Changing a generic datasource

Hi all,
I already have a datasource which is created through view which is already available in production.Now we want to just add a field and we have for it in he view table itself.Can someone tell my the steps how to do it.I have done it and i can see it in the view but not in the datasource.
Regards,
Harish

Hi kiran,
I cant see the field at all in RSO2
I entered my datasource in RSO2,Inside in cam find 2 options under extraction from DB view which is 1.View/Table , 2.Extract struc.
In option 1 when i click my view i can see the added field.
In option 2 i cant see my field in the extact struc.
Please guide me how to proceed.
Thanks
Harish

Generic Datasource Delta Settings Change

Hi Experts,
Currently the delta field in generic datasource is set to timestamp (LOCAL) and Upper limit is blank.
I need to change the delta settings to timestamp(UTC) or set the upper limit to 1000 seconds.
Can anyone tell me how to change this in production. Do i need to change this in dev and transport this to production.
If i do the changes to generic datasource, do i have to initialise the delta again?
Pls provide me the step by step solution.
Regards,
Anand

Ananda, What about the delta initialization? After transporting the datasource from R/3 dev to R/3 production, I have to replicate the datasource right.
In that case what will happen to my delta?.
One more thing incase i need to change only the upper limit value. Even for this, do i have to change it in dev and transport to production?

Anand

Generic Datasource on table IMRG in R/3- delta on timestamp is it ok ?

Hi
I am creating Generic datasource based on table IMRG in R/3, This has stoppages related data. which we need in BI report. There is a field for Time-stamp in the table, i have checked values in table IMRG, but in R/3 it shows no data for the time-stamp.
Now i want to create delta basis for this generic datasource based on table, so shall i create delta based on time-stamp or date field.
If I create delta based on time-stamp will it create problem in delta extraction subsequently? Please share your experience in such a cases.

There is a field for Time-stamp in the table, i have checked values in table IMRG, but in R/3 it shows no data for the time-stamp.
Delta specific field should be something which defines changes in your table, not something which is blank always.Based on the change in this delta specific field only delta will be pulled.Having it blank will never pull you delta.
Hope this helps.

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

Horizontal Bar in the RSA3 is not showing up for Generic Datasource.

Hi There,
Created a Generic Extarctor based on a two tables PAYR and REGUH.
Included 60 fields in the Generic datasource. Everything is fine and when i check the data in extract checker
RSA3, the horizontal bar is not showing up and i could only see 15 fields. I couldn't able to see the rest of the fields.
Can someone suggest what should i do to see all the fields in RSA3? Why Horizontal bar is not showing up?
Out of 60 fields only very few are hidden and it should show atleast 40 fields, but not happening..
Thanks
Vandana

HI There,
Thanks for all your responses.
1 - Tried to change the layout by going into Menu Settings --> Layout ---> Current, but no option to change.
2 - If I check the value of a particular field in the magnifier, then I could able to see all the fields
3 - After executing the RSA3, tried to change to ALV Grid by going into LIST, but again no option available to change.
4 - Checked the RSA2, and to my surprise all the fields are ticked as Key. Is that something why i'm able to see all fields in
     the browser?
5 - But when the check the datasource in RSA6, only 3 were ticked as Key and those three fields i can see before
     extracting the data using extract checker RSA3.
6 - Why all fields are ticked and showing and Key in RSA2 ?
The above is the current status of this issue. Can anyone please suggest how i should go head?
Thanks
Vandana

How to deal with delete record in generic delta of generic datasource

Hi,
Anyone can give me suggestion about the delete record in generic delta of generic data. I need extract data with a generic datasource and hope deleted record in datasource also can be "delete" in next delta extraction. I do a test with generic delta. It seem that the delete record can not be updated in ODS. but updated record can be updated in next delta extraction.
How dose BW generic delta deal with the deleted record with generic delta mechanisim? Or how can I use generic delta mechanisim to realize that BW "delete" the deleted record of source system in ODS with delta extraction?
Thanks in advance!
Billy

Delete is not supported in delta mechanism of generic delta extractor. You will need to add a workaround for that.
- Capture the deleted records somewhere (maybe enhance the txn deleting the record so the key is written to a Z table). Take these records to BW and manipulate the recordmode to affect deletion of corresponding record from ODS.
- If your generic delta is based on FM, and if the 'delete' is captured in change document tables, add the logic to check change document tables whether any records are deleted, and if yes, send those to BW with appropriate recordmode to achieve deletion.

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?

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.

Generic DataSource on Function Module - Query

Hi All,
We have a requirement wherin we have to pull data from MARM (Material UOM fields) table. This table has some 1,130,000 records. Since this table doesn't have a Last Changed on or Created on field we are not able to create a Generic Delta on the table itself.
We have come to know that in MM02, we can change the Unit of Measure fields for material. When we update in MM02, both MARA and MARM table gets changed. MARA will be updated with the last changed date.
So we are thinking of creating a Generic DataSource on Function module so that we can perform the delta on Last changed or Created on field of MARA.
I have a doubt about creating the function module. How should we achieve the initial load (Getting all the material and it's UOM to BW) and then Delta loads through the function module?
Does the first load needs to be or should be a full load?
If someone can tell me the steps that should be followed, it would be very helpful
Please let me know your suggesstion.
Regards,
Vivek Das Gupta

Hi
Could u try creating a view based Datasource.
Also u can do a full load in parallel by creating 4-5 Infopackages. After which a Init without data transfer can be done.
Hope this helps.

Generic Datasource

Hi
I have a question regarding generic datasource based on function module... Is it possible to have 2 differents function modules based on the same extract structure (Z1)?
I have one existing datasource (DS_A) based on a function module (FM_1) and extract structure (Z1)
Since I have to change the functionality on the existing function module (creating FM_2) for another datasource (DS_B), I am wondering if the 2 datasources (DS_A and DS_B) could be based on the same extract structure(Z1) created previously for datasource (DS_A)
Thanks!!

hi,
this can be done however this will always create a dependency, like if you have to change Z1 due to one FM1 (like addition of new field) then you need to enhance the code for FM2 as well as e_t_data inFM2 will have the structure same as Z1.
its better to create a copy of the existing strucutre Z1 and use it in Fm2.
regards,
Arvind.

Creat generic datasource"customising undependent of mandant is inadmissibl"

Hello,
I am creating a generic datasource through for a SAP (MCSI) table:
1. After entering the DS name and descriptions and table name, by saving i recieve the error message: "repository change: customising undependent of mandant is inadmissible". With this error, i cannot save the datasource.
2. By clicking on the delta generic: How can i configure the fields (the table is for sales order):
- Field: Which field can i choose: For example there are the fields "data analysis date, data analysis month, .. and ...
- Do i have to choose "Stamp or kalender" radio button and for which reason
- The intervalle (smaller and higher value)
3. The datasource is to transfer data in BI.
Thanks
Ar.

Hi
I hope your first problem is solved ( because of server used QA not DEV)
2. By clicking on the delta generic: How can i configure the fields (the table is for sales order):
- Field: Which field can i choose: For example there are the fields "data analysis date, data analysis month, .. and ...
Ans : Its depends upon which date you business want your delta shuld work, click the F4 help and choose from drop down table.
- Do i have to choose "Stamp or kalender" radio button and for which reason
Again for Transactional data we used TIMESTAMP and for Master data it should be CALENDERDAY.
- The intervalle (smaller and higher value)
For TIMESTAMP +/-30 mins and for CALENDERDAY +/- 2 Days.
3. The datasource is to transfer data in BI.
Yes, Many std. datasources are provided by SAP which also we can modify by doing enhancement.
Also we can write our own DS as per need and requirement.
Thank-You.
Regards,
Vinod.

Delta enable generic datasource

hellow sir ..
im workin on SAP BW 3.5
i'm creating the generic datasource ,, so my confusion is how to make it Delta enabled because The check box for DElta is Greyed...
so wat;s the diference between delta box checked and unchecked..
how to make that grey area checked..
thanks and regards

u r talkin about Generic Delta Tab.. where 3 option s are there,.. - YES
so wat options i shud go for.. so that it enables Delta upload at BW side. - This will not enable delta loading at BI side it will extract delta records from R/3 only, for activation BW delta you have to create a delta infopackage that will extract the delta records from R/3 to BI.
and there are 2 more options in Radio button
- Filed name : Here u specified based on which field ur delta records wil be picked up, like change date field (field name : ERDAT) then specify the name of field, as its a date field so choose the Radio button CAled day. If it had been a time stamp filed u have choosen then Timestamp radio butoon.
1) New status for change Records
2)Additive Delta..
For above read F1 help (that is very clearly explains this)
and what is the DElta check box which is there in Selection and Hide field Tab,, which comes after Saving the First Screen of RS02 ( DATASOURCE : Customer Version Edit ) - This box will become checked when u maitain any delta field in Generic delta tab. It indicates wether the datasource is delta enabled or not
Hope this is clear now.

How to Add delta functionality to generic datasource

Hello all,
My requirement is to make a Generic Transactional Data source Extractor to Delta enabled.
The datasource doesnt contain either of the following delta enabling functionality
-> Date
->time stamp
->Numeric pointer.
Could anyone suggest idea how to add these in Generic Datasource so that it can be delta enabled
regards
Bala

Hi Bala,
Coding should be done checking th trasaction and the tables.
but i can provide outline .
add a field last changed on and write a code saying last changed on is equal to sy-datum.
i am not sure of the scenario where to write this code and after which line.you can take a decision.
check the link below

I am using generic datasource first time init sucessful, next time deltas

Hai ALL,
I am using Generic Datasource first time i run init next time i want to run the delta, delta is sucessful but 0 records. i am taken date field and new status fileds(DSO) for DSO. R/3 side table values chaging but not replicate to BI. Can any suggest how to run the delta for Generic Datasource.
Thanks & Regards,
Suresh

Hi
Have you set delta pointers in your Generic datasource? if yes then what it is ? try to see if its logically related with your changes in records or you need to use any other type of delta pointer.
