export of a schema -

changes made by application to the db gets committed
WHEN THE DATa is committed that time parent table has already been exported and child table ais getting exported

whole export is over giving message
export terminated successfully without warnings.

now while importing it gives
IMP-00017: following statement failed with ORACLE error 2298:
"ALTER TABLE "PRONTO_CUSTOMER_SESSION" ENABLE CONSTRAINT "FK_PRONTO_C_REF_89"
"10_PRONTO_C""
IMP-00003: ORACLE error 2298 encountered
ORA-02298: cannot validate (PRONTOMSP.FK_PRONTO_C_REF_8910_PRONTO_C) - parent keys not found

what needs to be done in the db where it is imported.

thanks in advance
