Data load / Collection of R/3 Table filelds to BW

Hi,
Here is the situation...I have to pull data from sap R/3 tables like VBRP, VBAK,VBKD TO BW on monthly basis. Can anyone of you gurus tell me what I have to do, to load these data from R/3 to cube in BW. Can you please help us by step by step procedure in detail way like the Basic steps we have to do and steps to do in BW..
Thanks,
David

Hi David,
You could do this in 2 ways:
Either by using SAP delivered standard data sources i.e. 2LIS_13_VDITM and 2LIA_11_VAHDR. Or by creating Generic extractor either using Views or function modules.
If you decide to use SAP delivered standard extractors then you can see them in RSA5. Activate those and you can use them. You can test in RSA3 extract checker.
If you decide to use generic extractor then go to RSO2 and create a data source of your own with necessary fields.
Once this is done in R/3 side, you can check the data in RSA3 extractor checker.
Now in BW side replicate the data source in your source system.
Create transfer structure, communication structure then cube. Join the cube and transfer structure with update rules. Mappings should be clear.
Create info package and schedule the job.
Hope this helps you,
Bye,
Naga.

Open HUB ( SAP BW ) to SAP HANA through DB Connection data loading , Delete data from table option is not working Please help any one from this forum

Issue:
I have SAP BW system and SAP HANA System
SAP BW to SAP HANA connecting through a DB Connection (named HANA)
Whenever I created any Open Hub as Destination like DB Table with the help of DB Connection, table will be created at HANA Schema level ( L_F50800_D )
Executed the Open Hub service without checking DELETING Data from table option
Data loaded with 16 Records from BW to HANA same
Second time again executed from BW to HANA now 32 records came ( it is going to append )
Executed the Open Hub service with checking DELETING Data from table option
Now am getting short Dump DBIF_RSQL_TABLE_KNOWN getting
If checking in SAP BW system tio SAP BW system it is working fine ..
will this option supports through DB Connection or not ?
Please follow the attachemnet along with this discussion and help me to resolve how ?

Santhosh Kumar

Hi Ramanjaneyulu ,
First of all thanks for the reply ,
Here the issue is At OH level ( Definition Level - DESTINATION TAB and FIELD DEFINITION )
in that there is check box i have selected already that is what my issue even though selected also
not performing the deletion from target level .
SAP BW - to SAP HANA via DBC connection
1. first time from BW suppose 16 records - Dtp Executed -loaded up to HANA - 16 same
2. second time again executed from BW - now hana side appaended means 16+16 = 32
3. so that i used to select the check box at OH level like Deleting data from table
4. Now excuted the DTP it throws an Short Dump - DBIF_RSQL_TABLE_KNOWN
Now please tell me how to resolve this ? will this option is applicable for HANA mean to say like , deleting data from table option ...
Thanks

Is it possible to upload few column in table through Apex Data Loading

Hi All,
I have to do upload into the table through a csv file . The table's primary key i have to load the rest through user's uploaded file. Is it possible to do the data loading to the table only to required columns and fill the other columns from backend. Or is there any other way to do this?

Hi,
Your query is not really clear.
>

How do you plan to "link" the rows from these 2 sets of data in the "backend"? There has to be a way to have a relation between them.

Loading data from .csv file into existing table

Hi,
I have taken a look at several threads which talk about loading data from .csv file into existing /new table. Also checked out Vikas's application regarding the same. I am trying to explain my requirement with an example.
I have a .csv file and I want the data to be loaded into an existing table. The timesheet table columns are -
timesheet_entry_id,time_worked,timesheet_date,project_key .
The csv columns are :
project,utilization,project_key,timesheet_category,employee,timesheet_date , hours_worked etc.
What I needed to know is that before the csv data is loaded into the timesheet table is there any way of validating the project key ( which is the primary key of the projects table) with the projects table . I need to perform similar validations with other columns like customer_id from customers table. Basically the loading should be done after validating if the data exists in the parent table. Has anyone done this kind of loading through the APEX utility-data load.Or is there another method of accomplishing the same.
Does Vikas's application do what the utility does ( i am assuming that the code being from 2005 the utility was not incorporated in APEX at that time). Any helpful advise is greatly appreciated.
Thanks,
Anjali

Hi Anjali,
Take a look at these threads which might outline different ways to do it -
File Browse, File Upload
Loading CSV file using external table
Loading a CSV file into a table
you can create hidden items in the page to validate previous records before insert data.
Hope this helps,

Comparison of Data Loading techniques - Sql Loader & External Tables

Below are 2 techniques using which the data can be loaded from Flat files to oracle tables.
1)     SQL Loader:
a.     Place the flat file( .txt or .csv) on the desired Location.
b.     Create a control file
Load Data
Infile "Mytextfile.txt" (-- file containing table data , specify paths correctly, it could be .csv as well)
Append or Truncate (-- based on requirement) into oracle tablename
Separated by "," (or the delimiter we use in input file) optionally enclosed by
(Field1, field2, field3 etc)
c.     Now run sqlldr utility of oracle on sql command prompt as
sqlldr username/password .CTL filename
d.     The data can be verified by selecting the data from the table.
Select * from oracle_table;
2)     External Table:
a.     Place the flat file (.txt or .csv) on the desired location.
abc.csv
1,one,first
2,two,second
3,three,third
4,four,fourth
b.     Create a directory
create or replace directory ext_dir as '/home/rene/ext_dir'; -- path where the source file is kept
c.     After granting appropriate permissions to the user, we can create external table like below.
create table ext_table_csv (
i Number,
n Varchar2(20),
m Varchar2(20)
organization external (
type oracle_loader
default directory ext_dir
access parameters (
records delimited by newline
fields terminated by ','
missing field values are null
location ('file.csv')
reject limit unlimited;
d.     Verify data by selecting it from the external table now
select * from ext_table_csv;
External tables feature is a complement to existing SQL*Loader functionality.
It allows you to –
•     Access data in external sources as if it were in a table in the database.
•     Merge a flat file with an existing table in one statement.
•     Sort a flat file on the way into a table you want compressed nicely
•     Do a parallel direct path load -- without splitting up the input file, writing
Shortcomings:
•     External tables are read-only.
•     No data manipulation language (DML) operations or index creation is allowed on an external table.
Using Sql Loader You can –
•     Load the data from a stored procedure or trigger (insert is not sqlldr)
•     Do multi-table inserts
•     Flow the data through a pipelined plsql function for cleansing/transformation
Comparison for data loading
To make the loading operation faster, the degree of parallelism can be set to any number, e.g 4
So, when you created the external table, the database will divide the file to be read by four processes running in parallel. This parallelism happens automatically, with no additional effort on your part, and is really quite convenient. To parallelize this load using SQL*Loader, you would have had to manually divide your input file into multiple smaller files.
Conclusion:
SQL*Loader may be the better choice in data loading situations that require additional indexing of the staging table. However, we can always copy the data from external tables to Oracle Tables using DB links.

Load data from flat file to target table with scheduling in loader

Hi All,
I have requirement as follows.
I need to load the data to the target table on every Saturday. My source file consists of dataof several sates.For every week i have to load one particular state data to target table.
If first week I loaded AP data, then second week on Saturday karnatak, etc.
can u plz provide code also how can i schedule the data load with every saturday with different state column values automatically.
Thanks & Regards,
Sekhar

The best solution would be:
get the flat file to the Database server
define an External Table pointing to that flat file
insert into destination table(s) as select * from external_table
Loading only single state data each Saturday might mean troubles, but assuming there are valid reasons to do so, you could:
create a job with a p_state parameter executing insert into destination table(s) as select * from external_table where state = p_state
create a Scheduler chain where each member runs on next Saturday executing the same job with a different p_stateparameter

Where Clause in Table Lookups for Data Load

Hello,
In Shared Components I created in Data Load Table. In this Data Load Table I added a Table Lookup. On the page to edit the Table Lookup, there is a field called Where Clause. I tried to add a Where Clause to my Table Lookup in this field but it seems that it has no effect on the Data Load process.
Does someone know how to use this Where Clause field?
Thanks,
Seb

Hi,
I'm having the same problem with the where clause being ignored in the table lookup, is this a bug and if so is there a work around?
Thanks in advance

How to update existing table using Data Load from spreadsheet option?

Hi there,
I need to update an existing table, but in Data Load application when you select csv file to upload it inserts all data by replacing existing one. How can i change this?
Let me know,
Thank you.
A.B.A.

And how do you expect your database server to access a local file in your machine ?
Is the file accessible from outside your machine say inside a webserver folder so that some DB process can poll on the file ?
Or, is your DB server in the same machine where you have the text file ?
You will have to figure out the file acess part before automating user interaction or even auto-refreshing.
