SLT Replication for the same table from Multiple Source Systems

Hello,
With HANA 1.0 SP03, it is now possible to connect multiple source systems to the same SLT Replication server and from there on to the same schema in SAP HANA - does this mean same table as well? Or will it be different tables?
My doubt:
Consider i am replicating the information from KNA1 from 2 Source Systems - say SourceA and SourceB.
If I have different records in SourceA.KNA1 and SourceB.KNA1, i believe the records will be added during the replication and as a result, the final table has 2 different records.
Now, if the same record appears in the KNA1 tables from both the sources, the final table should hold only 1 record.
Also, if the same Customer's record is posted in both the systems with different values, it should add the records.
How does HANA have a check in this situation?
Please throw some light on this.

Hi Vishal,
i suggest you to take a look to SAP HANA SPS03 Master Guide. There is a comparison table for the three replication technologies available (see page 25).
For Multi-System Support, there are these values:
- Trigger-Based Replication (SLT Replication): Multiple source systems to multiple SAP HANA instances (one source system can be connected to one SAP HANA schema only)
So i think that in your case you should consider BO Data Services (losing real-time analytics capabilities of course).

Modeling the Data model when multiple source systems

Hi gurus,
i have a scenario where i am getting data from multiple source systems all R/3 but from different locatins.
my doubt is if i have to do reporting on the data available.
1. do i have to build seperate infocubes for each source systems or build seperate data designs for each source system .
2. How can i consolidate the different source sytems data into one and report sensibly as well as without loosing the source system identification.
thanks and regards
Neel

Hi all,
thanks for your focus, ya i am also thinking of have a flexible solution where in i can do it easily as well as we don't have much of complexcity, but wanted to try different options as well so that we can go for best one.
I thought of multiprovider at first when RafB suggested, and i agree with you as well Lilly, that data volume will be a problem, so keeping all this in view i want to build a solution where in it will be sensible as well as not confusing in reports ( i mean clear and readable reports)
[email protected]
please kindly forward any documents which might be helpful for me in this scenario
thanks and regards

LookUp to the same table with multiple conditions

Hi,
I nead to do a lookup to the same table in the flow but with diffrent quieres, each query contains it's own 'where'.
Can I do it somehow in one look up or do I have to use a few ?
select a from table where a=1
select b from table where c=3
Thanks

Hi,
Using multiple lookups will be a cleaner approach. If you are using multiple lookups on the same table consider using Cache transform. Refer the below link for details on Cache transform
Lookup and Cache Transforms in SQL Server Integration Services
Alternatively if you want to go ahead with single look up , you may have to modify the SQL statement in the Lookup accordingly to return the proper value. In you case it may be
select a,b from table where a=1 or c=3
Note : Consider the above as a pseudo code. This needs to be tested and applied based on your requirement.

For the same table in the same page, how to use 2 different forms (simple and tabular)?

Hello! How I can be on the same page with the same table insert and update operations using 2 different forms (single form and tabular form)

Thank you Gramps. It took some time, but I've got it working now. I had to re-do all the user authentication actions from scratch for one of the databases, but it's finally behaving itself now. I appreciate you pointing me in the right direction.

Mapping to the same table through multiple references

Hello,
I'm trying to map aggregate fields (from my target) to mutlitple tables (back on my source), but am hung up because I need multiple references to the same table (basically a lookup values table) in my target. I believe that the problem lies in not being able to reference (in the mapping workbench at least) the same table more than once (such as through an alias, or otherwise defining multiple references) in the multi-tables tab. Is there a way around this, or some other approach to mapping it that I can take?
Thank you,
John

Not exactly sure what you are trying to do, perhaps listing the object model and data model would help.
If you are having trouble mapping the aggregate in the Mapping Workbench you may be able to workaround the problem through using a descriptor or project amendment method and defining the mapping through the code API.

How to combine 2 the same tables from 2 different databases

We have made 2 databases company1 and company2
Both databases contains the same tables
Now we want to make a report with server reporting services. The report must give us information from the 2 databases.
We use the following query:
SELECT     '501'as divisie, GRV_DebtorOutstanding2.[Debtor code] AS Debiteur, GRV_DebtorOutstanding2.cmp_name AS Naam, SUM(GRV_DebtorOutstanding2.[Outstanding Amount]) AS Saldo,
                      GRV_DebtorOutstanding2.blokkade, GRV_Debtors.City
FROM         [501].dbo.GRV_DebtorOutstanding2 INNER JOIN
                      [501].dbo.GRV_Debtors ON GRV_DebtorOutstanding2.[Debtor code] = GRV_Debtors.[Debtor code]
WHERE     (GRV_DebtorOutstanding2.blokkade = 'B')
GROUP BY GRV_DebtorOutstanding2.[Debtor code], GRV_DebtorOutstanding2.cmp_name, GRV_DebtorOutstanding2.blokkade, GRV_Debtors.City
ORDER BY Debiteur
when we use the same query to select the data of the other database in the same query it doesn't work. I have tried it with the command Union All
But it crashes,
please help, to fix it

Hi Robert,
According to your description, you have created two same databases. When you run the same query for the second database, it doesn’t work.
In your scenario, since databases are the same and the query for first database can work fine, it should also work when query the second database using the same query. When you create second dataset, please check if you have used a correct datasource
which is second database. Then try to run the query again. If issue persists, please share the error message around the time when you query the second database.
If you have any question, please feel free to ask.

The same Object Version Number for the same person id multiple times

Hello all,
I am currently facing an issue with HRMS tables and the object version number for employees. I am trying to write a report but due to the same object version number for the same person appearing in several row i am getting duplicate information. For example,
person id 91 object version number 32 is on 4 rows and i have no idea why...help please guys, I'm at a lost so far 50 people are facing the same issue.

Hi Baal666bobo,
The person table is date-tracked, so the PK has effective start and end dates as well.
Get the correct record with sysdate(or any particular date) and then check the OVN.
Cheers,
Vignesh

How do I sum across the same table in multiple sheets?

So I'm trying to figure out an annoying problem.
I have a largish (100's) amount of data with each collection being a table in a sheet, one sheet per data collection. This means I have 100's of sheets, each with the same table name and layout. Each sheet has several hundred data points in it.
How do I do a sum across all of the same table in all the sheets?
For example I want to do Sum('Data Sheet Number *'::'Table 1'::A1) to get a sum of everything in all the A1 cells of all the sheets named 'Data Sheet Number ' followed by anything (I'm using the star in the same way one would do it in a shell...)
Thanks!

Transaction Data from multiple source systems

Hi BW,
I want to load transaction data from two source systems: SQ1CLNT100 QA and SQ1CLNT200 Training client. into one BW system. What is the best practice, do I need to create another data structure or can I mix the data for QA and training in one data structure and separate them with authorisation?
Please someone should help me out with the best practice on this.
Thanx.

Hi Dan,
Do you mean use 0LOGSYS as authorisation relevant InfoObject?
Dont you think that if I copy bid from one source system and use it in another, the two bids will have the same GUID? if that is possible, then I may be faced with the problem of data override. Please advice further.
Regards.

SPDD and SPAU Request from Multiple Source System (Dev and Quality) ??

Hi all,
We have one query related with SPDD and SPAU automatic adjustment during Upgrade.
We done SPDD in our Development systems and same is taken by SAPup during Quality Sytem PREPARE step from umauto.lst file.
But we adjusted some object in Quality System as the SPDD request from Develpopment does not able to adjust all the request. We created one request for the Same in Quality System and the that also got added to umauto.lst file.
Now during our during Mock run Upgrade, PREPARE ask to take only one system for SPDD request with following options
1. missing systems
2. Development (DEV)
3. Quality (QAS)
4. None
But we need both transport of SPDD from DEV and QAN to be imported to Mock run Systems till Production.
any suggestion to fix this ?

Hi,
Give the DEV requests for SPDD, and proceed. During DDIC_700 you will come across the DD objects which need to be corrected as you have done in QAS. here you need to open the system and correct them manually. Then only you should proceed. Be very carefull during this activity, as you may loose data if not done correctly.

How to load text data from multiple source systems.

Hello Gurus,
I am facing an issue of loading master data text into 0Material. I have loaded attribute data from 2 source systems. But i am not able load text data from the same 2 source systems as i am not able to see 0logsys in transfermation rules of 0MATERIAL.
Please gimme some inputs to proceed.
Thanks in advance
Peter

Hi,
I dont think that you need the source system info here, texts are mapped to attributs and attributs to source systems.
so try to load simply:
material key, text, lang (optional)
Hope it helps.

Parallel run of the same function from multiple jobs

Hello, everyone!
I have a function which accepts a date range, reads invoices from a partitioned by date table and writes output to a partitioned by invoice table. Each invoice can have records only with one date, so both tables may have one invoice only in one partition, i.e. partitions do not overlap. Function commits after processing each date. The whole process was running about 6 hrs with 46 million records in source table.
We are expecting source table to grow over 150 million rows, so we decided to split it into 3 parallel jobs and each job will process 1/3 of dates, and, as a result, 1/3 of invoices.
So, we call this function from 3 concurrent UNIX jobs and each job passes its own range of dates.
What we noticed, is that even if we run 3 jobs concurrently, they do not run this way! When 1st job ends after 2 hrs of run, the number of commited rows in the target table is equal to the number of rows inserted by this job. When 2nd job ends after 4 hrs of run, the number of rows in the target table is equal the summary of two jobs. And the 3rd job ends only after 6 hrs.
So, instead of improving a process by splitting it into 3 parallel jobs we ended up having 3 jobs instead of one with the same 6 hrs until target table is loaded.
My question is - How to make it work? It looks like Oracle 11g is smart enough to recognize, that all 3 jobs are calling the same function and execute this function only once at the time. I.e. it looks like only one copy of the function is loaded into the memory at the same even if it called by 3 different sessions.
The function itself has a very complicated logic, does a lot of verifications by joining to another tables and we do not want to maintain 3 copies of the same code under different names. And beside this, the plan is that if with 150 mln rows we will have a performance problem, then split it to more concurrent jobs, for example 6 or 8 jobs. Obviously we do not want to maintain so many copies of the same code by copying this function into another names.
I was monitoring jobs by quering V$SESSION and V$SQLAREA ROWS_PROCESSED and EXECUTIONS and I can see, that each job has its own set of SID's (i.e. runs up to 8 parallel processes), but number of commited rows is always eqal to the number of rows from the 1st job, then 2nd+1st, etc. So, it looks like all processes of 2nd and 3rd jobs are waiting until 1st one is done.
Any ideas?

How to read from and write into the same file from multiple threads?

I need to read from and write into a same file multiple threads.
How can we do that without any data contamination.
Can u please provide coding for this type of task.
Thanks in advance.

Assuming you are using RandomAccessFile, you can use the locking functionality in the Java NIO library to lock sections of a file that you are reading/writing from each thread (or process).
If you can't use NIO, and all your threads are in the same application, you can create your own in-process locking mechanism that each thread uses prior to accessing the file. That would take some development, and the OS already has the capability, so using NIO is the best way to go if you can use JDK 1.4 or higher.

Web Analysis : populate the same table with multiple data sources

Hi folks,
I would like to know if it is possible to populate a table with multiple data sources.
For instance, I'd like to create a table with 3 columns : Entity, Customer and AvgCostPerCust.
Entity and Customer come from one Essbase, AvgCostPerCust comes from HFM.
The objective is to get a calculated member which is Customer * AvgCostPerCust.
Any ideas ?
Once again, thanks for your help.

I would like to have the following output:
File 1 - Store 2 - Query A + Store 2 - Query B
File 2 - Store 4 - Query A + Store 4 - Query B
File 3 - Store 5 - Query A + Store 5 - Query B
the bursting level should be give at
File 1 - Store 2 - Query A + Store 2 - Query B
so the tag in the xml has to be split by common to these three rows.
since the data is coming from the diff query, and the data is not going to be under single tag.
you cannot burst it using concatenated data source.
But you can do it, using the datatemplate, and link the query and get the data for each file under a single query,
select distinct store_name from all-stores
select * from query1 where store name = :store_name === 1st query
select * from query2 where store name = :store_name === 2nd query
define the datastructure the way you wanted,
the xml will contain something like this
<stores>
<store> </store> - for store 2
<store> </store> - for store 3
<store> </store> - for store 4
<store> </store> - for store 5
<stores>
now you can burst it at store level.

Accessing the same object from multiple classes.

For the life of me I can't workout how I can access things from classes that haven't created them.
I don't want to have to use "new" multiple times in seperate classes as that would erase manipulated values.
I want to be able to access and manipulate an array of objects from multiple classes without resetting the array object values. How do I create a new object then be able to use it from all classes rather than re-creating it?
Also I need my GUI to recognize the changes my buttons are making to data and reload itself so they show up.
All help is good help!

Luke Grainger

As long as you have a headquarters it shouldn't be to painfull. You simply keep a refrence to your ShipDataBase and Arsenal and all your irrellevant stuff in Headquarters. So the start of your Headquarters class would look something like:
public class Headquarters{
public Arsenal arsenal;
public ShipDatabase db;
//constructor
public Headquarters(){
    arsenal = new Arsenal(this, ....);
    db = new ShipDatabase(...);
//The Arsenal class:
public class Arsenal{
public Headquarter hq;
public Arsenal(Headquarter hq, ....){
    this.hq = hq;
    .Then in your ShipDatabase you should, as good programing goes, keep the arraylist as a private class variable, and then make simple public methods to access it. Methods like getShipList(), addToShipList(Ship ship)....
So when you want to add a ship from arsenal you write:
hq.db.addToShipList(ship);
.Or you could of course use a more direct refrence:
ShipDatabase db = hq.db;
or even
ShipList = hq.db.getShipList();
but this requires that the shiplist in the DB is kept public....
Hope it was comprehensive enough, and that I answered what you where wondering.
Sjur
PS: Initialise the array is what you do right here:
//constructor
shipList = new Ship[6];
shipList[0] = new Ship("Sentry", 15, 10, "Scout");
" " " "etc
shipList[5] = new Ship("Sentry", 15, 10, "Scout");PPS: To make code snippets etc. more readable please read this article:
