Datapump: cloning schema, target has multiple size. How to solve?

Question

Hi all,
I am quite unfamiliar with dataump - i've used imp / exp before.
Now I need to clone a schema and have to remap the tablespaces. The forum advised me to use datapump but now I have some problems with it:
source schema name: DEV_6
target schema name: TESTUSER
I checked the size of the schemas with the following statement:
select owner, sum(bytes)/1024/1024 tsize
from dba_segments
group by owner
order by tsize desc;
My source (DEV_6) has the size of 4GB.
After importing the target (TESTUSER) has a size of more than 32GB (import is still running)
I exported the schema with following statement:
expdp DIRECTORY=DATA_PUMP_DIR DUMPFILE=DEV_6.expdp LOGFILE=DEV_6_exp.log SCHEMAS=DEV_6
For importing and remapping schema and tablespace I used the following statement:
impdp LOGFILE=TESTUSER_imp.log REMAP_TABLESPACE='AMES_DEV_PERM':'TESTUSER_PERM','DEV_TRUNK_DATA_XXL':'TESTUSER_PERM' REMAP_SCHEMA='DEV_6':'TESTUSER' SCHEMAS='DEV_6' DIRECTORY=DATA_PUMP_DIR DUMPFILE=DEV_6.expdp
We are using 11.2.0.1.
Any ideas how to solve this problem?
Thanks in advance,
Andreas

Hi,
I think I found the problem:
The definition of the tablespaces differs:
TABLESPACE_NAME BLOCK_SIZE INITIAL_EXTENT NEXT_EXTENT MIN_EXTENTS MAX_SIZE ALLOCATION_TYPE
TABLESPACE_ORG 8192 65536 null 1 null SYSTEM
TABLESPACE_NEW 8192 131072000 131072000 1 2147483645 SYSTEM
