Master data time dependency

Hi if i put the manager as employee in cube then we are loading the data from flat file full load then it will overwrite the manager name in cube for last month
say i have manager name john for month 08
i load the trans data from flat file it will take it
now next manager name john now if i load the data it will overwrite, user want to maintain the history so that if i run the query for month 08 it should show me manager name john and if i run the query for month 09 it should show me manager name john. please help how to resolve this
since making too many time dependent master data will over load the system so user do not want that. also is there any way to load delta from flat file in bw version 3.0
i will reward 100% point if anybody can clarify the approach to make this happen

Hi,
If you set the master data attribute as "time dependent" it will track such changes as well as validity dates.
Of course, you would not make even the majority of master data time-dependent, but in cases where modeling calls for it (such as this), it probably should be utilized. It will not "overload the system".
Please be clear - while master data InfoObjects contain over-write functionality, an InfoCube does not. Data loaded into a cube simply is an "insert".
For your generation of delta, note that the ODS object contains a change log mechanism. This change log can generate a "delta" from a flat file load or any kind of load. This delta can then be used in other data loads sourced from the change log.
Also, you might consider a technique to load a complete history of master data into an ODS object. You can model an ODS without any key figures, but be aware the defauly will be "update", where the only complete history is in the change log. You could implement a "technical key" in update rules, so that each record gets a unique identifier, preventing over-write. Alternatively, if you are on BI in SAP NetWeaver 2004s, you can use a write-optimized DataStore object, which automatically assigns a unique technical key to each record (so that you have complete history), but has no change log.
Thanks for any points you choose to assign -

Master data time dependent

hi bwers,
Can any expert tell me, Under what reporting senarios do we need to matintain master data time-dependent

Hi,
You do this when you want to maintain the history. Like for 0COSTCENTER master data, most of it is time dependant. As an example, the person responsible for a costcenter...you want to know who it is and also who it was earlier. This can only be done with time dependant master data as it adds the from and to fields to the data.
Hope this helps...

Query Designer Master data Time Dependent

Hello
im with this problem
i have master data:
material/till/since/price/description
1/14.01.2010/01.01.1000/20/Material1-old
1/31.12.2010/13.01.2010/15/Material-new
cube:
material/date/quantity
1/01.01.2010/5
1/15.01.2010/20
in my querty designer, i put the 0calday with selection options
when i insert for example 01.01.2010
its couting the "material-new" ( 15*5) it shoudlnt
it should calculate the old one. (20*5)
how can i fix it?
regards,

Hi Amit,
At "Query properties" screen, you can define a "Key date". It can be fixed or it can be calculated from a user-input variable. If you do not specify one, the default key date value is the date on which the query is executed (today).
For time-dependent data, the key date determines the time for which the data is selected (material price, in your case). However, there is only one key date per query. You can't make it dynamic depending on the value of 0CALDAY in every transactional data record.
Perhaps you might consider the option of adding 0AMOUNT to your InfoCube, and precalculate the formula quantity*price using an ABAP routine which reads price from InfoObject Q table, filtering by OBJVERS='A' and DATETO/DATEFROM=0CALDAY.
I hope this helps you.

Master data - time dependent - reduce volume..

Hello,
I have following BW 3.5 scenario: InfoObject which is marked as data target. In the object definition I have different attributes. One of this attribute is indicated as time dependent.
The InfoObject is filled via two update rules. In this two update rules the valid "from date" is filled with each load (monthly) from system date. The "to date" is fix value.
I have following example:
Date to              Date from           Used (U) / New (N)
25.05.2008     01.01.1000
10.06.2008     26.05.2008          N
15.07.2008     11.06.2008                  N
07.04.2009     16.07.2008          N
15.04.2009     08.04.2009          N
31.12.9999     16.04.2009          N
So with each full load I have an additional record.
Is there a standard function / module that loops over my time dependent table (q-table) and only if there is a change (e.g. from N to U) an additional record is created.
Any idea how to create a routine. How should coding look like?
Any input is welcome.
Thanks in advance.

Master data time dependant attribute in query for several dates

Hello all,
I need to create a query to display prices for a material in different periods.
The user will enter a period interval. For each period, they want to know the material price the last day of that period.
Material price is a time-dependat attribute of material, and I created one formula variable to display it. The problem is the using the key-date of the query only works for a date, but not for severals.
Is there any other way to do it?
If not, the only solution I find is to have in the infoprovider the prices that I need, but I don't think this is a good practice.
Any suggestions?
Thanks!

I have just seen something: in fact the created lines are:
Key1 Compound1 fromdate todate attr1 attr2
0001 L 01.01.1000 01.01.2006 <empty
so as you can see, the right interval is created but the attributes are not up to date.
Cheers.
Cyril.

Time dependent material master data

Hello,
Would you please explain me how to make Material master data time dependent?
Points will be rewarded!!

Hello Siggi,
Thanks for your respond.
I am using BW3.5 and for 0materia there are lots of attributes and for every attributes there is a "time dependent" click. Do I have to click all of them? Can you explain the theory behind that?
Mater data will be maintained respectively if I can change it to time- dependent.
Thank you very much,

Change to cost center in time dependent data. Can I rerun depreciation YTD?

I need to change the cost center in October (Period 10) Period 9 and prior are already closed. I thought that since I put the Interval for the new cost center as 1/1/11 that it might do and adjustment in October reversing the depreciation posted for the old cost center and put the YTD depreciation in the new cost center, but it did not. it only posted the current month depreciation to the new cost center. Is there any way to do this? Thank you very much.

Hi. Thanks for your reply. I went into the ABAA screen, but I am afraid to process this transaction because I do not understand what is going to happen. I cannot find any documentation that explains this. I have already changed the cost center on the asset and run depreciation. It posted the current month depreciation to the new cost center, but it did not make a correction to the prior periods. I am not creating a new asset, i just want to reclass the prior months depreciation (in the current year) to the new cost center. In case it will help I provide some details:
Asset acquired 5/1/11 Depreciation posted to Cost Center A From May - Sept $1,796.06 per month x 5 = $8,980.30
Before posting Oct depreciation, I went to Master Data - Time Dependent - and changed the cost center as of 1/1/11. So I now have two intervals: From 1/1/1900-Cost Center A, and From 1/1/11 - Cost Center B. I then ran the regular depreciation for Oct. It posted Oct Depreciation of $1,796.06 to the new Cost Center-Cost Center B. My total YTD depreciation is now $10,776.36, but it is split between two cost centers. I need to move the depreciation from Cost Center A to Cost Center B for the prior months. If it was a Journal Entry, I would do it as follows in the month of October, so my YTD numbers would be correct.
Debit Depreciation Cost Center B $8,980.30
Credit Depreciation Cost Center A $8,980.30
Then when I run my October numbers it would show zero depreciation in Cost Center A Year To Date (and negative 8,980.30 in month of October)
If i follow the steps you propose, what would be the result? Thanks so much!

Compare time depednt master data for two key dates in a report?

Hello all,
We have a requirement where we want to see the difference in master data at particular key dates (time dependent master data).
Like if employee has State = OH till yesterday (12/01/2008) and today it is changed to State =KY (12/02/2008 to 12/31/999) loaded in BW which is time dependent.
So basically if you run the query for Key date 12/01or before you will see OH as state and if you run query for key date 12/02 or further you will see KY.
We want to create a report where we want to list employees and compare in two columns basically the previous value and the current value. So input would be two key date variables and the report would look like
Employee Key date 1(state) Key date 2 (state)
Employee1 OH KY
Has anyone done this before, can someone help me doing this?
Thanks,

Hi ,
For this scenario , Can you please create variabale ( From value -- to value ) in the key figure date .And by using the time period in the varaible u can get the employees for both the states ...
Hope this helps out
thanks

Hi,
Go to the function module RSD_IOBJ_GET to find the object name of the dimension. Go to SE37 & proceed as follows.
I_IOBJNM = 'Info Object Name'
I_OBJVERS = 'A'
I_BYPASS_BUFFER = 'X'
and then Execute the FM.
Double click on the "'E_S_VIOBJ'" and find the number in the field 'u201ENUMBRANR‟'
and add BIM to the number taken from NUMBRANR.
Goto SNRO T-Code and enter BIM+the number and edit.
From Edit--> Set up Buffering --> Main memory, select the buffering check box and enter approx 500.
This needs to be done for all the master and your dataload performance would improve.

How track changes in production order which is already Read PP master data

Hi Gurus,
Due to some unavoidable reason my client has to do Read PP master data time and again, now my client having a requirement that want to see what has been changes in Production Order.
We already created 1 report for that which tracks whatever has been changed in Production Order but having a constraint in it. That It could not be able to distinguish to which order READ PP MASTER DATA done.
So my query is how to map that in report. As sytem Status directly changed to CRTD phase.
Any table which can track the changes once the order been through with READ PP MASTER DATA?
As there are huge number of Production Order so we can go and open each order to see the Status changes in each and every order.
Hope to get a reply soon.
Regards,
Sap User

Hi,
A suggestion:
Change the specification as, log changes at each save instead of Read PP Master Data, as the changes would become effective only upon save. So if this is acceptable then 2 options, 1. Go with OCM feature or 2. Refer note - 390635
Revert if you face any issues.

Loading InfoObject master data into Cube

Hi Guys,
I have a question. I created an InfoObject as a data target and loaded data into that data target. I created a cube and I want to include this infoobject in the cube. Now How do I load data into this cube from the InfoObject.Because the InfoObject doesnt have any option to select data targets, since it is master data.
Data is being loaded into the InfoObejct. But when I check the cube there is no data.
How do I load this master data into the cube without update rules?
Thanks in advance.

Hi,
i think u need load some value to transaction data so that you can report on it, but how you are going to decide which row will be having which value from master data? in general value for this should come from transactional data, or you could assign some constant value to it.
Do you want to use any attribute of Inoobject in report? And if you have any key value for that coming from Transaction data, you can use rule type as read from master data
It depends upon your requirememt.
Since you want to restrict the values of the cube which are going into the report then you should include this object into the cube.
In any case if you want to restrict the value of the transactional data in the cube with either the value of the objects ot the attributes of object you will have to add this object into the cube.
As you said you can load master data and use in report but how you are going to use it..............you will have to include it in the cube to use it.
Also you can check whether this object is attribute of some other object already in the cube in that case you can make it navigation attribute and then use it for the restrictions in the cube.
In this case only you do need to add it to the cube,But if it not an attribute of any object then you must add it to the cube.
You have to get the value of your infoobject into Cube from datasource, even though you want to use attributes only.
You will have to add it and it wont have any effect the transaction data getting loaded into the cube will be different from the master data only SID's are matched during loading of the data.
You should load separate master data into the 0recontract infoobject with the master data source and make the respective object contract type and contract category as navigation there.
Also you should add 0recontract to the cube and update it from the transaction data source as you have said that it can be updated.
Then just do the normal restrication at the report level
You can make this display attribute as naviagatioonal first in the master data object and then in the cube make this attribute as navigational.
then you can use it to restrict in the cube
You can use Category as InfoObject in your cube, and while loading data for your infoobject in the rule type you can use option as reading from master data. It will take key of infoobject, and will update attribute value in your cube.
http://help.sap.com/saphelp_nw04s/helpdata/en/e5/f913426908ca7ee10000000a1550b0/content.htm
You can also restrict with attributes value, Just in the restrcition of your infoobject in query designer, slelect left-botton button of 'Dipaly Other Values', here you can select you attribute and its value for restriction as well

Hareesh

Error during master data delta load

Hi All,
I am loading delta master data to an info object 0DPM_DCAS through a flexible update.
Received an error "101 data records in table /BI0/XDPM_DCAS marked for deletion...
158 duplicate record found. 126 recordings used in table /BI0/XDPM_DCAS" at the Update level.
The status is red. There is no additional info in the Error Message button.
Also subsequent deltas cant be triggered and it says "Repeat cant be requested".
Please suggest an explanation and an way out.

Hello VishNo,
How r u ?
This error is because of the Duplicate records existing in the InfoObject. Also, seems to be the problem in the Master Data Time independent navigational attributes table. Check the data and also the Monitor screen Details Tab entries & come back again.
Best Regards....
