements on the productive system.
