Where we use ale in bussiness scenario?

Hi everybody
where we use ale in bussiness scenario?
y Im asking this is we can communicate with bapi also!
so we shud we go for ale?
points will be given!
Mr.Reddy

HI
the functionality of both idoc and bapi are same.
the main difference in BAPI is it is used for Third party application like JAVA, VB etc.
and IDOC is used transfer data from the SAP to sap or non-sap system.
For details refer the contents below
ALE
ALE is SAP proprietary technology that enables data communications between two or more SAP R/3 systems and/or R/3 and external systems. When a new enterprise resource planning (ERP) solution such as R/3 is implemented, companies have to interface the ERP system with legacy systems or other ERP systems.
ALE provides intelligent mechanisms where by clients can achieve integration as well as distribution of applications and data.
ALE technology facilitates rapid application prototyping and application interface development, thus reducing implementation time.
The ALE components are inherently integrated with SAP applications and are robust, leading to a highly reliable system.
ALE comes with application distribution/integration scenarios as well as a set of tools,
programs, data definitions, and methodologies that you can easily configure to get an interface up and running.
BAPI
BAPIs provide a stable, standardized method for third-party applications
and components to integrate into the Business Framework.
These interfaces are being specified as part of SAP's initiative with customers,
partners and leading standards organizations.
Also, SAP has implemented the emerging Object Application Group (OAG) specifications with BAPIs.

Using ale u can send from sap to sap and sap to non sap systems

hi,
using ale u can send from sap to sap and sap to non sap systems,
then what is diff b/w ALE and EDI

Hello KALYAN KUMAR,
Application Link Enabling (ALE)
1.You distribute data using ALE if you want to communicate from one system to one or more other (mostly internal) systems.
2.ALE transfers data in IDoc format and uses the methods of tRFC for data transfer.
3.ALE enables the integration of business processes across several SAP or non-SAP systems.
Electronic Data Interchange (EDI)
1.You use EDI if you want to exchange business application documents with an (external) partner system (for example, a customer or vendor).
2. The SAP system sends EDI messages in IDoc format to an EDI subsystem, where they are converted to a universal EDI standard (UN/EDIFACT or ANSI/X12).
3. This enables communication with non-SAP systems.
By definition, two partners are involved in the process in an EDI application scenario: The sender and the recipient of an EDI message
I hope u understands the difference:)

Data transfer using ALE/IDOC into XML.

Dear All,
I have to transfer FI document data (FB01) from the sap system ,convert it into XML and dump it in 1 of the file servers.I want to do this using ALE/IDOC.Is it possible to do the same and how.Similarly i want to do the same for Vendor and Customer master i.e sending the data in XML format.
Kindly Suggest how do i go about doin the same..Its very urgent.Please help.
Thanks & Regards,
Lailu Philip.

In continuation:
Example Purchasing & Selling scenario
We will develop a custom IDoc to carry the billing number from the Service Receivers system to the Service Providers system. We will populate the IDoc in a user exit on the sending side and we will process the transaction on the receiving side using a custom function module and a BDC transaction call.
No rule conversion, segment filtering or version conversion will be implemented in the model as described in Figure 1.
Requirements
Working ALE environment - See ALE Basis Configuration Guide;
ALE scenario design together with the business requirement;
Development access; and
ALE configuration access.
NOTES:
1. All IMG references to transactions are located in the transaction SALE which is the ALE portion of the IMG
2. This is one way of developing a scenario where no message control exists. If message control exist (EG. On purchase orders) then NAST can be used to call an outbound function module that would create the required IDocs.
3. Extensive knowledge of IDocs and ALE basis configuration is required in order to understand this guide.
2. OUTBOUND PROCESSING
2.1. Create IDoc type (WE30) Client independent
The IDoc type refers to the IDoc structure that you will require for your development. In our case the IDoc type is called ZINVRV01. This IDoc type will have 1 segment called Z1INVRV with 2 fields, LIFNR & XBLNR, in this segment. If you require many segments or nested segments then they are also created using the same procedure.
We will create the IDoc of the following structure:
ZINVRV01
Purchasing and Selling - Invoice receipt reversal
Z1INVRV P&S - Segment 1
Segment fields
LIFNR Vendor account number
XBLNR Reference document number
Figure 3: IDoc type ZINVRV01
To create the IDoc type, follow these next few steps:
Enter transaction WE30 (ALE -> Extensions -> IDoc types -> Maintain IDoc type)
Type in ZINVRV01 and click on Basic IDoc type, click the Create icon
Click on Create new (we are creating an IDoc from scratch but you may want to copy another IDoc if it is similar to your requirements) and enter a description, and press enter
Click on ZINVRV01 and then on the Create icon
Enter Z1INVRV as the segment type (must start with Z1), check mandatory if the segment must exist (in this case check it), enter 1 in minimum number and 1 as maximum number. (Make the maximum number 9999999999 if there are going to be many of these segments in each IDoc. IE. When line items are passed via IDocs), click on Segment editor
Enter a description for your segment type and create
Enter a description for your segment, enter each field required in your IDoc, in our case type LIFNR across for Field name, DE structure and DE documentation, repeat for XBLNR and press enter to validate.
Save and generate, press back
To release the segment choose Goto, Release from the menu
Check the box on the line of your new segment
Save, back and enter
Your IDoc type structure should be displayed with your new segment
Save and back
To release the IDoc type choose Extras, Release type from the menu and Yes
Your IDoc is now ready for use. If you need to add fields or segments to your IDoc type, you will need to cancel the release of the IDoc type as well as the segment release using a similar procedure followed above (except now you uncheck the release box for the segment and you choose cancel release for the IDoc type).
2.2. Create message type (WE81) Client independent
To create a new message type, follow these next few steps:
Enter transaction WE81 (ALE -> Extensions -> IDoc types -> Maintain message type for intermed. Structure -> Create logical message type)
Choose Create logical message type by double clicking on it
Click on change icon to enter change mode
Click on New entries to add a new type
Enter the required message type, in our case it is ZINVRV and an appropriate description
Save and exit.
Your message type has now been created. The next step will be to link it to the IDoc.
2.2.1. Link message to IDoc type (WE82 & BD69) Client independent
To link the message type to the IDoc type follow these next few steps:
Enter transaction WE82 (ALE -> Extensions -> IDoc types -> Maintain message type for intermed. Structure -> EDI: Message Types and Assignment to IDoc Types)
Click on change icon to enter change mode
Click on New entries to create the link
Enter the message type ZINVRV and the BasicIDoc type as ZINVRV01
Save and exit
Enter transaction BD69 (ALE -> Extensions -> IDoc types -> Maintain message type for intermed. Structure -> Assign message type to IDoc for ALE)
Click on change icon to enter change mode
Click on New entries to create the link
Enter the message type ZINVRV and the BasicIDoc type as ZINVRV01
Save and exit
Your IDoc is now linked to your message type. We still need to link object types and add the message to the model before we can use the message.
2.2.2. Maintain object type for message type (BD59) Client independent
The ALE objects are used to create links between IDocs and applications objects, to control the serialisation, to filter messages in the customer model and to use listings.
For our own message type and IDoc you must maintain object types for the links.
If you want to check the serialisation for the message type, then you must maintain object types for the serialisation. If no serialisation object has been maintained for a given message type, then the serialisation will not be checked for this message type.
To add an object type to our message type, follow these next few steps:
Enter transaction BD59 (ALE -> Extensions -> ALE object maintenance -> Maintain object types)
Type in your message type ZINVRV and press enter
Click on New entries
Enter your object type, LIFNR (We need to use the vendor as a filter object), the segment name where LIFNR resides, Z1INVRV, a number 1 for the sequence followed by the actual field name LIFNR
Save and exit.
You have now created an object that well use as a filter object in the customer model to direct the flow of messages to the various logical systems based on the vendors in the filter of the message type ZINVRV.
We now need to add our new message type to the distribution model.
2.3. Configuring the Distribution Model
This task is performed on your ALE reference client.
2.3.1. Manual Configuration (BD64) Client dependent
To manually configure the customer distribution model, read the ALE configuration procedure, and follow these steps:
Perform the Maintain customer distribution model directly function. (ALE -> Distribution customer model -> Maintain customer distribution model directly)
Specify the customer model you want to maintain and the logical system that is to be the sender of the messages OR create a new model. (Create model ALE with logical system ALELS1C400)
Choose the receiving systems to which the sending system must forward message type ZINVRV to.
For each receiving logical system allocate the message type necessary for communication to the receiving systems as per ALE configuration procedure.
Create filter objects (in our case LIFNR as the object type with the associated vendor number, 0000018001 with leading zeros, in the object area) for the message types.
Save the entries.
NOTES:
You cannot maintain a message type between the same sender and receiver in more than one customer distribution model.
Only the owner is authorised to modify the model.
To change the owner of a model, choose the 'Maintain ownership of customer distribution model' function. Make sure that all changes will be distributed to all systems that know the corresponding model. To do so, you can use the correction and transport system.
To transport the customer distribution model you should use the Distribute customer model function of the IMG as described below.
2.3.2. Distribute customer model (BD71) Client dependent
After the customer model has been created centrally, it must be distributed to the other remote systems. This entails first of all setting up the communication for the distributed systems and then sending the model.
2.3.2.1. Distribute Model (BD71) Client dependent
This task is performed on your ALE reference client. To distribute the customer distribution model, read the ALE configuration procedure and follow these steps:
Make the settings for the communication with the other decentral systems, you have not set them yet.
Define the RFC destination for R/3 connections whose names correspond to the name of the corresponding logical system.
Create the output partner profile.
Distribute the customer model
Specify the name of the customer model.
You must specify the target system to which you want to distribute the customer model.
You must repeat this function for every distributed logical system.
2.3.2.2. Maintain sending system partner profile (WE20) Client dependent
With this function, you define the partner profiles for all outbound and inbound messages on the basis of the customer distribution model.
After you have defined and distributed the customer model, you will have to maintain the partner profiles locally. To do this read the ALE configuration procedure.
Enter the output mode (background, immediately) and the package size for outbound processing.
Requirements
The customer model must be maintained.
RFC destinations must be maintained.
The customer model must be distributed.
To ensure that the appropriate persons in charge are informed if a processing error occurs, you must make settings in: Error processing Maintain organisational units.
2.4. Populate & distribute IDoc using ABAP
An IDoc consists of a control record with structure edidc and one or more data records with structure edidd. The control record contains the sender and recipient of the IDoc, as well as information on the type of message.
To be able to pass an IDoc to the ALE layer, you must set up a field string with structure edidc and an internal table with structure edidd. They are used to call function module master_idoc_distribute, which performs the save to the database and triggers the dispatch if necessary.
2.4.1. Example code
The code displayed below does the following:
populates our IDoc segment Z1INVR with the 2 fields XBLNR and LIFNR, populates the segment name and appends this to an internal table used to store the IDoc data;
populates the control record info with the message type and IDoc type; and
calls the MASTER_IDOC_DISTRIBUTE function module which distributes the IDoc as configured in the customer distribution model.

Figure 5: Inbound processing example code
3.1.1. Debugging inbound FM
Use transaction WE19 to test inbound function module in debugging mode. Also use WE05 to view the IDocs and their statuses.
3.2. Maintain ALE attributes
The inbound function module needs to be linked to the message type and the message type needs to be linked to the appropriate inbound process code at the partner profile level before the scenario is enabled. These steps are described below in detail.
3.2.1. Link Message Type to Function Module (WE57) Client independent
To link a message (ZINVRV) type to a function module (Z_IDOC_INPUT_ZINVRV) follow these steps:
Enter transaction WE57 (ALE -> Extensions -> Inbound -> Allocate function module to logical message)
Select an entry (EG. IDOC_INPUT_ORDERS) and copy
Type in module name Z_IDOC_INPUT_ZINVRV
Type in basic IDoc type as ZINVRV01
Type in message type as ZINVRV
Type object type as IDOCINVOIC (Invoice document) - Used for workflow
Direction should be set to 2 for inbound
Enter and save
3.2.2. Define FM settings (BD51) Client independent
Enter transaction BD51 (ALE -> Extensions -> Inbound -> Define settings for input modules)
Click on New entries
Type in the name of the new function module Z_IDOC_INPUT_ZINVRV
Enter 0 for mass processing in the output column
Save and Exit
3.2.3. Maintain process codes (WE42) Client dependent
A process code needs to be maintained on each client. It then needs to be linked to the message via the partner profiles on each client. This allows the various clients to use a unique function module for the same message type.
To maintain the process code follow these steps:
Log on to the appropriate receiving system client
Execute WE42 (ALE -> Extensions -> Inbound -> Maintaining process codes inbound)
Choose Inbound with ALE service
Choose Processing with function module
Click on Processing with function module and choose create icon
Click on New Entries
Type in process code ZINR and give it a description and save
Now you are asked to Please maintain codes added in ALE entry methods, enter and choose Z_IDOC_INPUT_FIRVSL and copy it. You should choose a FM similar to your one.
Enter your process code ZINR
Enter your function module Z_IDOC_INPUT_ZINVRV
NOTE: The next 6 steps are used in workflow error handling.
Enter IDPKFIDCMT in object type
Enter MASSINPUTFINISHED in End event
Enter IDOCINVOIC in IDoc object type
Enter INPUTERROROCCURREDFI in IDoc start event
Enter INPUTFINISHEDFI in IDoc End event
Enter IDOCINVOIC in Application object type
You will need to determine the task associated with object IDOCINVOIC, and then assign the appropriate position to it. This position will then receive the application error messages via workflow.
To set up the workflow area please consult the Workflow config guide.
3.3. Create inbound partner profile
For each message type you need to maintain the inbound partner profiles.
3.3.1. Maintain receiving system partner profile (WE20) Client dependent
To maintain inbound partner profiles read the document ALE configuration procedure:
Add the message type ZINVRV with process code ZINR.
Enter the output mode (background, immediately) for inbound processing and NO message code.
Enter the position S and choose the ALE administrator 50000085. This position will then receive all the technical ALE errors via workflow.
3.4. Test
Once the inbound function module has been debugged the scenario should be ready to test in its entirety. If problems occur, read through the relevant areas of this document to check your configuration or code.
Hope this will help you,
If you want me to explain more, you can give me your email id.
Reward with points incase you are satisfied.

Explain the situation for using ale , bapi ,session ,call transation, di

what is the use of bdcmsgcall,
if any erroe occur in the legacy records how to rectify it?
In what situation we can go for lsmw.
Kindly explain the situation's for using ale , bapi ,session ,call transation, direct input.

Hi ashok,
chk this.
the functionality of both idoc and bapi are same.
the main difference in BAPI is it is used for Third party application like JAVA, VB etc.
and IDOC is used transfer data from the SAP to sap or non-sap system.
For details refer the contents below

Session method.
1) synchronous processing.
2) can tranfer large amount of data.
3) processing is slower.
4) error log is created
5) data is not updated until session is processed.
Call transaction.
1) asynchronous processing
2) can transfer small amount of data
3) processing is faster.
4) errors need to be handled explicitly
5) data is updated automatically
Session method is to populate the data by filling BDC structure
and keep as session to process from SM37 to post in appropriate Transaction.
Call transaction method is to post the data directly into the Transaction from an Executable program.
Session method SAP defined Function modules.
U can see more help on the differences in the SAP help.
hope u got an idea.

Bussiness Scenario for GENERIC EXTRACTION

Hi friends,
 can any one explain me... in what situation we go for Generic Extractions..
The normal reason is When the Bussiness Content Datasource is not matching with our requirement.. we go for Generic extraction..
 I told like this only... but they are not satisfied with my answer.. and they asked .. tell me the bussiness scenario( in what situation u done generic extraction)
so, friends... could any one plz explain me any scenario... which you done for generic extraction...
 i will appriciate by giving points to the appropriate answers..
Thanks

2)Double click on the Extract structure.
3)Now click on the append structure button to add the required field on to the existing structure.
4) add your required fields with ZZ appended to your field.
5) Save & Activate the append structure. Then go back and make sure you activate the extract structure also.
6) Now again go back to RSA6 and select your Data Source. But this time go to change Data Source to remove the hide option to the enhanced fields. By default theyll be in hide mode. If you dont remove the hide field then this field will not be seen in BW side.
7) Now go to SE38 to write the logic to populate the data into the enhanced field. Program name to write the logic is ZXRSAU01.
8) Check + Save + Activate.
9) Check in RSA3 if data is populated as per your requirement.
10) Replicate your Data Source.

ALE Inbound FILE scenario

Hi
we are running 46c and want to hear if it possible to set up a ALE FILE inbound scenario to SAP?
So what we want is to place IDOC's in a folder where SAP ALE then picks these files up and processes them.
Is it possible? What steps is needed to achieve it?
We see in WE21 that we have an file INBOUND possibility but how to use that in WE20 INBOUND for lets say a LS?
Hope somebody can help
Cheers

You can use program RSEINB00 and a file port. As for the other ALE config steps, you can find those in the help docs or by searching on the program name which will bring up multiple threads/links covering the topic.

Salesorder Creation Using ALE

Hi,
I am a new to the ALE scenario.
In the current project, whenever a Purchase Order is created, a coresspponding sales order is automatically generated using ALE. My questions are:
1) Is an Idoc generated in this scenario to create the sales order?
2) If yes, then from where can I get the message type, idoc type and the function module used, if the Idoc has already been archived.
3) If the salesorder is created without an Idoc (in this ALE scenario) then how can I find out which program is being used to create the sales order.
Any help would be greatly appreciated.
Thanks in advance.

Issue in Data transfers using ALE for E-Recruiting standalone system

Dear Experts,
We have an issue in data transfers using ALE. We are having standalone system where E-Recruiting is maintaind seperately and the version is EHP5.
When we configured iDoc in Sandbox and its working fine. But when it comes to Dev and Quality servers this is not working fine.
we have created iDocs using the following filters.
For Object P: Infotypes 0000, 0001, 0002, 0003, 0006, 0024, 0105.
For Objects O,S: 1032, Subtype: 0010
For Object: 1001, Subtype: A003, A008, A012, B007
For Object O: 1001, Subtype: A002, B002, B003, B012, Tyoe of related object: O,S
For Objects: C, O, S, Subtype: 1000, 1002, 1028
For Object:C, Subtype: 1001, Subtype: A007
When we do the data transfers in Sandbox using PFAL it is transferring the data properly.
But when we do the same iin Dev and Quality servers we are not able to do it and gettign 52, 51 errors.
Here we are facing a strange issue. For some Users when we transfer data it is transferring data but with 52 error messgae.
For some users I am getting 51 error where i could not transfer any data.
For some users, when we tranfer O, S, and P related data is moving but getting mostly 52 error and all the relationships are not moving here for O,S and properly. But P related CP, BP and NA are getting created successfully.
It is happening only in Dev and Quality server and that too some users are able to get transferred but not all.
Where will be the issue? How can we resolve this?
Any help will be appreciable.
Thank you in advance.

Creating Sales Order using ALE/RFC

Hi Friends
I required to do data transfer process in my implementation using ALE/IDOC. Since this is my first step in ALE/IDOC, I need help from an expert to start on.
1st scenario is using ALE in same client & same sap system.
2nd scenario is using ALE in diff sap system / diff client
3rd scenario is using ALE in legacy to sap system.
the data to be transferred:
a) from Purchase order to Sales order
b) from RFQ in one client to RFQ to another client.
Please provide me your valuable help on configuring ALE & RFC on this. since this is standard project, i would like to use maximum standard object on developing the above requirements.

Hi Basha,
Do you need to display the header items and detailed items?
If the BAPI Contains Output values in R/3 side.
I mean to say if BAPI contains 4 line items.u can get thru wdjava the followinf way.
1. Create webdynpro application.
2.Import the model.
3.Create Customcontroller and model binding .
4. Write the execute method in controller.
BAPI b = new BAPI();
WdContext.node<BAPI>.bind(b);
give inputs for BAPI
b.setname(" ");
b.setno("");
wdContext.currentBAPI().modelObejet().execute();
wdContext.node<output>.invalidate(); in try catch
5. create view or when u give the dynpro application its
in the add custom to view and drag BAPI custom to view .
6.Crete UI for ur table thru insertTemplate table directly mapp the output values.
7. deploy and run
U can get the out line items .
Or any thing else post ur requirement.
Thanks

MDM catalogs to be used for PM-SRM scenario

Hello All,
We are in a situation where we are using the SRM-MDM scenario for regular shopping carts. And also would like to leverage these MDM catalogs for purchases made in ECC Plant Maintenance "work Orders" for non-stock ECC material numbers maintained in ECC.
These material numbers in ECC will have a Manufacturing Part Nmber (MPN) in the material master data.
Since we had some difficulty connecting these SRM-MDM catalogs directly to the ECC work order we would like to bring these requisitions generated by "Work Orders" and push them to SRM. (Standard SAP)
Once these Requisitions come into SRM as SC.. the system automatically approves this SC (Which is standard SAP) but in this process we would like to know if there is a way the system can automatically make a call to MDM based on the Manufacturing Part Number (MPN) and bring in the price and the vendor details back to the SC automatically.
Currently we are using SRM 6.0 and MDM 2.0 in our landscape..
Any suggestions will be appreciated and rewarded..
Regards
SRM6.0 Ramp-Up-Customer

ALE/IDOC complex scenario

The scenario is a little weird but this is what I need to do.
I want to send idoc from ECC 5.0 to 3.1I and then to external system. I did succeed in sending idoc from ECC 5.0 to 3.1I but not further to external system. How can I achieve this scenario using ALE. A detailed step by step approach would be helpful and appreciated.
This is what I did and didn't succeed. In the inbound partner profile, I maintained outbound parameters which points to port and RFC destination to external system so that whenever the idoc comes in the 3.1I system it sends the same to external system. I didn't maintain the distribution model from 3.1I to external system which I think worthless. Pls note that I cannot change the architecture in any way. And would like the suggestions to be in sync with the architecture. Thanks a lot and appreciate any help
Thanks
Ricky

Did you see the recent blog on this?
You need to determine whether a standard message / IDOC exists for the object you are dealing with.

Where we use Conversions like Fixed Value and Value mapping?

where we use Conversions? like Fixed Value and Value mapping?

Mostly say when u have a scenario like converting a value in the source to a another in
target. Say in source it might me KM but in target u might need Kilometers and u hav multiple entries like this.

Transfer history notifications from one system to another using ale/inotif

Hi experts,i wan't to transfer 15000 completed,historical notifications from one sap system top another.
I use ale configuration to do this.
I have set rfc connections,message type,distribution model and i've generated partner profiles.
My question is how can i create thenotification idoc?
In MM with message type matmas using transaction code bd10 we send materials creating idoc.In my case for notifications i read that i can do this using transaction code inot.But i am doing this and a mesage:notification rejected appears.
I then try to distribute the model and a rejection message appears with
Reason: Distribution model is currently being processed .
Can you suggest something??
I've read tha i might will need to create badi..

Hi Dear,
its possible only with the help of ECM , you need to do some work around too.
ECM should be extended to include the classification. In fact, the EXACT SAME change number should be used. In PLM, it's important that all of the changes related to a material become active in a cohesive unit. We can talk about those details if you need some background.
Unfortunately, in the split-client scenario, you're toast on any hope of using the same ECM number, due to the internally defined number range. The best you can do is create a new, externally assigned number range in the production client, and generate the number internally in the staging client. You can then make the change in the staging client and ALE it over to the productive client.
The next nasty part is going to be retroactive changes. You can't simply back-date a change. You have to change every occurrence of a dependency, class, characteristic, etc, that has existed in production as of that back date. So, the smartest practice is to never allow any back-dated changes. Require orders to be cancelled and re-created with the new effective date.
Check and revert back.
Regards
Ritesh

Help: one request using ALE&IDOC to Posting Goods Issue about MaterialScrap

Hi Exports,
i got a situation. My client is using ALE&IDOC to deal with the Material Scrapping. The business scenario is:
1. One third system (Non-SAP) Send IDOC to SAP Production Server through the Intermedia SEEBEYOND.
    Message Type: MBGMCR
    IDOC Type: MBGMCR02
    BUSINESS OBJECT: BUS2017
2. SAP Production Server use "Message Type: MBGMCR" to find out the BAPI in Distribution Model and trigger the BAPI.
the Distribution Model:
Model View
SEEBEYONG
PRODUCTION
GoodsMovement.CreateFromData
Reciever determination: no filter
Now my client's request is:
When the Movement Type is 551 in the IDOC Segment "E1BP2017_GM_ITEM_CREATE", This IDOC will be ignore and not trigger the BAPI to post goods issue.
i try to add the destination filter in the Distribution Model. but when i add the filter group, there are only two filter parameter ("Plant" and "Storage Location") and don't allow to add others.
i have no idea now. can anyone give me a favor. thank you very much in advance.
