RFC experts : doubt

Hi,
I am using a frontend with multiple logon IDs to call an RFC with a single SAP user ID (for spool job creation).
Now ths issue is :
When a single front-end(non sap) user logs in and does the process of sales order/deliver creation/sapscript/pdf conversion/ftp to web server a single PDF document is obtained.
When two or more front-end users simultaneously hit the button for the process of sales order/deliver creation/sapscript/pdf conversion/ftp to web server, then the pfd get merged with the two or more documents.
The first process after hitting the button for the process of sales order creation is the call to an RFC.
Maybe there is a process to make the user 2 wait until user 1 has called RFC and the entire process is over. How can this be achieved in ABAP/4.
WAIT UP TO 10 SECONDS. will not work because effectively user A and B will be a few micro seconds away from each other. Is there any other process to delay the RFC call.The front-end call to RFC is supposed to be synchronous.
Any pointers to the solution.Thanks.

Hi SV,
This problem seems to be problem of locking. Lock the program for further access until a user has executed it. as you mentioned WAIT is not a good idea. Create a Lock Object and use the FM ENQUEUE and DEQUEUE, associated with it to achieve the functionality.
Thanks & Regards,
Goutham.

HTTP RFC scenario doubt

I have created http to RFC scenario in XI
Previously this interface was using Business Connector and following XML message was used.
<? xml version="1.0"?>
<TAC>
 u2026.
 u2026.
 u2026.
 u2026.
</TAC>
Based on it I have created data type and message type in XI and created interface and following is my incoming XML message.
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_TAC xmlns:ns0="urn://Website/CreateServiceOrder">
 <TAC>
 u2026.
 u2026.
 u2026.
 u2026.
 </TAC>
</ns0:MT_TAC>
So u201C<ns0:MT_TAC xmlns:ns0="urn://Website/CreateServiceOrder"> </ns0:MT_TAC> are the extra tags
Is it required to send these additional tags in the incoming XML Message?
I hope you have got the question.
Thanks,
Vishal

i think these are the start and end tags of the MT in IR.....so if i remove them wont i get an error??....how will the incoming payload go into the MT if the structure is different??
What can be done is create the DT/MT with TAC as name and not MT_TAC.....make a note that it is not according to the naming convention....

Hi experts doubt in dictionery

what is lock object, types of lock objects, how we can create lock object could you please send steps for creation.
what is match code object and search help types of search helps how we can create could please send steps.

Hi,
How many types of lock objects?
How to create Lock objects?
What is the main use of it in real time?
Lock objects are use in SAP to avoid the inconsistancy at the time of data is being insert/change into database.
SAP Provide three type of Lock objects.
- Read Lock(Shared Locked)
 protects read access to an object. The read lock allows other transactions read access but not write access to
 the locked area of the table
- Write Lock(exclusive lock)
 protects write access to an object. The write lock allows other transactions neither read nor write access to
 the locked area of the table.
- Enhanced write lock (exclusive lock without cumulating)
works like a write lock except that the enhanced write lock also protects from further accesses from the
same transaction.
You can create a lock on a object of SAP thorugh transaction SE11 and enter any meaningful name start with EZ Example EZTEST_LOCK.
Use: you can see in almost all transaction when you are open an object in Change mode SAP could not allow to any other user to open the same object in change mode.
Example: in HR when we are enter a personal number in master data maintainance screen SAP can't allow to any other user to use same personal number for changes.
Technicaly:
When you create a lock object System automatically creat two function module.
1. ENQUEUE_<Lockobject name>. to insert the object in a queue.
2. DEQUEUE_<Lockobject name>. To remove the object is being queued through above FM.
You have to use these function module in your program.

HI
What are the steps to create a dynamic ALV ? can some one help me out.

Its very simple if you understand .
make these declarations
DATA: L_STRUCTURE TYPE REF TO DATA,
 L_TABLE TYPE REF TO DATA,
 STRUC_DESC TYPE REF TO CL_ABAP_STRUCTDESCR,
 LS_LVC_FIELDCATALOGUE TYPE LVC_S_FCAT,
 LT_LVC_FIELDCATALOGUE TYPE LVC_T_FCAT.
FIELD-SYMBOLS :
<IT_TABLE> TYPE STANDARD TABLE,
<DYN_STR> TYPE ANY,
<STR_COMP> TYPE ABAP_COMPDESCR.
Then we create the structure dynamically,
Syntax:
Dynamic creation of a structure
CREATE DATA L_STRUCTURE TYPE (P_TABLE).
ASSIGN L_STRUCTURE->* TO <DYN_STR>.* Fields Structure
STRUC_DESC ?= CL_ABAP_TYPEDESCR=>DESCRIBE_BY_DATA( <DYN_STR> ).
We build the fieldcatalog by looping the structure :
LOOP AT STRUC_DESC->COMPONENTS ASSIGNING <STR_COMP>.
Build Fieldcatalog
 LS_LVC_FIELDCATALOGUE-FIELDNAME = <STR_COMP>-NAME.
 LS_LVC_FIELDCATALOGUE-REF_TABLE = P_TABLE.
 APPEND LS_LVC_FIELDCATALOGUE TO LT_LVC_FIELDCATALOGUE.
Build Fieldcatalog
 LS_FIELDCATALOGUE-FIELDNAME = <STR_COMP>-NAME.
 LS_FIELDCATALOGUE-REF_TABNAME = P_TABLE.
 APPEND LS_FIELDCATALOGUE TO LT_FIELDCATALOGUE.
ENDLOOP.
Then we create the dynamic internal table:
CALL METHOD CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE
 EXPORTING
 IT_FIELDCATALOG = LT_LVC_FIELDCATALOGUE
 IMPORTING
 EP_TABLE = L_TABLE. ASSIGN L_TABLE->* TO <IT_TABLE>.
Then its a dynamic select if required we can Use. rest is the same process.
i will give you a link again

Hi experts doubt real time environment

hi abapers could u please guide me

produaction no         :

Hi Sayeed,
User ID: It is ID created by the system administrator.Genarlly they follow some
             standard for this.My company follow it as Last name + first Character
             of Name So,I become RAJANN
System ID: This is system id again assigned by Basis team(system people).Generally,it denotes the system number in whole landscape if you have same kind of instance.Suppose you have three same kind of system ,you can put it as 01,02,03 etc.
Request Number: This is a request number assigned for making any changes in system.It is just like a number using which you can track the changes made in system in terms of development or any configurational changes.These number are transported from one system to another system.
SAP ask to apply atleast three environement.
DEV-Development system where all changes are done and you create transport request here in terms of development & Configuration.
QAC:Transport are moved into QAC system.In QAC system you do testing of the object and do quality check.
PRD-Production system is one where all transaction and other activity of enterprise happen .
So a transport request move changes from DEV->QAC->PRD using request number.
Quality server number: This is just like IP address ,a number assigned to your system,it is like address of your system in entire network landscape.For understanding purpose you can assume this system as simple computer and all computer have some IP address so Quality server number will also have some IP address and this refer exactly that.
Production System: It is exactly as explianed above.

Idoc - XI - RFC

Dear ll
i developing a scenario in Pi
i.e IDOC - XI - RFC
my doubt is , when i am creating the Interface determination , we have to specify the Interface mapping r Not . If S y. because i am not created any MT for My scenario.becasue i am using std Idoc & RFC which i know already
in the Interface determination , i am directly put a a inbound interface as my RFC name . When i try to Put IM . Its disabled , Not able to Put.even i have a Message interface (1 for inbound & another is for outbound) .
my doubt is is it really required a IM in Interface determination ..

Hi Irfan,
You don't need to create any DT,MT or MI for RFC and IDocs. But still you need to define a mapping (between IDoc and RFC)
and which should be incorporated in the Interface mapping. have you provided the correct sap standard namespaces for IDoc and rfc while creating your interface determination?
While createin the Interface determination have dragged the indbound and outbound interface as IDOc / RFC ?
please check this hope it should resolve the issue.
Thanks

RFC Sender problem between 46D and RFC adapter

Hi,
I have this simple integration scenario where I want to send data to a archiving system;
SAP -> (tRFC) -> XI -> (MQ) -> BizTalk -> (MQ) Arch.syst.
SAP side ***
A Z-program using a Z func. like;
 CALL FUNCTION 'ZSD_DCF_SEND_TAG'
 IN BACKGROUND TASK
 DESTINATION 'XISYSTEM_TRFC_DCF'
 EXPORTING
 pt_filing_info = gt_filing.
 COMMIT WORK AND WAIT.
XI side ***
Both IR and ID is configured correctly, in the development environment everything works just great. I have created a test program where I can define how many calls I will do, looping over the func. call with a commit inside the loop - 500 or more msgs are ok.
The integration scenario is transported to quality enviroment using CMS, and the RFC sender comm.ch. is configured accordingly.
The problem in quality ***
When sending just 1 msg, everything is just fine, message received and delivered to MQ.
When sending >= 2 msgs, the 1 msg is always ok, BUT all others fails due to the following from Adapter monitor;
RFC_HISTORY
- Error: 2006-01-19 10:55:18 CET: com.sap.aii.af.rfc.afcommunication.RfcAFWException: lookup of alternativeServiceIdentifier via CPA-cache failed for channel 'RFCSender_XI0002' (02d4d30de3593874942ed0659add0827, party '', schema 'TechnicalSystem', identifier 'Q93#120')
- OK: 2006-01-19 10:55:17 CET: Message processed for interface ZSD_DCF_SEND_TAG
My sending system is Q93 CLI 505 so I can understand the error, BUT I cannot understand why the RFC adapter is saying the TechnicalSystem is Q93#120 - it should be Q93#505. My Q XI has client 120...
It seems to me that the RFC adapter is kind of confused about the sender..
I have created a OSS message and SAP has looged on and looked into it with both a XI expert and RFC expert without being able to answer - all is configured correctly.
- The SLD config. for bus.system Q93 is ok -
- The bus.system in ID is showing correct vaues for
Adapter Specific Identifiers (SID Q93, client 505)
- Both Dev. and Qual. environment are running on XI 3.0 SP 14 latest patch, RFC component version on the SAP side is identical between dev. and qual. SAP systems
- It doesn't matter which gw I use (Q93 gw or XI gw), the error is persistent
- It doesn't matter if I increase initial conn, max conn.
I have also tried to use qRFC instead, but with the same result.
Anyone using tRFC for asynch. communication from SAP to XI seeing something similar?
Meanwhile, I will do RFC trace on GW and RFC Adapter on AE....
Please, do not say SP15, oss msg for FAQ RFC adapter or links to RFCAdapter config....
best regards
Torstein

Hi,
SAP Note 730870 FAQ: XI 3.0 RfcAdapter Q.no 15
Q 15: Whats wrong when the error message "lookup of alternativeServiceIdentifier via CPA-cache failed" shows up while sending a RFC call to the RfcAdapter?
A: A RFC sender channel is located beneath a service within the Integration Directory. Within this service choose "Service" -> "Adapter-Specific Identifiers". The values in the fields "R/3 System ID" and "Client" has to be maintained with the correct values of the system, that sends the RFC call to the RfcAdapter. It normaly only makes sense to have these values filled for services of type "Business System". If maintained in SLD, this fields will be filled automaticaly for services of type "Business System" and can be updated with the button "Compare with System Landscape Directory".
- Give correct appserver and gateway service details in XI.
- Open the service holding the RFC adapter you are trying to use. On the top menu, goto Service -> Adapter Specific Identifiers..

Challenging issue with JDBC sender adapter

Hello Guys
I have this requirement
From Oracle Database I have to read to tables one for the header and one for the detailes and map the result to one RFC.
I have only worked with one table at the time with the JDBC sender adapter but never with 2 tables
My challenges are
1 - How I can read the 2 tables at the same select statement , I suppose I have to use a join with 2 identical fields , so far so good ,but how I can handle multiple records
suppose the result is 10 new different records which each of the recored has to be mapped to the RFC , then we will have 10 RFC calls.
how can I do the mapping in this case.
2 - How can I update the 2 tables at the samme time and flag them as processed , as far as I know we can not use 2 update statement in the same JDBC sender
any help will do
Thanks in advance.

Hi
Thanks for the replayes
The RFC is used to create and Invoice Idoc , It has to be one record (Header and Item ) to one RFC.
a JDBC to IDoc can also be used , but we have to update another table in SAP that is why the RFC,
My doubt is how the Data type for the sender JDBC should look like , as mentioned I have 2 tables to fetch data from
<Invoice>
<Header> 1 -- 1
<f1>
<f2>
<f3>
</Header>
<Item> 1--n
<f1>
<f2>
<f3>
</Item>
</Invoice>
The sender JDBC returns
<Invoice>
<row>
<f1>
<f2>
<f3>
</row>
</Invoice>
How can I replicate the data type to meet the JDBC sender structure.
and regarding the mapping do I have to change the occurrunce to 0 -- unbounded
regarding the update Ragu is right in his suggestion
Table1 can be used as primary table, Table2 can be used as Secondary table.. u will have key field to link both table.
So Just Updating only Primary Table(Table1) will helps on this.
Thanks.

ORA-00936 not being returned.

I by accident ran across a syntactical error that SQL Developer is not reporting. Run this select query is both SQL Plus and SQL Developer....
select table_name, upper(substr(table_name,1,instr(table_name,'\')- 1)),
upper(substr(table_name, instr(table_name,'\') ,444)),
from all_tables;
Notice that SQL-Plus will return "ORA-00936: missing expression" because there is an extra comma just before "from all_tables". However, SQL Developer does not do this properly and states "All rows fetched: 0".
My versions...
SQL Developer 1.5.4
Oracle 10.2.0.4

Srinivas,
Yes, yes, and yes
A little more background... we're attempting to move the process to a new SAP box which uses AIX. The SAP RFC toolkit was installed and the C program was compiled successfully. The only things changed were the directories where the program resides.
I think you're correct in saying something in the code probably does not work properly with AIX, but I was hoping for hints as to what it might be (since it compiled in AIX).
...guess I need to track down a C/AIX/RFC expert...
Rob,
I double-checked, no short dumps are occurring. The RFC appears successful, but the data is not returned.
Thanks again.

PI' RFC Connection pool doubt.

Hi PI exports:
i have a doubt about pi' RFC Connection pool ,pi RFC receive channel can set the conn pool size ,but when start the rfc receiver channel ,is there always only one Connection pool ,or there is only one Connection pool instance?
thinks
Edited by: kevin liang on Oct 19, 2009 6:45 AM

Hi,
Connection poolins size means how many number of connection you want to make open to send data to ECC, We can define maximum number of connection in Receiver RFC Adapter,Go to additional parameters section and define Max Number of connection give the number there,thats it.Internally it works as Connection poolin mechanism.

Doubt regarding Sender adapter file content conversion to RFC

Hi Experts,
Below is the my Source and Target XML structure ( i have creaated source structure same as target RFC structure), This scenario is working fine when i give XML file as input. File -> XI -> RFC , xml file is able to update the information in R3.
How should i configure sender file adapter for file content conversion for above structure(in this case input is fixed lenth text), and i could able to change source structure according to our req, without changing target RFC strucuture.
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_HSA_IDNumber xmlns:ns0="urn:passhe.com/UpdateIdNumberISA32">
 <COMMIT_I>X</COMMIT_I>

 <VALID_FROM>20070421</VALID_FROM>
 <VALID_TO>20091231</VALID_TO>
 </IDENTIFICATION>
</ns0:MT_HSA_IDNumber>
I have configured sender file adapter with FCC like :
Document name as: MT_HSA_IDNumber
Document name space as: urn:passhe.com/UpdateIdNumberISA32
Record structure as: COMMIT_I,1,IDENTIFICATION,1
COMMIT_I.fieldNames : COMMIT_I
COMMIT_I.fieldFixedlengths: 1
IDENTIFICATION.fieldNames: STUDENT,ID_TYPE,ID_NUMBER,VALID_FROM,VALID_TO
IDENTIFICATION.fieldFixedlengths: 12,6,60,8,8
i am getting error like this: even when i change source structure like below metioned:
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_HSA_IDNumber xmlns:ns0="urn:passhe.com/UpdateIdNumberISA32">
 <COMMIT>
 <COMMIT_I>X</COMMIT_I>

Please help me out
thanks
dhanush

Hi Dhanush,
Try giving the Sender FCC this way for the source structure you have mentioned above.
Record structure as: COMMIT,1,IDENTIFICATION,1
COMMIT.fieldNames : COMMIT_I
COMMIT.fieldFixedlengths: 1
Hope this helps.
Thanks and Regards,

Doubt Regarding Sender Rfc adapter calls

Hi Experts,
When we call RFC in R3 system by giving destination as XI system,
1) where exaxtly RFC cal executes either in R3 or XI?
In case of sender RFC syncronouse call? where exaxtly RFC cal executes either in R3 or XI?
In case of sender RFC asyncronse call? where exaxtly RFC cal executes either in R3 or XI?
2) In case of Recever RFC syncronouse call, where exactly RFC call executes, is it in XI or R3 system?
Please help me out.
thanks
siva

1) where exaxtly RFC cal executes either in R3 or XI? 
It is at R3 for bothe sync and asyn sender scenario.
2) In case of Recever RFC syncronouse call, where exactly RFC call executes, is it in XI or R3 system?
RFC is called from XI. The call is actually executed at R3 receiver

Doubt regarding File Content Conversion. File- RFC

Hi Experts,
My scenario is File -> XI -> RFC,
I am able to update the records in R3 when i get a fixed length file with a single record.
RFC can process one record at a time (its 1 to 1 , its not 1 to unbounded),
May i know what are the changes to be done in the scenario to implement this existing interface to process a fixed length file contains a multiple records.
How to get RFC return messages when ever there is return message , as this is not the synchronous scenario.
Please help me out.
Thanks

HI,
First you need to create a structure [SE12]
Once that is done, open the function module [SE37] and select the tab [Table].
Add a new parameter and for the Associated Type use the structure that you have just created.
Then reimport the RFC in XI.
I hope it helps.
Now, to make the RFC return messages you shall create a BPM.
Notice that this will be a Async -> Sync -> Async interface...
Basically your bpm steps will be like this:
Receive,
Transform if needed,
Syncronously Send and receive response,
Transform again if needed,
Send Asynchronously.
Take a look at the image in the link to have a better idea on the BPM setup

Doubt on FILE to RFC & PROXYS

Hi everybody,
 I'm able to solve most of my doubts by this forum, thankz to everybody who assisted me.Here are some simple doubts plz give solutions to them as many as possible
 1.In my FILE to RFC scenario I'm using BPM & i should send response back to SENDER so what steps should i include in it ? I'm using BAPI_GOODS_MVT_CREATE bapi?
 2.In my FILE to RFC scenario I'm maintaining single SLD for DEV,CONS,PROD ,so can i configure my file sender service directly in ID as a BUSSINESS SERVICE?
 3.Can any one give some information In which case we have to go for
PROXY & in which case for IDOC?exluding this reason " if syst config is >6.20 or else go for IDOC or RFC for an sap system?
 Plz kindly answer to this questions & valuable answers are rewarded.
 Regards,
 Vinod.

1.In my FILE to RFC scenario I'm using BPM & i should send response back to SENDER so what steps should i include in it ? I'm using BAPI_GOODS_MVT_CREATE bapi?
>>>
Ref: /people/arpit.seth/blog/2005/06/27/rfc-scenario-using-bpm--starter-kit
Else in case you have SP19 then ref this abstract from an earlier post !!
All,
Just thought I'd add a quick note here.
From SP 19 on XI 3.0 and SP 10 on PI 7.0, a File - RFC - File ( Asynch - Synch ) scenario can be done without a BPM.
Steps:
Integration Repository
The Integration Repository will be similar to any Synchronous Scenario ( say HTTP - RFC ) . 1 Outbound Synch message Interface and 1 Inbound Synch Message Interface.
Integration Directory
This is where a few differences lie, so let me take some time.
1. The Receiver Determination , Interface Determination will be the same as in HTTP - RFC synch scenario. Create the Sender File Adapter, Receiver RFC Adapter and Receiver File Adapter.
2. Sender Agreement will be for the Sender File Adapter. Sender Agreement uses the Synch Outbound Message Interface.
3. Receiver Agreement will be for the Receiver RFC adapter. Receievr Agreement will use the RFC as thge Inbound Message Interface.
4. We need to add a few modules in the Sender File Adapter.
Go to the Modules Tab of the Sender File Adater, and add the following modules in the same sequence,
Number - ModuleName - Type - ModuleKey
1- AF_Modules/RequestResponseBean - Local Enterprise Bean - 1
2- CallSapAdapter-Local Enterprise Bean - 2
3-AF_Modules/ResponseOnewayBean-3
Parameters
ModuleKey - ParameterName - ParameterValue
1 - passThrough - true
3-receiverChannel - Receiver File Adapter Name
3-receiverService - Receiver Business Service/ System
With this configuration, you can now handle the requirement without a BPM
This feature been already blogged for JMS Adapters in these blogs ,
Sync/Async communication in JMS adapter without BPM (SP19)
Async/Sync Communication using JMS adapter without BPM (SP 19)
Dynamic Configuration is also possible,and this as well as many other options are discussed in the How To guide - "How To Realize a sync-async and async-sync
bridge within the Adapter Framework" available on the Service Market Place.

In my FILE to RFC scenario I'm maintaining single SLD for DEV,CONS,PROD ,so can i configure my file sender service directly in ID as a BUSSINESS SERVICE?
>>
you can use Business service !!!
