OWB 904 doesn't use DB Links in mapping scripts

Question

I'm having trouble deploying mappings because they don't use the generated DB Links in the mapping scripts.
Normally when deploying a mapping I get this warning that certainly is correct since it can't find the source table:
VLD-2771: System privileges may not allow extraction from source ZIPCODE.
Extract from the mapping script:
CURSOR "ZIPCODE_c" IS
SELECT
"ZIPCODE_DWH"."ZIPCODE" "ZIPCODE",
"ZIPCODE_DWH"."CITY" "CITY",
ROWNUM "ROWNUM_ALIAS$$$"
FROM "AXAPTA"."ZIPCODE" "ZIPCODE_DWH" ;
Only when explicitly typing the name of the DB link in the configure options of the mapping will it work. But when I do this I get the following warning:
VLD-1124: Schema and/or Database link physical configuration parameters should not be set for ZIPCODE.
The version of the code that works:
CURSOR "ZIPCODE_c" IS
SELECT
/*+ NO_MERGE */
"ZIPCODE_dwh.business8123"."ZIPCODE" "ZIPCODE",
"ZIPCODE_dwh.business8123"."CITY" "CITY",
ROWNUM "ROWNUM_ALIAS$$$"
FROM "ZIPCODE"@"dwh.business.auc.dk@dwh" "ZIPCODE_dwh.business8123" ;
Shouldn't the mapping script use the DB Link normally or is there an option I have missed? I see in the Reviewers Guide that the target user is granted access to the source (through Public) but won't this only work if both source and target is in the same database?

Hi guys,
I am facing a strange problem. The code generated for my mapping has NOT used the dblinks. My OWB version is 10.1.0.4
This is my problem in brief.
I have installed OWB newly and started to do a sample task. I created a very simple one to one table population mapping from source to the target schema. Both are in the same database.
When i generated the code for the mapping, it gave a warning 'VLD-2771: System privileges may not allow extraction from source EMP'.
When i checked the code which was generated, i couldnot see any dblinks associated with my source table( which seems strange)
CURSOR "INGRP_c" IS
SELECT
"EMP_SRC_TRG_CONN"."EMPNO" "EMPNO",
"EMP_SRC_TRG_CONN"."ENAME" "ENAME",
"EMP_SRC_TRG_CONN"."JOB" "JOB",
"EMP_SRC_TRG_CONN"."MGR" "MGR",
"EMP_SRC_TRG_CONN"."HIREDATE" "HIREDATE",
"EMP_SRC_TRG_CONN"."SAL" "SAL",
"EMP_SRC_TRG_CONN"."COMM" "COMM",
"DEPT_SRC_TRG_CONN"."DEPTNO" "DEPTNO_1",
"DEPT_SRC_TRG_CONN"."DNAME" "DNAME",
"EMP_SRC_TRG_CONN"."DEPTNO" "DEPTNO",
"DEPT_SRC_TRG_CONN"."LOC" "LOC"
FROM "SCOTT"."EMP" "EMP_SRC_TRG_CONN" ;
In brief this is the process i have done.
Source schema : SCOTT & Target schema : TRG_SCHEMA
1) I have created source (for SCOTT) and target(for TRG_SCHEMA) modules.
2) I have also created DBLinks, Locations and Connector from source to the target locations.
3) I registered both the source location and target locations.
4) Validated, Generated and Deployed the Connector from source to the target.
I was unable to trace the error. Did i miss anything in the configuration? or during the installation of OWB.
Though it is a very old post, i hope someone can help me out here.
Thanks in Advance,
Sri
