Error while importing a dump

Question

hi gems..
i have a expdp dump of a schema and then tried to import that dump using the impdp command.
the import worked but two tables got failed. those two tables have partitions and subpartitions.
i use the command
impdp touser/password@sid directory=dmpdir dumpfile=dumpfile.dmp logfile=logfile.log remap_schema=(fromuser:touser) PARTITION_OPTIONS=MERGE
the error code is:
ORA-39083: Object type CONSTRAINT failed to create with error:
ORA-01741: illegal zero-length identifier
Failing sql is:
ALTER TABLE "TOUSER"."TABLE1" ADD CONSTRAINT "CONSTRAINT_NAME" PRIMARY KEY ("COL1", "COL2", "COL3", "COL4", "COL5") USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 STORAGE( BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT) LOCAL (PARTITION "P1" TABLESPACE "" ( SUBPARTITION "SYS_SUBP21" TABLES

ORA-39083: Object type CONSTRAINT failed to create with error:
ORA-01741: illegal zero-length identifier
Failing sql is:
ALTER TABLE "TOUSER"."TABLE1" ADD CONSTRAINT "CONSTRAINT_NAME" PRIMARY KEY ("COL1", "COL2", "COL3", "COL4", "COL5") USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 STORAGE( BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT) LOCAL (PARTITION "P1" TABLESPACE "" ( SUBPARTITION "SYS_SUBP21" TABLES
Error:  ORA 1741
Text:   illegal zero-length identifier
Cause:  An attempt was made to use two double quotes ("") as an identifier.
        An identifier must be at least one character long.
Action: Insert at least one character between the double quotes in the
        identifier.
        If a blank identifier is required, specify a blank space between the
        double quotes (" ").If you see the above statement, there is blank value,
LOCAL (PARTITION "P1" TABLESPACE ""
TABLESPACE "" remove this (or) put a valid name and reexecute manually.
