How does Master Data delta works.

Can any body please explain me what is data flow in master data delta.Are the ale change pointers utilised , if yes how..And is delta queue used in master data delta.

Amit,
As you may be aware of this, ALE Change pointers are used to minimize the no of records to be sent to the extracting systemextractos. in other words the master data delta is been handled this way. It is better that you read the following that should be giving you some idea.

How the master data delta works

hi, experts
i want to know how the master data delta (ale pointer) works? what the principle is? for example, the 0asset_attr datasource has 20 fields, any of the 20 fields changes can triger the delta? if i enhance 3 fields to the asset master data, does the 3 fields change can trigger delta?

Application Link Enabling (ALE) change pointers are configured and used to be able to trigger processing of an outbound process, such as data extraction, and determine only those Master Data records that have changed. This is all done without the need for a program being required to determine deltas.
SAP delivered program, RBDMIDOC runs periodically and deterlines if change pointers have been updated for specific message types. New or modified Master Data records are automatically initiated via ALE. RBDMIDOC references the correct IDoc program for any given type via TBDME (the TBDME table also cross-references message types with the ALE change pointer table) so that the data goes where it should and is processed accordingly. Tcode BD60 is the interface in SAP for maintaining the TBDME table.
When a change is made to the standard content Master Data record, the delta will be identified. Any columns that have been enhanced to the Master Data will not be identified as a delta because enhancements are a post-extraction process and only get updated after the standard content structure has been populated.

How does the Generic Delta Works

Hi All,
Please let me know how the different types of Generic Delta works i.e. Numeric Pointer, 0Calday and Timestamp with one simple example for each.
Thanks & Regards,
Sunny

Hi........
There are three options for the type of the field determining the delta in a DataSource:
1. Time stamp - The field is a DEC15 field which always contains the time stamp of the last change to a record in the local time format.
2. Calendar day - The field is a DATS8 field which always contains the day of the last change.
3. Numerical pointer - The field contains another numerical pointer that appears with each new record.
Safety Interval Upper Limit of Delta Selection
This field is used by DataSources that determine their delta generically using a repetitively-increasing field in the extract structure.
The field contains the discrepancy between the current maximum when the delta or delta init extraction took place and the data that has actually been read.
Leaving the value blank increases the risk that the system could not extract records arising during extraction.
Example: A time stamp is used to determine the delta. The time stamp that was last read is 12:00:00. The next delta extraction begins at 12:30:00. In this case, the selection interval is 12:00:00 to 12:30:00. At the end of extraction, the pointer is set to 12:30:00.
A record - for example, a document- is created at 12:25 but not saved until 12:35. It is not contained in the extracted data but, because of its time stamp, is not extracted the next time either.
For this reason, the safety margin between read and transferred data must always be larger than the maximum length of time that it takes to create a record for this DataSource (with a time stamp delta), or it must display an interval that is sufficiently large (for determining delta using a serial number).
Safety Interval Lower Limit
This field contains the value taken from the highest value of the previous delta extraction to determine the lowest value of the time stamp for the next delta extraction.
For example: A time stamp is used to determine a delta. The extracted data is master data: The system only transfers after-images that overwrite the status in the BW. Therefore, a record can be extracted into the BW for such data without any problems.
Taking this into account, the current time stamp can always be used as the upper limit when extracting: The lower limit of the next extraction is not seamlessly joined to the upper limit of the last extraction. Instead, its value is the same as this upper limit minus a safety margin. This safety margin needs to be big enough to contain all values in the extraction which already had a time stamp when the last extraction was carried out but which were not read. Not surprisingly, records can be transferred twice. However, for the reasons above, this is unavoidable.
Extracted Data Delta Type
The system uses the delta type to determine how extracted data is to be interpreted in BW, and into which data targets it can be posted.
A distinction is made between the following:
1. Additive delta
The key figures for extracted data are added up in BW. DataSources with this delta type can supply data to ODS objects and InfoCubes.
2. New status for changed records
Each record to be loaded delivers the new status for the key figures and characteristics. DataSources with this delta type can write to ODS objects or master data tables.

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...

Generic and Master data delta.

HI,
Will you please give me the solution for 'The differenet delats we have in generic delta,what actually is a numeric pointer.. how does it pick delat..is it something like it picks a record which has changes in it or it it each neew record..
if suppose we have 1 to 10 customers, will numeric pointer pick every new customer like (11, 12 , 13) as deltas or changes in 1 to 10 customers itself..
And Regarding master data deltas,how will the master data pick the deltas, is it every new record as customer mentioned above will be picked or something other..
the basic thing i want to know is, will it pick any changes in attributes as delta also.. if suppose we have a customer 001 with an attribute as 0ACCNT_GRP, if in any case if this 0ACCNT_GRP has change.. will it even pick this as an delata or not...
i would appreciate your response..
Thanks & Regards,
Shashikanth.

Hi Shashi,
Well....I could give some points on the master data delta..Its achieved by the ALE change pointers mechanism.
There are some tables responsible for storing the changes...CDHDR and CDPOS are good candidates for this.
Hope this helps..

Marc.

How does this IMPORT statement works

can any one tell me how does this statement will work..
I am wokring on Solution manager system , where in there is a function module SSF_FIELD_LIST
to which system passes form name.
import fields to fieldlist
from database stxfcontr(sf) id l_fullname.
stxfcontr is a table which contains value of in a diff
Regards,
mayank

It will import data object stored in memory under named fields to your custom data object fieldlist .
The table which it is stored is name stxfcontr under RELID (memory area) SF .
Cluster key (key of the entry) in that table is behind var l_fullname
Anyhow I think [this link|http://help.sap.com/saphelp_nw04/helpdata/en/fc/eb3bf8358411d1829f0000e829fbfe/frameset.htm] is more that any explanation. Once you study it, you will understand the above.

How does the verizon wifi work? Do you pay monthly?

I want to buy the new iPad with retina display as a gift, but how does this verizon wifi work? Do you pay monthly or have to call Verizon?

You're post is a little confusing. WiFi signals are not done through Verizon unless you are talking about using a Verizon MiFi hotspot such as this http://www.verizonwireless.com/b2c/store/controller?&item=phoneFirst&action=view PhoneOverviewByDevice&deviceCategoryId=13&cmp=KNC-58700000028195084&zipRdr=y.
4G wireless cell signals are done through Verizon. WiFi comes from places such as your home wireless network, or WiFi hotspots at places like Starbucks, restaurants, pubs, etc.
If you are asking about Verizon's wireless cell service, it's $20 a month for 1 gig of data, $30 a month for 2 gigs of data, or $50 a month for 5 gigs of data.

How does committed date in STO- different company codes gets calculated

Dear All,
Please let us know How does committed date (ATP date) in the STO across different company codes gets calculated
Regards
Ahmad Idais

Hello,
RA is always a Company Code specific process due to the possibility of financial postings. I think that your WBS structure better be reconsidered not to mix up different Company codes at different levels, but maybe having a parallel nodes for different Company codes.
I also believe there is a consulting OSS note to explain the standard system behavior, just search the OSS.
Since you already have a master data in place it must be quite easy for you to test how the system behaves.

Work Schedule in HR Master Data Feeding Work Center!

Hi,
I have several questions on how work schedule in HR master data relates to the work center for capacity planning.
1. How do we assign the employee to a work center? is that in the HR master data or work center or some other transaction?
2. If we can assign an employee to a work center, how the work schedule in the HR master data feeds the work center capacity? Is there any button that I can control whether I want to feed the work center capactiy from HR master data work schedule or from manual input directly to work center?
3. If I can feed the HR master data work schedule to work center, what do I need to do to reflect the vacation time or sick time which is not in the work schedule in the HR master data to the work center?
Thanks,
Ting

Hi,
For starters, please take a look at the following discussion:

Master data delta

BW Experts,
Right now we are doing all full loads for our master data. I have heard about Master data deltas which brings only the changed and new records. what is the setting to be made in BW for this. Also what is the setting to be made in R/3 3.1i and R/3 4.7. Help is greatly appreciated.
Thanks
Ashwin

Hi,
For MD deltas to occur, the process is the same as transactions delta. On the R3 side you need to make sure that the std datasource is delta enabled (most are). If its a generic one, then you need to make that delta enabled if not already.
On the BW side, you need to set up an infopackage to do initialization without data transfer(since you are already doing full loads) and then set up the delta.
One word of caution here, would be to do a full just around the time you set up the delta, so as not to lose any delta data, as there might be new MD records or changes to existing ones that might not get captured. This is very rare, but its better to do a full around that time.
Cheers,
Kedar

How does the follwoing query work?

Want to know how does the follwoign query work??
For every row in flsp
the subquery is going to get executed or is it just one time execution of the subquery??
UPDATE flsp
SET (DURATION, sdr, inr) =
(SELECT SUM (tot_charges), SUM (tot_charges_sdr),
SUM (tot_duration)
FROM t
WHERE t.sender_pmn = flsp.sender_pmn
AND t.recipient_pmn = flsp.recipient_pmn
AND t.imsi_min = flsp.imsi
AND TRUNC (t.call_date) = TRUNC (flsp.call_date)
AND t.call_type = flsp.call_type
AND t.service_code = flsp.service_code
GROUP BY sender_pmn,
recipient_pmn,
imsi_min,
TRUNC (t.call_date),
call_type);

Why are you moving all this data around and utilizing temporary tables instead of directly querying the underlying data on an 'as needed' basis?
I think you have undertaken entirely the wrong technical approach to whatever business problem you are attempting to solve (though it's hard to say for sure as we still know little of what you've got going on).
So back to step number one like i asked before.
Can you explain (from the very beginning) WHY you are attempting this type of set up?

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.

Is it possible to have your whole family on one apple id or is it better to have each person have there own? If each has their own does each id have to buy their own music and apps? How does find my iphone work with one apple id or two?

Is it possible to have your whole family on one apple id or is it better to have each person have there own? If each has their own does each id have to buy their own music and apps? How does find my iphone work with one apple id or two? also I am going to be going off to college soon should I make an itunes id for my self and how will I get all the music from the old id?

Is it possible to have your whole family on one apple id or is it better to have each person have there own?
Yes, it is possible. 1 apple ID can be associated with up to 10 devices.
If each has their own does each id have to buy their own music and apps?
Yes, all purchases are non-transferable.
How does find my iphone work with one apple id or two?
Every device associated with one apple ID through Find my iPhone is tied to that Apple ID; Find my iPhone will work in the same way with up to ten devices associated with one apple ID. You cannot enable Find my iPhone for one device across two apple IDs
I am going to be going off to college soon should I make an itunes id for my self and how will I get all the music from the old id?
If you have authorized a computer with the old apple ID, you can transfer old media purchased through the old to other devices via iTunes. This doesn't mean the media purchases through the old apple ID it transferred to the new account. If you plan to make future purchases and don't wish to share them with others, make your own apple ID.
