Use of Update Table in Delta Extraction ....

Hi all ,
I have a small doubt regarding why there is an update table introduced between statistical table and delta queue in delta extraction process ... why not directly extract data from the statastical table and put it in to the delta queue .....
Kindly help me regarding this ...
Regards ,
Santosh ....

Hi Santosh,
I think it is related to resource, batch and memory, problem. Infact you can use only delta queue if you select direct update, but you use this kind of update only for huge amount of data produced in a short period of time.
The two queue let you divide transaction moment to batch collection moment.
Hope this help.
Ciao.
Riccardo.

Time-stamp Table for delta extraction

Hi SDNers,
What are the BW Time-stamp Tables for delta extraction in Source System(R/3).
Thanks,
Satya

the tables involved are :
ROOSPRMS
ROOSPRMSC
ROOSPRMSF
in the second table (ROOSPRMSC) you'll find the timestamp
M.

Use of update table in Unserialised V3?

HI Pioneers,
Can any one let me know the advantage of Update table in Unserialised V3 update mode?
Thanks,James

hi,
Update table is to store the posted records(V3 update), so the the collective run can pick uprecords from there.
Unserialized V3 update is not used now a days.
Only queued Delta is used

PCA doment missing during the delta extraction

Hi R/3 DBA experts,
We are using Oracle 10g Data base for our ECC6.0 R/3 system.During BW extraction some of the PCA line item records got missed which gets update in data base table GLPCA in R/3 after successful document creation.
We are in the process of analysis to find out the root cause of the issue as we are approaching year end close.
Please let me know how to get the following logs(Information) in R/3
1.Total time taken in Application server for a particular document which was Entered.
2.Total time taken for a document from posting(Document entry) to successful data base server update.
(OR Application server to Data base server update log details OR Document posting to DB write for a document)
Please treat this as a matter of urgency
Regards
Kumar

Hi,
To move the data from Update Tables to Delta Queue, u need to run the V3 Job Control in LBWE. Once if the job is successfully completed then all the data from Update tables are moved to Delta Queue. Check once in the job overview of V3 job control is there any errors.
Hope this helps in solving u r problem

Dave,
1. You can fire SELECTS in an RFC as well, but in your case the data exists in SYSTEM A and the RFC is in System B, so you can't do that. You can fire SELECTS on tables in the same system.
2. Quick example of two table loops - EKKO (HEADER) EKPO (ITEM).
LOOP AT EKKO.
LOOP AT EKPO WHERE EBELN = EKKO-EBELN.
ENDLOOP.
ENDLOOP.
I hope this is clear now.

Code For Delta Extraction Using Function Module

Dear Experts,
I want a sample code for Delta Extraction using Function Module ( If it is customized already working code very helpful ), I have already created Function Module but Full update is happening. If I give delta update again it is retrieving all records. It is very urgent, if you have please send me to the following mail ID.

Dear KJ,
Thank for your response. I saw the code that you sent, you have used some ztables like ZSC_DELTA_IP, ZSC_SAFETY_DELTA, ZSC_SET_EXT_TIME
What are the fields that you have created in these tables , what is use of these tables, can you send the fields that you have used in these tables.
Thanks & Regards,

Generic delta extraction using function module

Hi.
I have a generic datasource , extraction being performed by a function module. The extraction works fine in full update mode. The extract structure has a timestamp field.
I have enabled generic delta using this field(i.e., marked this field in RSO2). I understand that with this setting, I should be able to get delta data when I do a delta request. But it does not seem to happen.
I checked the ROOSPRMSC table for the last(local) timestamp stored there. Now when I do the delta upload I expect to see only those records which are younger than the stored timestamp of last upload.
But I still get the entire set of records.
Questions are :
1. Do I need to explicitly code for fetching the delta in the extractor ?
2. If not, what could be the reason why generic delta is not working ?
Thanks and regards,
Anuradha

Hi GFV,
I read-up all the forum entries on this topic but could not find anything specifically dealing with my problem. I have browsed through the how-to paper on generic delta as well.
I am quite sure that we don't need any special coding in the extrator for generating delta generically. Even the how-to paper does not mention that.
I have used the FM RSAX_BIW_GET_DATA_SIMPLE as a template
for my extractor(as suggested by F1 help in RSO2). This FM does not even have the i_updmode flag in its interface.
Thus this function module always does full extraction and I expect the system to take care of delta using the timestamp field.
Are these assumptions incorrect ?
Regards,
Anuradha

R/3 table to BW via Delta Extraction (Urgent plz)

Hello Experts,
How to load a data from one of the R/3 tables to BW when the table doenst contains either a time stamp, Date field or numeric pointer.
I have PS Table in R/3 (RPSCO) with over 7 hundered thousand records in it. I would like to populate the data to a ODS via delta extraction.
The table doesnt contain either a timestamp, numeric pointer or date. How would I extract a data now to BW via delta. Would it be possible to use Generic extraction.
Thanks and Regards,
Harish

Hi Harish,
If you need ODS to make delta DataMart you can not delete data before every upload.
For spee-up the upload you can follow these solution:
1)Take off from parameters of your ODS Reporting BEx flag. Without this flag the system does not spent time for reporting activation of data.
2)If upload is too slow you can try to make delta in R/3 via a program that compare previous upload and new status of your table, introducing in the tableforthe upload only modified records. It can be very slow, but it is all R/3 time.
Ciao.
Riccardo.

Short dump in delta extract using bgRFC in NW 2004s

Short dump in delta extract after Support Pack install, using bgRFC.
InfoSet Query extractor from Z-table residing on BW system into ODS.
Init and Full loads load successfully, delta loads short dump.
"MESSAGE_TYPE_X"
"SAPLARFC" or "LARFCU25"
"TRFC_SET_QUEUE_RECEIVER_LIST"
Problem began after support pack install, from SP 9 to SP 12.   Switched to Classic RFC in SM59, seemed to correct this extractor but caused problems in other extractors.

Hi Kevin,
check out this note: https://websmp205.sap-ag.de/~form/handler?_APP=01100107900000000342&_EVENT=REDIR&_NNUM=1054970&_NLANG=EN

Delta Extraction Using Function Module ( Customization )

Dear Experts,
I want a sample code for Delta Extraction using Function Module ( If it is customized already working code very helpful ), I have already created Function Module but Full update is happening. If I give delta update again it is retrieving all records. It is very urgent, if you have please send me to the following mail ID.
[email protected]
Best Regards,
SGK.

Hi SGK,
I've done this for a delta based on a timestamp and it's actually pretty easy. The basic steps are:
1) Create an extract structure in SE11. Make sure the structure has a date or timestamp field in it that you can use for delta. You'll need to include the field twice if you also want to extract it to BW/BI since once it's chosen as the delta field then it will be hidden in the interface.
2) Create the extractor function module in SE37. You can use RSAX_BIW_GET_DATA_SIMPLE as a template. Make sure your logic restricts the data it retrieves according to the selections that are passed in I_T_SELECT, including restrictions on the delta field.
3) Create a generic DataSource in RSO2. Click Extraction by FM then fill in your extract structure and function module. Click Generic Delta and pick your delta field and the appropriate radio button (time stamp or calendar day). If your delta field is a timestamp field then be sure to set the upper and lower safety limits to -86400 and 86400 respectively. This might not be necessary on your version of SAPI but on mine there is a bug where it doesn't translate between system time and UTC (GMT) correctly so this was necessary.
You don't need to program any special delta handling logic in your function module as long as you restrict the data you retrieve based on the delta field (I_T_SELECT). This is because the SAPI takes care of catching the init, delta and repeat requests, translating them to the appropriate delta field values, and then passing them to your function module as if it was a full extraction for a specific date or timestamp range.
Hope this helps!

Delta Extraction: Cross Application Table

Hello Gurus,
While enhancing an LO extractor, I understand that we need to create a structure with the fields needed for extraction and then append this to the main extract structure and populate this through the user exit. Now what I am worried about is if the fields happend to be a from a cross application table, how the delta would be taken care of?
As an Example, if I need to add in couple of fields of the delivery tables (LIPS and LIKP) in the Purchasing extractor (2LIS_02_SCL), am I going to get changed fields during the delta extraction?
Thanks...

Is that always true? Please look through the following scenario that Sunmit mentioned in response to Roberto's one of the blogs:
If a scenario demands a cross application enhancement
eg: Enhancing shipment relevant field in a delivery data source/extractor or delivery relevant field in an invoice relevant data source.
Is the delta relevance of these enhanced fields retained by enhancing the datasource at communication structure level? I guess, the delta of these enhanced fields would still be lost, since they are not included in the events that are used to create the delta.
(ie a shipment document (our field) may change without change in delivery document).
Any ideas???

Update table a columns using columns from table b (values of 2 columns of table b need to taken from table c)

Guys,
I need to update table A columns col3, col4, col5 and col6 by table b columns col3, col4, col5 and col6 however table b col5 and col6 values need to come from table c col1.
Means table b col5 and col6 have values in it however i need to replace them with value from table c col1 and need to update table a col5 and col6 accordingly.
table a and table b has col1 and col2 in common.
i am trying something like this.
Update a
a.col3 = b.col3,
a.col4 = b.col4,
a.col5 = (select col1 from table_c c where c.col2=b.col5),
a.col6 = (select col1 from table_c c where c.col2=b.col6)
from table_A a inner join table_b
on a.col1=b.col1 and a.col2=b.col2
can someone help me reframe above update query?
thanks in advance for your help.

Try the below:(If you have multiple values, then you may need to use TOP 1 as commented code in the below script)
create Table tableA(Col1 int,Col2 int,Col3 int,Col4 int,Col5 int,Col6 int)
Insert into tableA values(1,2,3,4,5,6)
create Table tableB(Col1 int,Col2 int,Col3 int,Col4 int,Col5 int,Col6 int)
Insert into tableB values(1,2,30,40,50,60)
create Table tableC(Col1 int,Col2 int,Col3 int,Col4 int,Col5 int,Col6 int)
Insert into tableC values(100,50,30,40,2,2)
--Insert into tableC values(200,50,30,40,2,2)
Insert into tableC values(100,60,30,40,2,2)
Select * From tablea
Update a Set
a.col3 = b.col3,
a.col4 = b.col4,
a.col5 = (select col1 from tablec c where c.col2=b.col5 ),
a.col6 = (select col1 from tablec c where c.col2=b.col6 )
from tableA a inner join tableb b
on a.col1=b.col1 and a.col2=b.col2
--Update a Set
--a.col3 = b.col3,
--a.col4 = b.col4,
--a.col5 = (select Top 1 col1 from tablec c where c.col2=b.col5 Order by c.Col1 asc),
--a.col6 = (select Top 1 col1 from tablec c where c.col2=b.col6 Order by c.Col1 asc)

What Strategies are there for updating a table when you're using a multi-table view to display it.

I'm using a view and am able to create a grid that allows editing of one of the columns. Let's call the table where the column is updated "DepartmentFeeDetail." The view has several joins but up till now the column was editable.
Today I needed to join DepartmentFeeDetail with itself to pick up the debit side of a debit/credit pair. I want to show the gl account number for both
the debit and credit on the same row. I also need to update the value for both debit and credit.
I can no longer edit the column to no surprise. When updating using MSSQLMS I get the following error:
View or function 'MyTestView' is not updatable because the modification affects multiple base tables.
What should my strategy be in lightswitch? The grid is populated by a query that includes my lynq expressions in DepartmentFeeRateQuery_PreprocessQuery. The query may return 1000+ rows. I need to allow the accountant to edit either a single row's column
or enter a value in a field outside the grid and click a button "Apply fee rate to entire page."
All this was working fine until the requirement to show the debit side gl account number and to change the debit side value somehow.
I've tried adding a property to DepartmentFeeDetail but the "Is Computed" property wouldn't allow me to uncheck it. Is there a way to add an editable property for each grid row and initialize it to the
current value of the column returned by the view? I could then update a collection when one of the fields changes. If they change the global value and press "Apply fee rate to entire page"
I can update the collection as well.
Scott Mitchell

What I do is instead of using a View I use a updatable
WCF RIA Service.
This is an example of an updateable method:
public void UpdateQuestionDetailForUser(QuestionDetailForUser objQuestionDetailForUser)
// Get the current user
string strCurrentUserName = System.Web.HttpContext.Current.User.Identity.Name;

RM_NAMEtable BROK_DEALER_MAP doesn't have any duplicate records.
table DTRMIS_REPORT have more than 2 lacks duplicate records.
Now i want to update table DTRMIS_REPORT (DISTRIBUTOR_TYPY COLUMN) With the values of BROK_DEALER_MAP (CATEGORY COLUMN).
For that i have written merge statement like below
merge into dtrmis_report a
using brok_dealer_map b
on (a.brok_dlr_code=b.cons_code)
when matched then
update set a.Distributor_type=b.category
where a.brok_dlr_code=b.cons_code;IT's giving error saying ORA-30926: unable to get a stable set of rows in the source tables.
How to update the table.
Please help.

Please post the output of the below
select cons_code
from brok_dealer_map
group by cons_code
having count(*) > 1;In case of duplicate CONS_CODE, you need to decide with which the target table should get updated
And are you seriously giving a where condition in merge like you posted..?
