Lookup value mapping table through message mapping.

Hello All,
I am working on a graphical mapping (message mapping). When trying to map the source message to the target message, I need to find out it a particular key exists in the value mapping table. Depending on the result, I need to map different source fields to the target field.
Is there any inbuilt function which will allow me to do a lookup on a value mapping table, or is it possible to lookup a value mapping table from a UDF?
Please help!
Warm Regards,
Keerti

Lookup into R/3 table during Message Mapping

Hi all,
I have a field in my source message that I need to convert. The corresponding values are stored in an R/3 table. I could use a 2:1 mapping in a BPM to merge an RFC call reading the table with my mapping, but I was told that this can be done without using BPM.
Can anyone describe me this ?
Thanks in advance.
Best regards,
Julien

Hi Julien,
Starting SP13 you can perform RFC lookups within your mapping using standard RFC API.
Check this michal's document for the same...

Delete all the entries in target table when message mapping?

Hello Gurus,
I have a requirement in the project. When I do message mapping, I need to delete all the entries in the target table and then insert the new rows. From searching the old posts, I know it is possible without BPM. Can anyone please help me out? I really appreciated it.

Is there a limit on the number of Key Lookups against a table in a mapping

I'm using OWB 11.1 and have a mapping with 15 Key Lookups against the one table. When I Validate the mapping it objects to a Key Lookup not being connected, even thuogh in the mapping all the Key Lookups have been renamed to their relevant fields?
Is there a limit to the number of key lookups against the one table?

Thanks for the replys.
I'm getting a validation error, so can't run the mapping. Error VLD-1108: Operator Key_LOOKUP is not properly connected.
The issue is solved, after checking each of the Key_Lookups, one was not connected to an output. The error occurs if an output field isn't used (connected to) a table or other operator.

XML Unbounded values into one field - Message Mapping

Dear All,
I am trying to convert an unbounded multifield XML structure to a 0.1 field so that the maltiple values are mapped into a single fields in semi-colon seperated fasion.
The source:

XSLT Mapping and Graphical Message Mapping

Hi,
Can any one let me which is advatageous and why or let me know where I can find docs.
Thanks In Advance.
Yaseen

Hi Udo,
I have used a lot of XSLt outside and from my own experience(java/c#) we have been hit very hard with performance when using XSLT, it is an interpreted approach.
It may look easy, fast but in time you will pay the price. Java and ABAP mappings are compiled, and only the runtime is maintained.
Is XSLT useful, sure it is, there are many things that can be done in XSLT that is very tough to accomplish using mappings.
Should it be the first choice of development, no its a case by case basis.
Most common disadvantages of XSLT are
-Scripts rapidly explode in size
-Quite complex
-Hard to debug
-Slow processing
There is an ever ending debate on pros and cons of XSLT. It upto individual Architect to decide whatz best for the interface at hand.
cheers,

Difference of FixValues and Value Mapping in Message Mapping

Hi
I would like to know the exact difference between the "FixValues" and Value Mapping. And the Scenarios of usage.
If i use Value Mappings, value mappings more for fixed values or can they be used for business data that will change ?
If the flow is from "Non SAP to SAP System" then if i maintain the "Value Mapping Tables" in Message Mapping, Do i need to maintain the same Value Mapping tables on SAP System. If this is the case, it will be over head of maintaining on both sides.
More thankful if you clarify my doudt.
Regards
Shailaja

Hi,
your question is best explained in the following link(PDF).
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/9202d890-0201-0010-1588-adb5e89a6638
Its given in the 75th page.
>>If the flow is from "Non SAP to SAP System" then if i maintain the "Value Mapping Tables" in Message Mapping, Do i need to maintain the same Value Mapping tables on SAP System.
I think this is not needed.its not needed to maintain value mapping tables in SAP system.
hope this helps.

Local lookup in message mapping

Hi all,
I've a table on the SAP PI system filled with data. From my message mapping, I want to do a lookup.
What's the best way to perform this lookup.
Again, this is a local table. So not a table residing on the SAP ECC system.
Thanks a lot.
Dimitri

Hi,
>>>I've a table on the SAP PI system filled with data. From my message mapping, I want to do a lookup.
What's the best way to perform this lookup.
the best/easiest way would be to use ABAP mapping (right after your message mapping - as in interface
determination you can have many mappings)
just to do the lookup in XI table (in abap mapping you juse use a select to get this data)
so map the data in message mapping
then do the lookup in abap mapping just for this one field

Data lookup in R/3 database from message mapping

Hi,
I am trying to lookup R/3 database from Message mapping.
Instead of creating Java class outside XI and then importing into Integration Repository, I have defined an advanced function in message mapping and trying to connect to R/3 using JCo API. But System is giving syntax errors as listed below:
Check Result for Object CustomerDetailsMap Source code has syntax error:

Can somebody help in rectifying the problem?

Hi,
can u post the java code which u have used in mapping.
There is a doc in XI-Articles. "How to Perform SAP Data Lookups Within XI Mappings" By Jerome Delune 16 October, 2003. Try looking at this article and do ur mapping.
Hope this helps you.

Get the mapping values from one message mapping into another message mappin

Hi All,
I created two graphical message mappings. In first message mapping i created one user defined function and set one global container parameter and I need to use this parameter in my second message mapping user defined function. But the global container parameters can be used in different user defined functions in same message mapping. So is there any way to use the values which are set in one message mapping into another message mapping. If yes, please help me how to get?

Hi Koteswara rao,
As you said global container parameters from first message mapping are not accessible from second message mapping program.
i haven't faced situation like this.but, if you have some unmapped field in target message in first message mapping,you can put global variables data in that unmapped field.
anyway the output of first message mapping would be input for 2nd messages mapping,so you can access global data(unmapped field filled with global data in 1st MM) from 2nd mapping program..
Cheers,
Jag

RFC Call in Message Mapping

My variables for my UDF is:
public String UDF_RFC(String DBTABLE,String MATNR,String FIELDS,String businessSystem,String communicationChannel,Container container)
And my Code:

Problem while using Parameters in Message Mapping in Multi Mapping Scenario

Hi,
I am working on a scenario in PI 7.1, in which I need to pass output of Message Mapping as an input to ABAP Mapping.
In Message Mapping, I have used standard RFC Lookup function to call a Function Module from ERP system. For using RFC Lookup function, I have created a Import Parameter of Category "Adapter", and Type "RFC" in the Signature Tab of Message Mapping.
In Operation Mapping, I have specified both the mappings (that is., Message Mapping and ABAP Mapping).
In Interface Determination, I have also assigned a value to the Importing Parameter.
But whenever I trigger a message, it fails and gives message "The input-parameter Rec_RFC_ERP does not exist." (Rec_RFC_ERP is my Input Parameter name).
When I am using only Message Mapping in Operation Mapping; it's working absolutely fine that means something needs to be done with ABAP Mapping.
Any help will be highly appreciated.
Regards,
Varun

Rec_RFC_ERP is this the name of your RFC lookup adapter?? Did you test your mapping in Design time using the RFCAdapter dropdown???
