Context object in xpath under reciver determination

hi all.
iam new to xi.
i just want to know what is the need of context object in xpath under reciever determination.
i tried a lot for understanding this context object but no way.
can any body expalin briefly.
waiting for ur great answer.
bye.
regards.
seeta ram.

suppose say you have a particular field in an xml and the xpath for the same is;
root/seg1/seg2/seg3/seg4/seg5/seg6/seg7/seg8/field, so instead of always using the whole xpath you can store it as a context object. It is like a variable say fieldcontextobject = root/seg1/seg2/seg3/seg4/seg5/seg6/seg7/seg8/field and in further development u can just ref. fieldcontextobject instead of the whole xml !!!!

Context Object for IDOC in Receiver Determination

hi,
I am trying to filter the receivers based on the vendor values in IDOC ORDERS using Context Object.
I don't see the vendor field where i could filter the value.
Any ideas would be greatful.
Thanks,
Tirumal

hi,
Conditional Receiver determaintion is possible only on the Source Message. the reason being that the integration engine will first execute receiver determiantion--> interface determiantion --> message mapping.
If you are getting the IDOC as a source, then you can use the XPATH to do conditional receiver determination.

Context object in Receiver Determination

Hi,
I am trying to use context object in receiver determination for routing messages to different receivers. From help document , I know that certain context objects are already present. Can we create our own context object in ESR and how?
I am using PI7.1
Thanks,
Neelansha

Hi Neelansha,
You can create a context object for only a request message(source), i.e, if you have a very deep nested structure then
you can use context objects which contains the XPath expression of your request message.
Can we create our own context object in ESR and how
For steps to create- go to context object - create new-->select type (int,string..)-
go to your source Service interface-click on context obj tab-select the element to which you want to assign the context obj name

please note that you have to choose interface pattern as Stateless (XI 3.0 Compatible) ,otherwise you will not be able to see the context object in Receiver determination editor.
I found the standard context objects very useful and i think we can sometimes avoid using the dynamic configuration
i have used the file name context object in expression editor in receiver determination to create a condition for routing the messages to two different Business services.

Regarding using context object in Receiver determination.

Hi All,
I want to implement a scenario where with following requirnment .
i have one sender and multiple receivers.
i have to retrive some feild value and based on the its value i have to route the message in receiver determination step by writing the condition.
for this i have a source structure , from that i read one feild , based on that feild i do lookup.(the value of destination which i am getting is at intermidiate stage not in request message)
If i define Xpath or context object it shows the request message in the contion editor , but i dnt have the destination in request message.
is there any way i can assign the Xpath for the intermidiate MT which i have created to store the destination value.
Please dont give me the link which point to help.sap page ..i have gone through it and it says that request msg only can be assigned context object.
Thanks

Hi,
In your case Enhanced receiver determination will work.A typical usage case is if you do not yet know the names of the receivers at configuration time. In this case, you can define a mapping program, for example, which reads a list of receivers from a table or from the payload of the message at runtime.
For configuration check the link

What is context objects and how we can use it Receiver Determination

hi,
i have situation here a idoc is triggered into the xi and i need to use the conditions in the receiverdetermination in that condition i need to use context object how i can use it? and what is the difference it makes and why i need to use it?
thanks in advance
Amaresh

HI,
Context objects are alternative to XPATH expressions. It is like macros in other programming langugage. If you define this , you can use this object in the receiver determination while doing conditional receiver determination

Xpath & context object

can u tell me with an example what is xpath & context object and where do we use this

Hi Sandeep,
Xpath abd Context Object can be used in Interface Determination(Configuration Object).
Consider a scenario(FILE>PI>RFC) where you have a source structure as
Field1
Field2
you have two target RFC's to be called based on a condition,
RFC1 needs to be called if field1 is '1'
RFC 2 needs to be called if field1 is '2'
In this case you would be creating two message mapping and corresponding Operation Mapping(Source->RFC1 & Source->RF2)
In the Configuration part , in Interface determination you would specify both the operation mapping. Over here you can define the condition, you can use Xpath or ContextObject for this.
I hope you are clear now what an Xpath and Context Object is how how to use it.This is just a samll example.For detailed study please go through,

Context object not visible in configuration (for receiver determination)

Hi,
I've created a context object and depending on that I want to forward the message to a specific receiver. But when in that pop-up window for the receiver determination I cannot find the context object. I can only find the technical context objects defined by SAP.
Do you have a solution for that?

Context Object not found in Integration Directory

Hi experts,
I am trying to do a content based routing scenario using BPM.
The Scenario is
ASYNC -> SYNC -> ASYNC
The synchronous step here refers to a rfc call. The response from this determines the ASYNC systems to which data should be sent.
I have declared container objects REQ and RESP accordingly in the BPM. Also have a Context object for the response.
My issue is, while doing receiver determination, I am unable to find neither RESP message type ( for XPATH ) nor a context object declared in ESR for creating an expression.
Could someone please help/guide me to resolve this.
Please let me know if I was not clear.
Thank you.

Hi,
I am on 7.11.
The problem I am facing is that I am unable to find the corresponding structure to be used for XPATH.
As mentioned, the scenario is
ASYNC -> SYNC -> ASYNC's.
I have two container variables : REq and RESP. RESP is populated after the SYNC call. The message type for the subsequent ASYNC is REQ ( step description ).
So when I do receiver determination for ASYNC, I am able to see only REQ message type for building the expression. ( Obvious )
But I would need RESP to build it.
Please advise.

Context object

Hello,
             What is context object ? where this will be used?
                                                                          shyam

Hi Shyam,
when you have a deep nested XPATH, and you need to use it in multiple locations it can become tricky and so in your IR you create a context object to refer to the XPATH.
Note: For example, you have 2 receivers (receiver1 and receiver2). You need to choose the receiver based on the vale present in any source node. Then you can use context object to choose the receiver dynamically at run time.
Create a context object in IR and assign it to an outbound interface.
In ID, while creating Receiver Determination, in condition editor you can specify the conditions.. like multiple receivers you have to specify.
Creating Context Objects --> Quite Simple.
1. Create a new context object --> Right Click on Context Object --> New --> and then give the type of the context element. Integer, char ,etc.
2. Now, go to the Message Interface and you will find the column Context object. To the corresponding XML element, give your context object name
Comparison between XPath and Context Object
XPath
/InvoiceOut/customerData/address/postalCode = 69120
Context Object
postalCode = 69120

Reg:Xpath in receiver determination

Hello,
My message strcture looks like below.
Record
Level1
item
field1
Level2
item
field2
Level3
item
field3
There can be multiple items for each level.
Here goes my condition.
I have to send the message to the receiver system "A" only when filed2 value is same across all items under level2 i.e. if there are three items under level2, then field2 should have the same value across the items.
Can you please let me know how do we impliment this in the reciver determination step using xpath?
Regards,
Rahul

Rahul,
Your scenario can be achieved using Enhanced Receiver Determination. Using Xpath in Receiver Determination might become complex for your condition.

XPATH in receiver determination

Hi,
We need to dynamically determine the receiver service based on the payload.
In the extended service editor we have succesfully used a simple XPATH expression to point out a specific field of the payload (just like using af context object) containing the service name.
However, in most cases the service name is a substring of a field of the payload and furthermore a constant is to be added to give the full service name. We have tried to solve this problem using the XPATH functions 'concat', 'string' and 'substring'. But as soon as we add just the simplest function to the XPATH expression, the receiver determination fails (unable to process the XPATH).
We have tested the XPATH with the actual message using XML Spy, and it works well.
The XPATH expression is: "concat('SAPR3_', substring(string(/p1:receipt/p1:identity), 2, 5))"
Any hints?
Regards
Lars

Hi Lars,
I just noticed, that you are talking about extended Service Editor - not a Condition - so my answer above is obviously rubbish.
What remains true is that the XPath you use has to result in a node, than the nodes string is taken as a service.
So I am afraid there is no easy solution for your problem...
If you do not have too many receivers and this list is rather static, you could of course use conditions in the receiver determination - something like:
receiver service = SAPR3_b if /.../ = abc
but this is of course not really applicable if the list of possible receivers gets too long.
Another possibility would be to use the substring as a receiver within the configuration. So take it from the payload in the receiver determination and use this 'service' for interface determination and receiver agreement.
Than, within the receiver agreement you can exchange this name by the 'real' name in the header mapping (which is performed as the very last step in the pipeline). Since you have a receiver agreement per receiver anyway, you would not have to create additional configuration objects. The downfall is of course, that to 'read' the configuration (or the message monitoring) one has to know about this mapping trick...

Context object problem

hi,
i have created a context object of type xsd:string and have assigned to a Message interface and have activated the change list.
In Integration directory when i am configuring the receiver determination i wanted to specify a condition.
i cannot see the context object in my condition editor. my sender is a business system with an SLD entry.
but if i use my sender as a business service i can see the context object.
my question is why cannot i see the context object when the sender is a business system.
appreciate ur response
thanks

Hi.
I'm having the same problem.
Mi sender is a business system with a ZBAPI. R3->XI (BPM)
I've created a context object and assigned to a field of ZBAPI.
When i create the receiver determination, as sender i put the R3, with the ZBAPI and as receiver, i've got a BPM. When i try to set the condition, i cannot see the context object neither ZBAPI in Xpath.
I have only one software component and i would like to use this context objet in order to set the BPM that will continue the process.
Thanks.
