Issue of grouping IDOC segments in huge loads

Hi All,
My Scenario is File to IDoc. No problem in posting IDoc in R3. But when i see the Idoc structure in R3, all the data records are grouped in different segements as seen below:-
This is how i see in we05.
IDoc No (00000000001234)
- Control Rec.
- Segments 000001 to 001000
- S01 Segment 000001 (Actual records)
- S02 Segment 000002
- S03 Segment 000003
- Segments 001001 to 001001
- S04 Segment 000004
- S05 Segment 000005
- S06 Segment 000006
- Status Rec.
I dont want the grouping of Idoc segments to take place. It should be under same data segment.
Please provide me your valuable solutions to resolve the same.
Note: This problem occurs only when processing huge records.
Thanks in advance,

Hi Sriram,
It is the standard program flow of transaction WE02 which checks the number of segments.if the count is more than 1000,it creates a another group and displays it for the sake of readability.
Anyway it does not affect the inbound processing of the IDOC.
Thank you.

IDoc segment version issue in ECC upgrade from 5.0 to 6.0

Hi experts,
we are in the process of upgrading our ECC environment from 5.0 to 6.0. We have quite a few interfaces which use ORDERS/Invoice Idocs in customised form. In ECC5.0 environment, we had developed a Z segment in the ORDERS Idoc and the segment release was set as 640. Everything worked fine in ECC5.0.
In upgraded environment, SAP has released new version of some segments. one of those is E1EDP01. This segment has 2 new versions in ECC6.0 environment - 007 and 008. This change in the version changes the data in the IDoc and hence interface goes in error at the EDI provider.
We have tried to use 640 as the IDoc segment release in the partner profile of the IDocs. This still gives us an issue because the 007 version of the segment E1EDP01 has release 620 and hence the Idoc picks up 007 version instead of 006 version as desired. When we change the partner profile with Segment release in the IDoc type as 46C, it gives us an issue in the Z segment saying that the IDoc segment is not released in 46C and the Idoc goes in error.
has any one faces such situation in the past? if yes, please throw some light.
Thanks in advance.

Please let me know if your issue was resolved. I have similar issue now.

Idoc Segment grouping

Hi All,
I am new to ALE Idoc. I have created few Idoc segments.
Later I have found that i am using few segments in same sequence.
I have thought that if i group these segements into one segement then it will be helpful for me in future.
Please do let me know, by any means can i acheive this.
Thanking you in advance.

Hi
It seems that i am unable to convey my requirement in last post.
Sorry for that.
I will explain it by the example.
I have defined Segements Seg1, Seg2, Seg3.
Now while defining basic type, i am using these segments as
Seg1 <<Parent segment>>
Seg2 <<Child Segment>>
Seg3 <<Child Segment>>
I have observed that i need to create the same structure using these 3 segments in <b>different basic types</b>.
Hence if i club these 3 segments into one group or....
and use that group or... while defining new Basic type.
Please do let me know if i am not able to convey the requirement.
If this can be acheived bu some other mean then do let me know.
Thanking you in advance

Issue with IDOC segment creation..

hi,
i created an idoc segment thru we31. when i was saving it, and when the transport request was asked, i cancelled it. it so happend that the underlying structure was created (i was able to see that in se11) but in we31, the segment definition did not appear and i got the message "segment does not exist yet".
so in se11, i deleted the associated structure and tried to recreate the segment, i am not able to !! while saving, i get the error "you do not have authorization for delete for function idoc segment"
when i performed a segment check (ctrl + F1), i got the message,
Repository structure missing for segment ZZZ |
Inconsistent overall length in segment version 000
Segment version 000 not released
Entries exist in table of Segments for segment ZZZ
Entries exist in table of Segment definitions for segment ZZZ
Entries exist in table of Segment structures for segment ZZZ

what shud i do ?

resolved. seems some authorization was missing. thks

IDoc segment issue

Hi,
I have file to Idoc scenario, where my input file structure like below and need to create Idoc segments in SAP.
Input Structure:
Record (1--Unbounded)
Header (1-1)
Item_Details (1- Unbounded)
Child_ItemsInfo (1 -Unbounded)
Item_1 (1--1)
abc
def
Item_2 (1--1)
abc
def
Item_3 (1--1)
abc
def
Now..I need to generate an Idoc segment "Z1ABCD", as many as child Item segments(Item_1,Item_2,Item_3) occurs in my input structure. I have used duplicate subtree on Idoc segment "Z1ABCD" and copied 2 more times.Now I have 3 "Z1ABCD" segments in my IDoc.
Lets say, if my input structure have 2 Child_ItemsInfo, then I need to generate 6 "Z1ABCD" segments in Idoc. I'm able generate these segments.
My code generating all the Item_1 segments then Item_2 segments like that...But I'm expecting a "Z1ABCD" segment at Item_details node level...like Item1,2,3 and then Item1,2,3....Please help me out!
Note: My mapping looks like this;
Item_1 ->remove context>Split by value(each) ->CollapseContext->Z1ABCD
Item_2 ->remove context>Split by value(each) ->CollapseContext->Z1ABCD
Item_3 ->remove context>Split by value(each) ->CollapseContext->Z1ABCD
the target structure which I'm lookin for like below...(for 2 Child_ItemsInfo from my input structure)
1.Z1ABCD (Item_1 info)
2.Z1ABCD (Item_2 info)
3.Z1ABCD (Item_3 info)
4.Z1ABCD (Item_1 info)
5.Z1ABCD (Item_2 info)
6.Z1ABCD (Item_3 info)
But my code generating the segments like below;
1.Z1ABCD (Item_1 info)
2.Z1ABCD (Item_1 info)
3.Z1ABCD (Item_2 info)
4.Z1ABCD (Item_2 info)
5.Z1ABCD (Item_3 info)
6.Z1ABCD (Item_3 info)

Edited by: esha nadh on Mar 9, 2011 9:14 PM

I am bit confused .
Why are you using this ...
remove context-->Split by value(each) --->CollapseContext
Do Direct assignment like below
even the context should not change . it shoule be default .,
Item_1 - > Z1ABCD
Item_2 - > Z1ABCD
Item_3 - > Z1ABCD
isnt it working fine ??????
actually it should ..
In your case .
IZ1ABCD for Item_1 coming together because . you Used removeContext So Both Item_1 comest together .. and then you doing transformation .. so the result are coming together...
Try Like Direct assignment . I hoping it should work fine

IDOC Segment missing when reaching to ECC

Hi,
This is file-to-IDOC scenario. When file is loaded XI is picking and creating IDOC with all segments as expected in XI, but when reached to ECC sytem main header and item segments are missing.
Refreshed cache, reloaded metadata in XI, did full system cache refresh but no luck.
Checked in ECC thru IDOC_INBOUND_ASYNCHRONOUS function module to create IDOC and it did create successfully with all segments.
Segments are missing only when coming from XI. We are in SAP ECC 6.0 & PI 7.0. IDOC I am using is DELVRY03

Hi Sriram,
Can you please check this note which disucss about the same issue:

Idoc Error - EDI: Syntax error in IDoc (segment cannot be identified)

Hi All,
have created a new reduced message type for our new vendor A/C group through BD53. Also done reqd config for sending the vendor master through this message type. .
I have created couple of vendors for testing with X01 with withholding tax functionality and when try to send these vendors , Idocs are getting failed .
When I create vendor without withholding tax functionality , idoc is getting posted succesfully . If create vendor with entries in the feild whih are related to withholding tax . Idocs are getting failed .
If I see the status in WE05 ,Idocs which are posted succefully are showing the basic type as CREMAS03 . For idocs which are getting failed have the basic type as CREMAS04 and also the extension as Z1CREMAS . I don`t understand why the system is defaulting CREMA04 & Z1CREMAS when I send the vendor master with withholding tax feild entries.
I am not much familiar with ALE /Idoc set up. Please can any body help me to resolve the issue.
The error message in we05 as below
EDI: Syntax error in IDoc (segment cannot be identified)
Message no. E0078
Diagnosis
The segment Z1LFA1M does not occur at the current level of the basic type CREMAS04 (extension Z1CREMAS).
This error can have several reasons:
The segment Z1LFA1M is assigned to a group whose header segment does not occur.
The segment Z1LFA1M does not exist in the syntax description of the basic type CREMAS04 (extension Z1CREMAS).
The sequence of segments in the group in which the segment appears is incorrect.
Previous errors ('mandatory' segment or group missing) may be due to this error.
Procedure
Please check the IDoc or the syntax description of the basic type CREMAS04 (extension Z1CREMAS).
Thanks

Hi,
I don`t understand what do you mean release after adding segment.
Message type works i.e. Idoc get posted if I send with the vendor w/o withholding tax field entries. Idoc fails when send vendor with withholding tax field entry.

Replaced value is not getting relected in IDOC segment field

Hi,
Need your help for the below issue.
I am replacing the PO # with Delivery Doc # . But the replaced value is not getting reflected in the IDOC segment field(e1bp2017_gm_item_create-po_number.).
Function Module which I am using is IDOC_INPUT_MBGMCR as a copy.
Here is my code given below:
SELECT
            SINGLE vbeln
              INTO lx_vbeln
              FROM lips
             WHERE vgbel EQ e1bp2017_gm_item_create-po_number.
Move lx_vbeln TO e1bp2017_gm_item_create-po_number.
MOVE-CORRESPONDING e1bp2017_gm_item_create
               TO goodsmvt_item.
Then this is passed as TABLE in "BAPI_GOODSMVT_CREATE".
Please do the needful.

Hi Dheepa,
Check it in debug whether the filed is empty or having po#, when ur code is executed for the replacement. if it is empty, po# is populated after ur code. in this case you need to write the code in suitable place.

IDOC to JDBC scenario in case of Cost Element Group IDOC.

This is an IDOC to JDBC scenario.
The Cost Element Group IDOC is having different segments. The main segment E1COGH (1...unbound) is consisting of different subsegment like E1OGS (0...unbound) & E1COGV (0...unbound). The main segment (E1COGH) along with subsegments E1OGS & E1COGV) is occuring more that 1 times. I have to insert data into the table, which we can do in single rows (no hierarchy is possible in tables). I have used "use one as many" in message mapping. Now if E1OGS or E1COGV is repeating in a single E1COGH segment then we dont get any error. But if I duplicate the main segment then I am getting runtime exception.
Please suggest about how to map in this case.

In my scenario:
     E1COGH
     |
      -> E1COGS
         E1COGV
where     E1CGH -> Main segment
     E1COGS & E1COGV -> sub segment
E1COGH -> 1..unbound
E1COGS -> 1..unbound
E1COGV -> 1..unbound
At the target side I have created two Statement Structure (ie.Statement & Statement_1) . One for E1COGS (ie. Statement) & the other for E1COGV (ie. Statement_1).
Case 1 -> If E1COGS is present in the main segment E1COGH then it is mapped AS IS.
Case 2 -> If E1COGS is not present in the main segment E1COGH then it is mapped as blank.
This will be mapped with Statement & in the absence of E1COGS this Statement structure is SUPPRESSED.
Similarly,
Case 1 -> If E1COGV is present in the main segment E1COGH then it is mapped AS IS.
Case 2 -> If E1COGV is not present in the main segment E1COGH then it is mapped as blank.
This will be mapped with Statement_1 & in the absence of E1COGV this Statement_1 structure is SUPPRESSED.
All the elements of the segment E1COGH, E1COGHT & E1COGHR are replicated in all the rows for X (no. of occurance of E1COGS) + Y (no. of occurance of E1COGV).
While testing in Message Mapping, I am able to get the output as for multiple occurence of E1COGS & E1COGV in a single E1COGH.
But if I increse the occurence of E1COGH the it is giving the following error :
Runtime exception during processing target field mapping /ns0:MT_Cost_Element_Group_Response/Statement/DBtablename/access/GROUPNAME. The message is: Exception:[com.sap.aii.mappingtool.tf3.IllegalInstanceException: Too few values in first queue in function useOneAsMany. It must have the same number of contexts as second queue.] in class com.sap.aii.mappingtool.flib3.NodeFunctions method useOneAsMany[com.sap.aii.mappingtool.flib3.CollapseContexts@51197231, , ]
Please suggest how to map the occurence of E1COGH simultaneously with the occurence of E1COGS & E1COGV.

IDOC-Segment Created a idoc document against Billing document

Dear All,
Thanks in advance.
Already created a idoc document against Billing document and one of the IDOC segment is not in the IDOC document output segments(WE05) actually it missed the segment.
so i want to add the segment which it was missed during generation of IDOC document against billing document.
Example:
a) IDOC document misses one segment let suppose "Seg1".
b) In "Seg1" it have only one field let suppose "Field1".
c) But "Field1" does not have any value while generation of IDOC document so it doesn't create the respective segment in IDOC document.
d) so here, i want to edit the IDOC document to add the "Seg1" in the IDOC document and reprocessing the IDOC document.
Please help on this issue.
Regards,
Sridhar.

Hello,
          If your requirement is to have the Segment even with only 1 Field, you'll have to create an Idoc Extension in WE30.
         In order to populate the Custom Segment, Use the Customer Function '002' in the IDOC_OUTPUT_INVOIC which is EXIT_SAPLVEDF_002 where you can actually insert the Segment as a Child Segment of an Appropriate Segment.
        You can go for Custom segment with the IDoc Extension so that you dont have to manually insert the Segment again and again while reprocessing it.
Thanks and Regards,

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,
Navin

Hi 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.

Issue in extending Idoc

Hi Experts,
I am having one issue in extending standard idoc type.
I am extending basic type HRMD_A07.
Now issue is this idoc type was already being extended with
segment Z1P0009.
I tried to add my new field IBAN but as version non compatibility i
had to generate new version of this segment.
Now everthing is working fine but only me new field is getting
populated in the idoc and all old fileds from this
segment are not coming.
Please guide me in this regards.

Could you please elaborate more?
Did you create a new extension while extending basic type HRMD_A07? or change an existing extension? Also what is your SAP version? Is your old version of IDOC before upgrade?

Idoc segment release

Hi,
I wish to change one of the field's length in an idoc segment. It doesn't allow me to change it as the version is already released.
However, I cannot cancel the release too, as the released version belongs to an earlier version of SAP (4.7).
The current/existing version of the segment is of release 620. The current release is 710, so no change seems to be possible.
I can't create another version too, as it doesn't allow change of the earlier field definitions.
Could someone pls help.
Thanks!
Arthi

Hi,
We have similar issue. In the ORDERS05 IDOC, we had made changes to the segment E1EDP19 to repeat 99 times. Then IDOC extension ZORDERS05 was created. Due to new enhancement pack, the attributes of E1EDP19 were changed to repeat 5 times as per standard SAP.
This did not work for us because segment E1EDP19 should repeat 99 times. So we ran program to update the attributes of this segment. Now E1EDP19 can repeat 99 times.
But when we are processing ZORDERS05, the chagnes are not reflected. The reason could be, even though E1EDP19 was changed, it will not reflect in IDOC extension. For this to reflect, we are trying to cancel release ZORDERS05 once and release again.
I am not able to do this activity. Any pointers to this will be helpful. My requirement is to just cancel release once and release it again. Also while doing so, SAP message pointed me to 844899.
Regards,
Shahu
