Change communication structure for master data with direct update

Hi All,
I am having a problem with a change I want to make to some master data. I have added the attribute to the characteristic, but when I have gone to change the communication structure, its not possible (the add line button is greyed out)
I can see the new infoobject in the datasource/trans structure, but not in the comms structure (And yes it is in change mode ).
The master data uses direct update, and I have read that this causes some hassles in changing the comms str.
Can someone please give me some steps in doing this??
Thanks
Ryan

Hi Ryan,
Why u have nothing to map is ?
U r datasource trasfer structure from the source ssytem has nothing new ..
1)TO ur Info object u can only write the routing or give any formula or anythign like the trasfer rules oftions that have when u click on the IO icon..
2) Enhave the structure of the datasoruce that is getting from the R3 source system...
3) Replicate it ..
Then only u will be able to find the extra field at the Trasfer structure... to map to the IO which have been added..
hope it helps

Error handling for master data with direct update

Hi guys,
For master data with flexible update, error handling can be defined in InfoPackege, and if the load is performed via PSA there are several options - clear so far. But what about direct update...
But my specific question is: If an erroneous record (e.g invalid characters) occur in a master data load using direct update, this will set the request to red. But what does this mean in terms of what happens to the other records of the request (which are correct) are they written to the master data tables, so that they can be present once the masterdata is activated, or are nothing written to masterdata tables if a single record is erroneous???
Many thanks,
/ Christian

Hi Christian -
Difference between flexible upload & Direct upload is that direct upload does not have Update Rules, direct upload will have PSA as usual & you can do testing in PSA.
second part when you load master data - if error occurs all the records for that request no will be status error so activation will not have any impact on it i.e. no new records from failed load will be available.
hope it helps

Change comapny code for master data directly.

As per the requirement i need to change the company code for some records for company consolidation.
I need to convert three company codes with one comapny code.
Is it possible or there is any work arround. answers will be rewarded.

Probably not the answer you are looking for but SAP has [SLO|http://www.sap.com/services/bysubject/consulting/brochures/index.epx?PageSize=10&ActualPage=4] (System Landscape Optimization) consulting services. This service is used by SAP customers when they need to change data (master data/transactional data) during say a company consolidation.
Changing data in SAP tables directly is obviously highly discouraged, especially in a productive system.

After attribute load, did you activate your master data? Everytime you load master data, you have to activate it to see the new data.
Ok - Do the following:
RSA1-> Find you InfoObject-> right click and click on 'Activate Master Data'.
OR
If you want to activate all master data in one shot, goto RSA1->tools->Apply Hierarchy/Attribute change->Execute
Now check the data, you will be able to see all the loaded master data.

Loading Master Data with Flexible Update

Hi,
I have created an Infoobject - Business Partner (Master Data bearing characteristics). The attributes to this are Region, Sales Person, Industry code which are master bearing characteristic as well.
I need to load data to the business partner from a csv file.
The layout of the CSV file is -
BP number, BP text (long Text), Region Code, Region Desc (Med Text), Sales Person Code, Sales Person Desc (Med Text), Industry Code, Industry description (Med Text).
How do I define the infosource to load this data.
Appreciate any help with this.
Thank You,
Prashanth

Hi,
First of all, I need to note that there are two kind of Infosources: with direct and flexible update.
If you choose a direct IS, then in the creating of the IS you just enter the name of the infoobject where you are going to load data. The system will create a IS (comm. structure). Enter this IS for changing. The system will propose you the communication structure, click on a bottom icon Transfer structure/Transfer rules, choose as a Source system your flat file system. Agree with the system when it asks you to save assignments (up to 3 times). Activate TRs. Then click in the field for Datasource. You may see there another datasources (for texts, attributes and hierarchies). Choose one by one another datasources with their activation.
Now you can create an infopackage for a load you can choose what kind of package it is going to be for loading texts, attributes or hierarchies.
Note that in this case the structure of the flat file is proposed by the system and you need just prepare the flat file corresponding to the proposed structure (different for each of 3 possible datasources). Execute infopackage.
If you use a flexible IS, then you may insert into comm. structure the fields that you think you may need in the master data. Note that here you may have not only attributes but TEXTS also. Save a comm. structure. Assign a flat file source system and activate a TRs.
After that in RSA1-dataproviders tab right click insert IO as a data target choose your IO. Refresh the screen. Youll see up to three data targets. Create update rules for each of them. In URs map the fields in the IS with the fields in URs.

Is it possible to make a delta load for a Master data with Standard DS

I have a full load bringing huge data for master data with standard datasource.
I want to run a delta due to huge no. of records but when I create a new Infopackage it dont give a option for delta update.
Are delta loads specific to only standard or customized DS's or any other reason behind that ?

I kind of understand what you are asking about, but I am unclear as to how it pertains to our BO SDK.
You are wanting to find the differences between a large dataset and another large dataset.
I am not sure what an Infopackage is.
Are you using the BO Enterprise SDK or some other product?

Data Source creation for Master Data from Flat File to BW

Hi,
I need to upload Master Data from Flat File. Can anybody tell step by step right from begining of creation of DataSource up to Loading into Master Data InfoObject.
can any body have Document.
Regards,
Chakri.

Hi,
This is the procedure.
1. Create m-data with or without attributes.
2. Create infosource .
    a) with flexible update
         or
    b) with direct update
3. Create transfer rules and assign tyhe names of m-data and attribute in "Transfer rules" tab and transfer them to communication structure.
4. Create the flat-file with same stucture as communication structure.
5. if chosen direct update then create infopackage and assign the name of flat-file and schedule it.
6. if chosen flexible update the create update rule with assigning name of the infosource and the schedule it by creating infopackage.
Hope this helps. If still have prob then let me know.
Follow this link also.

A question on DataSource for Master Data example 0plant,0customer etc...,

I can get the field names of a standard data source for master data (say for example 0plant_attr) using table ROOSFIELD .
Now i want to know from which tables these fields are coming from.
How to get the table name for a each field in standard data source for master data .
For transaction data, transaction LBWE is there,similarly is there something like this for master data.
Another Question:
How to see communication structure for standard data source for master data ?

Hi,
the entire documentation for standard things in bi is avaialable in business content of net weavers in help.sap.com..... please refer this for any standard thing the entire documentation will be available.....

Open Transactions in ECC for Master Data changes in MDM

Hi All,
I have a basic Design question on how to handle the impact of Data changes in MDM for any open transactions with that Master object. For eg if we have a Material set up in MDM and in ECC and there are open Purchase Orders for that Material, now if the Base Unit of Measure is changed in MDM and gets harmonized to ECC(After Workflow approval of the Change) how will it impact the PO attached to the material . Can we do any configuration in ECC that will restrict any Open PO s not to take the new changed value and any new POs taking up the new Base Unit of Measure , or can we set up an alert/notification that will trigger for a PO whenever any Master Data is changed and the PO takes the new changed value on the fly . What will be the best approach from a solution point of view .
Thanks ,
Prabuddha

Hi Prabuddha,
In ECC if a change happens to a master data not all the changes are reflected automatically in the open documents like open PO or open Sales order. Some fields values have to be redetermined for eg: "pricing procedure", some of them needs to be changed manually for eg: "Description". Moreover specific to your eg of Base unit of measure, this is a sensitive field and has lot of impact on the process so there for changing such fields it is necessary to close all the open documents against the Master data record in consideration. This fact is regardless whether the change happens through an IDoc or directly by MM02/XK02/XD02
Prabudha, Please revert if you have further questions.
Best Regards

Why to use chnage pointers for master data idoc why not the change idoc

Hi Gurus,
I have one doubt about Idoc.
When changes to master data has to be sent Change pointers are configured and used. (CDPOS & CDHDR). In case of the transaction data change change idoc is used as is the case with orders (we use ORDCHG for ORDERS message type to send the chnage details to a order which was already sent to other system.
Why we can't use change idoc or message type whatever, instead of Chnage pointers in case of master data or vice versa in case of transaction data.
Your valuable input will be rewarded with suitable points!!
-B S B.

Hi,
It was a good question ... SAP seems never designed the change pointer to handle transactional data IDocs. Only for master data IDocs distribution purposes.
It may due to volume data ... the transactional data can change many times within a day compare with master data which hardly change or once a while.

Characteristics - Master data Tab- infosource with direct update

Dear Experts,
Please explain me in Laymans Language as i am new to BI (but am an ABAP consultant).
In Info Object Characteristics, Master data Tab there is infosource with direct update with an application Component.
1. Now my doubt is, when i specify the Application Component, this infosource would appear under the application component in Modeling->Infosources.
Then on this infosource i would right click and create the info pakage and then data transfer process.
is it correct?
2. Suppose for this characteristic if i dont specify the infosource with direct update then it wont appear in the infosource, so how can i load data in this case?
Regards
BI Learner

Hi,
Using an InfoSource with direct updating, master data (characteristics with attributes, texts, or hierarchies) of an InfoObject can be updated directly (without update rules, only using transfer rules) into the master data table. To do this you must assign it an application component. The system displays the characteristic in the InfoSource tree in the Data Warehousing Workbench. You can assign DataSources and source systems to the characteristic from there. You can then also load master data, texts, and hierarchies for the characteristic.
You cannot use an InfoObject as an InfoSource with direct updating if:
i. The characteristic you want to modify is characteristic 0SOURSYSTEM (source system ID).
ii. The characteristic has neither master data nor texts nor hierarchies. It is therefore impossible to load data for the characteristic.
iii. The characteristic that you want to modify turns out not to be a characteristic, but a unit or a key figure.
To generate an export DataSource for a characteristic, the characteristic must also be an InfoSource with direct updating.
1. *Now my doubt is, when i specify the Application Component, this infosource would appear under the application component in Modeling->Infosources.
Then on this infosource i would right click and create the info pakage and then data transfer process.*
The characteristic will be available in info source tree, you can assign a datasource->assignsource system->create package->load data.
2. Suppose for this characteristic if i dont specify the infosource with direct update then it wont appear in the infosource, so how can i load data in this case?
For a characteristic If you dont specify 'InfoSources with Direct Updating' then it wont appear in infosource tree.

Long DDIC Activation for Master Data Change During Transport

Good Morning Folks,
During transport of a change to a custom master data object to production, the data dictionary activation is taking a very long time and using a very large amount of space.
The change to the master data object was adding three additional navigational attributes. This master data is not time-dependant. The master data contains about 1.2 million records and has 49 active navigational attributes u2013 including the three new ones. The Data Dictionary activation is executing report SAPLRSDU for more than 8 hours and is using upwards of 52GB of temp filespace (of 92GB allocated) during this time. To the best of our knowledge, it looks as if it is trying to recreate or repopulate the /BIC/Pxxxx table of the master data. It looks like it's reading billions of records (probably the same 1.2 m records over and over.)
There are no errors in any logs that we can see.
Previous changes to this master data object have been successful, and reasonably fast. And the transport of this change from Dev to our QA environment was very fast.
We still need to get this change in, as well as additional changes that are dependant. Why would this take so long, and is there anything we can do to get this to run faster?
BTW: We are on 3.5 (but looking forward to NW7.)
Thanks, Brian

Brian,
Usually adding nav attributes would mean that the X and y tables get regenerated...
Also do you notice reads only on the P-Table or other tables which have this object as well..?
If it is only the P Table - try refreshing the stats for the same...

Online Change Transfer for Master Data

HI,
whats transaction for Online Change Transfer for Master Data, and how to use it.
regards
manish

Hi Manish ,
You make the settings for change transfers in transaction *CFC9 (Change Transfer
for Master Data setting)*
For material masters, customers and vendors, the change transfer can occur
periodically or can be executed online immediately. You also have the option of
deactivating the change transfer.
You can also configure an immediate change transfer for work centers and
resources. In this case, the change transfer only concerns the header data of the
individual work center capacities.
Hope it will help you.
