Why asynchronous RFC is stated as asnynchronous processing type ?

in help document it stated that ,in r/3 system asynchronous RFC has different meaning...
what is that meaning?
why it stated as asynchronous processing type?

hi,
ARFC:
Asynchronous remote function calls (aRFCs) are similar to transactional RFCs, in that the user
does not have to wait for their completion before continuing the calling dialog. There are three
characteristics, however, that distinguish asynchronous RFCs from transactional RFCs:
When the caller starts an asynchronous RFC, the called server must be available to
accept the request.
The parameters of asynchronous RFCs are not logged to the database, but sent directly
to the server.
Asynchronous RFCs allow the user to carry on an interactive dialog with the remote
system.
The calling program can receive results from the asynchronous RFC.
You can use asynchronous remote function calls whenever you need to establish communication
with a remote system, but do not want to wait for the functions result before continuing
processing. Asynchronous RFCs can also be sent to the same system. In this case, the system
opens a new session (or window) and allows you to switch back and forth between the calling
dialog and the called session.
To start a remote function call asynchronously, use the following syntax:
CALL FUNCTION RemoteFunction STARTING NEW TASK taskname
Destination ...
EXPORTING...
TABLES ...
EXCEPTIONS...
I hope it helps.

Asynchronous RFC call from R/3

I need to make an asynchronous RFC call from R/3. I receive an error message in R/3 stating that my RFC destination can only be of type I (Internal) or type 3 (R/3 system). In order for it to reach XI I need it to be of type T (TCP/IP). Any help would be appreciated.
Here is the function call.
CALL FUNCTION 'Z_B2B_R3_FUNCTIONAL_ACK' starting new task 'SESSION1'
   destination 'RFC2XMBSERVICE'
      EXPORTING
           MSG_TYPE            = msg_type
           ORDER_HEADER_RETURN = order_header_return
      TABLES
           RETURNCODE          = i_return.
the RFC desitnation RFC2XMBSERVICE is of type TCP/IP which by default makes it synchronous.
Thanks,
Jim

hi,
have you tried:
CALL FUNCTION 'Z_B2B_R3_FUNCTIONAL_ACK'
in background task
destination 'RFC2XMBSERVICE'
EXPORTING
MSG_TYPE = msg_type
ORDER_HEADER_RETURN = order_header_return
TABLES
RETURNCODE = i_return.
commit work.

Error with Asynchronous RFC call to JDBC

Hi all,
We are working on a scenarion where in we have to make an asynchronous RFC call to JDBC.
We have configured RFC sender adapter following this weblog
/people/michal.krawczyk2/blog/2005/03/29/configuring-the-sender-rfc-adapter--step-by-step
We have created data types only for the database as RFC does not require any data types.
And also we have created message types,message interfaces accordingly.
In Message Mappping,we mapped the export parameters of RFC to the access fields of database message type.
Also we have created sender agreement,interface determinations etc.... accordingly
And for sending RFC request asynchronously we followed this weblog
/people/swaroopa.vishwanath/blog/2006/12/28/send-rfc-to-sap-xi-150-asynchronous
Once done with all the above steps we could able to trigger the RFC call and caught with the following errors in SXMB_MONI and no errors are seen in communication monitoring
SOAP Error:

the above errors are shown as part of request mapping..
Can any one please let me know what other configurations do we need to do?
I did not map the RFC import parameters,do we need to do that
Any help in this regard is really appreciated
Rgds,
Santhosh

Hi,
I am really happy to hear that the problem with mapping is resolved.
Now as per your requirment It needs to be aynschornous RFC--> XI ---> JDBC call. In XI you should map the RFC Export parameters to the traget structure of JDBC.
then the question is to how to trigger the RFC Function Module in R/3 to XI.
Plesae follow below steps to trigger it from SAP R/3
1. Create a RFC in the R/3 system
2. Configure the SM59 and Sender Communication channle as given in the Michal's blog. Also test if it is succesful.
/people/michal.krawczyk2/blog/2005/03/29/configuring-the-sender-rfc-adapter--step-by-step
3. Import the RFC in XI
4. Do the mapping to the target strucutre
5. Configure the JDBC receiver adapter
/people/sameer.shadab/blog/2005/10/24/connecting-to-ms-access-using-receiver-jdbc-adapter-without-dsn
6. You can trigger the RFC from R/3 sytem by using
Async Call - in ABAP program use below syntax to call RFC. Here the export parameters will be passed on to XI which further have mapped to JDBC.
CALL Function "RFC Name" IN BACKGROUND TASK destination <sm59 destination>
COMMIT WORK.
Sync Call
CALL Function "RFC Name" destination <sm59 destination>

Asynchronous RFC

Hi,
Im using rfc_abap_install_and_run function module to create abap programs and function modules remotely from non-sap sytem i.e. ( Through JAVA beam).
Here, my requirement is that i want to run this function module paralelly i.e. Asynchronous RFc.
So, how can i use this function module and make it as 'starting new task' or any thing that should execute it parallelly many fm and create the required one..
As of now, it is getting error like user is editing...
I think you understood the problem..
Awaiting your response.
Thanks
raja

Hi,
So a maximum of six sessions can be opened.. so how can a user from JAVA can identify then the next i.e. seventh task should be again reset to first and then process it in a loop of 1 to 6.
Is that pssble from JAVA end..
thanks

TRFC and Asynchronous RFC

Is there any diff between TRFC and ARFC ?
Is TRFC another name for ARFC?

Hi,
Transactional RFC (tRFC) they are previously known as ARFC
Transactional RFC (tRFC, previously known as asynchronous RFC) is an asynchronous communication method that executes the called function module just once in the RFC server. The remote system need not be available at the time when the RFC client program is executing a tRFC. The tRFC component stores the called RFC function, together with the corresponding data, in the SAP database under a unique transaction ID (TID).
If a call is sent, and the receiving system is down, the call remains in the local queue. The calling dialog program can proceed without waiting to see whether the remote call was successful. If the receiving system does not become active within a certain amount of time, the call is scheduled to run in batch.
tRFC is always used if a function is executed as a Logical Unit of Work (LUW). Within a LUW, all calls
·         are executed in the order in which they are called
·         are executed in the same program context in the target system
·         run as a single transaction: they are either committed or rolled back as a unit.
Implementation of tRFC is recommended if you want to maintain the transactional sequence of the calls.
Disadvantages of tRFC
·       tRFC processes all LUWs independently of one another. Due to the amount of activated tRFC processes, this procedure can reduce performance significantly in both the send and the target systems.
·       In addition, the sequence of LUWs defined in the application cannot be kept. It is therefore impossible to guarantee that the transactions will be executed in the sequence dictated by the application. The only thing that can be guaranteed is that all LUWs are transferred sooner or later.

Why is it taking so long to process my order?

Hey, I ordered CS6 Production Premium from the Education store on the 13th of September and my order staus is still pending.
I also uploaded my college ID on the Customer Support Portal on the 16th and it says "Pending Adobe Response".
Could anyone help me out here as to what's going on. Why is my order not being processed? Its becoming quite frustrating waiting for the order to be processed when it said Adobe would respond to my case within a couple of days of me uploading my college ID and dispatch the software soon after.
Can anyone help me out as to why its taking Adobe so long to process my order and how much longer do I need to wait before I can finally use the software...
Thanks.

Well, anybody who buys the software should be able to start using it right away by downloading and running the 30-day free trial for the product...
As for student academic validation, Adobe says it should normally take about two business days:

How to call Asynchronous RFC

Hi Everybody,
 Could yo pls guide me on how to implement asynchronous RFC. When i run my RFC using Report :
CALL FUNCTION 'Z_HR_NO_ALTINN_TX' DESTINATION 'Q3A2X7A'starting new task 'test'
exporting
 PASSWORD = 's'.
I get the error saying :
What happened?
 When executing the asynchronous RFC, the RFC destination "Q3A2X7A" had
 neither an internal (connection type 'I') nor an R/3 communication
 type (connection type '3'.
 Error in ABAP application program.
 The current ABAP program "Z_ALTINN_TEST" had to be terminated because one of
 the
 statements could not be executed.
 This is probably due to an error in the ABAP program.
Error analysis
 A typical cause of error is the
 execution of external programs (RFC destinations of the type
 TCP/IP) via asynchronous Remote Function Call (RFCs with the
 addition 'STARTING NEW TASK taskname').
 RFC destination... "Q3A2X7A"
I would like to know if async RFC call is possible to XI.

Raj

Hi,
you need to call the RFC from ERP, R3
with
call function XXXXX
in background
and Commit work.

Why does it take 12 hours to process a 2 hr. in imovie 11

Why does it take 12 hours to process a 2 hr movie to quick time?

iMovie is designed to create simple home movies, not theatrical-length features.
iMovie does all rendering in a single pass when you share the movie, so the longer the movie and the more complex the effects used, it can overwhelm the memory in your computer. I would normally say keep your movies to 30 minutes or less, but there is always an exception to the rule. Some people are able to get more.
If you are able to complete a 2 hour movie in 12 hours, you must have a pretty powerful Mac. Many Macs would crash long before then.
Final Cut Pro X is the tool for theatrical length movies. Final Cut Pro X allows rendering to occur in smaller chunks, so it doesn't have to happen all at the end. When you share the final movie, you are patching together many segments that have already been rendered.
However, as I learn FCP, I have discovered that most pros do not edit a 2 hour movie on a single timeline. They create it in logical scenes, and then only put them all together at the end. They do this for performance reasons, and so in case something goes wrong, the problem is isolated. When they get ready to create their final 2 hour movie, they drag completely rendered scenes to a clean timeline and output the final movie.

Asynchronous Coupling with Pools in one Process

Hi everybody,
i try to call a BPM Pool (POOL_B) by another BPM Pool (POOL_A) within the same process but unfortunately without success.
This are my steps:
a) for my START Event (Pool_B) i created a new Message Trigger with a Asynchron Service Interface (Wsdl File with two import parameters)
b) in my Service Activity (Pool_A) i use the created Asynchron Service Interface in order to process Pool_B
c) in Pool_B i have also created a Notification to get an info Mail after the process was started
d) i add SAP_BPM_SuperAdmin to SAP_BPM_Service
e) Consumer and Provider are also be configured
After starting the process i didn't get an info Mail, but everything in Pool_A seems to work fine.
If i activate Pool_B (Pool_A becomes inactive) only the WS for Pool_B works.
Please Help.
regards,
Sid

You need two Physical databases each with its own Connection Pool, within that database will be a single Physical Schema.
Or you could have a single Database/Connection Pool if it has read access to both schemas.

Receiver ASynchronous RFC

I need to develop an Asynchronous RFC Receiver side? How should I accomplish this?
appreicate your help.

Hi Mohan,
no, you dont call the RFC direcly. You just trigger a message, what ever you like, to XI. The inbound interface - your RFC - will be found by the interface determination of you IB directory. The ABAP call is made by the RFC adapter (you have to configure that RFC communication channel like described in <a href="http://help.sap.com/saphelp_nw04/helpdata/en/33/c6e63b60c25767e10000000a11402f/frameset.htm">SAP library: RFC-Adapter</a>) who translates the XML to DIAG protocol.

Asynchronous RFC vs synchronous RFC

Hi Experts,
Can you give me what are the differences between asynchronous RFC and synchronous RFC?
thanks.
Moderator message : Not enough re-search before posting. Thread locked.
Edited by: Vinod Kumar on Jul 4, 2011 4:45 PM

Gabriel,
synchronous
the sender sends a request message to the receiver and waits for a response message.
for eg. consider a scenario.. where u have a customer no. and u need customer details.which is stored in R/3...so u can configure a HTTP to R/3 synchronous scenario... a http request will be sent to R/3 having a CUSTOMER NO....and in response u will get details of customer like...cust name,address, etc...
asynchronous
sender send a request message but doesn't wait for response.
for eg consider a file to file scenario .where u need to pick a file from a source location to a destinartion location....so...it will asynchronous interface
hope u r lil bit clear!!.

Process Chain (0TCT_C21) Statistics - Why Process Type sometimes is blanku2026

I am looking at 0TCT_VC21. A process chain was run, it shows Process Type as Blank (which shows up Query as Not Assigned). Does that mean when process chain was run, it failed or so thatu2019 why process type is blank. I am also seeing frequency column shows result as negative...e, 3,000-. What does negative number mean? Appreciate any help.

Which process type is it showing blank. Did you difine the process properly?

Processing Type In PPP

Hi All,
As we are upgrading from 11i to R12 and we are configuring payments in R12, and we have four payment method:-
Scrren shot i have attched
1) Check
2) Electronic
3) Wire
4) Clearing
And we are configuring Payment Process Profile (PPP) in payment administrator and there is one LOV/column at PPP's header level called: 'Processing Type' which has only three seeded value available i.e. Electronic, Printed & Payment Card, so for payment method 'Check' we use this as 'Printed' and for 'Electronic' payment method we will use 'Processing Type' as 'Electronic'. So we have few doubt here:-
1) What is the purpose and meaning of the column: 'Processing Type' at the PPP header level?
2) Does it means that for 'Check' payment method we should choose only and only 'Printed' option and for 'Electronic' payment method we should select only and only 'Electronic' ,does this options is linked to these payment method?
3) We have remaining two payment method: 'Wire' and 'Clearing' for which we need to configure payment process proifle and for these two payment methods we don't have any option as 'Processing Type' as 'Wire' or 'Clearing', so what should be selected as prcossing type for 'Wire' and 'Clearing' payment method
4) We did not see payment method as 'Clearing' in R12 while creating AP invoices, even though this payment method is enabled in Payment Administrator...
Please suggest a way forward, eagerly waiting for your input and suggestion to configure the PPP for 'Wire' and 'Clearing' payment method.
Regards,
Raju.

Hi Raju,
I would say, the relationship between Payment Method and the Processing Type used in Payment process Profile is not on a ONE TO ONE basis, it is more like Many to One / One to Many relationship Type...ALSO THERE IS NO DEPENDANCY BETWEEN PAYMENT METHOD AND PROCESSING TYPE in PPP
The Processing type in the Payment process profile indicates how the Payment instruction is going to be processed, which is a background process/system configuration and not shared in front end.
The Payment method is an indication as to the available modes of payment shared in the Front end, it does not really have any processing related information ....(apart from seeded/user defined validations)
In Short any thing that is not printed would be electronic, hence Electronic, Wire and Clearing would all fall under Electronic processing Type.
1) What is the purpose and meaning of the column: 'Processing Type' at the PPP header level?
ANS - It means how the Payment Instruction would be processed.
2) Does it means that for 'Check' payment method we should choose only and only 'Printed' option and for 'Electronic' payment method we should select only and only 'Electronic' ,does this options is linked to these payment method?
ANS - NEED NOT BE ! I did a test case myself to get clarified, system would allow you to select a payment process profile of electronic type to a CHECK payment method ......It is totally up to the organization to decide how they want to process thier payment instruction, there is no dependancy on the payment method.... You could process a CHECK Payment electronically, you could process a WIRE payment in printed fashion as well ..
3) We have remaining two payment method: 'Wire' and 'Clearing' for which we need to configure payment process proifle and for these two payment methods we don't have any option as 'Processing Type' as 'Wire' or 'Clearing', so what should be selected as prcossing type for 'Wire' and 'Clearing' payment method
ANS - Select as Electronic for Wire and Clearing payment methods..
4) We did not see payment method as 'Clearing' in R12 while creating AP invoices, even though this payment method is enabled in Payment Administrator...
ANS - payment method was inactivated with the following explanation: "This is one of the seeded payment methods coming from AP, but it was decided to seed it as inactive so that it will not appear in LOVs automatically in release 12. This payment method is an odd work around to deal with inter-company payments prior to release 12 and its use should be discouraged in the new release." Customers can change the status to ACTIVE if they want to use this Payment Method. Inter-Company Payments
should be done using Oracle Treasury. Refer (ID 864855.1 - Why The Clearing Payment Method Is Inactive In R12?)
5) Additional point - when you create your payment process profile, there is a section called USAGE RULES, where you have a region for Payment Methods. You have to select the payment methods that can access this payment process profile, by default the value is selected as ALL ... if you do not want it to be available for all,you can select specific payment methods ... that is
1) Payment Process Profile of PRINTED processing Type should be available for CHECK payment method only
2) Payment Process Profile of ELECTRONIC processing Type should be available for WIRE, ELECTRONIC and CLEARING payment method only
This is a configurable control and not a system restriction / intended behaviour.
I am unable to find a clear oracle documentation to justify my view stated above, these are purely based on my experience on the application .. hence i would await others to express thier opinion and correct me if i am wrong ...
Honestly this is an excellent Question ......!

Ivruksha
