SAP Business Warehouse: Step by stepprocess to clear extract & delta queues duringpatch/upgrade in ECC system

Posted by Puja Yerunkar Nov 25, 2013I am writing this blog to give you the steps to be performed during ECC system patch/upgrade:

Process: In SAP ECC system any transaction posted into data base tables it will post entries in BW relatedextract Queues (LBWQ or SMQ1) related to LO cockpit. These queues need to be cleared before applying anyPatches or upgrade into ECC to minimize data loss if any changes in extract structures.This document show step by step method to clear LO queues before applying the patches/upgrade into SAPECC system.

Note: Below given JOBS/INFOPACKAGES names may vary in your scenario.Procedure for V3 jobs of R/3 and Info packages scheduling before taking the down time:1) Schedule the below mentioned V3 jobs 4- 5 hrs before taking the down time continuously on hourly basisin SAP ECC system.Ex. Jobs,

a. LIS-BW-VB_APPLICATION_02_500 b. LIS-BW-VB_APPLICATION_03_500 c. LIS-BW-VB_APPLICATION_11_500 d. LIS-BW-VB_APPLICATION_12_500 e. LIS-BW-VB-APPLICATION_17_500 f. PSD:DLY2330:LIS-BW-VB_APPLICATIO

2) 2) Schedule the below mentioned info packages 4-5 hrs before taking the downtime in SAP BW/BIsystem.BW client XXX.Ex. Info Package Name:

a. MM_2LIS_03_BF_RegularDelta_1b. MM_2LIS_03_UM_Regulardelta_1c. 2LIS_13_VDKON(DELTA)1d. Billing Document Item Data:2LIS_13_VDITM:Delta1e. 2LIS_12_VCHDR(Delta)1f. 2LIS_12_VCITM(delta)1g. Sales Document Header Data:2LIS_11_VAHDR:h. Order Item Delta update: 2LIS_11_VAITM:i. Order Alloctn Item Delta1 updat :2LIS_11_V_ITM :

3) 3) Ensure that there should be minimum data in Queues (i.e. in SMQ1or LBWQ and RSA7) if data is veryhigh then again schedule the V3 Jobs in R/3 & info packages.

Steps 1 to 3 are to be followed before taking down time to minimize data extraction time during downtime for patch application.

4) 4) After taking the Down time SAP Basis team will inform BW team for clearing the Queues in ECCsystem.

5) 5) Follow the following procedure to clear Extract Queues (SMQ1 or LBWQ) and delta Queues (RSA7)(i.e. Before Application of Patches or upgrade)a) Request SAP basis team to Lock all users in SAP ECC system (except persons who clearing the queues)and take down time of 45 minutes or depending upon your data volume or plan.

b) Make sure that all jobs are terminated nothing should be in Active status except V3 & BW extraction Jobs inSAP ECC system.

c) Take screen shot of Tr. Code: SMQ1 or LBWQ before scheduling the V3 Jobs

d) Screen shot of Tr Code: RSA7 before extracting the data to BW



e) Screen shot of LBWE extraction structure



6) 6) Copy following V3 Jobs in SAP ECC system - and schedule it immediately in down time for every fiveminutes to move data from Extract Queues (SMQ1 or LBWQ) to Delta queues(RSA7).Ex.V3 Jobs,

LIS-BW-VB_APPLICATION_02_500 LIS-BW-VB_APPLICATION_03_500 LIS-BW-VB_APPLICATION_11_500 LIS-BW-VB_APPLICATION_12_500 LIS-BW-VB-APPLICATION_17_500 PSD:DLY2330:LIS-BW-VB_APPLICATIO

6.1 To Delete unwanted Queues in SAP ECC system.These queues Ex. MCEX04, MCEX17 & MCEX17_1 are not being used in your project hence you need todelete these queues in ECC system.Deleting procedure: Enter the Tr. Code SMQ1 and select the MCEX04 then press the delete button, it will takefew minutes to delete the entries.Follow the same procedure to delete other not required queues in your project.

7) Then schedule the info packages in SAP BW (XXX client) until the RSA7 entries become 0. BW client XXX. Ex. Info Package Name:

MM_2LIS_03_BF_RegularDelta_1 MM_2LIS_03_UM_Regulardelta_1 2LIS_13_VDKON(DELTA)1 Billing Document Item Data:2LIS_13_VDITM:Delta1 2LIS_12_VCHDR(Delta)1 2LIS_12_VCITM(delta)1 Sales Document Header Data:2LIS_11_VAHDR: Order Item Delta update: 2LIS_11_VAITM: Order Alloctn Item Delta1 updat :2LIS_11_V_ITM :

8) If still Extraction queue (SMQ1 or LBWQ) has entries, repeat the step 6 to 7 until both the extract Queuesand delta Queues read ZERO records.

9) After zero records repeat the step 6 to 7 for double confirmation to avoid any possible data entries.

10) Screen shot of Tr Code: SMQ1 after become ZERO.



11) Screen shot of Tr. Code: RSA7 after become ZERO.



12) After ensuring that SMQ1 or LBWQ and RSA7 read ZERO entries, release the system for Basis for anyupgrade or patch application.

13) After patch or upgrade is over SAP Basis team will inform SAP BW team to check the extract Queuesand delta Queues are getting populated or not.

14) Request SAP Basis team Restore the all V3 jobs in ECC system to Original position and unlock all theusers or system/communication users.

15) Check the Tr. Code: SMQ1 and RSA7 whether the entries are getting posted or not after restoring theV3 jobs in ECC system. See the screen shot



RSA7



16) Check the Tr, code LBWE whether all the Extract structure or active or not see the screen shot afterpatch application.



17) Schedule the any of the info package in SAP BW ( from above list) See the screen shot

This ends the Queues clearing activity.

Useful info.Puja.Thanks for sharing this.

Definitely come handy for BASIS team as well.We can simply share this document with them and they will alsobe aware of activities need to be carried out during any sort of upgradations.

Regards,AL

Veeramalla VNov 27, 2013 7:47 AMvaluable inputs for upgrade, we can keep these in cut over checklist.

Puja Yerunkar in response to SK S on page 12Nov 26, 2013 6:27 AMHi,1) For scheduling V3 Jobs: Enter T code LBWE --> select particular Application Area say Purchasing--> Drill down to extract structures--> check all the required data sources are active or not--> select "Job Control"--> new window will open as "Job Maintenance for collective update"-->Enter Job parameters like-->Start date, time,Period values etc..->and in control parameters-->click on schedule job tab to schedule the JOB.it will create background job as per above given parameters likeLIS-BW-VB_APPLICATION_02_500.this completes V3 job schedule.2. All the Suspended Process chains will start immediatly after server goes up but load on the source systemwill increase drastically, it will impact on transactions. hence best practise will be stop all the process chains atthe time of upgrade or patch application and reschedule all the jobs as per suitable timings once the serversgoes up.

Manna DasNov 26, 2013 5:22 AMthanks for the detailed explanation on how to clear the delta queues.

Nov 26, 2013 12:41 AMThanks,1. Can you please detail how to run and clear V3 jobs in ECC2. Can you please detail suspend process chains which are scheduled for nightly load or delete/releasePCs...do we need to change timings in their variants ?3. post upgrade, how to reschedule the process chains
