Regarding LIS Extract Structure and Delta Queues

Hi All,
We are extracting data using 2LIS_01_S001. But we are unable to pull Delta loads. When we verified we found that the structure (Fields)of the Delta queues are not in same order as S001 table. So, we modified the structures of delta queues using the access key. Now the order of fields in S001, S001BIW1 and S001BIW1 are all same. Till now I was unable to load the deltas for the data source. Now my doubt is should I have to do the LIS setups again (Statistical Information Setup)or can I do a Full Load and do deltas directly???

Hi,
You have to setup the tables once again.If your requirement is to load the customer data donot depend on LIS because there are lot of problems with this LIS.SAP is not recommending this LIS.Simply load customer attribute data and load transaction LOS also.
This is a better option.
Hope this helps.
Assign points if useful.

Enhance extract structure and deltas

Hi All,
We are modifying our first extract structure (well looks like it). We need to determine a key figure based on lookups and values of other fields.
Should we enhance the extract structure to pass these fields and then determine the key figure in the update rules to the cube or should we determine the key figure on the SAP side and pass to BW? If we determine the key figure on the SAP side does it update the delta queue with this value?
So does the delta queue get updated with this key figure? Meaning, does the code in the extract structure get executed during the update to the delta queue or do we have to pass the "lookup" values (basically characteristics) to BW and then determine the value of the key figure?
Thanks so much!

Hi,
This can be done at either of the places. This is all dependant on where can we afford to.. in terms of system uitlization. That is, if the look up table is too big in SAP and we have a small volume in BW then its better in BW and the viceversa of it.
Either in BW or in SAP, the logic is going to take some time to execute and hence the decision relies mostly on this.
Yes the delta queue would be filled with this logic, if we add the key figure in SAP.
Hope I am clear.

Clearing Extraction and Delta Queues

Hi Guys,
I have a quite a problem. I am needed to clear Extraction and Delta Queues, but because there are users in the system they just keep repopulating once i have cleared them. Now these queues have to be cleared for a SAP Upgrade and the Upgrade wont continue until both are clear.
I was wondering is there a way to clear both queues with users in the system making changes?
A quick response would be greatly appreciated!
Thanks in Advance,
Nick

Hi,
There is on program"RMBWV*"
where * is equal to application.
It is used to move the entries from extraction queue to delta queue.
After everthing is there in the rsa7,then you need
to run the info package untill the entries become "zero" in rsa7.
May be try to run more than once.
Note:-You need to take business down time ie lock all the user
so that during that time no one update any data.
Hope this i shelpful.
Thanks,

Diff between update queue and delta queue

hi all
can anyone tell me wats is the diff between update queue and delta queue? wats is delta queue and update queue?
wats are the possible system generated errors and custom generated errors?
Thanks,
Shreya

Hi Shreya,
Update queue(LBWQ) comes into the picture when you choose Queued Delta for the Datasource. the data first comes to the Update queue and than goes to the Delta queue, however if you have choosen Direct Delta than the posted record will directly go to the Delta queue(RSA7).
Here is the URLS for Roberto's weblog to understand the whole LO-Extraction process.

Difference between Direct delta and delta Queue

Hi,
1.ease explain me the concept of Direct delta and delta queue in LO extraction
2.Why set up tables are used and initially why the data is deleted for th setup tables.
3.Please explain me the LO extraction with an example.
Thanks
Alok

Dear Aloka,
1.
Direct delta:
transactional data or application posting will be directly available in the delta queue table with out any intermediate tables. then that data will be extracted from r/3 to bw.
Each document posting is directly transferred into the BW delta queue
each document posting with delta extraction leads to exactly one LUW in the respective BW delta queues
Transaction postings lead to:
1. Records in transaction tables and in update tables
2. A periodically scheduled job transfers these postings into the BW delta queue
3. This BW Delta queue is read when a delta load is executed.
Pros:
Extraction is independent of V2 update
Less monitoring overhead of update data or extraction queue
Cons:
Not suitable for environments with high number of document changes
Setup and delta initialization have to be executed successfully before document postings are resumed
V1 is more heavily burdened
Queued delta:
first the data posting will available in the extraction queue table. then there periodic job run take that data to queued delta table.
Extraction data is collected for the affected application in an extraction queue
Collective run as usual for transferring data into the BW delta queue
Transaction postings lead to:
1. Records in transaction tables and in extraction queue
2. A periodically scheduled job transfers these postings into the BW delta queue
3. This BW Delta queue is read when a delta load is executed.
Pros:
Extraction is independent of V2 update
Suitable for environments with high number of document changes
Writing to extraction queue is within V1-update: this ensures correct serialization
Downtime is reduced to running the setup
Cons:
V1 is more heavily burdened compared to V3
Administrative overhead of extraction queue
2.
Setup tables are used for Full/Initial Update.
Instead of pulling data from DB Tables directly, we r filling Setup tables and extracting data from the Setup tables, which dont have performance impact on DB Tables.
Setup tables are application specific.
It is cautious method to delete Setup tables before filling it for a specific DataSource.

How to find all the Master data extract structures and Extractors

I intend to create Master data dimensions closely similar to SAP BI in a 3rd party system. I would like to use SAP's standard extractors for populating the master data structures in SAP BI and then use a proprietary technology to create similar structures in a 3rd party database.
Question: How to get a complete list of all Master data extract structures and corresponding extractors?
Example: In ECC if I do SE80 and give 'Package' and 'MDX' and then press the 'display' spectacles, I get a list of structures and views under "dictionary objects" covering Material, Customer, Vendor, Plant Texts and attributes.
How do I get the remainder of the Master data extract structures viz. Purchase Info Records, Address, Org Unit etc?
Regards
Sasanka

Hi,
try the table ROOSOURCE and search the data source with string in astrick attr for master data and for text with text
This will give you the list of all the master data source in the system and it contains a column which tells about the extract structure and function module used by each.
Thanks

Difference Between Update Queue and Delta Queue

Hi Experts ,
Could u brief out the difference between Extraction Queue , Update Queue and Delta Queue ?

Hi
a) Serialized V3 Update(If you set this as your delta mode then data will populated into extraction queue tables)
This is the conventional update method in which the document data is collected in the sequence of attachment and transferred to BW by batch job.The sequence of the transfer does not always match the sequence in which the data was created.
b) Queued Delta(If you set this as your delta mode then data will be populated into update queue tables)
In this mode, extraction data is collected from document postings in an extraction queue from which the data is transferred into the BW delta queue using a periodic collective run. The transfer sequence is the same as the sequence in which the data was created
Delta queue is a table which collects data from extraction queue/update queue tables based on the frequency you have set(daily/hourly etc)..from these tables we will get delta records to bw with infopackage delta run..
Hope it helps
Thanks
Teja

Extract Structure and its program

Hi Experts,
Is it possible to know what program/function module is used by datasource extract structure to get the data?
In my case i need to know this information regarding the extract structure HRMS_BIW_IO_OCCUPANCY (0EMPLOYEE_ATTR).
Thanks in advance.

Since a lot of time ago (the last time I met him) he lent 10 euros to me, I was just remembering that I'm still in debt to him !

Difference between Extraction Structure and Datasource

Hi Gurus,
I have a very basic question here.Can anybody explain to me in detail the difference between an extraction structure and Datasource.
Thanks in advance

Hi:
I am pasting a summarized def. from sap notes.
http://help.sap.com/saphelp_bw30b/helpdata/en/ad/6b023b6069d22ee10000000a11402f/frameset.htm
Data Source:
Data that logically belongs together is stored in the source system in the form of DataSources. A DataSource contains a number of fields in a flat structure used to transfer data into BW (Extract Structure).
Extract Structure:
In the extract structure, data from a DataSource is staged in the source system. The extract structure contains the amount of fields that are offered by an extractor in the source system for the data loading process.
You can edit and enhance DataSource extract structures in the source system. To do this, in the BW Administrator Workbench choose Goto à Modeling à Source Systems à Your Source System à Context Menu (right mouse click) à Customizing Extractors à Subsequent Processing of DataSources.
While, you are on the topic, you have one more structure.
Transfer Structure:
The transfer structure is the structure in which the data is transported from the source system into the SAP Business Information Warehouse.
It provides a selection of the extract structure fields for the source system.
It may be a good idea to look into a sample Business Content extractor to get a better understanding of how they are related.

Extract structure and table

Hi Experts,
How to know the fields of a extract structure are populated data from which tables?
Thanks,
Bill

Hi,
Datasource / tables in the source system
Go to RSA2 (DS Repository) in your source system and display your source system.
If Extraction Method is 'V' - you are lucky and you see table name where data is taken from.
If it is F* - function module is used, and you have to go thru its code to see all the tables it uses and logic how data is
processed.
Ext. Meth   Short text
V                 Transparent Table or DB View
D                  Fixed Domain Value
F1                Function Module (Complete Interface)
F2                Function Module (Simple Interface)
Q                 Extraction Using ABAP Query
A                 DataSource Append
or
Table ROOSOURCE in ERP.
Relevant fields EXMETHOD, EXTRACTOR.
IF EXMETHOD = V, EXTRACTOR is view or tablename
IF EXMETHOD = D, EXTRACTOR is name of domain
IF EXMETHOD = F1, F2 EXTRACTOR is name of FM
IF EXMETHOD = Q EXTRACTOR is name of Info set
OR
Since you have the extract structure and the extractor, you must have some transaction like the Extractor Checker RSA3. If so
then execute ST05, switch on the trace and execute the extractor checker. Once the extractor checker presents the results
switch off trace. The clcik on Display trace and you will see all the tables that were hit by the extractor checker to
retrieve data and present it to you.

How to Transport Extract Structure and datasource

Hi all!
I had recently made enhancements to 0CO_PC_PCP_01 datasource.When I transported the datasource and the Extract structure, I noticed that only the append structure has been transported. The datasource has not been transported.
Could some one tell me how to collect the datasource and the Appended extract structure and transport them.
Thanks,
S.P

Hi Jaya,
I had already tried this already. When I selected the dtasource and selected the transport button. I got the message, action successfully executed. When I checked in SE09, I see no transport. Unless it asks me for a transport request, I will not see it in SE09, right.

Enhance extract structure and RSA7 (not LIS)

I have an extractor (not an LIS one) that I have enhanced to have an additional field. This extractor is delta enabled and uses the RSA7 delta queue. I am being told that to implement in production I have to
1) run a delta load to clear the delta queue
2) stop all users in R/3 from psoting
3) transport the change
It is the step 2) I question - is it really necessary to stop users posting. the argument is that the queue structure will change and may invalidate some delta records. But if I'm just adding a field to the structure I do not think this will mess up the delta's inthe delta queue?
Anyone know with confidence?

Hi,
Yes you have to clear you delta queue; don't forget that you have to run a delta twice since the repeat of a delta needs to be cleared as well.
At the end you have 0 (LUWs) in RSA7
You can also check the number of LUWs pending in SMQ1.
You need to empty your delta queue before transporting your changes.
Simply because if you have data in the queue and you import your changes not only the structure will change, all related programs as well (internal SAP programs not your extractor itself). When you'll request the next delta, the system may not find your new field for the data or just by checking timestamps and versions of the objects will simple refuse to extract it! And if you can't extract it then you'll have to reinit.
Since you need to have an empty queue, how could you ensure that it remains empty other than preventing users to post transactions?
If your point is to NOT disrupt operations and your are able to reload the possible missed transactions, then empty your queue, delete the init, import your changes and then re init your delta; which I think will suits you better.
In theory you are right, you don't need downtime for postings and we have tested that with no issue for NON LIS sources (the data is stored at posting time); still I don't recommend it.
In any case, if you are well prepared, the disruption is only 5 or 10 minutes max in the source system during which you stop background processing with BTCTRANS1 (if I remember correctly) and you lock/kick user out (during the night for example).
We have done that lots of times and are running R/3 with different time zones.... so we always take the opportunity when R/3 guys need a downtime for any parameter changes or DB stuff...
hope this helps
Olivier.

How to delete the data in update queue and delta queue for Queued delta?

Dear BWers,
How do i delete the delta queue and update queue data before i fill the setup tables for a extraction based on Queued delta. Please help.
Thanks

Hi Raj,
I think you need some ground work for the LO extraction same as others here. Please read the 3 blogs expliciltly created for LIS by Robert Negro.

As well, the OSS 380078 would clear your doubts reagrding the the BW QUEUE mainatinance.
Please let me know if these material has been suffecient enough.

Lis extract structures

Dear consultants,
i have problem with lis structures (like 2LIS_17_IOCAUSE)
before transfering into my bi system i need to fill these structures with transaction
Managing Transfer Information Structures - Initialization -Filling in the Setup Table-Application-Specific Setup of Statistical Data.
is there any way to fill these table automatically? or i should fill these tables everytime i load data to my bi system?
thanks

Dear Ramesh,
my lis structure is 2LIS_17_IONOTIF. therefore it has delta capability. However, i do not know wehere to set it and what else have to do.
Do i need to;
1) Activate 2LIS_17_IONOTIF in Logistics Extraction Structures Customizing Cockpit.
2) Set Plant Maintenance: BW in Logistics Extraction Structures Customizing Cockpit as;
Update:Job control and Update Mode:Queued Delta?
3) What else have to be done?
Thanks in advance..

LIS (Extract Structure to Datasource) Documentation

Hi
Does anyone have any good documents that explain the relationship with the LIS and the extract structures etc.
I understand that they are predefined Extract structure from (LIS) and if you add more fields then you must do ABAP too to make sure these are filled.
As per my post yesterday I originally thought that as the fields were in the main table in SAP anyway then it would just be a case of just adding them to the extract strucuture in SBIW.
This now seems worng
Any documentation is very welcomed.
