Regarding Message Inflow of JCA 1.5

Sir,
I'm new to JCA and i read the JCA 1.5 specification. It says that JCA 1.5 supports Message Inflow(i mean it supports to invoke EJB from EIS via resource adapter). Now i wants to clear one thing. That is,
is it possible to return the data from EJB to calling point of EIS?.
If not, please suggest me an alternate way to achieve this using JCA 1.5 .
Because according our requirements of EAI, EIS is expecting result after calling EJB(which is in application server).
Thanks in advance.

>>
is it possible to return the data from EJB to
calling point of EIS?. Could you please explain what you mean by "the
calling point of EIS" ? If you are referring to a
destination in the EIS, you could use the outbound
contracts supported by the RA to the EIS, in the EJB
or MDB to send back a message.Calling point of EIS may be SAP which could be c/c++ based. From SAP they may call a function(which is implemented in J2EE application) through the resource adapater. That function will implemented in EJB.

JCA Message Inflow Integration With JMS Queue

Hi,
I want to integrate JCA message inflows with JMS Queue. I know JCA Message Inflow destination can be Message Driven Bean. But is it possible to specify a JMS queue as destination of JCA Message Inflow.
i.e.
JCA -> MDB -> JMS Queue
OR
JCA -> JMS Queue
Thanks

Hi Manish,
As of now there is no out-box-adapter for JMS queue.
If you don’t want JNBridge adapter (I hope you’re referring to same. There is no “jt” adapter as you mentioned), you can create a custom adapter which access the JMS queue.
Use WCF LOB adaper (WCF Lob
Adapter Wizard)and create an adapter.
Following article details about the .NET code for messaging with JMS queue, try the code.
Use JMS Messaging in your C# Applications
And following articles give details about using WCF LOB adapter/Wizard:
What Is the WCF LOB Adapter SDK?
Sample:
https://msdn.microsoft.com/en-us/library/bb798102.aspx
http://geekswithblogs.net/michaelstephenson/archive/2009/02/10/129302.aspx
Use similar code (one from above codeproject article where how to do messaging between JMS queue is shown) to wrapper it around custom WCF LOB adapter.
Give it a try, if you don’t want to spend anything on a 3rd party adapter.

kiran

Hi Kiran
Use 'write' to display the message in the job log.
write : / log_message.
Place this statement after the block of statements in your program where you want the message to be displayed in the log.
You can see the job log in SM37 transaction.
hope this helps you.

Few Queries regarding Message Size in XI

Hi ,
I have posted the same question before many times over but did not get a satisfactory reply.
I have many file to idoc scenarioes.
Now the file size is large .It is a CSV or a Tab-delimited file.
IT can grow upto 100 mb.
DEV has 4gb of RAM
QA and PRODUCTION have 16 GB of RAM
INTEL DUAL CORE PROCESSOR ON EACH box.
If I want to send a complete 60-100 mb file I run into "LOCK table overflow"
WE have increased the table size parameter on recieving CRM system.
recordset parameter is set for all interfaces from 500 to 5000.
Since I am not able to send a complete file I am breaking it into chunks and sending as I do not have much choice.
For certain interfaces where I am having large number of fields I am able to send only 2000 records per file for others about 14000 records per file.
In order to take care of errors like "LOCK table overflow " and to automate the process I have scheduled a report 'RSARFCEX".Otherwise I'll end up putting one file at a time and wait for it to get processed (i.e. create idocs with status 64 in the recieving system.) and this takes a long time.
I see here on sdn people are able to send a large file in one go.
Even if I try to split a file using xi ..multimapping..extended interface determination...the works et cetra ...It fails for a file of size 6mb.
That too after increasing the no. of work processes.
Besides tried to follow XI tunning parameters ...but there was no change in status-quo.Finally I am using an abap program in xi which is spillting the file (in a matter of few minutes) so that file adapter can pick it up .
I am surprised by xi system's performance .I am not using BPM .There is content conversion on sender side.
Would the experts on the forum please provide a solution.

Regarding Message trace in XI

hi Experts,
I am doing file to idoc scenario.
I have idoc number with me.
Please could you guide me to find out the message for that idoc number.
File -
 XI -
 IDoc
 Idoc number
Please help.
Regards,
Vignesh

Hi Vignesh,
If you have the IDOC number then go tto SAP ERP system and see the control record of the IDOC. Go to the Details tab of the control record.
you would see a Identification field. There you would find the message ID .
for example ...0000000000653745 79196146EE036611E1000000C0A8641B. So in the above example whatever is after space is the message id(79196146EE036611E1000000C0A8641B).
YOu copy the message ID and then login to XI. Run SXI_MONITOR.
Click on Advanced Selection Criteria.
In the Message ID field enter the message id which you earlier copied.

Sumit

Regarding Message Flow in XI

Hi Experts,
I was go through the Blog given by Siva Maranani
/people/siva.maranani/blog/2005/05/25/understanding-message-flow-in-xi
But in this After sending the Xi Message from send Queue to Integration Engine...
What wi be the process inside this IE.
Please let me know
Regards
Khanna

But as per my knowledge in the IS the Pipeline services wil be done( Includes Receiver det, Interface Det, Mapping, Logical rout, Tech. routing, Call Adapter, Message Split )
It means there is no further process inside the IE??????????
Messages received at the Integration Server are processed through a defined series of steps called Pipeline Services. These pipeline services are part of Integration Engine which in turn is a part of Integration Server
Only the XI Adapter wil pick the Xi msg from Send Queue to IE.......Thats it?????/
Yes. Thats the main task of XI Adapter. It also does the SLD lookup.

then this IE wil pass this XI Msg to the IS ..... Right????????
As mentioned, IE is part of IS

Regarding Message Mapping

Hi All,
The problem is I have created 2 Message Mappings and Two Message Interfaces
Two Messages Mappings and Message Interfaces are activated successfully, my question is which Message Mapping will execute among them(Message Mapping). If it Executes latest one Message Mapping ok, if I want to Execute Old one how can I execute that. I dont know whether we can create more than one Message Mapping, if it is possible here then can I Execute any one among all these Message Mapping help me in this problem.
Thanks & Regards,
Ashok.

hi,
in your scenarios your mappings
are executed on the basis of the interface mappings
one interface mapping can have a few message mappings
that will all be executed :
/people/michal.krawczyk2/blog/2005/11/01/xi-xml-node-into-a-string-with-graphical-mapping
you always use interface mappings (in directory)
so you need to check how which message mappings
are included in your interface mapping
to find out which will be used in your scenarios

Regarding message interfaces in JDBC implementation

Hi Bhavesh,
I have been trying to implement the jDBC scenario as mentioned by you in the blog "JDBC Receiver Adapter -- Synchronous Select Step by Step",could you please help me out with interfaces(how many interfaces do we need on the whole).
Regards
Madhu

Madhu,
Please refrain from directing questions to someone in particular. There are lots of XI experts around here who can surely help and directing questions to one person is going to discourage others from answering .
Answering your question~~ refer into this blog by Arpit and use the same concepts as he has described for File - RFC - File. The only difference will be in the datatypes and message types,

Regarding message maping

hi all.
i just want some information about the following error.
here iam testing file to file scenario.
iam using same message type for source and target.
in message mpping while iam testing with xml its showing error like
10:53:38 Start of test Mapping object MM_SapIsuTo3rdpartyAccountStatementExtractions incomplete. Unable to continue execution
Structure with min!=max without mapping
can anyone help me on this.
waiting fpor your response.
bey.
regards.seeta ram.

Hi,
There will be some fields in your target structure with fixed occurances.
While doing mapping either you disable such fields or you should map it with a constant or some fields from the source structure.
While mapping from the source field please ensure that in case no values coming from the source field, you should map it with a default value.

Regarding message error in bap webdynpro

hai friends
i am new to abap webdynpro
i have doubt that , i palced the table ui element in the view
if that table is not initial
i have to give error message,
is it same way as normal abap
in the view the ui element id name of table is TABLE1
can write this way
if table1 is not initial
then i will call the message method over here through wdcode wizarad
endif

Hi,
Check the example WDR_TEST_MSG_AREA .
1. Validate your data in seperate funtion module and update the message Id and number in internal table.
2. Use wizard to declate variable for massage area. It will create data declaration for messages of interface type IF_WD_MESSAGE_MANAGER. In this interface there is a method 'REPORT_T100_MESSAGE'. Pass your message ID and number in your internal table to this method parameter.
If u need more information about message handling, check the following URL

Regarding Message Type in ALE

hi guys,
i was involved in Master data distribution using Message Types MATMAS, DEBMAS and CREMAS but never created a customer specific Message Type that is why, i just want to know in what cases do we have to create our own message type's using we31, we30 and we81 and we82.
can any one out here help me out by sharing giving some real time scenario's in what cases do we exactly have to create our own message type.
thanks
Pavan

Hi Pavan,
There is no hard and fast rule that you use standard or custom message types...
SAP has provided messages for almost all scenarios. If you don't have enough fields in standard messgae type, you can enhance it to accumulate your requirement.
But if the organization has completetly custom defined system (involving many Z-tables) , we create custom message types...
As far as my knowledge, we should try to go ahead with standard message types by suppressing unnecessary segments and enhancing existing segments just to avoid Z-objects.

Regarding Message Maaping

HI,
I have a scenarion where i have to read a file where the structure is not defined properly i.e Records are coming as continous stream of messages separated by some special ASCII charac but in that stream there is only small portion of useful information to be transmitted to user rest all the information is to be rejected .Useful Info is to be mapped to a particular message format which will later be mapped to outgoin message fields in BAPI.
Now how i should derive the useful Info from the stream of message obtained from file .File conversion is not working properly Message is like (1)(2)(3)(4)(useful Ifo)(5)(6) this is the strem of message coming as continous stream I have to map useful info to message later to be mapped
Regards,

HI,
Can plz give your exactstructure , so that it will be possibe to give answer,
I mean , yu cna difine the structure as you like is it ok, so create the one field as the length of first 3 fields and the required fields under one , and the rest under one parent nodes.
in FCC you can use give the only the middle portion of the structure only for FCC parameters
<Root>
<Block1>
onefield with 3 fields which you donot convert
</Block1>
<Block2>
Select fields which you want to convert
</Block2>
<Block3>
onefield with 3 fields which you donot convert
</Block3>
In the FCC
give the structure Root,block1,block2,block3
and the processing parameters only for the block2 not for all
