Issue with Value Mapping table

Question

Hi
I want to upload a external value mapping table to XI.
I do not want to code for it on the SAP R/3 side. and there might be more than 2000 value mappings. so can we upload a external mapping table.
Is it possible?? if yes, then how??.
Thanks
Nikhil

XI 3.0
Hi,
first of all one helpful information:
You can see all data of the value mapping tables using the
runtime workbench: Go to the IntegrationBuilder->
Integration Monitoring->Cache Monitoring, select 'Search
for Value-Mapping' and choose your context.
The value mapping tables are located in the J2EE part of
XI. You have to send your value mapping data to an Java proxy
located in the J2EE part. First, the inbound proxies
(synchronous and asynchronous) need to be activated.
There are two urls, named in the docu, you have to call
from a web browser:
(asynchronous replication scenario)
http://<Server>:<Port>/ProxyServer/register?ns=http://sap.com/xi/XI/System&interface=ValueMappingReplicationSynchronous&bean=localejbs/sap.com/com.sap.xi.services/ValueMappingApplicationSynchronous&method=valueMappingReplicationSynchronous
(synchronous replication scenario)
http://<Server>:<Port>/ProxyServer/register?ns=http://sap.com/xi/XI/System&interface=ValueMappingReplication&bean=localejbs/sap.com/com.sap.xi.services/ValueMappingApplication&method=valueMappingReplication
You only need to perform this step once (for each
installation).
If you already have a sender for the mapping data, the
next step is to configure the scenario in the directory
Create a communication channel with
Adapter type: XI
Transport protocol: HTTP 1.0
Message-Protocol: XI 3.0
Adapter-Engine: Integration Server
and host name and http port of the XI J2EE Engine and Path Prefix: /MessagingSystem/receive/JPR/XI
The user XIAPPLUSER has the required permissions.
For an asynchronous communication you can use the
inbound interface ValueMappingReplication from the namespace http://sap.com/xi/XI/System.
In that namespace there are also outbound interfaces you
can use to generate a sender proxy and synchronous
interfaces for the same purpose. Set the created communication channel as the receiver channel.
You may need a mapping and so on depending on your
sender. If you use the provided outbound interfaces there
is no mapping required.
The Data:
You can create your own GUIDs using some function like GUID_CREATE in ABAP. You don't need to declare the context you use. Something like http://mycompany.com/Test should be ok.
A sample in ABAP:
CRM and R3 are the names of the business systems.
data: lcl_value_mapping type ref to co_svmr_value_mapping_rep,
        ls_value_mappings type svmr_value_mapping_replication,
        ls_item type svmr_value_mapping_rep_item,
        lcl_system_fault type ref to cx_ai_system_fault.
  ls_item-operation = 'Insert'.
  ls_item-group_id = '315286378563858425463215845123548'.
  ls_item-context = 'http://Test'.
  ls_item-identifier-scheme = 'FormOfAddress'.
  ls_item-identifier-agency = 'CRM'.  <- Business System A
  ls_item-identifier-value = '2'.
  append ls_item to ls_value_mappings-value_mapping_replication-item.
  ls_item-operation = 'Insert'.
Use the same guid for another value of the same group
  ls_item-group_id = '315286378563858425463215845123548'.
  ls_item-context = 'http://Test'.
  ls_item-identifier-scheme = 'FormOfAddress'.
  ls_item-identifier-agency = 'R3'. <- Business System B
  ls_item-identifier-value = '1'.
  append ls_item to ls_value_mappings-value_mapping_replication-item.
  create object lcl_value_mapping.
  try.
      call method lcl_value_mapping->execute_asynchronous
        exporting
          output = ls_value_mappings.
      commit work.
    catch cx_ai_system_fault into lcl_system_fault.
      write: 'Error: ', lcl_system_fault->errortext.
  endtry.
See the XI documentation at SAP XI Design and Configuration Time -> Configuration -> Value Mapping -> Value mapping Replication for Mass Data.
Hope that helps.
