Create generic extractor based on 2 tables

hey BI gurus,
I have to create a generic extractor based on these 3 tables:
eban - i need all fields
vttk - i need only 4 fields i.e
                                     route,
                                     tknum,
                                     datbg,
                                     daten
ekbe - budat.
now the problem is thr is no common field between vttk & eban AND vttk & ekbe. but thr is a common field between eban & ekbe.so i can create a view only on these 2 tables but i want 3 tables
how do i proceed???

Hi,
Sometimes, if your application or requirement makes it necessary, you have to create your own function module to extract the data from whatever sap system to bw.
Therefore you normally make a copy of the standard fm 'RSAX_BIW_GET_DATA_SIMPLE'. To make this new function work for you, you have to realize the following.
1.) the fm gets called by the extraction api for at least 2 times. First time is for initialization and from the 2nd time on it is for data extraction.
2.) right after the last data package (somehow you need to make sure that it is the last one) you have to raise the exception no_more_data.

Missing new fields in generic extractor but present in table view

Hi
I can't see new fields in generic extractor but they are present in the table view.
Few days ago I created a generic datasource based on table view. Now I included 2 more fields in the table view but these fields doesn't show in RSA6 and RSO2.
how can i resolve this.
thanks

Hi Bhat,
GO to RSA5 and give ur generic extractor name ....
Click on edit the newly added fields will be hided ...so u need to uncheck the hide olumn
once this is done save that.
U will find the fields in RSA3 and RS02

Error while creating Generic Extractor via Function Module

Hello Guys
I have created a Generic Extractor through a Function Module. I took the Standard FM: RSAX_BIW_GET_DATA_SIMPLE, gave it a new name and activated it. I made a few changes in it, like giving my structure name for E_T_DATA and giving the list of tables, from where I need to get the data. Then I created the datasource in RSO2 by giving this function module and the extract structure.
The DS was created properly, but when I check in RSA3 for records, its giving me an error: ---> <b>The extraction program does not support object YCNA_INVY_TRNS</b>
What do i do now? Can someone please tell me, what changes I need to make in the standard FM to suit my requirements??
Thanks.

Hi,
Just try to reactivate the structure once again. And when you open the function module, if the problem still persists just try to press Return key several times. The message you are getting is just a warning message.
PS: I am not sure whether this is the correct way, but i personally resolved this by pressing the ENTER key 4 or 5 times. So just give a try.

Parth Kulkarni,
following the note and the other thread, I've check the index 4 of the table COEP.
Here is what I got:
Index ID           COEP             - 4
Short text         MANDT/TIMESTMP/OBJNR, Index for Delta read method (CO-PA)
Last changed       SAP             04.01.2010
Status             Active          Saved
                   Does not exist in the database
DB index nme
    Not defined as DB index in the ABAP Dictionary
Is the fact that it doesn't exist in the database a problem ?
Is the fact that it is active is good enough ?
By the way thanks for your speedy reply !

Generic datasource based on custom table and hierarchy table

Hi Gurus,
I have a doubt regarding generic datasource.
my requirement: to create a datasource with 10 fields. (7 fields from custom table and 3 fields whose values can be derived from a hierarchy table).
I have a custom table. In this table one field refers to a hierarchy table. Using this hierarchy table, we can derive values to 3 new fields.
My question is, If i create a generic datasource based on the custom table, how can i include the extra 3 fields which gets values from the hierarchy table.
Where can i write the logic to extract the values for those 3 fields from the hierarchy table.
Thanks
Regards,

Hi Aarthi,
Sample code in the user exit woul be like this:
DATA: i_biw_tab LIKE BIW_MARA_S.
WHEN '<data source>'.
    LOOP AT i_t_data INTO i_biw_tab.
      SELECT fields
        INTO <table from which you want the value
        FROM <table>
       WHERE <your condition>.
      IF sy-subrc = 0.
             MODIFY i_t_data FROM i_biw_tab.

The Generic Extractor DataSource's TimeStamp table?

We known the FI DataSource has the TimeStamp table BWOM2_TIMEST which provide two fields TS_LOW and TS_HIGH to store the Safty Interval information. I think the Generic Extractors DataSource may has the similar TimeStamp table too. If it is right, where is the TimeStamp table to Generic Extractors DataSource? Thanks for your reply.

Many thanks for all of you. I have checked the tables and data flow.
The result is below,FYI
Field comment
ROOSOURCE-OLTPSOURCE (The DataSource name)
ROOSOURCE-DELTASAFE1 (The Safety Interval Lower Limit)
ROOSOURCE-DELTASAFE2 (The Safety Interval Upper Limit)
ROOSOURCE-TSTPDAT (The DataSource create date)
ROOSOURCE-TSTPTIME (The DataSource create time)
ROOSGENDLM-OLTPSOURCE (The DataSource name)
ROOSGENDLM-DELTAID (The Current Delta update Timestamp)
ROOSGENDLM-REPEATID (TheLast Delta update Timestamp)
RSA7->Current Status (The Current Delta update Timestamp)

How to create SAP Extractor based ODP on Hana?

Hi SAP Gurus,
I am a HANA begginer and trying to create an SAP extractor based ODP.
Till now i have created a source system under "ODP - SAP (Extractors)" node of source system screen. I didn't enter any source system and type because there was no choice in the help list.
Connection test and authorization test through sm59 are working with no problem.
In the source system i activated datasource 0FI_GL_4 and made sure that's working through rsa3 . I can retrieve more than 1000 line of data. So everything seems alright but when i try to replicate data source in HANA system i got this error;
"Destination DTYIDS_IDS_00: ping waiting time (5 seconds) exceeded
Message no. RSDS571"
Some information on this issue and latter steps in order to create an ODP will be greatly appreciated.
Best regards,
Yağız

Reg : delta field for vbbe table while creating generic extractor

hi
i want to know which field should i use to do delta from vbbe table.
do i have to ask my functional consultant for what field should ibe using or
should i decide on my own
your answer would be defintely rewarded
thanks a lot
pallavi

Hi,
I would suggest you to create a new sales document and try to find out how does it the new entry is entered in VBUK, VBUP, VBEP and VBBE tables. Also, try to change / modify and delete existing record and see the changes in the table. You need to check which date fields or any deletion indicator is set / modified or not. Do all this one by one and see the changes in the tables. Also, all these changes will be logged in change log table such as CDHDR and CDPOS. This will have all the history of changes for one sales document. Once you identify all this then it will be very easy for you to identify the delta fields. The other way is to speak to functional consultant and ask him how all these tables are affected when you change / modify / add / delete records.
Hope this helps.

Generic extractor based on specific function module with delta update

Hi,
first of all: The use of delta in a generic Datasource by FM is not supported by SAP standard. You need to change the extraction method in table ROOSOURCE from F2 to F1. There is no standard transaction to do this, you have to do a hard table update. Be careful not to change any standard datasource by error, otherwise you can get serious problems.
The interface for the FM will change with the new extraction method. You will need a new parameter I_UPDMODE of type SBIWA_S_INTERFACE-UPDMODE to distinguish between Init, Delta and Full Load.
For an example coding please refer to FM RSVD_BW_GET_DELTA_DATA.
Hope that helps

Error while creating a extractor based on Functional Module

Hi,
I am building an extactor based on afunction module.I created a DS and created a structure in Se11.When i am trying to put the extract structure in the Tables tab of the function module it gives me an error saying Tables parameters are obselete and doesnt allow me to activate or go back and front to other tabs.Can anyone please tell me what might be the reason?
Thanks,

Hi,
Just try to reactivate the structure once again. And when you open the function module, if the problem still persists just try to press Return key several times. The message you are getting is just a warning message.

Can I create a view based on two tables that have the same column name?

I have two tables A and B. Each table has 50+ columns.
I want to create a view that includes all the columns in A and all the columns in B. I created a view with a select statement that says
Select A.*, B.*
From A, B
where A.id = B.id
It returns an error because in each table I have a column that keeps track if a record has been changed called Modified_By. That's where it chokes up on I figure. I would like to write the view without explicitly writing each column name from A and B as part of the select statement. The actual select statement works fine and only bombs when trying to turn the select statement into a view.

You will have to type the full column list at least once. You can save a few keystrokes (i.e. alias. on every column) by providing the column names to the CREATE part instead of in the SELECT part. Something like:
SQL> desc t
Name                                      Null?    Type
ID                                                 NUMBER
NAME                                               VARCHAR2(10)
SQL> desc t1
Name                                      Null?    Type
T_ID                                               NUMBER
LOC_ID                                             NUMBER
NAME                                               VARCHAR2(15)
SQL> CREATE VIEW t_v (id, t_name, t_id, loc_id, t1_name) AS
2 SELECT t.*, t1.*
3 FROM t, t1
4 WHERE t.id = t1.t_id;
View created.HTH

Dynamically create a class based on database tables

I am trying to build a database and tables on the fly, and save to the harddisk(done). Then I need to create a class using the info from the tables on the fly.
For example,
I built a database BANK, and a table Customer,
Customer
ID
Phoneno
Address
Could I create a class named CUSTOMER (table name)
dynamically, and have ID, PHONENO, ADDRESS,as the attributes of the class?
Could anyone help or show the direction?
Cheers.

You could use a HashMap, and use the String keys "Customer", "ID", etc, and if you have primitive values like an int, you just wrap it inside Integer or any of the other wrapper classes, because HashMap only works with objects.
Then you can use an ArrayList to hold all the records (one record is one HashMap as described above).

Generic Extractors for HR Reports using views and Infoset Query

Hi Friends... I am working to come out with the HR reports in BW for the HR reports which are already there in R/3. The HR reports in R/3 are created based on Infoset Query.I could not find any standard business content cubes which can give me these reports.
1)So please can anyone give me step by step approach so to create a generic extractors based on Infoset Query.
2)And also how to populate the data into the fields of the generic extractor which is created by Infoset Query( Please provide any sample ABAP code if available)
3)can anyone give me step by step approach so to create a generic extractors based on View/Table.
4)And also how to populate the data into the fields of the generic extractor which is created by View/Table( Please provide any sample ABAP code if available)
Thanks

Hi Kalyani,
We normally go for View or infoset when the data to be fetched in BW is distributed in different tables in SAP R/3.
Had the data been available in one table we can easily build our datasource on that table but if there are more tables then its not possible to do it without Views or Infosets. You can use Function Modules to build your datasource in case it involves complex logic to figure out the data from various tables.
Depending upon the table relationships we create view and include various fields from these tables in that view. Same is with the Infosets, you can have more flexible options like Outer Join, left outer Join etc.

Pratap Sone

Generic extractors on pool table and Cluster tables

Good Afternoon all,
Can we create generic extractors on Cluster or pool Table. If yes Let me know how?
I am trying to create a Generic Extractor on BSEC Table but it is not allowing me to do this. It throws error that"Extraction from pool tables and cluster tables is not permitted"
Kindly guide me on this
Thanks,
Vaishali.

Hi
you cannot do generic extraction directly on pooled or cluster tables.
You can create a function module, then you can create a Generic Data source based on this..
Hope it helps,
Thanks,

Error creating form based on a table

This is wierd. I am running WebDB2.2

creating forms from tables. But now in

the error below. I have assigned SUMI
almost every possible permission
