About value mapping

What is value mapping ? when it is used ?

HI,
A perticular object/field could have different interprtations from applications to applications and Business to Business. For e.g Suppose a particular document XYZ has an identity code 001 in one application or may be in one orgnization. But the same document could have different ID in different applications.
With the help of Value Mapping you could map these IDs with each other, thus while transaction of the data XI will act as an smart mapper to pass the Application specific values.

Value Mapping in PI 7.1

Hi All,
Please tell me about value mapping.I have never worked on value mapping earlier.Please give me the steps to do value mapping.
Thanks in advance.

Hi Shweta
Please see me answers below,
1.Can we do the value mapping in Graphical Mapping?Is there any standard function available for that?If so what is it?
Your question is not clear but I will answer both ways.
If you are talking about create Value Mapping from the Integration Directory. Answer is yes. You can create value mapping groups there.
If you are talking about using Value Mapping in the graphical tool. Answer is yes. You will only see results in runtime (up to PI 7.0). In PI 7.1 you can see results during development time, after some configurations.
2.Do we need to maintain any value mapping table in ID?If so then where and how to create it?Where actually do we need to mention it?
You can do it either in ID or you can upload your values into Cache via Value Mapping Replication. (Let's say in a massive way).
In ID just create a new Value Mapping Group. That will create the values in Cache.
In IR, in your mapping, use a ValueMapping object (found under Convertion Functions) and fill it in with the values used to create the object in the ID.
I also have a document step by step for Value Mapping Replication if you want to.
Good Luck.
Luismier.
Thanks in advance.

Value Mapping and Lookups

Hi all,
I know something about Value Mapping.
And I heard that the Lookups (DB and RFC) are types of Value Mapping.
I am confused how value mapping is related to lookups.
Request you all to provide me some information regd.this.
Thank you.
Regards
Krishna.

Hi,
All the links above are quite useful in understanding Value Mapping and RFC lookups.
Both solutions could be used for getting values from R3 tables at runtime. However, there's difference in way both operate.
RFC lookup is performed at runtime, since it is executed from the UDF in message mapping. Thus at runtime, call is made to R3 table and value is fetched.
In value mapping replication, Value Mapping program is run from SAP R3 and values from table are updated in XI Runtime Cache. Thus at runtime, while performing message mapping, call to R3 system is not made. Values are available in XI cache.
Thus, it is quite obvious that Value Mapping is more performace efficient since it doesn't make a call to SAP R3 system for each incoming message. If the table data does not change very frequently(since for every change value mapping scenario has to be run for update of XI cache), and it is not very large, then it is a good option as compared to RFC lookup.
However, in cases where either data is frequently changing in table or the volume of data is too large, RFC lookup should be prefered choice.
Hope it would be helpful.
Thanks,
Bhavish

Value mapping.

hi
sdn experts,
could you please explain about value mapping?
where the value mapping is used?
thanks in advance.

Hi Chinna Rao,
Value mapping means mapping the data of some source fields to some target fields, in this mapping data can be transform in the format you required for your target system. You can do a value mapping simply by graphical mapping, using UDF etc
Go thru this thread which talks about value mapping:
Value mapping
Value mapping : value mapping function to map different representations of an object to each other. You save the mapping rules for different objects in a value mapping table.
we have two types ,
And Value mapping is used to map different representations of an object to each other.

Value mapping in the adapter module

Hi all...
There was been alot of writing about value mapping in many different ways.
But I have not been able to find help about doing the lookup in the adapter module.
Has anyone tried this?
Regards Peter

Hi,
In this case you can perfrom a RFC Lookup, but, from an Adapter Module, you would need to use the concept of JRA to do the same.
Amol Joshi has described how he called the Alerts RFC from the adapter module in these blogs and you can apply the same logic for your case as well to trigger the RFC from your module, get the data and then do the needful.

Value Mapping in PI 7.0

Hi All,
I need to implement the value mapping.
The mapping rule for the value mapping is for varius z tables like
ztable1
ztable2
ztable3
ztable4
ztable5
ztable6
ztable7
Can you please help me in implementing the value mapping ?
Can you please tell me the steps to umplement it?
Thanks in advance

How can I come to know about the Agency and Schema to implement the Value Mapping?
Check the blog # 5479
From the blog:
Enter Value Mapping Properties such as Agency, Schema for Source and Target messages. Any arbitrary string value can be
used. But enter the Value Mapping Context as http://sap.com/xi/XI
I am not getting which Value Mapping should be done for my mapping requirement,but I thibk it should be for the fixed value,but dont know whether I need to implement the Valume Mapping replication or not?
If you give more details about your requirement then somebody may help you out on the approach.

Dynamic value mapping

hi,
can u plz explain about Dynamic value mapping and where it actually use this
thanks
guna

Hi ,
Dynamic value mapping.is nothing but
It is FixValues and ValueMapping under Conversion Functions.
Eg:
You need such a requirement. Where the values in the source are mapped to someother value in the target as below.
1--> Mr
2--> MS
3--> MRS
FixValues is used when you know the entire set of Key value pair in the Design Time. You give the Key and the value in the FixValues and the mapping checks and maps the values to the target.
In the case of Value mapping, you maintain this Key - Value pair in the Integration Directory and thereby make changes easily and also use them in the Mapping in IR

How create a Value Mapping Table in XI 3.0?

Hi:
    I wish make a single sample scenario where receiving data must be converted according to convertion table:
01 -
       Legacy A | Legacy B -
M
             Male:              01     |    M
             Female:            02     |    F
And I don´t know how build it. Must I create anything in Integration Repository? (any special message mapping or function?).
Anyone know about weblog where explain step by step for "value mapping group" and "value mapping tables" creation?
Help me please.
Regards!!
David.

Hi David,
You can create value mapping tables in Integration Directory.
First you have to create Value mapping group using menu Object>new>Value mapping Group
to Display value mapping you have to use Tools--> Value mapping.
Also refer to following link on help.sap.com
http://help.sap.com/saphelp_nw04/helpdata/en/13/ba20dd7beb14438bc7b04b5b6ca300/content.htm
In IR Graphical mapping tool, use the standard function Conversions-->Value mapping.
Hope this helps.

Value mapping with 100's of values then what to do.?

Hello Experts,
VALUE MAPPING is fine with 10 - 30 values that we can achieve by manual entry, but what to do if the values are about 100 - 200.?
Kindly help me in this regard.
Thanks in advance.

I had this issue before. I entered 3-4 values and then exported the map as .mte. Edited the .mte file to populate the rest of the values & then re-imported it...

Value Mapping causing problems in Adapter Engine?

Hello, I was hoping someone might be able to help me with a problem we are having in our XI system. I created a new value mapping group that has N:1 values. There are about 80 different values that I convert to 1 value. I have been using 1:1 value mappings successfully and I tested out the N:1 scenario just fine also. However, at the time I activated this new value mapping group, all of my resulting messages in the adapter engine are being held in a status of 'To Be Delivered'. There are no errors in the RWB and the BASIS admin cannot find any errors in the J2EE logs. Does any one have any ideas on possible causes for this condition?

This problem has been corrected by a restart of the J2EE engine. Still not certain what the root cause was, but this is the second time a restart has fixed a problem coinciding with a value mapping group object activation.

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.

Modify entries of Value mapping table fromValue mapping replication

Hi,
I have successful uploaded value mapping table from external source(SAP Table) using value mapping replication. The entries are displayed in the cache monitoring.
Now what should i do,if i have to modify the entries in the value mapping table.I tried uploading the new entries using the same GUID, Agency, Schema.... but now both the previously uploaded and the new entries are dispalyed in Cache monitoring.
But i want only the new entries to get reflected in the value mapping table. So kindly request anyone to help.

Value Mapping and graphical mapping

Hi all
I am learning value mapping and
all function used in graphical mapping ..
can anybody send me inforamtion regarding tht.
Any link appericiated.

Hi Nagsen,
Mapping is basically done to convert one form of xml into another form. This can be done using either of them mentioned below.
- Graphical mapping
- XSLT mapping
- JAVA mapping
- ABAP mapping
To know more about each of them please go thru the following links. And if you ask me your which is better, it depends basically on the scenario you implementing and the complexity involved. Anyways please go thru the following links:
