Classification DataSource Enhancement.

Hi,
I am enhancing a Classification DataSource to populate the multiple values by BADI. While doing so I am getting an error as c_t_data is unknown. Is the internal table for classification data source enhancements different from c_t_data ? How can I find out the internal table details ?
Regards,
Hitesh

Hi,
You can add the classification data in Classification datasource....In case you need more Classification data....the just identifiy the Object from AUSP and enhance accordingly.....no need to write any code for this.......
Also if you need any data other then Classification data......then enhance the base attribute datasource not the classification datasource.

Enhancing the Classification Datasources . Tcode - CTBW

Hi Guys,
we need to use customer exit for populating certaing classification field values in the Classification datasources ( tcode - CTBW).
could you please provide any document or info that whether it is possible to use the customer exit using CMOD for deriving the value for the calssification field.
Thanks
lnv.

Thank you for the document KJ, it was veryhelpful.
I just have one more question ?? When I generate the datasource in transaction CTBW it is only generating the text datasource, for example
1CL_AMIL010
1CL_AMIL011
1CL_AMIL012 and so on, but the datasource for attributes 1CL_OMAT001 is not being genereted, and i don't know why.
I'm using 0MATERIAL_ATTR as base datasource, cat class = 01, Table MARA.
do you know why this attr datasource 1CL_OMAT001 is not being generated ? The system ask me for a password of developer user, but i don't have one.

No key field found for creation of DataSource - Classification Datasource

Hello,
While trying to create a clasiffication datasource based on 0PLANT_ATTR, when i assign a characteristic and push the DataSource button, i get the following message:
No key field found for creation of DataSource
Diagnosis
During generation of a classification or configuration DataSource, only those key fields for the object table (field "Obj.Tabelle") that are already present in the basis DataSource transferred to the extract structure. This is the case when none of the key fields of the object table were found in the structure of the basis DataSource.
System response
A DataSource cannot be created without key fields. The action was cancelled.
Procedure
Check whether you have selected the correct basis DataSource and object table. For more information, please see SAP Note 569849.
Do you know what can be the problem?
Thank you and regards

Hi Alberto,
plants are a special case. The key which is used for the classification
of plants (object type BETR) is not the same as the key which is used in
datasource 0PLANT_ATTR.
BETR has key LOCNR (Site). That's a customer related to a plant. The
customer number will be extracted in field LOCNR.
0PLANT_ATTR extracts the plant in its key field WERKS.
Transaction CTBW and the generic extraction program for classifications
don't know the relationship between LOCNR and WERKS. So they cannot map
them.
I do recommend a solution which would add the mapping between
LOCNR and WERKS:
1. Create please the classification datasource as intended, but use
datasource 0RT_LOC_MGR_ATTR as basis datasource. It's the only
datasource of the content where LOCNR is a key field. So
0RT_LOC_MGR_ATTR is used as a dummy here, to allow transaction CTBW to
create the classification datasource. It's not necessary to extract
data with datasource 0RT_LOC_MGR_ATTR.
2. Extend please the extract structure of the created classification
datasource. Add please field WERKS using component type WERKS_D. Make
this field visible.
3. Fill field WERKS in the extractor user exit EXIT_SAPLRSAP_002. WERKS
can be read from table KNA1 by using the customer number extracted to
LOCNR to select on field KNA1-KUNNR.
4. Transaction CTBW_META on the BW system isn't able to append the
characteristics from the classification datasource to infosource
0PLANT, because the keys are different. So create please a new info
source with CTBW_META. This allows CTBW_META to create the info objects
for the characteristics used in the classification datasource.
5. Add please the characteristics used in the classification datasource
to infosource 0PLANT manually. You will find the info object names of
the characteristics by looking up the characteristic datasources which
are assigned to the classification datasource in transaction CTBW. From
these names you can derive the info object names:
1CL_A... -> C_A...
6. Disconnect the infosource which has been created with CTBW_META from
the classification datasource.
7. Connect please the classification datasource to infosource 0PLANT
Use following info object:
info object   field
0PLANT       WERKS
The info object names for the characteristics are explained in step 5.
8. Add an infopackage to infosource 0PLANT for the classification
datasource.
Now the extraction of classifications of sites should work.
Best regards,
Rolf
P.S. I saw the system messed it up and doesn't display any new and empty lines. Sorry, I hope you still can read it.

Field in Classification Datasource not getting populated

Hi all,
I created a classifiacation datasource 1CL_ODS_001 from the MCH1 Table. when checking this in RSA3, Data is not populating in classification datasource in the field LOBM_HSDAT, LOBM_LFDAT, LOBM_VFDAT etc.
How does data get populated in LOBM fields.
Do i have to make some changes for data to get populated in this field.
Help needed please.

Hi Vishnu,
Thanks for your response.
I followed the procedure described in this article.
"Step by Step Guide to Extract Batch Master Data via Generic and Classification Datasource to BW" http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/d0a8b9c1-dee5-2d10-feb5-9b0d54126782?quicklink=index&overridelayout=true
I created a datasource from the View and fromt that datasource i created a classification datasource.
I checked in RSA6, the hide field is not checked. Is there anything else that i can do to update the fields.

How to include key field in classification datasource?

Hello,
How can I include key fields in a new classification datasource?
When i try to generate my classification datasource i get this error:
No key field found for creation of DataSource
Diagnosis
During generation of a classification or configuration DataSource, only those key fields for the object table (field "Obj.Tabelle") that are already present in the basis DataSource transferred to the extract structure. This is the case when none of the key fields of the object table were found in the structure of the basis DataSource.
Hence the datasource does not get generated.
Thank you very much and regards.

Hello Prem,
Yes, the characteristisc are in the system. I also saved these charateristics, they are in N status at the moment.
The problem is when i click on Datasouce buttom to generate the datasource, this is when I get the error message i mention above.
I tried to do an example with 0MATERIAL_ATTR with obj. table MARA and class cat 001 and i had no problem.
Then i try to do it with 0PLANT_ATTR obj table BETR and class cat 030 and i get this key problem.
Can this be related to the fact that MARA table has got a key and BETR does not have one?
Thank you and Regards.

Creating BADI for datasource enhancement in CRM system

Hi,
I am working on SAP BI/BW. This is the first time I am working in CRM system with CRM datasources. Facing some problem for datasource enhancement as never done it before in the CRM system. Is there anyone who can help in in creating BADI for datasource enhancement in CRM.
Thanks in advance
Moumita

Hi Kushal,
You can find the BADI name by,
Go to Transaction SE24
Enter the Object Type CL_EXITHANDLER and click on Display.
Double Click on method "GET_INSTANCE".
Put a Break-point on Call method cl_exithandler=>get_class_name_by_interface
Run RSA3 transaction and execute the DataSource.
The execution will stop at the break point.
Check the values of variable 'exit_name', it will give you the BADI name called at that time.
Thanks,
Kokila

if you follow this 7 steps, you will find a suitable BADI.

Different ways to Datasource Enhancement

I know DS enhancement can be done through ABAP Statement CASE,ENDCASE,WHEN. I came to know that this is old technique to enhance the datasource as it makes the code quite messy if several developers work on the same code.
I came across one document on SDN where we create a new program for each datasource which is independent from other enhancement.
I just want to know how this program works and the difference between this technique and old technique as i have limited ABAP knowledge.
What are the exact challenges that we come across when we use CASE,ENDCASE,WHEN statements.
Edited by: Murali K on Jun 1, 2010 6:31 AM

Hi Murli,
1) Datasource enhancement previously was done using CMOD Still many organizatins continue with this approach.
Here you can get option to write code for your appended field in ur Standard datsource where you can write select statements etc.
2) Now SAP is recommending to Write Codes using BADI .this approach helps to maintain individual implementations for each data source enhancement
This methods advantage over previous CMOD method is that ,in CMOD a single include will contain all the ABAP coding (this will create problem in marinating the versions for developers).specially while you are transporting the CMOD code to test and prod systems.
With the new BADI method you can avoid this problem as individual implementations can be transported independently without creating conflicts.

Problems with classification datasource

Dear experts,
I need to assign a new char to a classification datasource. I have created de char in CT04 transaction, and then I have assigned this new char to the class in CL02 transaction.
At CTBW transaction I have assigned the new char, and then I push DataSource button to generate de datasource, but then a error messagge appears that indicate a char does not exist, but not the new char other. If I a review the class all chars are ok.
I have tried to save without the char of the error messagge and then the error indicate other char.
what can i do?
Thanks in advance.

Class selection in Material Classification Datasource

I need to extract material classification from R/3 to BW. For this I generated a 1CL* datasource in transaction CTBW. As part of the datasource configuration I selected the Class type (001 in this case) and the characteristic objects to be extracted (for example, COLOR, SIZE, etc.). I have an additional requirement that is to select the Class from which the characteristic value is to be read (R/3 configuration is so that the same characteristic can be part of several different classes. For example, SIZE can be part of 'Ingrediends materials' and 'Packaging materials' classes).
As far as I know, this is not possible because BW doesn't have the 'Class' level value for selection in the materia classification datasource, only the object level value. Is there a standard way to have the 'Class' filtered in the datasource generated with CTBW transaction?. Thank you.

We came to the conclussion that it is not necessary to worry about the Class when extracting data to BW. Although it is possible to have one characteristic included in several classes in R/3, when a value is assigned to a material, the value is unique. Check the assignment of those values is saved in table AUSP in R/3 where the class is not part of the key, only the Class Type. This means that one material code is going to have always only one value for the characteristic despite of the class/classes it is included in. So, don't have to worry about the class when extracting data to BW. Hope this helps.

Problem in datasource enhancement

Hi All,
Facing a problem in datasource enhancement.
In R/3 SAP ABAP release = 640 and
BW release = 350.
Datasource: 0WBS_ELEMT_ATTR
I enhanced the datasource by adding an append structure with 'ZZ' fields.The data elements for these fields are SAP standard (like KUNNR,VKORG etc...)
Everything's active and there are no inconsistencies.
However these added fields are not visible either in the RSA6 maintenance or in RSA3 checker.
Hence I am unable to replicate these fields and pull them over to BW.
Please advise.

Guys,
The problem is not with hiding/unhiding these fields.
The appended fields themselves are not coming up through the RSA6 maintenance. They are not available for unhiding.
Please advise.

Classification Datasources

Hello Gurus.
Can you explain me step by step how to create a classification datasource in transaction CTBW. I need to extract some material characteristics from R/3, the characteristics I need came from a function module named VC_I_GET_CONFIGURATION_IBASE. I don't know how to extract this characteristics into BW. Is it any standard datasoure that make this?
Which is the best solution to do it ???.
Please help me.
THANKS.

Thank you for the document KJ, it was veryhelpful.
I just have one more question ?? When I generate the datasource in transaction CTBW it is only generating the text datasource, for example
1CL_AMIL010
1CL_AMIL011
1CL_AMIL012 and so on, but the datasource for attributes 1CL_OMAT001 is not being genereted, and i don't know why.
I'm using 0MATERIAL_ATTR as base datasource, cat class = 01, Table MARA.
do you know why this attr datasource 1CL_OMAT001 is not being generated ? The system ask me for a password of developer user, but i don't have one.
