Deltas for master data

Hi,
Will you please let me know the proceedure for master data delta set up.is it something, after init the delata gets activated automatically or do we need to set it in r/3 side(Where checking the check box ('delta enable')for a data source or is it something there are some specific data sources which will support delta.
Please let me know the proceedure for this, or if you have any docs or links please give me those.
Thanks & Regards,
Shashikanth.

BW - Delta for Master data not loading

Hello All,
I am not able to load delta for master data of vendor and material.
The initial load works fine but when I load delta it gives an error
" The extraction program does not support object 0vendor"
" ALE change pointers are not set up correctly"
Do i need to activate the change pointer in BD61. I was not sure so checking up with all experts.
Regards
Vanya

Hi Ravi,
We faced the same problem as you for 0MATERIAL_ATTR and we solved it by the following steps,
1. Delete the previous Delta Init for the InfoObject
If you have access to R/3 Side you can follow the steps or you can follow the BW Steps
Goto RSA7 ->Select and Delete the Init for the InfoObject
From BW Side
InfoPackage-> Inti for Source System -> Select & Delete
2. Execute the Init InfoPackage for the InfoPackage again.
3. After successful completion, execute the delta InfoPackage.
We have have got resolved by doing these steps and it may help for your problem as well.

Generic delta for master data

Hi All,
I am trying to create a generic delta for master data "equipment" . table in SASP is "EQUI". I am choosing ALE delta . in that I have to provide table name and "changed doc object' . when I give "equi" as table name and "aedat" (changed on ) as "changed doc object' -
it is throwing error.
also when I tried for time satmp /calday delta , the delta doesnot work when changeed are done. don't know why?
Any idea what has to be given in these fields.
Regards,
Dola

Hello,
TCDOB is a table where you need to maintain entries for Generic Detla.
Please goto SE16 : enter table name TCDOB
In the selection Screen Enter Object as EQUI and check the Number Of Entries..
I guess you need to maintain the number of fields on which the change is dependent for Detla ()
I treid creating the same Datasource Using Ale Detla
It worked and saved without errors :
i have the following entries in TCDOB table
OBJECT          TABNAME
EQUI            EQKT
EQUI            EQUI
EQUI            EQUZ
EQUI            FLEET
EQUI            ILOA
Please tell me your count and entries..
so that we can discuss this Further
Also if you find if there are no entries then you can Go to SCDO tcode and maintain entries with respect to change object.
waiting for your feedback

Managing Delta for Master Data

Hi Experts,
I'm facing a strange issue I would like to share with you.
I'm loading Master Data with DBConnect. The Delta is generated from a non-SAP source system and stored into my PSA.
My DTPs between Datasources and MD are in 'Delta' mode. Therefore, when refreshing, we should load only the new PSA Request containing the delta records... but it's not working everytime.
For some objects, it loads all PSA (ones already loaded + New delta request). I can't identify why, since it works for some other records without any problem.
I'm in SPS13.
If you have an idea, I would be quite gratefull.
Regards
Sylvain PERLA

OK, let's plan an upgrade.
Thanks

Generic delta for master data table MEAN

Hello all,
How should the settings for my generic data source look?
It's masterdata attributes and I'd like it to be delta compatible. The basis for the data source is table MEAN in R/3.
Could someone please specify the settings that should be applied in SBIW (Should for example a numeric pointer be used or is the date better for handling of the delta queue? How should the security ranges be set etc.?)?
Thanks,
Fredrik

About delta loading for master data attribute

Hi all,
We have a master data attribute loading failed which is a delta loading. I have to fix this problem but I have two questions:
1. how can I find the those delta requests because I need to delete all these failed requests first, am I right ? Master data is not like cube or ods that we can find the requests in Manage, for master data how can we find them ?
2. Could you please let me know the detailed procedures to perform this delta loading again ?
Thanks a lot

Hi...
1. how can I find the those delta requests because I need to delete all these failed requests first, am I right ? Master data is not like cube or ods that we can find the requests in Manage, for master data how can we find them ?
Look.....for master data.....no need to delete request from the target..........just make the status red.......and repeat the load.....But problem is that master data sometimes does'nt support Repeat delta..........if u repeat......then load will again fail with Update mode R.........in that case u hav to do re-init.......
1) delete the init flag.......(In the IP scheduler >> in the top Scheduler tab >> Initialization option for source system)
2) Init with data transfer(if failed load picks some records)..........otherwise .....init without data transfer.....if the last delta failed picking 0 records.......
3) then Delta.......
2. Could you please let me know the detailed procedures to perform this delta loading again ?
1) Make the QM status red.........to set back the init pointer.......
2) Repeat the load.....
After that.........if again load failed with Update mode R.....
1) delete the init flag.......
2) Init with data transfer(if failed load picks some records)..........otherwise init without data transfer.....
3) then Delta.......

Is there settng source system level for master data delta loading perfo

Hi Viwers,
Good Morning,
I am loading data from the source to target level for Master data it is taking too much time,I would like to know the how to increase the master data delta loading performance.
I would like to know the source system level is there any setting requited & target system level also.
Please give your inputs..........
Thanks & Regards,
Venkat Vanarasi.

Venkat -
Are u deleting the indexes of data target before delta loading ? If not,delete the indexes of data target before delta loading and recreate them after delta loading is done.This procedure increase load performance.You can perform whole procedure in process chain.

REPEAT DELTA WILL WORK FOR MASTER DATA DELTA LOADS

Hi Guru's,
REPEAT DELTA WILL WORK FOR MASTER DATA DELTA LOADS?
AS I AM NEW TO SAP-BI CAN ANY ONE GIVE THE DETAIL EXPLANATION ON IT.
IT WILL BE GREAT AND HELPFULL.
Thanks and Regards,
CM

Hi CM,
yes you can perform the repeat delta even for the master data if the datasource which was supplying the data was delta capable.
You can do the repeat delta only in case if your previous request was erroneous and dont forget to make the request red in the status,so that system will treat like you are requesting the failed request once again where in case you will miss the previous request, i,e erroneous request if you dont make the request red.
when you make the request red manually in the status,the pointer will move to the previous request once again in the delta queue and there will be no chance of missing the delta records.
This process was same for both transaction as well as master data.

Sunil...

When to set delta index flag for master data?

In transaction RSDDBIAMON2 option "Set Delta Flag" shows:
Table Name                     |Table Size          |Delta Index
/BIC/FTSGCSGMC          |10,155,000          |check mark in box
/BIC/DTSGCSGM1           |5,000,000           |check mark in box
/BI0/SVERSION               |700                    |check mark in box
When should I check the "Delta Index" column for fact, dimension, and master tables? I believe I need to check fact and dimension tables for delta BIA to occur during roll up so users can see the newly loaded requests but I am uncertain on when and why I should check this box for master data.
Thanks for your input.

Vitaliy,
Thanks for answering another of my question. Yes, we load master data a couple of times a day so based on your answer, I should also check box "Delta Index" for the master tables as well. Thanks for helping me understand this point.
If the below is our approach, #2 should be checked for all tables, correct?
1) Create/fill BIA index for cube "A"
2) Check the box "Delta Index" for all the tables which includes fact, dimension, and master tables for cube "A" .
3) Run process chain to roll up cube "A" daily
4) Run process chain to merge cube "A" weekly
Many thanks,
Thao

Delta enabled master data - Deletion of data sets

Hello,
is it possible to automatically delete a certain data set of a master data bearing InfoObject which is delta enabled ? Does a delta load for master data InfoObjects allow to fully delete a certain data set?
Example:
Delta Master InfoObject: Z_Test
Attributes: Z_Name, Z_Region, ....
Data sets:
(1) 12345, Name1, Region1, ....
(2) 23456, Name2, Region2, .... (this data set should be completely deleted)
(3) 34567, Name3, Region3, ...
Expected result:
(1) 12345
(2) 34567
I just want to know whether the deletion can be performed through a delta data load or not?
Thanks in Advance.
Marco

Hi Marco,
Welcome to SDN!!
You can goto RSA1 -> Info-object -> maintain master data and delete the unwanted records and loads the ones you need. If the no. of records are more then you may need to write an ABAP program. But before all this deletion make sure the master data is not used in any other Data target.

Extractors/ Setup Tables for Master Data

Hi Experts,
I am not sure if the extractor enhancement methods, setup table initialisation for Master Data different from transaction data.
I am trying to do a delta init with initialisation of Setup table (OLI7BW) for 0CUSTOMER_ATTR. And I am not able to see any records in RSA7. Althought RSA3 shows 10 data packets and 1000 records.
What does that mean.
What I want to achieve is all the records a fresh for a few master data datasources since they were refreshed last month. Since then they were not being used.
Kindly help me as soon as possible.
Thanks in advance.

Hi Priya,
I am not sure if the extractor enhancement methods, setup table initialisation for Master Data different from transaction data. -
For your information there is no conecpt of intialisation for master data.
I am trying to do a delta init with initialisation of Setup table (OLI7BW) for 0CUSTOMER_ATTR. And I am not able to see any records in RSA7. Althought RSA3 shows 10 data packets and 1000 records.
What does that mean.
As said there will be no setup tbale concepts for masterdata, the changes for masterdata follows the delta pointer concept(i.e whenever changes to standard masterdata table happens the message class trigger the delta pointer for those changed records and post in RSA7).So always u see in RSA7 the changed records for masterdata tables
What I want to achieve is all the records a fresh for a few master data datasources since they were refreshed last month. Since then they were not being used.
i didn't get abt this question can u eloborate
let me know if i answered ur queries

DTP for Master data

Hi Guys,
How to extract master data and hierarchies from ECC into BI infoobjects?
Do we follow the same procedure for loading master/hierarchy data as for transaction data - i.e. Load into PSA and then create Transformations and DTPs to load into infoobjects? If so, what is the best approach as far as Full/Delta loads.
1. Is it ok to do a full load into PSA (using infopackage) and then do a full load always (The process chains for master data would be running nightly).
or
2. Should we have 2 infopackages (full and delta) into PSA and then multiple DTPs. (The process chains for master data would be running nightly).
Regards.

Indicator: Only Get Delta Once
Source requests of a DTP for which this indicator is set are only transferred once, even if the DTP request is deleted in the target.
Use
If this indicator is set for a delta DTP, a snapshot scenario is built.
A scenario of this type may be required if you always want an InfoProvider to contain the most up-to-date dataset for a query but the DataSource on which it is based cannot deliver a delta (new, changed or deleted data records) for technical reasons. For this type of DataSource, the current dataset for the required selection can only be transferred using a 'full update'.
In this case, a DataStore object cannot usually be used to determine the missing delta information (overwrite and creation of delta). If this is not logically possible because, for example, data is deleted in the source without delivering reverse records, you can set this indicator and perform a snapshot scenario. Only the most up-to-date request for the DataSource is retained in the InfoProvider. Earlier requests for the DataSource are deleted from the (target) InfoProvider before a new one is requested (this is done by a process in a process chain, for example). They are not transferred again during the DTP delta process. When the system determines the delta when a new DTP is generated, these earlier (source) requests are seen as 'already fetched'.
Setting this indicator ensures that the content of the InfoProvider is an exact representation of the source data.
Dependencies
Requests that need to be fetched appear with this indicator in the where-used list of the PSA request, even is they have been deleted. Instead of a traffic light you have a delete indicator.
Get Data by Request
This indicator belongs to a DTP that gets data from a DataSource or InfoPackage in delta mode.
Use
If you set this indicator, a DTP request only gets data from an individual request in the source.
This is necessary, for example, if the dataset in the source is too large to be transferred to the target in a single request.
Dependencies
If you set this indicator, note that there is a risk of a backlog: If the source receives new requests faster than the DTP can fetch them, the amount of source requests to be transferred will increase steadily.

Unable to generate "Export data source" for Master data infoobject

Hi Gurus,
I'm in BW 3.5
I need to generate "Export data source" for a master data info object.
I followed below steps:
I ticked the checkbox "Characterist. is export data source" in the master data Info object maintenance screen.
In the Infosource area, for the desired Infoobject --> Right click --> Generate export datasource --> a dialog box displays saying "The generation of DataSource was successful"
Problem:
Even after refreshing, etc.. I couldn't find the generated datasource 8**** for the above master data. I also tried to replicate the datasource from the myself source system, but couldn't find it even there. I don't know where the generated export data source is hiding ???
Could anyone please help ????
Thanks,
Venkat

Hi Venkat,
I guess that after creating an export datasource for infoobject this DS should appear in the RSA1-Source systems - MYSELF - datasource overview (with name starting with 8). Since it's a datamart, it should appear also as system generated infosource. And in this case you would be able to assign in URs of data target the appropriate infosource (make sure that in Infoproviders tab of RSA1 you have inserted your infoobject as a data target).
However, there are some bugs related to export data source. CHeck if you see you export data source in RSA6.
If you don't see it - consider applying OSS Note #816892 - "30BSP26: Export DS for master data is not generated".
Note #876845 - "30BSP29: InfoObject change: Export DataSource not adjusted" is also may be useful.

Error while creating Data Source for master data attributes

Hi BI Experts,
Well its been some time for me that I have been part of Extraction in BI.I primarily handled reporting in my last assignments.
I was trying extraction with flat files in SAP BI 7(new to sap bi 7 but very much familiar with BW3.5) but failed in the activity during master data attributes and text upload in infoobject (say IOSP_Mat).
Here is the procedure that I did after creation of characteristic IOSP_Mat.I created a source system for flat file followed by data source for Master data attributes, i selected all the parameters correctly.i.e. csv file format, data seperator as ,
and other settings, now when i am trying to look at the proposed data in the next tab using Load example data.its not showing the desired result.The columns that I have maintained in Flat File is MAT_NUMBER and MAT_NAME (with say 100 data in the file)
same is the result when I am trying to load the text data too columns maintained are
(LANGUAGE MAT_NUMBER Short Description)(same 100 data).
now i used to rsa1old transaction to upload the file using 3.5 version.i created info source for master data/text/hierarchies for IOSP_Mat
now when trying to upload it using info package for master and text data,I observe its(the data) not maintained in the characteristic IOSP_Mat.
When I monitored ,I figured the data has not been even uploaded to the PSA level.
Can you BI experts tell me the answer for this.
Thanks,
Srijith

apologies to all of you for late response,
was busy with some other activities.
I don't remember the exact message,but I remember it was not loaded to even the PSA level.I will try it again and post the exact message.
Thanks again for your quick response.
Once again sorry to all of you for my late response
Thanks,
Sri

Creation of OLAP Variable for Master data

Dear BW Experts,
How to Create OLAP Variable for Master data in SAP BW? What is the use of OLAP Variable?

The entry column Type (Variable) on the Select Data tabpage indicates a variable time frame in which the data should be requested. The variables are not replaced by concrete values until a request is made. There are eight options:
Variable Data request Description
0
 Yesterday
 (12am 12am)
1
 Last week
 (Monday-Sunday)
2
 Last month
 (1. (First day - last day of previous month)
3
 Last quarter
 (1. (First day - last day of previous quarter)
4
 Last year
 (01. (January 1 Dec 31 of previous year)
5
 User time selection
 See below
6
 ABAP routines
 See below
7
 OLAP variables
 See below
Time selections with the help of the variables 0 to 4.
The variables 0-4 only refer to date fields of the data type DATS.
User time selection
Type 5 gives you a free selection of all fields.
If you select this variable for a field, confirm the selection, and then choose Detail for Type, an additional dialog box appears. In this dialog box you can freely limit the values of the fields and determine the next period value and the number of periods until a repetition.
Variables are placeholders for values and are not replaced by concrete values until a data request is made. You can also use a Variable for selections when requesting data for an InfoObject, if you choose type 7, confirm the selection, and then choose Detail for Type.
