Problem in creating a generic datasource with infoset

Dear Expert,
I have to create a generic datasource with infoset. I linked the infoset with a test program below. In the program, I have one selection option, which is s_order. After creating an infoset and a datasource, this selection option 'SELECT_S_ORDER' is added to my extract structure. However, after try filtering with this SELECT_S_ORDER, it doesn't filter data at all. Why? I want to filter data with my s_order.
REPORT ZBI_DS_TEST.
tables: vbak.
* DATA
field-symbols: <vbak> type vbak.
data:   t_vbak      type table of vbak,
            w_vbak     type vbak,
            t_vbak2    type table of vbak,
            w_vbak2    type vbak.

   endloop.

*      Select data

    select *
    into    table t_vbak
    from   vbak
    where vtweg = 'IP'.
ENDFORM.                    " sub_select_data

What do you mean by linking program with infoset?
Do you get the field in your RSA3 Tcode?

Generic Datasource with Delta and functionmodule

Hi together,
who can help me ??
Ihave created a generic datasource with function module and
delta.
the extractor runs well while i use full update and also initialization.
If i start the delta extraction, the extractor crashed with short-dump.
the message is SAPSQL_INVALID_FIELDNAME
What can i do, and what is wrong.
regards

Generic Datasource with Fuction Module with delta on Created Date

Hi Experts,
I have created a generic datasource using Function Module RSAX_BIW_GET_DATA. I have copied this function module and created a my own Function Module. I want to load delta using this. But I don't know how to handle delta in the code.
my code is working for full load but not for delta. I have seen that in ROOSOURCE tabel the Delta field is showing the AIE instead of D and extraction method is showing as F2. I have searched a lot of forums and articles but didn't get how to handle this.
Please advice.

Hi Amit,
Go through the link as suggested by AKhan which lets you understand the concept of offsets and the last extraction status.
In case of Table or View based GDS, the system takes care of the deltas based on the selections you make in the "Generic Delta" screen whereas in case of FM based DS, it is your responsibility to handle this part. Within your code, capture if the load is a Delta load (I_UPDMODE = D). Since your delta is on Created Date, maintain a Z table with name of the DS as the Key and a field representing the current value of the Delta field(created date in this case). When you first load the delta, there will be no record for your DS in this table. Create an entry with the current day. Next time when you load a delta, take this value, compare it with sy-datum and get all the records falling within these days. This has to be done in the Select stmt. Once selection happens, replace the value in the Z table with sy-datum. This way you can simulate the delta. The Z table can be used for other FM based Datasources also as it has DS as the key.
It would be easy if the exact SAP table where RSA7 delta field status is stored is known. Otherwise, the above method can be used.
Revert for any further queries.

Generic datasource with Delta queue

Hi All,
I 've created a generic datasource on prices tables A* and KONP. Next, I used HowTo document "create generic datasource that uses delta queue", finding the right BTE that could catch prices modification. Up to this point, everything works fine.
I've extracted an Init delta to BW and now, on R/3, in RSA7, I can see a delta queue for my generic datasource.
When I modify price conditions in VK12, BTE works fine and I can see the counter in RSA7 increasing. I also can see new entries in table TRFCQOUT with status READY. (either in SE16 or in SMQ1 )
The problem is :
- in RSA7, if I want to display the posted data, system returns an empty list (whereas the counter is different from 0)
- when I run a delta InfoPackage, no data is sent to BW, but in table TRFCQOUT, status has been changed to READ for entries that previously had status READY (and old entries that had status READ due to a previous delta upload are deleted)
Does anyone has any idea about the reason of the issue ?
Thanks for any help
AJ

Sure, I can.
The problem was in the specific coding that update the delta queue : not all the fields were updated and some of these fields were used as selection criteria in th delta infopackage...
in RSA7, when you try to see the data in the queue, the system only shows you the records that match the selection criterias of your delta IP...so in our case, because of those empty fields, no records were selected...

How to create a generic datasource from function module?

Dear experts,
I have created a generic datasource from function module. For this extrator, I created a function module and a structure.
I have now some difficulties to continue:
In this function module, i get data from different transparent tables. Then i put these data into an internal table.
I just don't know what is the relatioin between the structure i defined and this internal table.
I should make "iTab structure AA" in the source code?
Thanks

1. Create s structure with the fields that you need from the 4 tables . Activate.
2. Goto SE 80 Select The Function Group , Copy , Select the Function module
" RSAX_BIW_GET_DATA_SIMPLE " and Give a New name starting With
Y or Z .
3. SE37 ->Your Function module name -> Change , In table tab give your structure
name by deleting the associated type given in " XXXX " .
4. Now select source code and Do the coding . Give Data source name in Coding .
In your case you have to take data from more that 1 table .
5. Activate the Function Group .
6. In RSO2 Create the Data source , Give the Function Module Name , And Save.
7. RSA3 -> Give data source name and Check for the Records .
Creation of custom datasource. (Using function module)
.Create a function group .
. Structure ZTXXXX
Create function module (i.e. ZTESTXXX) .
. Create the data source using transaction (RSO2).
. If structure exists for the table parameter of your function module then ok else create a structure for the table parameter .
Test the datasource in R/3 using transaction RSA3.
Transfer the data source to BW System and replicate it in the BW-System.

Generic datasource with FM

All;
We need to do live cache extraction for APO data. How do we set up that in BW? Is this done using generic datasource with a Function module? Can anyone give me some ideas?
Thanks,
Manasa.

Hi,
In the Extractution structure you need to put the two dates and mark both like selection parameter.
This is the template for Generic FM Extractors "RSAX_BIW_GET_DATA_SIMPLE" to create the FM.
Follow the FM Code, in the part of the first execution you need to do two loops (one for every date).

Dani

Hi all
I have a question.
In whic case can I use a generic datasource with additive delta?
Does this delta mode make sens only with function module extraction?
If I extract data directly from a table, can I use this delta mode only if a field represents changes?
Thanks for your help!

Stefania,
    To my knowledge what you are thinking is wrong.
we have 2 Methods for Generic DS.
1. New status for changed Records.
2. Additive delta.
New status for changed records means
New Order
order no    quantity
1000          10
order changed to quntity 8. then 2 records will posted 2 BW in first case.
1000          -10
1000            8
if you come to Additve delta.
for the same case it will send the same record as
1000          10
changed records
1000          -2
this is the difference. New status with changed records should be used only in association with ODS not cube becoz we don't have overwrite option.
Additive delta we can use for ODS and Cubes with update mode Addition.
Hope this is clear.

Generic DataSource using InfoSet on BI 7.0

Hi gurus,
I need to extract data from a InfoCube through a generic DataSource. I have created an InfoSet Query based on this InfoCube and I have noticed this kind of InfoSet is not the same that is used by Tcode RSO2.
Does anybody know if there is any way to get this vai generic DataSource?
I need to get data from Infocube because de Delta Control must be the package number.
Thanks in advance,
Silvio Messias.
P.S.: The version of my environment is 7.0.

Hi Ashok,
Into the Tcode RSO2 (Generic DataSource) I have the option to collect data from an InfoSet. This InfoSet must be created through Tcode SQ02, right?
I woult like to get data from a Infoset Query based on InfoCube, created through RSA1 on BI 7.0.
Is there any way to do it?
Thanks for your help,
Silvio Messias.

Problem in creating a Generic Extractor on a custom 'Z' table

This is regarding an earlier question I posted in sdn today. I am trying to create a generic extractor on a custom 'Z' table and iam getting the following message.
Invalid extract structure template YBW_Z3PVR of DataSource YCNA_3PVAR_RPT
Message no. R8359
Diagnosis
You tried to generate an extract structure with the template structure Z3PVR. This operation failed, because the template structure quantity fields or currency fields, for example, field MENGE refer to a different table.
Procedure
Use the template structure to create a view or DDIC structure that does not contain the inadmissable fields.
Please advise. how do i solve this?

Hi there,
Is your Z* table working? It must be add check field for quantity field and currency field.
Hope this helps.

Problem in creating a CMP bean with MySql

Hi,
I am using lomboz eclipse, jboss 4.0.2, xdoclet 1.2.3 & DB as MySql 5.0. I am encountering a very strange problem when I try to create a CMP with MySql as DB. After entering relevant information about the datasource & testing the connection & finding it to be successful, I get the error in lomboz eclipse as : CMP has no attributes. Moreover, I donot even get the table names from the schema, that was given in the datasource, with which the mapping of my CMP will be done.
I tried using Oracle 9i. But to my wonder, I didnot experience this issue, as it gave me all the CMP atttributes mapped & also created the CMP with Oracle DB. Can anyone help me in getting this issue resloved with MySql DB?

Yeah, the DB User permissions are found to be ok, as the test connection was successfull. I have tried for MySql 4.1 & Myql 5.0, with their respective jars & driver classes. But the result was same. Test connection is successful, but when i hit the next button to see the CMP attributes, it doesnot give me the list of tables under that schema & says that CMP has no attributes. Please help.

Generic datasource with function module

I am trying to create a transactional generic datasouce with fm.
I create my structure ZNVBAK1, create a function group ZRSAX, a FM ZRSAX_BIW_GET_DATA_SIMPLE1 and I adjust my source code.
I activated both FM and Function Group.
Now under RSO2 I enter the datasource name as in my code, I enter the application component SD as well as the description
When I choose extraction by FM, nothing happens, no windows prompting me to enter my function module as well as extract structure, I checked everthing look good.
Any Idea what I might be doing wrong?
Thanks!!

Hi ,
First put values in Short Description, Medium Description & long Description,fields and then click on the Extraction by FM. You will get those filelds unabled.
You can also refer.
