Delta-Specific Field for Generic DataSource

Hi,
I have defined a Generic DataSource for Transaction data on R/3-Side.
This DataSource is based on View/Table EKKO (Purchasing Document Header) for some specific customer requirements. Delta-Specific Field is AEDAT (Calend. Day). Safety Interval Upper Limit is set 1 Cal. Days. No Safety Interval Lower Limit has been defined. "New Status for Changed Records" has been marked.
When we see this DataSource in Extractor Checker (RSA3), this data source
Extracted all delta data where AEDAT is not blank.
When I see the content of table EKKO, I can find few records where AEDAT is blank.
These records are missing in Extractor Checker.
How I can solve this problem? Which delta-specific field can be used in
this generic Datasource? Should I define an additional Generic DataSource with
Delta-Specific Field BEDAT (as BEDAT is filled when AEDAT is blank in table EKKO)?
Thanks for the answer.

Delta based on calday wont pick all the records which are recently posted and you can not run the delta more than one time in a day ,end of the day only you can run the delta.
Set the delta as Tme Stamp and specify the Upper limit to 5 minuts.
We can run the delta no. times and pick the documents posted in short interval of time.
With Regards,
Kishore.

Delta Specific Field for LTAP

Hi guys,
    I tried using Field EDATU Date of Pick Confirmation (First Step) as Delta - Specific Field for one of my View Datasource on Table LTAP.
    However no DELTA's recieved for the past one month
    Can someone suggest another field in table LTAP that I can use.
    Thanks

Hi Chris
I have the same issue and have not found a suitable field. Now I am doing a full load with a routine selection on a combination of QDATU and EDATU into an DSO and have a delta from the DSO to the cube. If you get sorted with teh delta, please post the solution...

Two fields for generic delta

I have to create one data source which will contain two fields for generic delta...extraction of data will be through FM.SAP provides a standard functionality to create a generic delta. This can only be build on one selected field.
The logic of the functional module is based on two fields: ICRDT (creation date) and IUPDT (change date). The module should look for both day because when a new records is created the change date does not get populated in R3.
Can anyone pls help me out?

Hello Siggi,
i have to create an delta enabled extractor for a database table.
The database table (=EAUS) contains the fields "ERDAT" and "AEDAT".
I'm a Newbie in ABAP und so i read some blogs, articles and how to do papers here.
But my tests haven't work:
1. I created a structure in SE11 for extraction. The structure contains all the of the database tabel (=EAUS)
2. Then I created a data element "ZDATE" in SE11. I integrated ZDATE in the structure.
3. Then I copied function group "RSAX" and function module "RSAX_BIW_GET_DATA_SIMPLE" in our namespace.
4. I used the copied function module as a template and adapted the coding in the function module. The coding is from the paper "Functional Module Based Delta Enabled Generic Datasource"
But i doesn't work. My deltaenabled generic datasource doesn't get the deltas. In RSA3 with update mode "D" no data records were selected. (I create new records in the database EAUS before I checked the extraction). The update mode "F" and "C" works.
Can you help me and send me the coding of your function module?
Many thanks!

IMPORTANCE OF DELTA SPECIFIC FIELD

respected all
WHAT IS THE SIGNIFICANCE OF THE FIELD"Field Nm" in the delta specific field in rso2. is this the key field for running the delta??
pls give me detaild answer as my delta is not working
thanks
abhay

Dear Mahadaya,
Here u are requesting for Generic delta
Case: the deleta filed
For example u are created one docuemnt based on created date u are getting data,if u r chenged that document when u r extracting the changed values will not be updated
if you go with (AEDAT) means document changed date automatically along with delts based on the the document change date which ever the changes are there for that document it will be reflectd
I think you under stood the concept.
It is purely based on the datasource andfunctionality which is the latest character will be updated with taht datasource that can be used.in delta update reference field.
Thanks &Regards,
Sathish

Dillema in selecting Delta Specific Field

Hi Gurus,
I have stuck in a situation and would heavily appreciate your help.
I have created a Generic datasource ZAFRU which extracting data from AFRU table.
I used Last Changed On (LAEDA) as delta specific field but later i found it is not working because more than 50% of records dont have last changed on date (LAEDA) in it.
So, later i used Posting Date (BUDAT) as delta specific field but still facing a problem. Like, suppose there is a service order which is posted three months ago but changed 5 days ago so delta will not capture the changed record as posting date (BUDAT) is not changed but only Last Changed On date (LAEDA) is changed.
In this way i am not able to use either fields as delta specific fields.
Also, can't use timestamp for delta specific field as it is not present in AFRU table and Document number also as it is blank for all the records.
Please suggest what should i use in delta specific field so that i should not miss any record in BI.
Thanks,
Saurabh

Hi Saurabh,
First enable selections for ERSDA,LAEDA,BUDAT for the datasource on this table. Create three infopackages and write below routines on ERSDA,LAEDA and use these to the DSO. Even they are repeated it won't be a problem.
Once you write below code for an infopackage on say field ERSDA so what all the confirmations created from today to past 7 days will be coming into DSO.
Similarly for LAEDA and BUDAT.... also we create another two infopackages and load similarly every time to DSO which makes that no record to be missed.
data: l_idx like sy-tabix,
      l_sdate type SCAL-DATE,
      l_edate type SCAL-DATE.
read table l_t_range with key
     fieldname = 'ERSDA'.
   l_edate = sy-datum.
   l_sdate = l_edate - '7'.
        l_t_range-low = l_sdate.
        l_t_range-high = l_edate.
        l_t_range-sign = 'I'.
        l_t_range-option = 'BT'.
l_idx = sy-tabix.
modify l_t_range index l_idx.
p_subrc = 0.

Dont have a delta specific field

Experts,
We dont have a single char to mention in "Field Nm".We are using a table for Generic Datasource.Can we create a new field in the table and use it in "Filed Nm".
If you have any suggestion.Plz tell me the navigation steps also or provide me the doc.
Points will be assigned.

Dear K V,
Kindly mention the BI version on which you are currently working.
Timestamp or date in delta is meant towards the delta management and need not relevant for Business reporting. delta related date or time are basically to check latency of data. I guess here yoyu are getting confused a little bit.
Reporting relevant dates are not usually a basis for delta management. Let me put an example in case of purchasing, there used to be document date. posting date, schedule delivery dates etc, all these dates are also stored normally in a single database table. These dates are either a current dates or historical or in future based on their business pespective, so used for business reporting. This information is stored in the database at different field in the record. This record has its metadata, which mentions information about himself, this information consists of created by, created on, changed by, changed on.
My dear friend, Out of this metadata, date residing in changed on is relevant for us. so please check in your z table about where this record changed on date is populated, and use for your delta build up.
So now search for the information I told to you.
Despite this, if u did not get any date directly then pick up date part from timestamp into the variable (type date) and then make this field as a basis for your delta.
hope this will show u path to get it done.

Delta method preferable for generic data source

Hi All,
I'm working on APOBW ,i need to pull primary sale data into apobw .So ABAP er created a program to pick the data from tables vbrp,vbrk,knvv,mara,marc,t179 and populating into a transparent table.I have created a generic data source using that ztable and then loading data to infocube in APOBW.I need to pull data daily twice.I have fields data and time in the Z table.
Please suggest me how to pull the delta data and let me know if DSO is needed in between before loading to Infocube.
Thanks.

Hi,
For Enabling Delta, while creating the Generic Datasource you have an option of Enabling it to be Delta capable. Select Generic delta at the top and then you would see 3 options of how you want to get your delta records.
It is based on
1) Timestamp
2) Numeric Pointer
3) Calendar Day
Depending what you have in your Table, you can select on what your delta would be based.

How to set Non Cumulative Init flag for Generic datasource

Hi all,
I need to create a generic datasource which can be used to initialize the Non Cumulative Cube. Eg. setting the opening balance.
The STOCKUPD field in the ROOSOURCE should be set to X so that the infopackage will have the "Generate Initial Status" option. But there is no interface available in R/3 pluggin to do this.
How can this be done? Or is it not allowed for generic datasources as it is only valid of 2LIS_03_BX datasource
for stock updation.
Will there be other issues if I change the table entry for STOCKUPD in roosource table for my datasource?

Enabling Early Delta Initialization option for LO DataSource 2LIS_06_INV

Hi Guyz,
I want to enable Earlt Delta Initialization option for LO DataSource 2LIS_06_INV, as of now its greyed out.
please tell me if its possible or not, and if yes then please let me know the steps in detail.
cheerz,
raps.

hi,
Not all Data sources support Early Delta Initialization. Early delta initialization is done to capture the deltas when the initialization is being done between BW and source system (init with data transfer). As init with data transfer takes large time and during this time any records created will also be not captured so we do early delta initialization, also the same can be achieved by executing the init without data transfer and then loading a full repair request. The init without data transfer creats a time stamp and delta is generated for newly posted records.

Arvind.

Delta field for generic data source based on view EKBE

Hello,
I am creating a generic datasource based on table EKBE. Can anyone please tell me what field should I use for delta. Is it BUDAT(Posting Date in the Document) or CPUDT(Day On Which Accounting Document Was Entered).
Thanks for the help.
Praveen

Hello Ajeet Singh,
Thank you very much for the reply.
I will go ahead with CPUDT.
BUDAT is the date which can be changed. I can change the date in system and chances are it will not pick in delta.
CPUDT is the date on which document was created/changed.
Thanks,
Praveen

Field in Append Structure for Generic Datasource

Hi:
I created a Generic Datasource based on a view. After that, I created an Append to the Extraction Structure to include a field not originally on the view (and not related to any table in the view) to be calculated using customer exit in CMOD.
At the moment of activating the Datasource, this new field doesn't appear in the selection window but in RSA6 it shows there with options "Hide Field" and "Field only Known in Customer Exit" checked.
Again, I try to edit the Datasource but this field is not in the list to change those two checks.
Any idea?
Thanks.
Luis Sales

Dear Luis Sales,
I was having the same requirement. I tried it hard for removing the tick mark on the HIDE option. But it was not working at all.
I tried these steps.
1. From RSO2 went to Extract structure. Edit Mode-> append structure.
2. Appended required fields and activated both append structure and extract structure.
3. Back to datasource and Save it.
4. Came out of transaction RSO2. ( latter Logged of system )
5. after re login - RSA6 selected given Datasource and change. there I could change the selection of HIDE field. ( Even earlier I was not able to do that)
May be these steps help you out.

Delta on Sales Data (Generic Datasource)

Hi,
I have created a generic datasoucrce which is taking data from VBRK & VBRP. Now i have to set delta on it, for which i was looking for change date field but didnt found anyone.
Does anyone have any idea on which field for sales data i can set my delta ??

Hi,
generic extractor is an extractor that you create yourself for a special requirement which is not solved by the standard available business content.
Before creating your own datasource take a look at the Logistic Cockpit (Transaction LBWE) -> application 13. Here you found BW content datasources like 2LIS_13_VDITM
to extract the tables for SD billing document (VBRK & VBRP) in delta mode.
After you have filled the setup table for application 13 you can do an initial run from BW. Now you can extract your delta without building your own datasource. Delta updating is part of the standard Logistics extraction process.
Additional you can use now standard business content in BW system for this extraction (or take a look on it how it is implemented).
Check this blogs for Logistics Extraction:
