ECC Upgrade and XI 3

Hello all,
We're going to start an ECC 6 upgrade project from R/3 4.6C with XI 30 in the system landscape and would like to know if we have first to upgrade the XI system to 70/71.
Since SAP note 1043047 states that PI systems must be at the same version or newer than connected system our concerns are that we could get into troubles without upgrading XI (which is based on 640 while ECC 6 is based on Netweaver 2004s).
Do you have any suggestion ??
Many thanks and best regards,
Michele

Hi,
What I would like to understand is if I have to upgrade first to PI before starting the ECC upgrade project.
Note 1043047 states that "For PI, it is a prerequisite that no other system in the system landscape
has a higher release than the PI system."
This means to me that since ECC 6 is Netweaver 2004s based we have first to reach at least Netweaver 2004s level on the XI side..or am I wrong ?
Thanks and regards,
Michele

ECC upgrade and integration models

Experts,
We are upgrading our R3 system from 4.7 to ECC 6.0. We currently use SCM 5.1. During the upgrade from SCM 4.0 to 5.1, we had to do a re-initial transfer of our PDS integration models and a full curto_create, because the PDS tables had changed so much.
Is there a similar concern with an upgrade of R3 4.7 to ECC 6.0? Should I be doing a re-initial transfer of my integration models after the new ECC 6.0 system is built and released?
Thanks,
Matthew Bruckner

Hi Mathew,
Thanks for input. We are going for upgrade from SCM 4.1 to 7.0.
I never been upgrade of ECC. I think it is always better to do the initial transfer after upgrade.
Any way initial transfer will not create any issues.
Also check T.code SPAU to know the modification in the upgrade system from your old version.
I hope this helps.

Kishore Reddy.

R/3 4.7 to ECC Upgrade and configure clustering

Hello All,
I have a query in which I am looking for a best approach.
Currently I have my R/3 4.7 System on AIX and Oracle. Now I want to Upgrade the system to ECC 6 EHP4 and then configure HA for the ECC System.
Can some body suggest me the best process how to go ahead. I want to install ASCS and Dialog Instance on Node 1 and CI and Database on Node 2. Please explain me how can I seperate my ASCS now as in 4.7 ASCS was a part of CI.
Regards,
Nirmal.K

You can do fresh install the ASCS and DVEBMGS with sapinst (yes even with an ASCS, the first dialog instance is still called central instance). There is also a createscs procedure available, have a look at note [821904 - Separating SCS instances for ABAP and J2EE|https://service.sap.com/sap/support/notes/821904]
But you don't need to do this at all, you can still run the one single central instance on node 1. In your setup splitting the central instance does not provide any additional benefit.
Cheers Michael

Upgrade to ECC 6 and workflow issues

Hello,
We have just upgraded to ECC 6 and have some issues with workflows. Each dialog step in the workflows appear in the respective agents inbox, but once they action, the workflow do no proceed further. The log shows that the step did receive the terminating events, but doesnt proceed from there.
Anyone who had similiar issues, can you please let me know how you went about overcoming this ?
Cheers,
Satish

Hi Satish,
Please check the agent assignment for the dialog step task. Also try by setting the task as a general task (if no particulat agents are desired).
Do let me know in case of further queries.

PKUNRE field not getting populated in 2LIS_13_VDITM after ECC upgrade

Hi,
We are seeing blank values for PKUNRE / 0BILLTOPARTY during extraction from 2LIS_13_VDITM.
We are experiencing this issue after ECC upgrade which went live recently.
We have applied note 580694 to correct missing fields in the billing extractor.
This field is sourced from VBPA/VBRP.
Our functional teams confirmed that VBPA/VBRP are updated properly and there seems to be no timing issue.
However, the record is landing in PSA with blank BILLTOPARTY.
Where could the problem be?
Is there any thing we missed?
Can any one throw some light if you have experienced this kind of an issue after upgrade.
Thanks a ton in advance,
Sandy.

Hi Sandy:
In my system I didn't find the Field PKUNRE on the VBPA / VBRP Tables, so my guess is that you're dealing with a Custom Enhancement, if this is the case the SAP Note 576886 - "Change to user-defined fields not extracted" might help you in solving this issue.
Regards,
Francisco Milán.
***Follow up note:
I double checked and found the Field PKUNRE on the Extract Structure for 2LIS_13_VDITM (using Transaction Code LBWE) so now I know that you're working with a Standard field and not with a custom ehnancement, the SAP Notes below address a similar issue to yours but they are related to Applications 11 and 12, not for App 13. I apologize for the confusion.
Note 621684 - "Fields PKUNRE and PKUNRG are not filled from delivery"
Note 379237 - "BW Content LE-SHP: missing partners in 2LIS_12_VCITM"

SO_OBJECT_SEND does not work after ECC upgrade

Hi Gurus,
I find a problem after ECC upgrade with SO_OBJECT_SEND.
This was used in a zprog and was wroking fine in 4.6 C.
When this prog is executed it sends mails to the users thru SOST/SCOT.
But in ECC , upon execution I did not see the mails in SOST.
The prog passes the User id ( type B) to the receivers table.The mail
is sent to Business workplace but not to SOST/SCOT.
Pls help gurus.

Hi,
Use type U instead of type B.
Type of RECEIVER entry.
The following values are permitted:
'B' : SAP user name
' ' : SAPoffice name
'C' : Shared distribution list
'F' : Fax number
'U' : Internet address
'R ' : Remote SAP name
'X' : X.400 address

SAP HR ECC upgrade

Hi,
Could someone tell me what will be the role of SAP HR abap developer in SAP ECC upgrade.
Specially Payroll programming.
and after the upgrade is done what kind of development support is required.
Many thanks
Swetha

Hi Swetha,
ABAPer needs to check all of the user exits and BADIs implemented before in order to check whether any changes need to be done.
Additionally, if there had been any repairs in the system, these need to be reimplemented after upgrade.
For further reference please check the following links:

ECC Upgrade impact on BDC's

Hi All,
My question is regarding transaction level changes resulting dfrom ECC upgrade.
We are upgrading ECC 4.7 to ECC6.0. There are certain BDC's already working in 4.7 and I need know the transction level changes so as to see impact on BDC pragrams.
I have already tried using SPAU and SPDD for modifications.
Is this kind of information maintained on help or service-marketplace portals? I checked but could not get the information.
Thanks and Regds,
Gaurav

Hi Gautham,
The table u suggested gives details on trasnaction names.
Also the link you have given is about the various issues related to BDC in upgradation process.
My question is different as to find out the changed at transaction level like ...field changes.... mandatory.....sequesce of fields....
is this kind of incormation maintained in any help or service marketplace folders....
I have already tried SPAU and SPDD but don't want to do that for number of transactions.
Regds,

ECC6.0 upgrade and BW steps for mapping the new ECC6.0 source system

Hello gurus
We are upgrading from R3 4.6C to ECC6.0. We use BW 7.0 SP 18. We will create the new ECC6.0 source system in BW, replicate metadata and everything. The question is how do we copy or reassign the existing objects pointing to our current 4.6c dev system (transfer rules, transformations, infopackages, process chains) to point to the new ECC6.0 dev system ? As a note, we also need to keep the current 4.6c source system objects until go-live o ECC6.0.
What is the common practice in such a case ? I am sure we are not unique...
A prompt response would be appreciated.
Thank you all.

So the plan is to copy dev R3 and upgrade that - then Q r3 copied and upgrade that - then upgrade directly prod R3?
If so - then if it were me - I would firstly prove all this in a sandbox environment where BW dev points at an upgraded sandbox R3 ecc
ie same logical system
Then once that is proved I would organise downtime of BW development for a few months whilst the d-q-p ecc happens
Then when they copy dev r43 to ecc r3 i would then just point BW dev at the new ecc box and go from there (ie clear the deltas - change the logical system name to the new ecc box - replicate meta data - transtru all the datasources - run the process chains nothign to worry about)
However if you cant afford the down time - you may have to have an alternative transport route - ie copy dev BW to a another dev bw box and have an alternative path to production for issues
Then once everything is upgraded redo the changes through d-q-p to get the transports back in line (thats what we did)

ECC upgrade

we are performing the ECC upgrade with unicode conversion from 620 system which has db size 7.24TB
1. do any one performed this on similar huge database?if yes give details
2. since db size is high do we need to go for CUUC or upgrade with unicode in two projects
3. how to calculate the downtime apart from the OSS note provided by SAP which is purely theoritical
4. what are the major challenges during export,import

Hi,
I'm going to do Productive Upgrade from 4.6C to ECC 6.0 next week with a 7.4 TB Oracle Database and I have already done 5 tests using a copy from Production database let me give answers your questions:
1. do any one performed this on similar huge database?if yes give details
Yes, R/3 4.6C to ECC 6.0 on HP/UX 11 and Oracle 10.2.0.2.
You will find upgrade info that says the database size is not that critical and this is true as long as you do some fixes before the actual upgrades (of course after real live test upgrades with a PRD copy). The last Upgrade test we did we achieved 7 hours and 31 minutes of downtime not including post upgrade that will be the longest part of the whole process. In our downtime we had to include a lot of support packages and this system has some specific industry solutions that makes thinks harder. The first test run used 117 hours. SAP assesment service is really recomended in this kind landscapes and they helped us to do some cleanup of unused tables or unused data that let us move in the second test to 20 hours and with some other investigation and trials by our own we achieve the final 7:31 time and espect to get a lower time during Production Upgrade because the PRD server and DB server are more powerfull . Downtime depends a lot in Hardware and here the servers are running on servers with 8 1.6 Itanium CPU's and 32Gb of RAM, EVA system for DISKS.
2. since db size is high do we need to go for CUUC or upgrade with unicode in two projects
I will strongly recomend to do it in two projects unless you have a long time that you could use to achieve all this in one step or in case your post upgrade is really short.
3. how to calculate the downtime apart from the OSS note provided by SAP which is purely theoritical
The only way to calculate downtime is to actually doing a test upgrade on a PRD copy. This is also what SAP people will tell you.
4. what are the major challenges during export,import
I can´t answer this as we did not went to Unicode.
Good Luck during your upgrades,

SAP ECC upgrade from EHP6 to EHP7

Is GTS upgrade from NW 7.2 to GTS 7.3 to be mandated as ECC is getting upgraded from ECC 6.0 EHP6 to EHP 7 . Why?

Hi John,
Your statement looks a bit misaligned.. There is no GTS 7.3 version, the SAP Netweaver 7.3* application server on which SLL_LEG GTS component sits.
The underlying Netweaver AS versions between ECC and GTS systems can be different BUT what needs to be the same is the GTS plugin component in ECC and GTS components in GTS system itself, as best practice they should also be on the same support pack level.
If the ECC upgrade from ehp6 to ehp7 requires you to upgrade SLL_PI gts plugin component in ECC, then in this case you should upgrade SLL_LEG component in GTS system to the same version.
I personaly dont think its required, but check Service markeplace for, PAM Product-availability-matrix and other ehp 7 requirements..
Hope this helps,
Branio

SAP ECC Upgrade : Userexit or Related Enhancement been Overwriten

Hi All,
Is that anyone get explanation from SAP why during ECC upgrade most of the enhancement been overwritten and need to re-do.
Thank in advance on your knowledge sharing.
Trevor Wong.

Ok. There might be need to do "adjustmens" in case of upgrade conflict, or just simple confirmations of code enhancements in transactions SPAU + SPAU_ENH.
I think you should find all missing code enhancements there, waiting for adjustment.

ECC upgrade impact on data archival

Friends,
We are working on the data archival SAP version 4.7, parallely ECC upgrades activities are going on. We are working on the archive tools like transactions SARA, SARI etc as part of archiving. Not sure on what changes to the features will be available in the ECC6.0 version and its impact on already archived files. Can somebody give some inputs/direction?
thanks
Nalinikanth.

Hi,
Retrieval of Archived data
1. SAP system support to retrieve data archived from 4.7 system by ECC system. There is no negative impact in retrieving archived data of deferent version in ECC system.
Advice to take back ups of Field catalog, Archive infostructure in case it is Custom or any additional field added to standard structure.
2. Some changes in Archive index is there in ECC system -
In ECC system, if you want to retrieve archived data from FB03 then activate and fill the Archive infostructure, Archive build index will not work.
This method remains same for Material document and other documents
In ECC system SAP recommends to use Archive system instead of building archive index table such as ARIX_BKPF...
Archive Program
1. All the BC sets to upgrade archiving process are been implemented in ECC system, so you can see some changes in the Write program, Delete program.. or for some archiving object you may also see addition of preprocessing program..
For example: MM_EKKO in initial released 4.7 version didn't had preprocessing job, Write job variant had option of company code to archive purchase order. Later BC set was released with upgraded programs with Preprocessing program and in Write variant with selection of Purchase organization instead of Company code.
If you have already implemented latest release of BC sets then in ECC 6.0 will not have any changes otherwise some minor changes you can see.
Please specify which archiving object with program you are concern with.
Store Function
1. In ECC system, SAP has filled up a long standing gap of storing archived data of different company code in separate content repository. This is very much useful when you want to store the archived data of different organization units in different storage repository. This also easy to get rid of data that has completed total retention period from the storage system.
Remain other functionality remains the same. Please let me know if you have any concern about archiving object that you are using.
-Thanks,
Ajay

ECC upgrade impact on BI

Hi Gurus,
We are currently on BI7 but the R/3 version is 4.7. The R/3 is going to be upgraded to ECC6 shortly. I know this is going to have an impact on BI7 since some of the tables & fields are going to be standard, which might have been customized earlier. Can u give suggestions on the impact on BI and what care needs to be taken from a BI perspective during the ECC upgrade. Also, any doc or pointers which talks about such impact on BI. Points will be awarded accordingly. Thanks for the help in advance.
Ud

Hi,
the following are the activities that I can think of Pre- and Post ECC Upgrade on the BI box.
Pre-Upgrade
- ensure that the Delta queue is cleared in RSA7
- check the PI in ECC6.0
- stop all loads from BW
Post-upgrade
- run Init w/o Data Transfer for deltas
- check extraction for full & delta loads
- replicate all data sources in ECC
- activate all rules thru programs
Other than this, is there any other activity a BW consultant has to do. Also, would it make any difference to our upgrade approach if the BW system is BW3.5 or BI7? our system is on BI7 currently.
Additionally, what SAP Notes will have to be applied pre and Post ECC upgrade.
Would the ECC upgrade have any impact on BI Unicode conversion?
Also, I am still worried about the change to Data Sources post-upgrade to ECC as we have a lot of customization. how do i find out which fields in the Data Sources have been standardized in ECC?
Reponses highly appreciated and points duly awarded.
Uday
