CRM IDOC Segments Changing in PI mappings
Hi All,
I had configured a scenario from CRM to PI and to SQL Table.
When ever a BP is Created or Changed an idoc with that BP is sent to PI and to SQL. I had used this IDOC(CRMXIF_PARTNER_SAVE) for mapping.
When i send BP of Person type the IDOC Segment is getting Changed and Mapping error occurs.
So please suggest me whether to use IDOC or not?
Is there any Adapter i can use for real time?
I need to get data of BP automatically.
Thanks in Advance.

Did you try change pointers..........

Hi All,
How can We modify or append a segment to the inbound IDOC. The scenario is as follow
We have an inbound IDOC to create/change contract order. There are some segments in the IDOC to hold the error records.
while processing the inbound IDOC we need to fill these blank segments with relevant data, so that we can reprocess the IDOC with ease.
I am trying the modify the IDOC_DATA inside the processing function module. Till the end of the function module IDOC_DATA is having the added segment data, however when I am checking from WE02, the segments are appearing to be blank.
Please let me know, what is missing above.
Thanks & Regards
D. PradhanWhich exit / BAdI are yous using for adding the segment & what is your inbound processing function module ?
Anyways i also had the same problem a few weeks back i was trying to delete a segement though
My understanding is in WE02 it displays the data from EDIDC & EDIDD. In your I/B processing FM you only modify the data in the IDOC_DATA table & not in EDIDD.
Check in EDIDD, the segment would not be there.

My IDOC segment change should reflect ONLY for 1 extension
Hello
I have added a additiona/new field to a custom segment. And this segment is used in 2 IDOC extensions, say Z_ORD_1 and Z_ORD_2.
But, we are interested only in Z_ORD_1 extension. So, some how can i restrict that my additional field should point only to Z_ORD_1 and its associated processing FM.
Because, there is no change in Z_ORD_2 processing FM and all its associated interfaces/XI stuff.
Can i restrict my change only should applicable to Z_ORD_1?
Thank youI do not think we can restrict at segment level to point only to a particular extension...
Suggestion would be control at data level before creating IDOC...you can check the extension fill the field accordingly...
if that field is not filled, IDOC will not take it in output structure...

Idoc Segment Changed- Support Packs
Hii All
In our SAp system (SAP ECC 6) support packs were implemented. After the implementation one of the segment of the idoc (Basic Type:- SHPMNT03) got changed infact that segment now does not exist.
Its a business critical issue, can anyone do let me know what to do in such scenario.
Thanks & Regards
Gaurav ManochaSomehow I find it hard to believe... The IDoc structure is not supposed to be changed. If there is some kind of an upgrade, then instead of changing the IDoc, SAP creates a new version. That's why we have ORDERS01, ORDERS02, etc. The IDocs are supposed to be downwards-compatible.
I'd guess that either the standard IDoc was extended in your system and the extension is the one that's missing or there is some kind of a mistake. If it wasn't an extension, you'd definitely should contact SAP about it (check the OSS notes first though - maybe it's already a known issue). -
Unable to change the length of field in idoc segment
Dear all,
My requirement is to change the length of a field(Z field) in a segment (Z Segment). I tried the following but in vain
1)Tried to Cancel the release and then change the length of the domain. Unfortunately it is givin an error saying "Error while resetting release of segment ZC9DEMARA01".
I also tried cancelling hte release of extension and then cancelled the release of segment
2) Created a new version, but in new version the earlier fields are diabled. So I am unable to edit.
I have gone through some of the links available in SDN but I could not solve as I am unable to cancel the release in the first step.
[Idoc segment field length changes]
Could you please help me.
Thanks in advance!
regards,
AravindHello Aravind,
I Have created one Segment type with some fields, changed the field length also its working.
just try to cancel the release and change the length of the filed and do it set release again.
Try it .

Idoc segment field length changes
Hi friends,,
I am new to idoc.
My requirement is in my segment
i am having 5 fields and also this segment is already realeased one.
i wnat to change the field length from 10 to 20 . how to do this ?
actually what i did is
1. i cancel the release for that segment.
2. in that field inside the dataelement i changed the field length from 10 to 20.
3. data elemnt get chaged from 10 to 20 but Export length for that field in Idoc segment still retain the 10 only
can you plz how to resolve this
devaHi,
The way you used is right. ( cancel release or create a new segment )
After you cancel release, try delete that field, and insert a new one.
If it isn't valid still, create a new segment instead.

Any FM/methods to update idoc segments without changing idoc status
Hi All,
My requirement is a reprocessor program which fills up some fields in the idoc segment before posting. So, after updating the segments, the idoc status should remain as before.
Is there any function modules or methods to update idoc fields in segments without changing the idoc status?
I have tried the FMs EDI_DOCUMENT_OPEN_FOR_EDIT, EDI_CHANGE_DATA_SEGMENT and EDI_DOCUMENT_CLOSE_EDIT, but it changes the idoc status.
Thanks,
Arun MohanAs for FM to do this, i don't know if there are any, but i think you can go directly to the tables with the IDOC data and change them without triggering the changes in status like FM do. Still, i am not sure this is completely true, but you could give it a try. Also, i don't know if this is the best way to do it, because of those legal/audit questions mentioned by Thomas.

Hi,
How can i change the field attached to a IDOC segment.
Actually we have this Invoice IDOC,in which the E1EDK03 012(Qualifier) is passing the IDOC creation date instead of Billing date.
So i need to change this mapping to Billing date.
Please help.Hi Salz,
I just checked my version of SAP (4.7) and you should get an invoice date. Check out the subroutine FILL_E1EDK03 in function module IDOC_OUTPUT_INVOIC. The first section of this code creates an E1EDK03 segment with the invoice date (if there is an invoice date), with qualifyer 026.
Is there a possibility that in fact you are getting an E1EDK03 segment with the invoice date, but you are also getting other E1EDK03 segments (such as the one you mention with qualifyer 012) and they are obscuring the one you are looking for?
If there are definitely none being created then can I suggest that you debug the subroutine FILL_E1EDK03 in function module IDOC_OUTPUT_INVOIC to check what is happening. You may need to change the timing of your output record to 1 and run the program RSNAST00 online to get the breakpoint to be hit correctly.
If, in your version, the code doesn't include this date, then you have an exit function module EXIT_SAPLVEDF_002 (called via the subroutine CUSTOMER_FUNCTION in function module IDOC_OUTPUT_INVOIC) where you can actually add your own segment data. For example you an change the contents of an existing segment (as per your original request), or append your own E1EDK03 segment with your own data. I would recommend adding your own segment rather than changing whats there.
It is possible to extend idocs to add your own custom segments (eg Z1EDK03), but I wouldn't recommend it in your case, because in later versions of SAP the date is provided and by not creating a new segment (Z1EDK03) you will have no mapping changes to do when you upgrade. You can just delete your userexit code.
Hope that all makes sense and helps you with your problem.
Cheers,

is this condition is getting satisfied everytime since you are modifying only on this condition.
I couldnot understand you comments as its not in English, however i tried understanding your logic,seems correct .

RE: How to change Idoc segment data
Hi folks,
I have a requirement where in I have a Inbound DELIN Idoc in the SAP system. When I am reprocessing the same Idoc through WE19 by changing the delivery schedule and then changing the E1EDP16-WMENG value in runtime while debugging, the same is getting updated in correponding SDSA but when the new Idoc is getting triggered, only previous old Idoc value is getting reflected.
Kindly suggest!!!!
Vishal.No I dont want to change the value in WE19.... In runtime I am changing the value of schedule Line quantity and the same is getting update in SDSA also but when a new idoc is getting created that value is not getting reflected in that Idoc segment field.
Kindly suggest. -
Changing filed name description - idoc segment creation/change
HI,
is it possible to change the fieldname description in an IDoc Segment without changing the DataElement ?
Exampel:
I Used CHAR40 as dataelement for my own ZZFIELD. In the Idoc the fieldname description of the data element CHAR40 is shown.
Can i change this description ?
thx,
GordonNo, The IDOC always displays the texts based on the Data Element which is assigned to that field. If you want to display your own text you have two options:
1. Create an enhancement and change the text of the data element which is not recopmmended because it will be changed wherever that data element is used.
2. Instead just create an own data element where you can maintain any texts you need.
Hope that helps,

Idoc Segment Cancel release error
Hi all,
I have problem in cancelling the release of an Idoc Segment. I have a requirement to add new fields to the segment. When I try to do Edit->Cancel Release it is throwing below error.
"Error while resetting release of segment Z1PXXXX
Message no. EA259"
Could anyone tell me how to overcome this error or the root cause of this error?
Many Thanks,
Sri
Edited by: Arunsri on Nov 10, 2009 8:37 AMHello,
The reason that you are getting these errors is that you cannot cancel
the release of an extension made in previous version e.g. 4.6C. Instead you have to
create a new extension.
It is not possible to change a segment definition which is released in a
lower release. This is a basic concept of our release strategy to
guarantee compatibility between different releases.
You must create a new segment definition for the new release e.g. 620 with a new segment
field with the appropriate length. In transaction WE20, outbound parameters, you can specify
the "segment release in IDoc type" for the communication. Please read the F1 help of this field for further
information.
For your own segments you can define a new version of the segment via
transaction WE31 -> Add Version (Shift+F5).
Please review your online help for more information on this and related topics.
Hope this information helps.

Custom idoc segment fields not populated
Way back in 1999 someone create a custom Idoc type with custom Idoc segments in it. Unfortunately, they forgot to release one of the segments.
Recently a change was request to add new fields to this custom segment. In order to get the fields transported the segment had to be released.
All worked fine in Dev and the new Idoc segments were populated as expected. However when the idoc segment was moved to the test system all visually appears to be fine but when the idoc is created (status 50) the new fields are not popultated.
In 40B the start of the inbound process was IDOC_INBOUND_DATA. Does anyone know what the new starting point is in 4.7??
I beleive the error is actually that SData is not reading all the input values and stopping right where the old fields end in teh custom segment.
Thanks,
Anthonyadditionally,
SAP will not allow us to release the basic idoc type because it was released in 40B. It also will not allow us to cancel the release since we are now in 620. So, unless anyone has input for this I think the only solution will be to create a successor IDoc type and change our apps to use the new IDoc type with it's enhancements. -
Adding field in standard IDOC Segment E1EDL24
Hello Friends,
I have an urgent requirement that I have to extend IDOC segment E1EDL24 with two fields PABNR and LFSNR.
When I tries to change the segment in WE31, it shows an error message that you can only modify the segments of customer namespace and cannot modify Standard IDOC Segments.
Can we modify the standard IDOC segments, and if yes, how can we modify the standard IDOC segments. Please clarify.
Points will be rewarded generously.
Regards,
NavinHi Naveen,
We cannot Modify the Standard segments. But we have to Create a new Segment and Add these fields.
Then Create an Extended Idoc type
Implement User Exits in Outbound And Inbound ..
This is the Complete Steps and Info on this...with an Example...
Enhancing ALE
For example, if in an outbound interface you find that the IDOC type does not contain all the data you need to pass to the other system, you can extend the IDOC to accommodate the additional fields and enhance the ALE function modules to populate the fields. Similarly, if in an inbound interface, there is additional data that needs to be posted to the R/3 application, you can extend the IDOC type to have additional fields populated by the external system or translator or the other R/3 system and then enhance the inbound ALE function modules to post the additional data to the R/3 application.
let us use the SAP Customer Master application as an example. Specifically, letâs focus on the IDOC extension and ALE function module enhancement of IDOC type DEBMAS02 and message type DEBMAS (Customer Master) and the IDOC reduction of message type MATMAS.
IDOC EXTENSIONS
Letâs first look at the concept of IDOC extension. SAP delivers Basic IDOC types such as DEBMAS02, MATMAS02, ORDERS02, and WMMBID01. By extending the Basic IDOC type, you are actually creating a new IDOC type. You create a new segment with the additional fields. This new segment has to be associated with one of the existing Basic IDOC segments. Then you create a new extension type, which is associated with the Basic IDOC type. This results in a new IDOC type. In order for ALE function modules to relate to this new IDOC type, the IDOC type is linked to the corresponding message type.
Note that you should not add fields to existing segments but should create a new segment and associate it with an existing segment. This, in a nutshell, is the process of creating IDOC extensions.
In our example, the Basic IDOC type DEBMAS02 is used to communicate Customer Master data to the SAP Customer Master application. Even though the application has a screen to enter and store a contact personâs business address (see Figure 1), DEBMAS02 does not have a segment or fields that communicate the contact personâs business address. If your business requires that this business address be communicated to the other system through the ALE interface for Customer Master, then you have to extend the DEBMAS02 IDOC type, and enhance the corresponding ALE function module.
In DEBMAS02 the contact person fields are present in segment E1KNVKM and the business address of the contact person is stored on the SADR SAP table. You need to create a new segment, Z1SADRX, that is associated with E1KNVKM. This will be done in the process of creating an extension type ZDEBMASX. This extension type will then be associated with a new IDOC type, ZDEBMASZ. IDOC type ZDEBMASZ will be linked to message type DEBMAS for Customer Master. The final step in the IDOC extension process is to check the new objects. This check also verifies the structural integrity of the IDOC type. Letâs look at each of these steps in more detail.
1. Create an Extension Type and a New Segment.
Determine the fields on table SADR that you are going to provide for in the new segment Z1SADRX. You need fields for name, street, city, region, and country to give the business address of the contact person. You also need fields for the address number. ADRNR is a field in SAP tables such as SADR that uniquely identifies the address of an entity. This field is cross-referenced from other tables to the SADR table to obtain the full description of the address. Because this is an IDOC type for master data, the first field of the new segment will be MSGFN. The message function field informs the receiving system of the action to be taken for that particular segment. In the code that you write for populating the new segment, the value of the message function is the same as that of the parent segment E1KNVKM. In all, you will have 12 fields in segment Z1SADRX (see Table 1).
To create an extension type and new segment:
Use transaction WE30 or from WEDI go to Development -> IDOC types.
Enter ZDEBMASX for Object Name.
Choose Extension Type.
Click on Create.
You will see a pop-up screen. Choose Create New, and enter a description. For version 4.x, enter DEBMAS02 in the Linked Basic Type field. Enter.
You will see a screen with ZDEBMASX and its description in the first line. Click on this line, and press Create. For version 4.x, expand the tree of segments, and place the cursor on E1KNVKM.
You will see a pop-up screen. Enter E1KNVKM as the reference segment. Enter.
For 4.x, press Create after placing the cursor on segment E1KNVKM.
You will see a line appear with E1KNVKM hierarchically below ZDEBMASX, with a description "Customer Master contact person (KNVK)."
Click on this line and press Create. You will receive a message indicating that the new segment being created will be a child segment of E1KNVKM. Enter. A pop-up box appears for the new segment.
Enter Z1SADRX as the segment type, 1 for Minimum, 1 for Maximum. Leave Mandatory segment unchecked. These entries imply that there is only one Z1SADRX segment for every occurrence of the E1KNVKM segment, and also that this segment is not mandatory. Note that if the parent segment is not mandatory, then the child segment should not be mandatory, because this could result in a syntax error during the creation or processing of the IDOC.
For 4.x, you must first create the IDOC segment Z1SADRX (Iâll explain why in a moment) from the menu path WEDI -> IDOC -> Development -> IDOC Segment.
Click on Segment Editor.
On the next screen, click on Create.
Enter a development class for the object. Enter.
This will take you to the screen for segment definition. Enter a description for the segment. Enter the field name, data element, and the data element documentation name. In most cases, all three fields may have the same values. If you are using a field in the segment that is not present in the ABAP/4 data dictionary, you must first create the domain, data element, field, and appropriate documentation before using it in the new segment.
Enter these three columns for all 12 fields. Save.
Click on Generate/Activate, F3 to step back.
From screen Maintain Segment, go to Segment Type -> Release. A checkbox now appears beside the segment definition Z1SADRX (see Figure 2). Check this box. Save.
Save again to store the descriptions of the segment, F3 to step back.
Save the extension type.
It is possible to have several new segments with relevant Basic IDOC type parent segments in a single extension type. However, you can form only one IDOC type based on a single extension type.
2. Create an IDOC Type.
The next step is to create an IDOC type by associating the extension type that you created with the Basic IDOC type. This is a simple process:
From transaction WE30 or WEDI go to Development -> IDOC Types.
Enter ZDEBMASZ for Object Name.
Click on IDOC Type.
Click on Create.
Enter DEBMAS02 for Basic IDOC type.
Enter ZDEBMASX for extension type.
Enter a description.
Enter.
You will see a display of the composite IDOC type with all segments, including Z1SADRX (see Figure 3).
It is possible to associate only one extension type with a Basic IDOC type for a given IDOC type. However, you can have multiple new segments in an extension type.
3. Link IDOC Type to Message Type.
The next step is to link the new IDOC type to its corresponding message type. This is important, because this relationship is referenced in the partner profile parameters where you specify the message type and IDOC type to be used for that particular representative system. To link the message type:
Use transaction WE82, or from WE30, go to Environment -> IDOC Type / Message Type, or from WEDI go to Development -> IDOC Type -> Environment Î IDOC Type / Message Type.
Click on Display <-> Change.
Click on New Entries.
Enter DEBMAS for message type.
Enter DEBMAS02 for Basic IDOC type.
Enter ZDEBMASX for extension type.
Enter your SAP R/3 release number for Release.
Save.
This data is stored on the EDIMSG table and is accessed by several ALE processes to relate the message type to the IDOC type.
4. Check the IDOC Type.
Before checking the IDOC type for consistency, it is important to perform another step that releases the extension type to the IDOC type:
From WEDI go to Development -> IDOC Types -> Extras -> Release Type, or from transaction WE30 go to Extras -> Release Type.
For the Object Name ZDEBMASX and radio button Extension Type, click Yes.
The extension type has now been "released."
You canât edit the extension type once itâs released. To cancel the release for further editing or deactivation, go to WE30 Î Extras Î Cancel release. The final step in the IDOC extension process is checking the validity of the IDOC type:
From transaction WE30 or WEDI go to Development -> IDOC types.
Enter ZDEBMASX for Object name.
Click on Extension Type.
From the Development Object menu select Check.
Repeat the operation for IDOC type ZDEBMASZ.
A check log will be generated for each run with details of correctness or errors (see Figure 4).
In some situations it is possible to receive errors during the check process, especially segment length errors. The incorrect IDOC segment can be repaired and corrected by executing program RSEREPSG. This program checks the formal consistency and repairs incorrect segments. In test mode it will generate a log of formal correctness for the specified segment only. For the program to repair segments in normal mode, the underlying IDOC structures (DDIC structures) must be active. This program rectifies the lengths of the DDIC structures and not the fields themselves. RSEREPSG can also be used to change the person responsible for the object and the release flag.
Menu paths may vary slightly depending on the release/version of SAP R/3, but the procedures and the principles are the same.
ALE FUNCTION MODULE ENHANCEMENTS
Having extended the IDOC type to contain additional fields for an inbound or outbound application, you now want to enhance ALE function modules for populating the additional segment on the outbound or applying the additional segment data on the inbound application.
The core working code for ALE processes for a given application area is always encapsulated in ABAP/4 function modules. These function modules are associated with such control information as message types and process codes. So the ALE process checks this control information and derives the name of the function module to invoke for that particular IDOC processing from certain database tables. These function modules contain objects known as customer functions, which can be considered SAP Enhanced user exits. A function module is called at a particular point during the processing of the main program or function module, and it can be used to influence data processing at that point by adding code to the customer function. The customer function behaves like a normal function module and has import and export parameters, tables (internal tables) statement, and exception processing. Unlike a conventional user exit, customer functions give you the ability to modify only data available to you by the function moduleâs parameters and internal tables. While most ALE/EDI function modules are supported by customer functions, there are ALE/EDI processes that still use conventional user exits. There are a few ways to determine which function module to enhance for a given message type/process code:
For master data distribution, from SALE go to Extensions -> Master data distribution -> Setup additional data for message types. Search for message type DEBMAS in this example. You see an entry for DEBMAS associated with function module MASTERIDOC_CREATE_SMD_DEBMAS. This data is stored on table TBDME. The function module names for all master data message types follow this pattern: MASTERIDOC_CREATE_SMD_messagetype. This function module calls another function module of name MASTERIDOC_CREATE_DEBMAS or MASTERIDOC_CREATE_messagetype. Search for the words customer function, and you find several hits that can be used to add code to the function module.
From WEDI got to Control -> Inbound process codes -> Inbound with ALE service -> Processing by function module (transaction WE42), or from WEDI go to Control -> Outbound process codes -> Outbound with ALE service -> With function module (transaction WE41). There will be function modules associated with the process codes. For inbound, the function modules usually follow this pattern: IDOC_INPUT_messagetype: for example, IDOC_INPUT_CHRMAS for inbound characteristics master.
Use transaction WE57 or from WEDI go to Development -> Message/Application Object. The entries list the function module, Business Object, message type, and IDOC type that are used for inbound ALE/EDI interfaces.
Customer functions are not specific only to ALE and EDI but also to all programs/modules in SAP R/3. Customer function is a SAP enhancement component; the other two types are menu and screen enhancements.
All customer function exits are maintained in SAP enhancements and are found by using transaction SMOD. After executing transaction SMOD, pull down (F4) on the enhancement name field, and execute again. This provides you with a list of all SAP enhancements available. SAP enhancements are grouped by development class pertaining to an application area. Choose Application development R/3 SD master data distribution for development class VSV to lead to a screen that lists VSV00001 as an enhancement (see Figure 5). Press Component +/- to display its function exit components. There are four possible components listed, all of which are function exits (and are function modules) that are called from the ALE function modules in the form Call Customer Function Î001â. This is a special occurrence of the ABAP statement Call. Go to item Exit_SAPLVV01_ 001, which you need to enhance for the Customer Master outbound example of an IDOC extension. In the ALE-function module MASTERIDOC_CREATE_DEBMAS, the statement CALL Customer Function 001 is translated in the background to call component EXIT_SAPLVV01_001. Although this function exit can be edited using transaction SE37, you will use a simpler approach.
When you use SAP enhancements and their components, you manage them with an SAP object known as a project, which is like an envelope containing the selected enhancements and their components. A project can be used to control the execution of components and to transport them to other clients and instances in SAP. Basically, the process involves creating a project, including enhancements and components that are to be enhanced, editing the components, and then activating the project. The following process creates a project for our example Customer Master IDOC extension:
Execute transaction CMOD.
Enter name of project, say CSTMAST1.
Click on Create.
Enter a description of the project.
Save.
Click on SAP Enhancements.
Enter VSV00001 for Enhancement.
Save.
Once youâve created the project, edit the function exit components and activate the project. Remember that the code in the function exit enhancement will execute only if the project is activated. In fact, this is a convenient SAP enhancements feature, whereby the work in progress (developing code in the customer function) will not affect users of that application. When the code is completed, the project can be activated so the enhanced functionality takes effect. It can also be deactivated for maintenance.
As mentioned earlier, customer functions (function exits) are embedded in ALE function modules and can be used to influence the creation and modification of IDOC data on an outbound application or to post additional or modified IDOC data to an inbound R/3 application. Function exits are similar to regular function modules, with import/export parameters, tables (internal tables), and exceptions.
The two important factors to consider while developing the customer function are:
1. The point in the ALE function module where the function exit occurs
2. The data made available by the customer function that can be modified or posted to the R/3 application, based on the direction.
Because some function modules have several customer functions, it is critical to choose the function exit best suited for that particular enhancement. Do not attempt to perform activities that the function exit is not designed for. The importance of this point is illustrated by the following description of enhancing function modules for outbound and inbound ALE interfaces.
Outbound interfaces. In an outbound ALE interface you use function exits (customer functions) to populate additional segments created by an IDOC extension or to modify the existing IDOC data segments as per business requirements. Previously, you identified that enhancement VSV00001 has a component EXIT_SAPLVV01_001 (function exit), which can be used for populating the additional data segment Z1SADRX that you created in the IDOC extension ZDEBMASX (IDOC type ZDEBMASZ, based on Basic IDOC type DEBMAS02). You also learned that the ALE function module that calls this function exit is MASTERIDOC_CREATE_DEBMAS, which has a statement Call Customer Function 001.
Browse the function module MASTERIDOC_CREATE_DEBMAS using transaction SE37. You will find that this customer function is invoked for every segment of IDOC type DEBMAS02. In fact, the function exit is called soon after the creation of an existing segment has been populated with data and appended to the IDOC data table (internal table). Also, the function exit is exporting the message type, IDOC type, and the segment name and is importing the IDOC extension type. It is also passing the IDOC data internal table. This indicates that the ALE function module is allowing you to populate additional segments for every existing segment and modify the existing segmentâs data.
Letâs write ABAP/4 code to accomplish the task of populating IDOC segment Z1SADRX with a contact personâs business address:
From SE37, display function module MASTERIDOC_CREATE_ DEBMAS.
Find Customer Function 001.
Double-click on 001.
The function EXIT_SAPLVV01_001 will be displayed.
Double-click on INCLUDE ZXVSVU01.
You will be asked to create a new include object. Proceed as desired.
Enter code (as in Listing 1).
Be sure to perform a main program check (Function Module -> Check -> main program) and extended program check (Function module -> Check -> Extended check).
Now that you have extended the IDOC and enhanced the ALE function module based on the requirements for the contact personâs business address on the Customer Master, letâs test the interface. You should create a logical system and define a port for this interface. You should also configure the Customer Distribution Model to indicate that message type DEBMAS is being distributed to this logical system. The only difference in configuration between a regular outbound ALE interface and an enhanced one is the partner profile definition. While maintaining the outbound parameters of the partner profile, make sure the IDOC type is ZDEBMASZ. The fields for Basic IDOC type and extension type are automatically populated with DEBMAS02 and ZDEBMASX, respectively.
To maintain the contact personâs business address of a customer:
Use transaction BD12 or from BALE go to Master Data ->Customer -> Send and send that Customer Master record by executing the transaction after filling in the relevant fields such as customer number, message type, and logical system.
Use transaction WE02 or WE05 to verify the IDOC created. You should see the new segment Z1SADRX populated with the correct data.
With SAP releases below 4.5B, you cannot capture changes to business address through change pointers because a change document object is not available for capturing business address changes, and also earlier releases have not been configured to write change documents for a contact personâs business address. If you would like this functionality, you can either create change document objects, generate function modules to create change documents, and perform ALE configuration to tie it in, or make a cosmetic change to the contact person screen data while changing the contact personâs business address so that it gets captured as a change to the Customer Master. Subsequently, the ALE enhancement that you performed captures the contact personâs business address.
Inbound interfaces. The process for enhancing inbound ALE interfaces is similar for outbound, with a few exceptions; specifically in the coding of customer functions (function exits) for the ALE/EDI function modules.
The first step is to create an IDOC extension for the specific Basic IDOC type by adding new segments at the appropriate hierarchy level: that is, associated to the relevant existing segment. Populate the data fields on the new segments with application data by the translator or external system/program before importing them into the R/3 System. Then, find the ALE function module that is invoked by the inbound processing. By browsing through the code or reading the documentation on the function exit enhancements using the SMOD transaction, identify the function exit in which you should place your code. The technique used in the code to post the additional or modified IDOC data to the application can vary based on the application rules and requirements, the data available at that point in processing, and the application function modules available to update the application tables. It is important to search first for application modules that process the data and see if they can be called within the function exit. If the additional data in the extended segments in specific to a custom table or resides in nonkey fields of a single or small set of tables, you may be able to update it directly by SQL statements in the function exit. This approach should be carefully evaluated and is certainly not highly recommended.
Another option is to use Call Transaction from within the function exit to process the additional data. For example, in the case of message type WMMBXY for inbound goods movements from a warehouse management system, the standard interface creates batches for materials, but does not update its characteristics. In such a case, you can use Call Transaction MSC1 to create the batch and assign characteristic values to it from within the function exit provided.
Error handling is a very important consideration when making enhancements to inbound ALE/EDI objects. In ALE and EDI inbound processing, workflow is used for handling errors at different levels such as technical and application. If workflow has been configured for the interface, the error messages and workflow items flow to the inbox of the named recipient(s).
It is also critical to enhance the workflow that handles notifications of the inbound ALE/EDI process. In most scenarios this is not a very difficult task because SAP lets you influence the workflow parameters and messages in function exits (customer functions). You typically do this using flags and message codes to trigger certain workflow actions. If you conform to the status codes and flags stipulated for workflow processing, the enhancement could be error-free and seamless. In the case of an inbound IDOC with an extension, you should populate the EDIDC fields IDOCTYP (new IDOC type) and CIMTYP (extension type) accordingly.

How can I send an update to CRM Middleware after changing BUPA longtext
Hi folks,
I am looking for the easiest way to send an update/insert of BP longtext change to SAP CRM Middleware (& MobileSales). I have implemented save of the text with function save_text within of a CRM application for changing bp data.
Text is available to standard CRM transaction bp, but now updates have been send to subscribed Mobile Sales clients.
I have already checked the bapi_bupa* functions, but it seems that they contain no notes/longtext segment.
Thanks for any help.
DanielHi Daniel,
just wondering if you had a solution for this as I have the same issue to solve as well.
thanks, regards.
