Requirement may come up to add new fields to LO cockpit extractor which is up & running in production environment. This means the extractor is delivering daily deltas from SAP R/3 to BW system .

Since this change is to be done in R/3 Production system, there is always a risk that daily deltas of LO cockpit extractor would get disturbed. If the delta mechanism is disturbed (delta queue is broken) then there no another way than doing re-initialization for that extractor. However this reinit is not easy in terms of time & resource. Moreover no organization would be willing to provide that much downtime for live reporting based on that extractor.

As all of us know that initialization of LO Extractor is critical, resource intensive & time consuming task. Prerequisites to perform fill setup tables are – we need to lock the users from transactional updates in R/3 system, Stop all batch jobs that update the base tables of the extractor. Then we need to schedule the setup jobs with suitable date ranges/document number ranges.

Step by Step Procedure:-

1.Carry out changes in LO Cockpit extractor in SAP R/3 Dev system.
As per the requirement add new fields to Extractor.
These new fields might be present in standard supporting structures that you get when you execute “Maintain Data source” for extractor in LBWE. If all required fields are present in supporting structure mentioned above then just add these fields using arrow buttons provided and there is no need to write user exit code to populate these new fields.
However if these fields (or some of the required fields) are not present in supporting structures then you have to go for append structure and user exit code. The coding in user exit is required to populate the newly added fields. You have to write ABAP code in User exit under CMOD & in Include ZXRSAU01.
All above changes will ask you for transport request. Assign appropriate development class/Package and assign all these objects into a transport request.

2.Carry out changes in BW Dev system for objects related to this change.
Carry out all necessary changes in BW Dev system for objects related to this change (Info source, transfer rules, ODS, Info cubes, Queries & workbooks). Assign appropriate development class/Package and assign all these objects into a transport request

3.Test the changes in QA system.
Test the new changes in SAP R/3 and BW QA systems. Make necessary changes (if needed) and include them in follow-up transports.

4.Stop V3 batch jobs for this extractor.
V3 batch jobs for this extractor are scheduled to run periodically (hourly/daily etc) Ask R/3 System Administrator to put on hold/cancel this job schedule.

5.Lock out users, batch jobs on R/3 side & stop Process chain schedule on BW.
In order to avoid the changes in database tables for this extractor and hence possible risk of loss of data, ask R/3 System Administrator to lock out the users. Also batch job schedule need to be put on hold /cancel.
Ask System Administrator to clear pending queues for this extractor (if any) in SMQ1/SMQ2. Also pending /error out v3 updates in SM58 should be processed.
On BW production system the process chain related to delta Info package for this extractor should be stopped or put on hold.

6.Drain the delta queue to Zero for this extractor.
Execute the delta Info package from BW and load the data into ODS & Info cubes. Keep executing delta Info package till you get 0 records with green light for the request on BW side. Also you should get 0 LUW entries in RSA7 for this extractor on R/3 side.

7.Import R/3 transports into R/3 Production system.
In this step we import R/3 transport request related to this extractor. This will include user exit code also. Please ensure that there is no syntax error in include ZXRSAU01 and it is active. Also ensure that objects such as append structure is active after transport.

8.Replicate the data source in BW system.
On BW production system, replicate the extractor (data source).

9.Import BW transport into BW Production system.
In this step we import BW transport related to this change into BW Production system.

10.Run program to activate transfer rules
Execute program RS_TRANSTRU_ACTIVATE_ALL. Enter the Info source and source system name and execute. This will make sure that transfer rules for this Info source are active

11.Execute V3 job Manually in R/3 side
Go to LBWE and click on Job Control for Application area related to this extractor . Execute the job immediately and it should finish with no errors.

12.Execute delta Info package from BW system
Run delta Info package from BW system. Since there is no data update, this extraction request should be green with zero records (successful delta extraction)

13.Restore the schedule on R/3 & BW systems.
Ask System Administrator to resume V3 update job schedule, batch job schedule and unlock the users. On BW side, restore the process chains schedule.

From next day onwards (or as per frequency), you should be able to receive the delta for this extractor with data also populated for new fields.

    Would be a good check list for someone doing a LO enhancement 🙂

    But, the content looks more like a blog. This information would be more useful to learners if you can add some screen shots.

    Step 5 is wrong in part  “Ask System Administrator to clear pending queues for this extractor (if any) in SMQ1/SMQ2. Also pending /error out v3 updates in SM58 should be processed.”

    Instead of clearing logistic queues in SMQ1 you have to move all documents from there to bw queue (RSA7) and then to BW system, so all queues become empty (SMQ1, RSA7). Otherwise you will lose those documents in your next delta load.

    Nice, but it would have been better if you leave gaps between each step. looks to be clumsy at the moment. Content is good. After clearing SMQ1 and RSA7 to BW, then you must lock Users. You need to flush out all deltas till the time to BW(running delta infopackages twice or thrice) and then hold the V3 job.

      Hi Suman,

      Nice to see your comments, thanks for your additional comments/corrections which gives perfect information to the followers or to this blog, so that there will be no future confusions arise.
