Create Table Security

I need some help in the way security works with the "Create Table " 
command.

I have a library "OTPTEST1" and a user profile "OTPTEST1".  The user 
profile "OTPTEST1" has primary group "AMPGMR" and my user profile's 
primary group is "AMPGMR". 

OTPTEST1

Group profile  . . . . . . . . . . . . . . :   AMPGMR 
Owner  . . . . . . . . . . . . . . . . . . :   *USRPRF
Group authority  . . . . . . . . . . . . . :   *ALL 
Group authority type . . . . . . . . . . . :   *PGP 

When I try a RUNSQLSTM on a script that creates a table with a primary key 
and label statements, it fails with the following.

Ownership of object CHAINTEST in OTPTEST1 type *FILE changed.
Not authorized to perform operation on file CHAINTEST. 
Function not done for user profile AMPGMR. 
One or more errors occurred during processing of command. 
Constraint was removed. 
1 constraint(s) removed from file CHAINTEST. 
Not authorized to object OTPTEST1 in *N type *USRPRF. 
RUNSQLSTM command failed. 

I should have the authority...what am I missing?
