Maintaining attribut time dependent master data

Hi all,
I have a question regarding normal system behaviour while maintaining BW Attributs with dependent master data. For example, I have created an infoobject like this:
- cod 40029, class 10 valid from 01.01.2008 until 31.12.2008
- cod 40029, class 10 valid from 01.01.2009 until 31.12.9999
But afterwards when I try to maintain master data and change the 2nd row (valid until the end of 2010) the system changes the requested row but also creates an extra line with same data valid until 9999
- cod 40029, class 10 valid from 01.01.2008 until 31.12.2008
- cod 40029, class 10 valid from 01.01.2009 until 31.12.2010
- cod 40029, class 10 valid from 01.01.2011 until 31.12.9999 (extra line)
Is this the standard behaviour? the fact is that with this behaviour the user allways needs to "delete" the fields cod 40029 and classe 10 to make the row "unuseful".

Pedro

Hi Pedro,
Yes this is the standard behaviour.
I am not sure where you are using this and why you need to make it unuseful.
If you are using it in BPS or IP. Create one more attrbute to this master data object, this would flag the usefulness of the timeslice.
You would then be able to filtrer to only useful timeslices in your planning/reporting.
Dont forget to make the flag attribute as navigaitonal attribute.This will allow selection for the flag in the report or filters in IP or BPS.
Hope this helps,
Best regards,
Sunmit.

BPC - Time Dependent Master Data

Hi,
I wanted to confirm can we maintain time Dependent master data in BPC ?
For Example : For dimension employee I have "Date of compensation change" as an attribute.
Now for cycle it will have different value and for cycle 2 it will have different value.
Cycle 1 = Jan to Jun Cycle 2 Jun to Dec
For cycle the value is Jan 2008 for cycle 2 the value would be July 2008.
Will this overwrite the previous value or it can maintain different Master data for cycl1 and cycle 2?
Thanks
Ankita

Hi Ankita,
The current BPC release does not support time-dependant master data.

Time-dependent master data in the cube and query

Hello,
I have a time-dep. masterdata infoobject with two time-dep attributes (one of them is KF). If i add this infoobject into the cube, what time period SID will be considered during the load? I assume it only matters during load, if i add the KF to the query it gets its value based on the SID in the cube.. right?
Thanks,
vamsi.

If its Time Dependent Master Data object when you run your Master Data if that time any changes to the Master Data that value will be overwrite to the old value you will get the new value. When you run the Query execution the Infocube Master Data infoobject will having the SID that time it will to there it will be displayed at that moved what is the value you have in the Master Data table.
This is what my experience.

What is time dependent master data?

Can anybody explain me in detail with an example for time dependent master data?
Thanks in advance.
Sharat.

hi,
the master data value changes with respect to some time characteristics.
say- Salesregion is a char that have sales rep as master data(attribute)
saleregion date from date to              sales rep
sr001        20/10/2007 20/12/2007          Ram
sr002        21/12/2007 12/05/2008          Ram
in the above example Ram is in two sales region in different dates.
these type of attributes were time dependent.
usually time period will be defined in the data range of 01/01/1000 to 31/12/9999.

Modify code to pull the time dependent master data

I fully under stand the suggestion below for the requirement to add the time dependent attribute comp code
thanks fo rthe help but please tell me if there is a way i can modify the abap code and make the user enter the value for the date on which he want to pull th emaster data for company code or keydate to and from and pull the master data, so how will i proceede should i create the variable on 0doc_date and how to modify the code. please help . i have opened another question with same desc as above to assign points
thanks
soniya
The literal within <..> is supposed to be replaced by the actual field name (as I didn't know the fields). In this case, I am changing your code for costcenter/company-code.
data : wa like /bi0/qcostcenter.
select single * from /bi0/qcostcenter into wa
where costcenter = comm_structure-costcenter
and objvers = 'A'
and datefrom le comm_structure-<keydatefield>
and dateto ge comm_structure-<keydatefield>.
if sy-subrc = 0.
result = wa-comp_code.
endif.
abort = 0.
You can use this code for update rule of company_code. You have to replace '<keydatefield>' with a field name that contains the date on which the company is to be derived. If there is a date in your comm_structure (eg aedat) which you can use, you can specify that field in place of this literal (instead of comm_structure-<keydatefld> use comm_structure-aedat). If you have no such field, and you wish to use current date for getting the company code from time-dependent master data, you can use sy-datum (ie replace comm_strucutre-<keydatefld> with sy-datum).
And it should work.
The 'master data attribute' option is one of the options when you create update rule (one of the radio button options).

That the code is doing anyway.
If your txn data in the cube doesn't have a date, how does it know it is Feb data, or, it is March data?
If it has a date or month field, you should modify and use this code to update the company based on that date instead of system date.
Other than that minor variation, it is already doing what you look for.

Time Dependency Master Data Load

Hi:
This is my first time to work on time dependency master data. I need help!
I first deleted master data and cleaned up the PSA for material sales.
Then I have turned on the feature of time dependent on the info object for material sales. Save it and activated the object.
Then i have problems by loading the master sales attribute data in PSA. The error is: on every record of material, it has "invalid 'to' date '00/00/0000'" and "invalid 'from' data '00/00/0000'".
Is every process i did wrong? What is the process to work on time dependent master data? and loading the data?
Thank you!!

Hi,
After turning on the time dependence...you get an extra field in the key of the master data table Q table date to and a new field date from as a new field.
These two fields needs to be mapped to date to and date from R/3 source as well.
If there is no source field for these two then you need to make sure to get the values for these fields.
Just check if you are getting any field like that from R/3...right now i think you have left the mappings for these fields as blank.
Thanks

Reporting on Time Dependent Master Date Info Provider

Dear All.
We have a info object Employee which is time dependent master data containing all the information with time dependency, when i create the query over this info object it give me the option to select the key date and it show the accurate information which is lying according to the key date.
my requirement is to show all the records in the report which are there in master data but i am not able to show more then one record cause of the key date, can you please let me know how can i show all the records for any given employee id in the query.

Hello Zeeshan,
By standard if you create query directly on time dependent info object, it would display the active records as of the report execution (if no key date has been provided). In any case you can only see one record per the info object key, not the history.
In order to fulfill this requirement, you may need to create infoset on this infoobject and select "date from" and "date to" as part of infoset fields.
Then create bex query on the infoset and drag the "date from" and "date to" also into "rows" section of the query (apart from infoobject key, time dependent attributes). This will let you see the history of changes to time-dependent attributes of the infoobject.
Cheers,
Vasu

Reporting Need on Time-Dependent Master Data

Hi Gurus, I have asked this question earlier as well but I did not got satisfactory answer so I thought I should open another thread.
I have this time-dependent Master data infoobject. I see that from the 2 extra fields are added DATETO and DATEFROM. I see in the transfer structure that theyare mapped to ENDDA and BEGDA from an R/3 table.
At the reporting level, the InfoProvider doesn't show these 2 fields. I wanted to see how I can make them show up in the InfoProvider so that I can create report using them. Please help me out on this one. Please let me know if I need to clarify this more.
Thnx.

Hi Bigtoja,
Immediately I can suggest 2 options ...
1. Have these two fields as attributes of the info object ... this will make them appear on the info provider.
2. Have an infoset built on it which will act as an info provider.
Adn as far as your question goes ... What I am trying to figure out is ... does making an info object as an info provider exposes only the P table ... since P table will not have Date To and Date From? I will have to research as well ...
Best regards,
Kazmi

Time dependant master data

Hello,
We have Cost Center as a time-dependant master data attribute of 0Employee and a cube with the day and hours for employees such as below.
Time Cube
Employee#   Work Date          Hours
1             1/5/2008   8
1                 2/8/2008    8
Master Data
Employee#   Begin Date End Date Cost Center
1                 1/5/2008     1/31/2008 1000
1                 2/8/2008     12/31/9999 1200
If we run a query based on the above with a "Key Date" of 2/15/2008 we'll get the below:
Employee#    Work Date         Hours   Cost Center
1                  1/5/2008   8         1200
1                  2/8/2008   8         1200
However what we're really looking for is a design so that when the query is run it will look at the Work Day and join with the master data for that date range and use the cost center for that day, such as below. Is this possible?
Employee#     Work Date         Hours   Cost Center
1                   1/5/2008   8           1000
1                   2/8/2008   8           1200
Thanks,
Ron

One way to do this dynamically with no restrictions is to use virtual characteristic.
There is a BW Expert article on this: u201CVirtual Characteristics and Key Figures Make Queries More Dynamicu201D, here is the [link|http://www.bwexpertonline.com/archive/Volume_02_(2004)/Issue_02_(February)/V2I2A1.cfm?session=].

Changing time dependent master data records

Hello All,
I have a time dependent master data infoobject that has 39 million entries.
Now we decided that we no longer need it time dependent.
Hence we want to maintain constant value ( 01.01.1000 to 31.12.9999) going forward.(as changing the object's time dependency will have huge impact)
But for the historical data, we want to fix this and maintain only one record per value which will be the last record.
Can you please provide inputs on how this can be achieved as i tried various combinations of load( load to a copy object taking only last record, changing its valid to to 01.01.1000 and loading back) and its not working.
e.g the value XXX has following entries currently:
Object
Valid To
Valid From
XXX
15.06.2007
01.01.1000
XXX
19.09.2007
16.06.2007
XXX
28.01.2008
20.09.2007
XXX
30.03.2009
29.01.2008
XXX
31.03.2009
31.03.2009
XXX
15.04.2009
01.04.2009
XXX
31.12.9999
16.04.2009
we need to get to the below format:
Object
Valid To
Valid From
XXX
31.12.9999
01.01.1000

Hi Dhanya,
The approach u did (load to a copy object taking only last record, changing its valid to to 01.01.1000 and loading back) will not work on Master data because it is not a DSO, with the Proper keys in place, to overwrite all the previously existing data records. This approach will only work if the infoobject is not time dependent and in that case the question u posed will not arise at all .
SOLUTION:
One thing is Inevitable as Prashanth has prescribed, u have to delete the transaction data first at all the places, where and all it was used.
Then just delete the entire master data from the info object and just do a FULL DTP load from the underlying datasource putting a FILTER like "VALID_TO = 31.12.9999" so that only the last record of a particular Value will be loaded. (No need to do a full load from the source because even in the source it might had been the same old Values and might not have been revamped.)
Even for further delta's, it will be safer to maintain this filter at the DTP level if u r not sure of the constant value maintenance at the source.
Thanks & Regards

Activate time dependent master data

Hello,
we're experiencing problems in activating time dependent master data.
We're using 0UCINSTALLA infoobject, in the P table all records have objvers = A, but in the Q table there are only a few A records, the most of them have objvers = M and changed = I.
So, how can we activate those records?
Thanks,
Tudor

hi David,
I am having the same problem activating the 0mat_plant...
It is says that the object status is inactive & try to activate it...
The steps I did was....
Hi All,
I am adding a navigational attribute to 0mat_plant...
& after that when I am activating 0mat_plant, it throws an error as follows:
*Diagnosis:*Errors arose when activating InfoObject 0MAT_PLANT. An active version already existed before the activation.
_System Response:_InfoObject 0MAT_PLANT could not be reset to the old active version. Since the generated objects no longer correspond to the old active version, they were reset to inactive.
*Procedure:*The old active version of InfoObject 0MAT_PLANT can no longer be used. Remove the cause of the activation error and activate InfoObject 0MAT_PLANT anew.
Pls help me with this issue ASAP...

0CALDAY for time dependent master data lookup unknown when migrated to 7.0

I am in the process of migrating a number of InfoProviders from the 3.x Business Content to the new methodology for BI 2004s.
When I try to create a transformation from the Update Rules for 0PA_C01, all of the rules that use a master data lookup into 0EMPLOYEE give me the error such as "Rule 41 (target field: 0PERSON group: Standard Group): Time char. 0CALDAY in rule unknown".
How do I fix the transformation rule that is generated from the update rule for these time-dependent master data attributes?

Hi Mark,
look at http://www.service.sap.com/. I guess you need to implement some corrections or newer supp-packages.

DSO as a time dependent Master Data infoprovider

Hi All
I am looking for a "How To" document on how to use a DSO as a time dependent MD provider.
I want to load a non time dependent Master Data from a non SAP source and update the DSO daily.
When ever an attribute is changing, I want to update the last status "To Date" from 31.12.9999 to today.
Hope I am clear on this one.
I don't want to use regular master data capabilities...
Thanks, Dror

Jurgen is right...
For an after image based extractor containing the latest view of the world - you basically can do this
DSO 1
Customer - Key
Sales Persion
Date to
Date From
last_date = 31.12.9999 (constant)
load date = sy-datum
First load:
customer A, Sales Person X, To Date = 31.12.9999 , from date = 12.03.2010
Second load a week later
customer A, Sales Person Y, To Date = 31.12.9999 , from date = 19.03.2010
Change log generated is
customer A, Sales Person X, To Date = 31.12.9999 , from date = 12.03.2010 record mode before image
customer A, Sales Person Y, To Date = 31.12.9999 , from date = 19.03.2010 record mode after image
What you can do now is feed master data timedependant object or another dso.
If it is another DSO then the structure is this
DSO 2
Customer - Key
Date from - Key
Sales Persion
Date to
You need the date_from as part of the key because you are going to use the overwrite facility to play with the data depending on the record mode of the changelog entries
but in the start routine make sure the semantic keys are correct so you get both images in the same packet
Then use field symbols to load the data package in to sort and then find the opposing after image and before image then
if record mode = before image
To date = from date from after image MIINUS 1 day
endif
Then the data going out of the start routine is this
customer A, Sales Person X, To Date = 18.03.2010 , from date = 12.03.2010 record mode before image
customer A, Sales Person Y, To Date = 31.12.9999 , from date = 19.03.2010 record mode after image
And the records stored will be this
After initial load
customer A, Sales Person X, To Date = 31.12.9999 , from date = 12.03.2010
After next weeks load
customer A, Sales Person X, To Date = 18.03.2010 , from date = 12.03.2010
customer A, Sales Person Y, To Date = 31.12.9999 , from date = 19.03.2010
Or something like that - but you get the idea.. and yes I have done it before

How InfoSpoke reads time dependent master data ?

Hello Experts !!
How InfoSpoke reads the time dependent master data ?
What key date it reffers to ?
Can you please explain, I want to use this concept in writing master data lookup for time dependent attributes of 0MATERIAL.
Thank a lot !

You can either specify the time period in the filtering area of infospoke or you can implement a transformation BAdI -OPENHUB_TRANSFORM to manipulate the data whichever way that suites your requirement. All time dependent infobjects have datefrom and dateto fields which you can use to choose your data range accordingly.
Hope this helped you.

Problem with Time dependent master data

Dear All,
I have 0PERSON master data infoobject. It is getting records extracted from backend R3 and from a different datasource called 'Peoplesoft'. It has a field 'Date of Birth'. Point of concern here is - whether a particular employee is present in Peoplesoft or in R3, his date of birth is constant. Unfortunately someone hs made 'Date of Birth' as a time dependent attribute of the InfoObject 0PERSON.
We extract data from Peoplesoft from 01.01.1900 to 31.07.2005. From 01.08.2005 onwards, data is getting extracted from R3.There are some employees which are present in Peoplesoft but they are not in R3.
Problem is occuring when the user is reporting on a relevant Infocube containing this 0PERSON infoobject. He does not see the value for this 'Date of Birth' field for certain employees. The reason for this is that the 'Date of Birth' field is blank in the interval 01.08.2005 - 31.12.9999 as this employee was absent in R3 and hence no record/s got extracted.
To view this value in the report - Please suggest me a possible remedy. I thought to write a routine but I dont think it is advisable to change a time dependent master data.
Thanks,
Srinivas

Hi,
There are two ways of solving your issue.
- Remove the time dependent check box for 0person, delete the transactional data, load the master data again and reload the transactional data.
- Write a program to extend the 'Date to' value to 31.12.9999 for all employees.
