Generic delta; When R/3 record deleted.

Hi all
Please tell me What will happen to the BW record when the record in R/3 add-on table is deleted and the data is retrieved by generic delta.
(1)At the beginning.
R/3                         BW
20051124000001   100$   -> 20051124000001   100$
(2)Then, R/3 record deleted.Does the record on BW will be deleted or remain in same?
R/3 record deleted      -> BW record also deleted
                        or
R/3 record deleted      -> 20051124000001   100$
                            remain in same
Now, I cannot access to BW; I couldn't test by myself. So, I wish someone help me.

Hi Ken'ichi,
Refer these posts on RECORDMODE:
Re: ods- 0 Record mode
Re: 0RECORDMODE Question
A generic datasource can be based on:
1. View/Table
2. Function module extractor
3. Infoset query.
You would find many links on the same topic in these forums. Kindly use the search option.

Another DNS record deletion question

I am fairly new to the environment, as i switched my consulting job to an internal job.
The environment was a flat file dns, with one primary DNS server and multiple secondary servers. I move away from the flat file DNS (single master model), to an active directory integrated DNS with multiple DNS zones. So I moved the multiple DNS domains
away from the master zone to their own dedicated DNS zones on the domain controllers within their domain.
The Colleagues already warned me that DNS records tend to mysteriously disappear from time to time, but could not find any proof. I checked the usual suspects (scavenging), but that was disabled. 3 weeks back, I splitted the single DNS zone, in multiple
DNS zones, where the splitted DNS is pointing to their own dedicated domain controllers. I used following procedure to do it:
http://blogs.technet.com/b/askpfeplat/archive/2013/12/02/how-to-split-and-migrate-child-domain-dns-records-to-a-dedicated-dns-zone.aspx
Since the migration we had several encounters of DNS records which were deleted, some were explainable (wrong ILO settings), but some were not. As i could not explain the deletions, i enabled auditing on DNS to see who or what is responsible for deleting
those objects. This morning i was notified that again a records went missing, so I went to inspect the audit logs. To my surprise I saw that my admin account was logged with the record was deleted. Now I did not delete any records, have no scripts running
that modify DNS in anyway, and i seriously doubt that my admin account has been compromised. Is there anyone who could explain why records (A records of members servers) are being deleted, although scavenging is disabled?
I have checked the DNS suffix, and verified that it is not set. In which the client uses the active directory domain to which it is a member.
Answers provided are coming from personal experience, and come with no warranty of success. I as everybody else do make mistakes.

Hi,
Because the Active Directory integrated DNS replication between all the DNS server, one of the DNS server delete the record others will delete the record too, so Mahdi’s suggestion
is better to know what happen when the DNS records deleted.

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.

Generic delta issue - INITIALIZATION - Missing some records

Hello all,
We have create a specific table on our SAP system (4.6C) and a specific datasource.
We have customized a generic delta process (DELTA SPECIFIC FIELD = Last Change Date type DATS).
The table contains 38 records.
When we launch a full loading all the records are extracted (that is to say 38 records).
When we launch a INIT loading (with no selection) only 6 records are extracted.
The generic TYPE for delta field is CALENDAR DAY.
Why the init loading doesn't load all the data contain in the table ?
Some of you have already meet such problem ?
The table structure can be the reason of this problem ?
Points will be done
Edited by: Marc Marquez on Jul 24, 2008 10:56 AM

This test is already done, the problem is on ECC system.
On RSA3 side the behaviour is the same than in BW
FULL loading is ok (all records are extracted)
INIT loading is ok but most of the records are not loaded (6 instead of 38)

Problem in getting Generic Delta records to BW

Hi BW Gurus,
I have got one issues with which I have been struggling a lot for several days . i.e
I am extracting data from R/3 using Generic Extractor (View) from CATSCO and CATSDB. At the time of delta, I tried using Personal No with Time Stamp giving Upper limit as 1800 seconds. I executed Infopackage in BW immediately. But it didn't work out. So plz guide me how I can get Delta Records to BW. Or should I do any necessary factors apart from these in Generic Delta Screen (RSO2).
It is very urgent.
I will be thankful for solving this issue.

Hey I am "Intros" again,,
I am sorry man for giving the wrong T-code mistakenly in my last reply..
To solve the proble...the whole process is same what I told u before..
But... you got to go to T-Code : BD87 , then execute the IDocs manually to bring them in to BW
identify your IDocs which are missing in Monitor screen, then goto BD87 and select those IDocs and click execute... )you can search the IDoc's based on selection conditions)
I hope this will help u...
cheers man..

Here S_NO is P.k.
How can i delete Record when i click on Delete Link.

Manoj,
If something does not work then you should report back on the same thread so that there is continuity to the whole episode. Be as lucid as you can be so that people know whats the scenario. E.g. is not working is not enough. What happens? Does is show error , go blank, goes to another page... all that is important.
Its for posterity, down the line others will also visit the thread (may be).

Problem in extracting Generic Delta Records

Hi BW Experts,
I have an issue. I am using Generic Extractor using View from Tables CATSCO and CATSDB. At the time of Generic Delta, I am using the field PERNR(Personal Number) to use Generic Delta. I am using Time Stamp. For this I have selected Safety Interval Upper Limit 100 seconds.But now I am testing whether we get delta records or not. But I am not getting records to BW. They are changed in R/3. So please guide me whether I should use Calday or Time Stamp . How can I get delta records to BW.For testing , I am executing InfoPackage immediately after changes in R/3 like for two or three minutes. Once I will be sure on getting records to BW, then I can move to Production where we execute process chain at 1:00 a.m
there I can use Calday giving Safety Interval Upper Limit as 1 day. Considering the above factors please guide me .
I will be thankful for solving my issue.

PERNR doesn't contain a date right? so timestamp tells the system PERNR is a date field... That will never work.
What kind of value does PERNR contain, is it an incremental value that adds up at every new entry?
Generic delta needs a field that changes in a way that can be predicted.

Can't delete master record when matching when matching detail record exist

Hi
on the rel. property:
Delete Record Behaviour = cascading
Prevent masterless Operation =yes
Automatic Query = yesCan't delete Record Master & Detail...
On delete getting error msg.
Can't delete master record when matching when matching detail record exist
am i missing something...!
Regards,
Abdetu...

First of all, remember the ripple affect of cascading deletes and updates.
Oracle database allows creating master/detail relationship between tables using foreign keys and allows cascading deletes by defining the FOREIGN KEY constraint with ON DELETE CASCADE clause.
Oracle Forms on the other hand, handle cascade delete thing internally when you set the relation properties.
Now if you have 3 tables with MASTER->DETAIL1->DETAIL2 relationship and you have a form defined with MASTER->DETAIL1 relationship only, it won't let you delete (and save) master or detail record since the third table (DETAIL2) is referencing the rows from DETAIL1 which you are trying to delete.
If DETAIL2 were present on the form, it would have deleted with relation property CASCADING. If you really want that when you delete a master record, all its details should be deleted too, then consider defining FOREIGN KEY constraints with ON DELETE CASCADE and on the form set relation property CASCADING.
And if all master/detail tables are on your form and still it is not allowing you to delete master with cascading, there must be some code preventing it. Check triggers like ON-DELETE, KEY-COMMIT etc what they are doing.

When I stop recording, tracks delete themselves

They'll be red and recording, but then when I hit stop, it disappears. I'm recording multiple tracks.

Are you recording the instruments to the right kind of tracks? This problem is very typical for trying to record an audio input signal to a software instrument track. Then the recorded region will simply vanish, when you stop recording.

Generic Delta Extraction

Hi,
In Generic delta extraction for function module which generic delta we can use
1)Time stamp 2)CAL day 3)Numeric pointer?
What safety upper limit and safety lower milit in time stamp?
When we use safety upper limit and lower limit in Time stamp and numeric pointer?
If possible give 1 scenario for this question
Thanks,

Hi,
Delta with data transfer, you do an init with all the data and marke the requests as delta. The next request will bring the new records and modifications as a normal delta.
Without data transfer, you're only marking the request as delta, the init don't bring any data. Only next deltas will bring new and modified requests.
Normally you'll use init with data transfer and deltas after it.
But imagine you already have an init of a datasource to a Dataprovider, but you'll want to connect that datasource to a new one. Since you already have an init to a first dataprovider, connect it to another new dataprovider, you won't be able to start a new init with data trasnfer to the new dataprovier (without deleting the old one). Therefore, you could bring a full of all the data to the new dataprovider, after that, delete the init flag of the old dataprovider, and create a new init without data. Therefore, the old dataprovider, since already had all the data before, you're only deleting the init flag and create it again, the new dataprovider, you already had sent the data with a full load, so marking the init flag, after that sending deltas will bring new and modified requests to the two dataproviders as what you want.

Generic delta

Hi experts
i have problem in loading generic delta , Generic delta have three parameters
1.Time Stamp
2.Numeric pointer
3.Calender day
and also upperlimit and lower limit
can any one explain me about this parameters and how it works in generic delta
Thanks in in advance

hi,
Yes we have these 3 delta types.
timestamp is used when the requiement of data load is depends on time ie hourly based.
0calday is is used when the requiement of data load is depends on date ie daily based.
Numeric pointer is uesed if u want to load delta based on some fields like sales order,material order.
Lower limit and upper limit used for not to miss the records.

kundan

Regarding generic delta.

does any sap bw gurus know the answer to my doubt.
i have created 3 views from mm tables (EBAN,MSEG,MKPF,GLPCA) AND FROM THESE 3 views i have created 3 generic data sorses in r/3 dev server and transported to r/3 quality server and loaded from r/3 qlty server to ods with full update mode in infopackage.
now i want to load delta records for those geeric data sorses, what is the procedure. i have not selected the delta option while creation of data sorses but loaded into ODS with full update.now i want to get delta records, what is the process?
Suppose i have selected generic delta and given some field to get delta records in r/3 dev server, does it effect in r/3 qualty server or do i need to transport same recquest or new recquest for delta from dev to quality server?
this is very very urgent pls. points assigned.

Hi,
ODS may not let you load deltas if there are Full loads already loaded. So either you have to delete them or make them into Full repair using FM RSSM_SET_REPAIR_FULL_FLAG.
This you can decide after talking to users, if they are ok with the data unavailability during the reload, you can delete these data.
Then perform the changes (delta DS) in the DEV and transport it to QUAL.
Then the usual procedure, replicate in BW, perform init load and start deltas.
Hope this helps.
Thanks,

Doubt Reg Generic Delta "Safety Interval" Setting

Hi Experts,
I have a doubt regarding Setting "Safety Interval Upper Limit" and Lower limit in RSO2 for generic delta.
What does this setting imply?
If I do setting for calender day say both 1 then wht will be difference between delta before setting amd after setting?
Plz explain in terms other tham help provided...
Points will be awarded to say thanks..
Thanks in advance,
Sorabh

Hi Sorabh,
Here some SAP informations:
Safety Interval Upper Limit of Delta Selection
This field is used by DataSources that determine their delta generically using a repetitively-increasing field in the extract structure. The field contains the discrepancy between the current maximum when the delta or delta init extraction took place and the data that has actually been read. Leaving the value blank increases the risk that the system could not extract records arising during extraction. Example: A time stamp is used to determine the delta. The time stamp that was last read is 12:00:00. The next delta extraction begins at 12:30:00. In this case, the selection interval is 12:00:00 to 12:30:00. At the end of extraction, the pointer is set to 12:30:00. A record - for example, a document- is created at 12:25 but not saved until 12:35. It is not contained in the extracted data but, because of its time stamp, is not extracted the next time either.
For this reason, the safety margin between read and transferred data must always be larger than the maximum length of time that it takes to create a record for this DataSource (with a time stamp delta), or it must display an interval that is sufficiently large (for determining delta using a serial number).
Safety Interval Lower Limit
This field contains the value taken from the highest value of the previous delta extraction to determine the lowest value of the time stamp for the next delta extraction. For example: A time stamp is used to determine a delta. The extracted data is master data: The system only transfers after-images that overwrite the status in the BW. Therefore, a record can be extracted into the BW for such data without any problems.
Taking this into account, the current time stamp can always be used as the upper limit when extracting: The lower limit of the next extraction is not seamlessly joined to the upper limit of the last extraction. Instead, its value is the same as this upper limit minus a safety margin. This safety margin needs to be big enough to contain all values in the extraction which already had a time stamp when the last extraction was carried out but which were not read. Not surprisingly, records can be transferred twice. However, for the reasons above, this is unavoidable.
Extracted Data Delta Type
The system uses the delta type to determine how extracted data is to be interpreted in BW, and into which data targets it can be posted.
A distinction is made between the following:
1. Additive delta
The key figures for extracted data are added up in BW. DataSources with this delta type can supply data to ODS objects and InfoCubes.
2. New status for changed records
Each record to be loaded delivers the new status for the key figures and characteristics. DataSources with this delta type can write to ODS objects or master data tables.

Urgent: Problems in Generic Deltas by Function Module

Hi BW Experts,
My requirement is to extract text from CRM to BW using Zfunction module, copy of RSAX_BIW_GET_SIMPLE_DATA
which works fine for full loads but the problem arises only when i go for generic deltas. My code in FM for Deltas is:
LOOP AT s_s_if-t_select INTO l_s_select.
CASE l_s_select-fieldnm.
WHEN 'ZDATE'.
s_date_from = l_s_select-low.
s_date_to = l_s_select-high.
WHEN OTHERS.
ENDCASE.
ENDLOOP.
IF s_date_from IS INITIAL.
s_date_from = '20060401'.
ENDIF.
IF s_date_to IS INITIAL.
s_date_to = '99991231'.
ENDIF.
OPEN CURSOR WITH HOLD S_CURSOR FOR
SELECT * FROM STXH
WHERE TDOBJECT = 'CRM_ORDERH'
AND TDID = 'A002'
AND TDSPRAS = sy-langu
and TDLDATE between s_date_from and s_date_to
or tdfdate between s_date_from and s_date_to.
ENDIF.
FETCH NEXT CURSOR S_CURSOR
APPENDING CORRESPONDING FIELDS
OF TABLE wa_stxh
PACKAGE SIZE S_S_IF-MAXSIZE.
TDFDATE is creation date and TDLDATE is changed on
My extract structure contains Zdate(TDLDATE), Ztext1,2,3, Key field and langu in RSO2 I have selected calday in generic delta and Zdate as field Nm and upper limit as 1 and lower limit as space in settings and new status for changed records button.
Did I missed something because when i check in RSA7 i didnot see any changed records under totals column and i tried to load without it into BW than i didnot received single record evenafter changes.Would anyone suggest me the good solution for it I appreciate it in advance. I have seen lot of posts in SDN but I didnot find this type of secenario anywhere.
Thanks in advance
Regards
Kishore

Kishore,
go through the thread... which i provided for Generic DS using function for CRM Texts.
Re: Urgent: Extraction through function module
Any questions please let me know. If you have any questions update the thread with your mail id.
Replace the code with ...
LOOP AT S_S_IF-T_SELECT INTO L_S_SELECT WHERE FIELDNM = 'ZDATE'.
MOVE-CORRESPONDING L_S_SELECT TO L_R_TDLDATE.
APPEND L_R_TDLDATE.
ENDLOOP.
OPEN CURSOR WITH HOLD S_CURSOR FOR
SELECT * FROM STXH
WHERE TDOBJECT = <Text Object>
AND TDID = <Text ID >
AND TDSPRAS = sy-langu
AND (TDLDATE IN L_R_TDLDATE
or TDFDATE IN L_R_TDLDATE).
ENDIF. "First data package ?
Fetch records into interface table.
named E_T_'Name of extract structure'.
FETCH NEXT CURSOR S_CURSOR
APPENDING CORRESPONDING FIELDS
OF TABLE wa_stxh
PACKAGE SIZE S_S_IF-MAXSIZE.
L_R_TDLDATE will be calculted by the system. Internally, system will save the Last Delta date(you need to enable this field for Generic delta).
all the best.

Need help for record deletion from custom table

Hi friends
I have to write a custom program which will be generic to delete any table record with date field.
This program needs to be generic (should be able to delete records from any custom table) in nature with selection screen parameters as:
Table Name and Number of Days prior to which records are deleted, both mandatory.
Program Flow:
1.     From number of days calculate date before which records are deleted, ( current date u2013 no. of days = past date).
2.     Custom table have date field, delete records prior to that date.
3.     Program may be scheduled for background job, put default values for both fields. No. of days should not be less than 60.
4.     Classical Report output with number of records deleted.
My query is how will I know the name of the Date field so that I can write a DELETE query.
If I use 'DDIF_FIELDINFO_GET' it gives me all field names but how to filter out?
with regards
samikhya

Hi
I have added field on the selection screen as p_fieldname and got the F4 help for it , so that the user will get the field name run time as per the table name.
Now I am facing problem while writing the DELETE query.
I wrote like
DELETE (fp_tab)
where (fp_fieldname) LE date
It is not working. I also tried with taking a string to concatenate fp_fieldname, LE and date to l_string
when I write like this:
DELETE (fp_tab)
where (l_string) , sy-subrc is getting 4 and no records are getting deleted.
I do not understand where the dynamic Delete is failing??
