Missing Master Site in Multi Master Environment

Question

Hello,
we are using MM-Replication on three Master sites with two replication groups.
Replication support was installed and configured by the application vendor.
I do not have experience with Multi Master Replication.
The data of the RG (Readonlymastergroup) was never replicated to one Master
(DEFS01). When I queried dba_repgroup on the failing site, I found the
RG status to be quiesced. There were no pending administrative requests
on this site or the Master Definition site, but I found that there is no definition
of the failing site's membership to the RG on the MD site.
Master Definition Site
select gname,dblink,Master,masterdef from dba_repsites;
GNAME DBLINK M M-----
MASTERGROUP      DEMD01 Y Y
MASTERGROUP      DEGS01 Y N
READONLYMASTERGROUP      DEMD01 Y Y
READONLYMASTERGROUP      DEGS01 Y N
MASTERGROUP      DEFS01 Y N
Failing Master Site
select gname,dblink,Master,masterdef from dba_repsites@defs01;
GNAME DBLINK M M-----
MASTERGROUP      DEFS01 Y N
MASTERGROUP      DEMD01 Y Y
READONLYMASTERGROUP      DEFS01 Y N
READONLYMASTERGROUP      DEMD01 Y Y
MASTERGROUP      DEGS01 Y N
READONLYMASTERGROUP      DEGS01 Y N
Can anybody explain how this could happen? AFAIK adding a master to a resource
group is a distributed transaction that should be rolled back on all sites, if it fails
on one.
To correct this situation; I am thinking of removing the RG from DEFS01
with DBMS_REPCAT.DROP_MASTER_REPGROUP (on DEFS01) and then rejoin DEFS01
with DBMS_REPCAT.DROP_MASTER_REPGROUP on the Master
Definition Site.
Will this work? Anything else I have to think off?
Regards,
uwe

Hi Janos,
I have tried the Multi language scenario. You need to have following setup in your system, they are:-
>Install language pack
>You need to upload content using below CSV fles:-
multistring.csv
Material.csv
Plant CSV
Product_Plant_Relationship_template.csv
If you can share your email id I will email you sample CSV file which you can use. Or else pl follow below steps to download CSV file from system:-
Click Setup
Click System Administration tab
Click to Import data
Click to New button
select radio button Upload to Server and click next
Select any dummy excel file from local server while browsing for Upload Import file option and click next.
Select  Preview import check box adn search MultiString  from the drop down object type and click next
In the page you will see the template.csv link, click and save the file. This the file you are looking for.
Create the content and upload the file...hope this will help you!!!
There is another way of importing master data is multiple langaure. In this scenario master data source would be ECC. You need to run SAP provided standard report to export the details. This XML file you can import into sourcing system. Pl find below blog link for more detail:-
