Hello Günter,
my fault. The module name has been changed from sapdb to sdb.
Change in the script the strings sapdb.dbm to sdb.dbm. It occures twice.
If you like to know from where python loads the modules you can use
x_python
>>> import sdb.dbm
>>> sdb.dbm
<module 'sdb.dbm' from 'D:\sapdb\clients\D73\lib\python2.3\sdb\dbm.pyd'
Kind regards,
Burkhard
