Delta loading basic question

Hi guys,
since I'm learning and testing the SAP Netweaver BI 7.0 I'm loading with full upload to the targets (DSO, InfoCube).
Now I have read about loading with delta load.
As I have undetstood the delta load enables me to load only new data to the targets.
Now I'm wondering that in some forum threads people are writing that more Infopackages are neccessary if you want to load with delta.
Is it correct that more Infopackages are neccessary for delta load and why?
Is a How-to within SDN available? I couldn't find anything.
Thanks!

Hi,
To do the Delta one must load the INIT.
You can do inti in two ways
1. INIT with Datatransfer
2. INIT Without Datatransfer
The following are the general steps to load Delta
1. One IP for Init without datatransfer
2. One IP for Full Load
3. Another IP for Delta Load
You can also do
1. Create an Infopackage to do the INIT with Datatransfer(This is equivalent to INIT without Datatransfer+FULL load)
2. create another infopackage & make it delta in the update mode
Hope it is clear & helpful

Class Loading.Basic Question

Hi,
I wrote a small piece of code and it is running fine.
     Enumeration enP = lP.getNameList();
     int i=0;
     while (enP.hasMoreElements()) {
          Object nE = enP.nextElement();
          String nV = nE.toString();
          System.out.println(nV);
I am in doubt,because as far as I know Enumeration is an interface as sucj an interface it is not supposed to have code. So, my question is which class is in fact been used by the program?

All you can know it that whatever class it is, it
implements the Enumeration interface. Well that's not really true. If you're really dying to
now what type it truly is, just print out its
class:Enumeration enP = lP.getNameList();
System.out.println( enP.getClass() );
That code shows what the class is on a specific version of a specific vendor's library. If you try to rely on that information, don't be surprised if it's a different class in another vendor's library or even the next version of the same vendor's library.
The truth is you really don't know what class of object a reference will point to when you write the code, at least if the reference type is non-final.

Basic Question on Copy and Delta link which one to use when?

Hi
Its basic question
My understanding about copy and Delta link is
Copy doesnot ahve direct relationship with source object (but it acts as a sibling) any changes done to spurce object does not affect target object.
Where as Delta link will have a parent child relation ship between source object bacially its a copy of source and inherits id properties. in case if i change source object does this affect target object, we can delete, add content to delta link target object.
let's say if i want to use standard quickpoll iView do i need to use copy or delta link similarly for other iviews, worksets, roles which one will be better.
Regards,
Murali

Murali,
Yes, your understanding is right.
Case 1 : Copy
A- Object
B- Copy of A
Both of them are independent.Any changes in A are not dependent on B and vice versa.
Case 2 : Delta Link
A - Object
B - Copy of A (via Delta link)
Any changes to A are reflected in B, as A is a parent and B a child.
But B would be an independent entity.Any changes to B would not effect A.
When you use either of them, depends on your need. When you are working with standard iviews or roles or workset, you can do a copy of the original, because in most cases we would not make changes to the standard roles or worksets or iviews. There by eliminating the process of making a delta copy.
But, if you are dealing with the roles that you have created and want to make a copy of it, you can use a delta link, because, even if you want to add more iviews and worksets to that role, they would get reflected when you make a delta copy.
Hope that helps.

Question for delta loading

Hi, Gurus,
I load data from a flat file into one infocube with delta loading option, and in the related datasource, i chose 'additive delta' option.
However after delta initial and delta update, when I checked cube content, I found that there are 2 records with the same characteristic value (just like duplicated key), and my expectation is to sum key figure with the same characteristic. Who can help me on that?
BTW: when I check delta queue, why there is not any queue?

Ls,
Please do not post same question in both forums - please refer the answers in the other post in the other forum.

Delta load question

Hello All,
Could you please help by providing a high level step by step solution for the following:
Currently we have an ODS that is being filled by a selective delta load(2LIS_04_S621) by using production order ranges. We have loaded this data for the last 5 years and the number ranges are plant specific.
We now have the need to load all production orders for all plants which span over several number ranges. Please advise.
Thanks

Hello,
What about in R/3, did the extractor has data for all the plants , if yes then you can perform the repair full request excluding the selection previously given ( for the selective filed you can write a routine to exclude the current seletcion ).Might be this can help.
Thanks,

Question for delta loading, why can not update existing record in cube

Hi, Gurus,
I load data from a flat file into one infocube with delta loading option, and in the related datasource, i chose 'additive delta' option.
However after delta initial and delta update, when I checked cube content, I found that there are 2 records with the same characteristic value (just like duplicated key), and my expectation is to sum key figure with the same characteristic. Who can help me on that?
BTW: when I check delta queue, why there is not any queue?

Hi,
In uploading of flat file , If you are able to capture the changes to the previously loaded records, Then you can follow the additve delta. So it decreases the time of uploading .Only changed or new records will be uploaded every time.
If you are not able capture the changes in flat file ,Every time you have to do full upload ,Before this delete the contents of Infocube. (Assuming there is no ODS B/W Infocube and Flat file).

Basic question

Hello, i have a basic question. if i have defined 2 fields in a cube or a dso:
Name Quantity
and from the external flat file i get some characters for my quantity field. would my load fail? for standard dso and for write optimized?
NOTE: quantity field is a keyfigure defined as numeric.
and the load coming in has "VIKPATEL" for Quantity field and not numbers.
thanks

Hi Vik,
Yes, the load will fail.
May be you coud first load this data into BW (into PSA) and set both fields as characters fields. Then you can create DSO, do transformation from this PSA to the DSO, and put your logic as to what do you want to do with those Quantity that is not number (e.g. convert to 0, or 'Not assgined', etc).
You can use transfer rule, or a clean up ABAP code in the start routine.
Hope this helps.

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.......

Delta loading and Process chain BI

Hi experts,
Two Issues.
1)As i am loading FI data into dso through a process chain which includes Start process>Delta infopackage(which gets data upto psa)>Delta dtp-->Datastore activation.
But infopackage is picking up deltas but DTP is picking up all the previous records plus deltas.
100 records -- 1st day throught Intialization of Delta with Data Transfer
2 delta records -- 2nd day
But DTP is picking up 102 Records on the 2nd Day, which means it is also picking the old records as well.
The DSO must have just 102 records but it is having 202 records.
2) A process chain in running daily as scheduled , but I rescheduled with new scheduling options without deactivating the Process chain.
My Question is
Will the Process chain run for the OLD and the New Schedule or
Is it going to run for new schedule or old one?
or
will I face any Problem because I did not deactivate and made changes to the Change.
Please help me in this matter.
Thanks in advance.
Bhadri.

First query:
I believe that u have used FUll update type DTP is instead of the Delta DTP.. Please cross check the Update mode of the DTP once.
To resolve this issue, delete the total content of the DSO as u have Init and delta loads in PSA. And then using the Delta DTP of the Process chain, load the data. It will extract the total cotent what ever is there in PSA, and later the same DTP will act as the Delta type and will pick the data from the New request of the PSA.
Second Query:
Its always suggested to deschedule the process chain before changing the schedule timings. When ever u do this type of scheduling, just check how many number of JObs available in Schedule mode, if u can see more than one, then delete the older one and keep the new one as it is.
But I always suggest you to deschedule the process chain and reschedule PC with the new timings and then activate the same.
Thanks

Can we use both 0FI_AP_3 and 0FI_AP_4 for Delta Loads at the same time.....

Hi Gurus:
Currently my company uses 0FI_AP_3 for some A/P reporting. It has been heavily customized & uses Delta loading. However, SAP recommends the use of "0FI_AP_4" for A/P data fro delta loads. I was able to Activate 0FI_AP_4 as well & do some Full Loads in Dev/Test boxes. Question is whether I can use both the extractors for "Delta" loads at the same time......? If there are any issue, what is the issue and how ccan I resolve it? Is the use of only one extractor recommended......??
Please let me know as this impacts a lot of my development....! Thanks....
Best...... ShruMaa
PS: I had posted this in "BI Extractors" forum but there has been no response...... Hope to get some response.......! Thanks

Hi,
I would recommend you to use 0FI_AP_4 rather using both, particularly for many reasons -
1. DS: 0FI_AP_4 replaces DataSource 0FI_AP_3 and still uses the same extraction structure. For more details refer to the OSS note 410797.
2. You can run the 0FI_AP_4 independent of any other FI datasources like 0FI_AR_4 and 0FI_GL_4 or even 0FI_GL_14. For more details refer to the OSS note: 551044.
3. Map the 0FI_AP_4 to DSO: 0FIAP_O03 (or create a Z one as per your requirement).
4. Load the same to a InfoCube (0FIAP_C03).
Hope this helps.
Thanks.

Basic questions about Infocube

Hi, everyone.
I got very basic questions about infocube data handling.
With infopackage, I extracted all the data about employees from R/3.
But there were some mistakes during inputting employee data, like positions,
so I just extracted those employees data once more.
Now I have two requests in infocube, where the first one has some wrong data.
Is there any solutions about this?
I might got it all wrong, so as beginner, any suggestions and explanations will
be grateful.

Hi,
You can manually delete the earlier request by going in the Manage option of the cube. select the request and click on delete icon at the bottom.
Other option is to make setting in the Infopackage to delete similar or overlapping request.
Data target tab --> 6th column Automatic loading / deletion of similar request. --> click on the blank icon --> you will get a pop-up --> select the radio button - "delete existing request" --> Select Conditions --> Infosource are same, datasource are same and source system are same, --> selections are "Same or More Comprehensive "

Basic questions about the CM handling of Photoshop

I have some basic questions how Potoshop handles colour management. Most probably this has been discussed many times before, but frankly, the manual is pretty poorly written on this subject. I do understand the principle of colour management pretty well, but am not sure whether I understand what Photoshop is doing. So could somebody please comment whether my reasoning is correct or not.
Let's assume my monitor is calibrated and its profile loaded in OSX's monitor preference panel. Let's further assume I'm working strictly in RGB.
Is the following correct:
• When I open a picture which has an embedded profile, then Photoshop first calculates the "true" values from the embedded profile (whatever this means) and from this point the screen representation based on the profile which I defined in the system pref pane. So the screen representation remains always the same, regardless of the embedded profile (besides some possible conversion artefacts, especially on the edges of the colour space).
• The same holds true in the opposite direction, so when I work on that picture on screen, then no matter which RGB space I pick as my working space, the result will always be exactly the same (except those aforementioned artefacts).
• Hence it doesn't matter which RGB colour space I choose as my working space, it could be sRGB, Adobe RGB, "my own wild profile", whatever, the results are always the same. Of course the RGB values will differ, but this will be compensated by the embedded profile.
• Yet the theoretically best working space is the colour space of my monitor, because this minimizes possible artefacts.
• When I "convert" the picture from one profile into an other, then not only that new profile is assigned and embedded, but also the RGB values are recalculated accordingly, so that the result will remain the same. For example, I could first "convert" a picture from the camera space to my monitor space, then work on it, and finally "convert" it to sRGB before uploading it to a web site.
• When I "assign" a new profile, then a new profile is simply assigned and embedded but the RGB values are not adjusted. So the RGB values remain the same, but because a different profile is embedded, the picture will actually be changed. Since Photoshop will recalculate the screen representation based on that new profile (and the monitor profile), I will see this change on the screen. (This action doesn't make much sense, except maybe to simulate the possible outcome on a system which misinterprets the profile, e.g. assumes sRGB.)
• And finally, when I leave the picture untouched but change the monitor profile in the system pref pane, then of course the picture will not change, but its screen representation will change, because Photoshop uses that profile to calculate the screen representation. (This action makes even less sense, of course.)
Have I understood? Then I have two final questions:
• When I open a RGB file without any profile in it, what does Photoshop assume? How does it calculate the screen display? What does it do if I "convert" such a picture or "assign" a profile?
• If I select in the colour settings as working color space the monitor space, then the colour managment rule for RGB changes to "Colour management off" and can't be changed to a different value. I don't understand this.
Thanks for your patience.

• Yet the theoretically best working space is the colour space of my monitor, because this minimizes possible artefacts.
No.
(Edit: Any one screen usually has to be considered incidental, changing and transient and is not the target-medium, so it makes little sense to work based on its specific limitations.)
• When I open a RGB file without any profile in it, what does Photoshop assume? How does it calculate the screen display? What does it do if I "convert" such a picture or "assign" a profile?
If one opens an unprofiled file, Photoshop treats it as if it had the profile selected under RGB-Working-Space embedded and calculates display and conversion on that basis.
(Edit: And that’s the danger of unprofiled files – they would look different if someone edited them who used a different Working Space.)
Assigning such a file a profile is no different from assigning a profiled image a different profile – the RGB-values remain unchanged, the »key« for interpreting them changes and subsequently it will be displayed differently.

Loading through Process Chains 2 Delta Loads and 1 Full Load (ODS to Cube).

Dear All,
I am loading through Process chains with 2 Delta Loads and 1 Full load from ODS to Cube in 3.5. Am in the development process.
My loading process is:
Start - 2 Delta Loads - 1 Full Load - ODS Activation - Delete Index - Further Update - Delete overlapping requests from infocube - Creating Index.
My question is:
When am loading for the first am getting some data and for the next load i should get as Zero as there is no data for the next load but am getting same no of records for the next load. May be it is taking data from full upload, i guess. Please, guide me.
Krishna.

Hi,
The reason you are getting the same no. of records is as you said (Full load), after running the delta you got all the changed records but after those two delta's again you have a full load step which will pick whole of the data all over again.
The reason you are getting same no. of records is:
1> You are running the chain for the first time.
2> You ran this delta ip's for the first time, as such while initializing these deltas you might have choosen "Initialization without data transfer", as such now when you ran these deltas for the first time they picked whole of the data.Running a full load after that will also pick the same no. of records too.
If the two delats you are talking are one after another then is say u got the data because of some changes, since you are loading for a single ods to a cube both your delta and full will pick same "For the first time " during data marting, for they have the same data source(ODS).
Hope fully this will serve your purpose and will be expedite.
Thax & Regards

Some basic questions on File Adapter

Hello all,
I have some basic questions on XI and File Adapter and hope you can help me. Any answer is appreciated.
1. Can I use NFS transport protocol to poll a file from a machine in the network, which is not the XI? Or do I have to use FTP instead?
2. If I understand it correctly - when using the FTP-File Adapter, XI has the role of a ftp client. I have to run a ftp server on my distant machine. XI connects to FTP-Server and polls the file.
Can it also be configured the other way round? The scenario I think of would be: FTP client installed on distant machine, which connects to FTP-Server(XI) and loads up a file. So XI would act as FTP Server.
I know this works, if I install a ftp Server on the computer my XI runs on, and use the NFS-File Adapter to observe the folder. But I want to know, if I need a second, independant ftp server for this.
3. And last but not least: When do I need the active ftp mode instead of passive?
Thanx a lot for your answers!
Ilona

XI cannot act as FTP server, but it is always a client. When XI is reading (File sender adpater) when XIis writing than it is File Receiver adapter

It depends on your firewall configuration. The best and the fastests is active mode but not always available.

Problem with delta load urgent!!

Hi,
I have a problem with delta load
We have an IP, which loads data from R/3 system daily, its a delta load to the ODS and it updates to the cube with the selection on Company Codes and 0FISCPER
we are in 3.5 system
For a couple of company codes A & B, the init was done for the period 07.2010 to 12.2099 and after tht the deltas are loaded from 07.2010 till 12.2099 and there's no pblm with tht
Now, there was some updation in R/3 system and the data was maintained for the company codes in A& B for the FISCPER 001.2010 to 006.2010, for which init wasnt maintained...
now how shall we need to load the init in this case? dnt ask me how the postings was done in R/3, but my pblm is purely related to the loading data in BW from R/3, as its very imp for the customer to see the data from 01.2010 to 12.2010 in reports, but the data was only available in reports from 07.2010 onwards
do i need to create another IP and maintain the init for 01.2010 to 06.2010? so tht this selection will automatically appear in the ODS delta loading infopackage
pls throw ur inputs ASAP
thank you

Hi Prince,
No need to maintain any Init for this data, It will be enough if you can load the data from jan 2010 to jun 2010 into your Info Cube.
Follow the below steps:
1)create full load IP for this data source.
2) give the selection as A and B company codes and 0FISCPER as 001.2010 to 006.2010
3) in menu bar, click on scheduler --> select full repair request
4) In the next screen check the check box and save
5) Now execute the IP, it will the data with out disturbing your daily delta.
follow the same procedure to load data till to your Info Cube.
Please revert if you have any questions
Regards,
Venkatesh
