Error insert data over db link in table covered by materialized view

Question

Hello together,
following problem:
I got a table called LOCATION_INFO which is defined:
create table LOCATION_INFO
LOCATION_ID VARCHAR2(40) not null,
PLANT VARCHAR2(4) not null,
PRODUCT VARCHAR2(3),
AREA VARCHAR2(1),
LINE NUMBER(10),
STATION NUMBER(10),
STATINDEX NUMBER(10),
FU NUMBER(10),
WP NUMBER(10),
TP NUMBER(10),
LOCATION_LEVEL NUMBER(1) not null,
LOCATION_PARENT_ID VARCHAR2(40),
TIME_STAMP TIMESTAMP(6) WITH TIME ZONE not null
I try to load data over PL/SQL procedure from another database using database link:
INSERT INTO LOCATION_INFO
(LOCATION_ID,
PLANT,
PRODUCT,
AREA,
LINE,
STATION,
STATINDEX,
FU,
WP,
TP,
LOCATION_LEVEL,
LOCATION_PARENT_ID,
TIME_STAMP)
SELECT LOCATION_ID,
PLANT,
PRODUCT,
AREA,
LINE,
STATION,
STATINDEX,
FU,
WP,
TP,
LOCATION_LEVEL,
LOCATION_PARENT_ID,
GetUTCDateTime(TIME_STAMP) AS time_Stamp
FROM LOCATION_INFO@SOURCE_MMPDDB
WHERE ROWNUM < 100;
This works fine (If i do select count(*) from location_info the data is present) but if set a commit
ORA-00603 appears and the session is terminated.
The point is i got a materialized view MVIEW_LOCATIONS in another schema in the database reading the data from my table location_info and a corresponding MVIEWLOG.
create table MLOG$_LOCATION_INFO
LOCATION_ID VARCHAR2(40),
SNAPTIME$$ DATE,
DMLTYPE$$ VARCHAR2(1),
OLD_NEW$$ VARCHAR2(1),
CHANGE_VECTOR$$ RAW(255)
CREATE MATERIALIZED VIEW MVIEW_LOCATIONS
REFRESH FAST ON COMMIT
ENABLE QUERY REWRITE
AS
SELECT "LOCATION_INFO"."LOCATION_ID" "LOCATION_ID","LOCATION_INFO"."PLANT" "PLANT","LOCATION_INFO"."PRODUCT" "PRODUCT","LOCATION_INFO"."AREA" "AREA","LOCATION_INFO"."LINE" "LINE","LOCATION_INFO"."STATION" "STATION","LOCATION_INFO"."STATINDEX" "STATINDEX","LOCATION_INFO"."FU" "FU","LOCATION_INFO"."WP" "WP","LOCATION_INFO"."TP" "TP","LOCATION_INFO"."LOCATION_LEVEL" "LOCATION_LEVEL","LOCATION_INFO"."LOCATION_PARENT_ID" "LOCATION_PARENT_ID","LOCATION_INFO"."TIME_STAMP" "TIME_STAMP" FROM "CP4MMPDNEW"."LOCATION_INFO" "LOCATION_INFO";
What do I need to do to make the insert working properly without deleting my mviews?
Can anyone help me?
Thanks, Matthias

Helllo,
Can you change this on your Materialized View DDL:
REFRESH FAST ON COMMITTo:
REFRESH FAST ON DEMANDThen, if your INSERT and COMMIT works OK then, can you try:
exec DBMS_MVIEW.REFRESH('MVIEW_LOCATIONS')
