执行了insert语句，用的是测试账号,对这个测试账号创建了同义词

--FOR OBJECT OWNER SCHEMA   'KDUSER1'
CREATE PROFILE "PF_EAIINTF" LIMIT

GRANT CREATE SYNONYM TO RL_EAI_INTF;

GRANT "RL_CONNECT" TO "TAEAIKDMS";
GRANT "RL_EAI_INTF" TO "TAEAIKDMS";
--GRANT TABLE
GRANT SELECT , INSERT, UPDATE, DELETE ON KD_INTERFACE_PR 
TO RL_EAI_INTF;
--GRANT SEQ
GRANT SELECT ON seq_kdPRInterface TO RL_EAI_INTF;
--SYNONYM for table and seq
CREATE OR REPLACE SYNONYM TAEAIKDMS.seq_kdPRInterface FOR 
HANFEI.seq_kdPRInterface;
CREATE OR REPLACE SYNONYM TAEAIKDMS.KD_INTERFACE_PR FOR
 HANFEI.KD_INTERFACE_PR; 

  完毕之后用TAEAIKDMS账号登录执行insert语句发现提示：同义词转换不再有效

查看语句发现是系统付权限账号不对,应该用kduser01才对,将hanfei账号执行的语句改为kduser01即可
