Anyone worked on Value Mapping Replication for Mass Data

hi all,
Is there any one who worked on Value Mapping Replication for Mass Data stuff.
What is this?
The on page 139 of the doc below tells about registereing
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/627d1cbc-0601-0010-aea2-c275521673f2
Can any one explain guide me in that direction.
reg,

Naveen,
Have a look at the weblog /people/sreekanth.babu2/blog/2005/02/23/value-mapping-replication

Value Mapping Replication for Mass Data - Performance Issues

Hi All,
We are looking into Value Mapping Replication for Mass Data. We have done this for less number of fields.
Now we might have to have 15,000 records in the cache for the Value Mapping. I am not sure how this would effect the Java Cache and Java Engine as a whole.
There might be a situation where we will have to leave the 15K records in the cache table on Java Engine...
Are there any parameters that we can look into just to see how this hits the performance.
Any links/ guidance in the right direction might help me..

Naveen,
Check jins reply in this thread (they have done with API and without API using graphical but still some issues):

Value Mapping Replication for Mass Data

Hi SDN,
I have to design an interface in XI 3.0 (SP14 on AIX) for replicating mass data from file databse etc to the XI runtime cache.
I went thru the follwing weblog which proved to be helpful:/people/sreekanth.babu2/blog/2005/02/23/value-mapping-replication
ValueMappingReplicationOut being my Asynchronous outbound interface and ValueMappingReplication being Asynchronous Inbound Interface of in the software component SAP BASIS, software component version SAP BASIS 6.40 in the namespace http//sap.com/xi/XI/System.
Am aware that for this scenario the receiver is predefined (it must be on the Integration Server).
My question here is how do i use the outbound interface to send data to XI. I mean in my case i have a file and SQL server as the sender.
Can somebody detail the steps involved. Suppose i dont want to use ABAP proxy or JAVA proxy HTTP adapter sending the message,
Do i have other options to send data to XI value mapping interface?
Regards,
Vineet

When you want to send data from a file, just map the structure from the arriving XML to ValueMappingReplication. There is no need for using the interface ValueMappingReplicationOut or use an ABAP proxy.

Cache update in value mapping replication

Could anyone let me know when value mapping replication of mass data is done , the updated values in the java runtime cache that we can view in RWB->Cache Monitoring->Mapping Runtime Cache - are they deleted on system restart or are persisted somewhere.Is it only cached in Java memory and after restart we need to re invoke the scenario again to update the same.

Duplicate Value Restriction in Value Mapping Replication

Hello Everyone,
I was working on Value mapping replication interface which was working fine. But the value mapping replication was allowing duplicate values which are already existing. We are using this value mapping in other interfaces. But because of multiple entries exists for the same values the value mapping was giving blank value as a response. It was not giving any value even though the values are exists in value mapping table. can any one let me know how to restrict duplicate entries in value mapping replication.
Regards,
Raju

Hi Arun,
could you provide the whole command sentence for the JS to set the filter value? I am not sure what value to specify for 'All'. It is actually 'no filtering', I understand. But what is this value to set for 'no filtering'? Must I use both dropdown.value and dropdown.text or could I just use dropdown.value?
So, I cannot disable 'All' as I need to use it specifically as 'filter' value.
Pls advise.

Value Mapping Replication - Issue - Authorization Error

Hi all,
I am trying to do value mapping replication of the data from a table in ECC system using an outbound proxy on ECC and ASync Inbound interface on XI - valuemappingreplication.
Steps followed:
1. Created Table Stucture and did write a report to extract the data from the table in ECC to send the data through Outbound proxy.
2.Followed this blog - Value Mapping replication
When tried to execute the scenario after all the steps in the above blog, we have an error in sxmb_moni saying that the authentication failed. I used pisuper, pidiruser in the receiver communication channel
3.Generated a Java Proxy for the valuemappingreplication interface.
4.Tried to deploy the .jar from the above step using SDM, I was not able to deploy it.

All,
For the value mapping replication,
I have tried to send the message to URL directly for RWB, Test Message in the Component Monitoring http://server:50400/MessagingSystem/receive/JPR/XI.
I am getting an error saying that:
Delivery of the message to the application using connection JPR failed, due to: com.sap.aii.af.ra.ms.api.RecoverableException: Interface urn:flatfile:to:flatfile#MI_EMP_FILE_ASYNC_OUT not registered: com.sap.aii.proxy.xiruntime.core.XmlRecoverableException: Interface urn:flatfile:to:flatfile#MI_EMP_FILE_ASYNC_OUT not registered
Can anyone throw some light on this.

ABAP program and FB for value mapping replication

Hi,
we are using a 40B system and I want to use the value mapping replication in XI. To refill the data into the XI database I must write an ABAP and a function module to transfer the data out of R/3 into XI (via RFC). Has anybody an example how the program (and the FB) must look like? i.e I want to read table mvke and extract the materialnumber and the prodhierarchy.
Thanks and best regards
Arnold

Hi Arnold,
First you need a table type with a structure like follows:
operation
groupid
context
identifier
agency
scheme
(corresponding to the Interface ValueMappingReplication)
All used data elements should have type string or charXX
for example: operation - char10, groupid - char32, rest - char120
Next you create a function module with attribute 'remote-enabled module'.
The import parameter is your new table structure.
Next you create an ABAP program. Here an example:
report z_value_mapping .
tables mvke.
data:
p_value_mapping type zvalue_mapping,
p_value_mapping_table type zvalue_mapping_table.
p_value_mapping-operation = 'Insert'.
p_value_mapping-context = 'http://xi.com/Material'.
select * from mvke where matnr between '170' and '501'.
check not mvke-prodh is initial.
* Create a value mapping group to join two entries.
* use a unique 32 digit number.
concatenate '00000000000000' mvke-prodh into p_value_mapping-groupid.
translate p_value_mapping-groupid using ' 0'.
* Store the mapping source as first entry to the group
p_value_mapping-identifier = mvke-matnr.
p_value_mapping-agency = 'SenderAgency'.
p_value_mapping-scheme = 'MATNR'.
append p_value_mapping to p_value_mapping_table.
* Store the mapping target as second entry to the group
p_value_mapping-identifier = mvke-prodh.
p_value_mapping-agency = 'ReceiverAgency'.
p_value_mapping-scheme = 'PRODH'.
append p_value_mapping to p_value_mapping_table.
endselect.
* Push data to XI
call function 'Z_VALUE_MAPPING' in background task
destination 'IS_XID'
exporting
value_mapping = p_value_mapping_table.
commit work.
Import the RFC to the Integration Builder, create a mapping between your RFC and the interface ValueMappingReplication.
Check this Blog for additional steps:
/people/sreekanth.babu2/blog/2005/02/23/value-mapping-replication
Choose names for context, agency and scheme which are useful your scenario.

does anyone know what the problem can be?
is there a specific format for groupid?

Hi,
You can use FM GUID_CREATE and use 32 digit GUID.

Value Mapping Replication Vs RFC Lookup API Usage Pros and Cons

Hi Ananth,
Looking at the options you have, Value Mapping Replication might be a better option, because, by going the second route, you are just trying to simulate how a Value mapping replication works in reality.
But, when the VMR framework is readily available, why do we need to simulate it by using Java code?
Moreover, the java code approach will be triggered as many times and the number of messages that are triggered VS the number of times the VMR tables in the Java Runtime gets updated only when there is an entry that is added/modified in the SAP side (Which i feel is less frequent than the frequency of the messages being sent through XI).
Regards,
Ravi Kanth Talagana

Hi,
There are more issues you need to consider here:
1) Is this static data or will it change often (the lookup data);
2) Wether it is a good approach to keep it in middle system? if so who takes the ownership of managing it i.e. update, delete etc from time to time
3) The tables don't seem small to me for value mapping
I am not a big expert but i am off the opinion going RFC way as it will keep loose-coupling in place.
However your issue for not using graphical RFC is not true though, you can pass all your line items as a single object which means only making ONE single call to ECC and then get the return the same way. Think along the lines of internal table as an object

Value mapping replication - java cache

i used value mapping replication and successfully loaded values to the java cache (i can see the in the cache monitoring but not in the configuration).
when i try to use a scenario with value mapping using the agencies and schemes which i loaded, the mapping doesn't work and i receive the same value that was entered.
what could be the problem?
P.S
i used the same groupid for each pair of source and target value when i loaded them. is that the right way?

Tomer,
what is the context that u used. Did you give the correct context in mapping as in Runtime Cache.

2) There is an issue with SLD access when I look at the JPR monitoring,could be the possible reason.

Value Mapping Replication - 7.31

hi,
 working on a requirement of value mapping replication on 7.31 environment.
 I have used the standard - ValueMappingReplication service interface as the receiver as it is an async scenario.
 My sender structure is similar to the ValueMappingReplication. I am using a SOAP UI to hit the PI server. I have downloaded the WSDL from the ID and used it as a request.
So it is basically a soap sender ( from SOAP UI ) to SOAP Receiver - async. - I am using Transport Protocol - HTTP and Message Protocol - X13.0
I have registered the URL -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 (for the asynchronous replication scenario)
--- how do i hit the Java proxy servlet ? to update the data on PI runtime cache?
- wht url should i use ? -/MessagingSystem/receive/JPR/XI/http://<Server>:<Port>/ - is this correct ?

Hello,
Use this URL in SOAP receiver channel
http://<host>:<port>/MessagingSystem/receive/JPR/XI
Thanks

Value Mapping replication GUID Logic

HI,
We are doing Value Mapping replication from ECC table entries to Pi Runtime Value Mapping cache.
We are generating the Group ID required for Value Mapping from ECC.
Here we are confused with the logic for GUID Generation.
At first I thought the driving factors are -- if there is already an entry for the same Source Agency, Source Scheme, Target Agency, Target Scheme and Target Value then it should go in the same group id, else a new gr id needs to be generated.
However it looks like that is incorrect.
Can somebody help us on what should be the logic for generating group id for Value mapping replication.
We have the scenario where the same source Agency, Scheme ,Value maps to multiple target Schemes... and it is not working if we have different Group ids...
Thanks,
Himadri

> We have the scenario where the same source Agency, Scheme ,Value maps to multiple target Schemes... and it is not working if we have different Group ids...
If you want to have multiple targets, then you have create pairs with unique GUID
like this:
A - 1 GUID X
A - 2 GUID Y
A - 3 GUID Z
The standard value mapping function does not work, when you have multiple targets. It will not return an entry.
You have to create a UDF for this purpose. You need to identify which target do you want to select from different values.
An UDF could look like this extract:
IFIdentifier source = XIVMFactory.newIdentifier(source_context,source_agency,source_scheme);
IFIdentifier target = XIVMFactory.newIdentifier(target_context,target_agency,target_scheme);
IFRequest request = XIVMFactory.newRequest(source,target,sourceValue);
try{
IFResponse response = XIVMService.executeMapping(request);
if (response.countTargetValues() > 0){
String[] targetValues = response.getTargetValues();
// take first value of result
return targetValues[0];
This example is taken from PI 7.1

Cache not updated on Value Mapping Replication PI 7.1

Hi,
I already configure an scenario to do Value Mapping Replication on PI 7.1
I am sending the xml file thru an HTTP client and it seems to go all the way down. I have a "Processed Successfully" status in the moni but the thing is that I can not see any difference in the Cache at the RWB.
My receiver agreement uses the ValueMappingReplication interface to a CC of type XI.
Any ideas on what could be wrong?
Thanks in advance.
Luis

Hi Udo,
Your reply pointed me to the right direction.
In the RWB I found out that my group-id was in the wrong format, so to be sure, I used a function module called /OSP/GET_GUID. That way I generate a correct 32-bit group-id.
Now it works.
Thanks.
Luis.

Value Mapping Replication Inbound Structure

Hi All,
I am using Value Mapping Replication to upload Value Mapping Table in runtime cache, to do this first i create value mapping manually in ID with source and target.
Source:Agency : ValCustomerNo_B
Schema : ValB
Value : xxx
Target:Agency : ValCustomerNo_J
Schema : ValJ
Value : yyy
Now try to upload 1800 record in the same value mapping table through Value Mapping Replication. Inbound structure looks like this.
<?xml version="1.0"?>
<ns1:ValueMappingReplication>
 <Item>
 <Operation>Insert</Operation>
 <GroupID>f16372c043bd11dea79f001558c985eb</GroupID>

 <Context>http://sap.com/xi/XI</Context>
 <Identifier scheme="ValJ" agency=" ValCustomerNo_J">1960457894</Identifier>
 </Item>
I do not know is this xml structure is correct for XI adapter to create correct rows in value mapping table or not?
At runtime value mapping function in graphical mapping, for manually create record in Value mapping table is coming correctly where in case VM replication record it always map to one arbitrary number.
Even when I look into runtime cache notification, manually created record comes in pair like..
Agency : ValCustomerNo_B | Schema : ValB | Value : xxx | Group ID | Context
Agency : ValCustomerNo_J | Schema : ValJ | Value : yyy | Group ID | Context
Where as record for VM Replication comes in sequence first all ValB and then ValJ, they are not in pair
Agency : ValCustomerNo_B | Schema : ValB | Value : xxx | Group ID | Context
Agency : ValCustomerNo_B | Schema : ValB | Value : ppp | Group ID | Context
u2026u2026.
Agency : ValCustomerNo_J | Schema : ValJ | Value : yyy | Group ID | Context
Agency : ValCustomerNo_J | Schema : ValJ | Value : aaa | Group ID | Context
I suspect inbound xml structure is not correct for VM replication.
