Unicode conversion and patching simultaneously

Hi All -
We are planning to convert our core ECC 6.0 system to Unicode this year as well as patch it to the latest support pack stack. In order to minimize regression testing time, we are going to do them both at the same time so the functional teams only have to test once.
The question is which order to perform the tasks in: convert to Unicode first, THEN patch, or patch, THEN convert? I'm not sure the order matters, but I can't find any definite documentation either way. Has anyone had any experience with this that they would be willing to share?
Thanks for your help!
Abby

Hi Abby,
this depends on what you mean by "patches" ?
Do you want to combine the Unicode conversion with applying support packages only ?
Or do you want to implement EhPs as well ?
If you go for EhPs, I would recommend to do this before the Unicode conversion. This is also the "normal" approach when combining an upgrade with a Unicode conversion.
In case of support packages only, both ways are possible (Unicode first and then SPs or vice versa) ...
By the way I assume you do not have an MDMP system - this would add some additional constraints ...

What's the best solution Unicode Conversion and Upgrade on AS 400

Hi Guys,
We have a R/3 4.6C system on AS400 server. Within this year, we' like to change hardware and DB vendor (Oracle), in the meantime we also need to perform the UC and upgrade to ECC6.0.
What 's the best scenario? we have below suggestions.
1
Step1 - Heterogeneous migration and perform UC to new server and DB in one migration (export / import)
Step2 - Upgrade ECC6.0 Unicode
(not sure about this solution, is Unicode conversion to 4.6C without upgrade possible?????)
2
Step1 - Heterogeneous migration to new server and DB
Step2 - UC&UP
3
Step 1 - Heterogeneous migration to new server and DB
Step 2 - Upgrade to ECC non-unicode
Step3 - Unicode conversion to ECC unicode
????? which is better? 2 big question
- is Unicode conversion to 4.6C without upgrade possible?????)
- what's the difference between UC&UP and upgrade first and perform UC later, which is better?
Thanks very much
Lin

Hi Lin,
I assume you have an EBCDIC database at the moment.
Point 1 is not possible, since 4.6C is not supported with Unicode.
The difference between CU&UC and a separate Upgrade and a later Unicode conversion is that CU&UC is done in one downtime. However you need to evaluate whether this is possible with your downtime requirements.
My recommendation would be to do the Migration and after that the CU&UC approach (if this is possible in a feasible downtime window - this is highly dependent on your system size / downtime requs / hardware capabilities).

Java Add-in or unicode conversion first?

Hi all.
I have just performed a BW 3.5 (NW 6.40) to BI 7.0 (NW 7.0) NON-unicode upgrade. The next two things we want to do are unicode conversion and java add-in installation.
I am wondering which of these actions should come first; Java add-in or unicode conversion?
Any thought on this?
Regards,
Thomas

It´s pretty straighforward using the sapinst.
Make sure you patch up the AddIn to the same patchlevel your ABAP is running on (means,if you BIND support package 13 to the upgrade, upgrade the Java engine to SP13 as well after installation).
Personal opinion:
If we have the choice we don´t use the Java Addin but install the Java part on a separate system. The Addin adds more complexity and dependency to the system. On top of that it makes memory configuration and predictability of sizing very difficult.
This is - however - my personal opinion, this may or may not be true for your environment.

Combined upgrade & Unicode conversion.

Hi
I need some suggestions for my concerns: I would appreciate, if you reply ASAP for below situations and actions.
Current system: HP unix DB: Oracle10.2.0.2
SAP 6.20 with SP 61, single code page
strategy: resource minimized.
Upgrading from 4.7 was 6.20 to ECC6.0 with CU & unicode conversion.
we ran UCCHECK and provide the list to ABAP, but they are not modifying now.
Mean while we started the preconversion steps for unicode conversion and completed. SPUMG.
Upgrade prepare is completed and currently in begining of down-time.
so far ABAP programs are not unicode complaint!!!
we don't know, when would they modify??
If we complete the upgrade and post upg steps for ecc 6.0 and
pre coversion steps for unicode.
is it a problem, if the ABAP programs are not modified yet, can it be done after conversion and before export???
or after import??
Your time is highly appreciated.
Thanks
creddy

Per CU&UC guide, you can do some conversions in parellel
and after upgrade, you have to perform preparation steps and then export, that is what i am following.
What you said is right for single code page conversion method.
upgrade first
unicode conversion second.
I am following CU&UC method.
Thanks

Job logs from the original system after Unicode conversion.

Dear Globalization experts,
We are doing Unicode conversion and would like to know, if the Job logs from the batch jobs, executed before conversion (system with a 1100 code page), would be readable in the Unicode system after the conversion. We will move job log files from the source to the target system. I . Thank you in advance for your help.
Best regards,
Alik Shapiro

Hi Alik,
I have strong doubts that this will work ...
From SAP notes 842767 and 901004 you can see, that spool data will not be converted properly by default.
In general this is valid for data stored in TemSe, as this is by definition temporary data (see for example http://help.sap.com/saphelp_nw70/helpdata/en/d9/4a8f9c51ea11d189570000e829fbbd/content.htm ).
However I actually did not test it, so I am not 100% sure.

Clarfication of steps in Unicode Conversion

Hello All,
Currently we are upgrading from 4.6C non-unicode to ECC 6.0 with Enhancement Package 4 unicode. I have read the guide for Combined Upgrade and Unicode conversion and understand that as pre-requisite we need to execute the following steps:
Execute report for SDBI_CLUSTER_CHECK for initial cluster records
RADNTLANG - Text language for customer objects
Can you please let me know should I execute this in 4.6C system itself or just before exporting. I have tried these reports in 4.6C system itself but the program do not exists. Hence i assume that this should be done just before export. Can anyone please confirm the same?
Regards,
Anand

You will need to check CU&UC guide, there is mentioned also minimum SP level etc.
I recommend to check also unicode wiki page: http://wiki.sdn.sap.com/wiki/display/unicode/Main

Combined Upgrade and Unicode conversion of Sap 4.6C to ECC6.0

Hello all,
my project team intends to carry out a combined upgrade and unicode conversion of an SAP ERP 4.6C system with MDMP to ECC6.0 (no enhancement package). The system is running on Oracle 10.2.
In preparation for this upgrade, I have gone through the SAP notes 928729, 54801.
We need to get a rough estimate of the entire downtime so as to alert our end users. From the CU&UC documentation in 928729, I read up note 857081. However the program in this note cannot be used to estimate the downtime as my system is < SAP netweaver 6.20.
Is there any other SAP note or tool or program that I can use to estimate the downtime for the entire CU&UC? Thanks a lot!

Hi,
Combined upgrade depend upon number of factors like database size, resources on the server and optimization. In order to get idea of how much downtime, it will take, I would suggest you to do combined upgrade and unicode conversion on sandbox system which should be the replica of your production system. And try to optimize it. From there you can get approx. downtime required.
Also, please read combined upgrade and unicode conversion guides on http://service.sap.com/unicode@sap
Thanks

Preparing for upgrade and Unicode conversion while on 4.6c

We're currently on 4.6c and preparing to upgrade to ERP 2005 and do a Unicode conversion. I'm trying to compile a list of coding techniques that can used in 4.6c that will minimize changes needed for Unicode. Does anyone have such a list?
Some things I've discovered reading about Unicode include:
1) Use GUI_UPLOAD and GUI_DOWNLOAD rather than WS_UPLOAD and WS_DOWNLOAD.
2) Structures or table headers that contain non-character data need to be identical when moving, comparing, selecting into, updating from, etc. This includes not moving structures/tables with non-character data to a character field or vice-versa.
3) Offsets can't cross non-character data.
4) Assign statement with offset must specify a length.
5) Open dataset must specify "FOR INPUT", "FOR OUTPUT", "FOR APPENDING", or "FOR UPDATE". It no longer defaults to FOR INPUT when omitted.
6) Many implicit conversions from char to numeric are no longer allowed. Use explicit conversion instead; such as the move statement.
I know there are others. Any help would be appreciated.

Mark Perrey

4.7EEx1.10 to ECC6.0 upgrade and Unicode conversion

Hi Experts,
We are going to initiate the upgrade from next month onwards. Subsequently i have started preparing the plan and strategy for the same.
As our current setup is 4.7EEx110/Win 2003 R2-64 bit/Oracle 10.2.0.4.0 (Non unicode). And we have recently migrated on to this setup from WIn2k 32 bit. Also the current hardware is Unicode compatible.
With respect to strategy for achieving this Upgrade and Unicode conversion, i am planning as follows.
Step 1) Perform Unicode conversion on the current landscape (Both Export/import on the same servers)
Step 2) Setup Temporary landscape as part of Dual maintenance strategy and migrate data from the current systems to temporary systems using backup/restore method.
Step 3) Perform the SAP version upgrade on the current landscape and setup transport routes from temporary to current landscape in order to keep it in sync
Step 4) after successful upgrade, decommission the temporary landscape
Please provide your suggestions and valuable advices if there is anything wrong with my strategy and execution plan.
Regards,
Dheeraj

Hi,
Thanks. As i have already referred these notes as i am seeking advise with respect to my upgrade approach.
However i have planned to perform in the following manner.
1) Refresh Sandbox with Prod data and perform Upgrade to ECC6.0 EHP5 & subsequently Unicode conversion on the same server (Since both export & Import has to perform on the same hardware as we have recently migrated on this hardware which is Unicode compatible)
2) Setup temporary landscape for DEv & QAs and establish transport connection to Production system in order to move urgent changes
3) Keep a track of the changes which have transported during upgrade phase so that the same can be implemented in the upgraded systems i.e. Dev & QAS
4) After Sandbox Migration and signoff, we will perform Dev & QAS upgrade & unicode conversion on the same hardware (Note: Since these are running on VMware can we export the data from the upgraded system and import on to a new VM?)
5) Plan for production cutover and Upgrade the Prod system to ECC6.0 Ehp5 and then Unicode conversion. As i am planning to perform upgrade over the weekend and then Unicode conversion activity in the next weekend (Is it a right way?)
My Production setup: DB on one Physical host and CI on separate Virtual host
6) After the stabilization phase, we are planning for OS & DB upgrade as follows:
a) Windows upgrade from 2003 R2 to Windows 2008 R2
b) Oracle Upgrade from 10.2 to 11.2
If anyone thinks that there is anything wrong with my above approach and need changes then please revert.
I have one more doubt as I am going to upgrade 4.7EEx110 (WAS 620, Basis SP64) to ECC6.0 EHp5.As I presume that I can straight away upgrade from the current version to ECC6.0 Ehp5 without installing EHP. Kindly confirm
Thanks

Wrong text in ADRC and LFA1 table after Unicode conversion

Hello,
We are doing MDMP to Unicode on SAP 4.7 system.
In post unicode activities,we had corrected the garbage characters in
table ADRC
by converting to target langauage ZH using SUMG t-code.
Condition used for addind table ADRC in SUMG is LANGU ='1' and
LANGU_CREA = 'EN'
But after converting and saving the data,most of the records have
incorrect character in word.
and text field of search term/company name/city in table LFA1 are also
wrong in correspond field in table ADRC.
Thanks
Harshavardhan

Hi Harshavardhan,
Assumption: You have Chinese entries in table ADRC with ADRC-LANGU_CREA = EN
Now you have to distinguish two problems:
1) Chinese texts are stored in ADRC fields, which are NOT used for search help texts (most of the fields - e.g. ADRC-NAME1):
These texts can be handled in two ways:
a) Change LANGU_CREA = EN to LANGU_CREA = ZH for these entries (e.g. where ADRC-COUNTRY = CN) before the Unicode conversion (by the way, I would not use ADRC-LANGU, since this is the communication language, which does not necessarily comply with the code page of the entry).
This needs to be done in a similar way as shown in z-reports described in SAP Note 634839 ( although this specific fool-the-system case is not covered there - you have to adapt those examples)
b) Use SUMG to repair the entries using language ZH (as you already did)
My favourite would be a), as this can be done before the conversion (Note that SUMG ineeds to be executed during downtime !)
2) Chinese texts are stored in ADRC fields, which are used for search help texts (e.g. ADRC-MC_NAME1):
a) If these entries were inserted / changed with logon language ZH, then point 1) applies
b) If users logged on with logon language EN and created the entries, then most of these texts are destroyed already in Non-Unicode system. Then there is no automatic repair possible (at least point 1 does not work). Here my statement from before is valid:
Those entries need to be generated again - e.g. if you do a dummy change on the name.
According to my knowledge, this is a manual effort (either before or after the conversion) - but maybe it can be automized ...

Combined Upgrade and Unicode conversion question

Hello Everyone,
I will be performing combined Upgrade and Unicode conversion soon. Currently i have run Prepare and do not have any errors.
I have already run SPUMG consistency check and i do not have any errors there. Since this is Combined Upgrade and unicode conversion according to guide i do not need to do the Nametab conversion right now. But now if i go this place:
SPUMG -> Status -> Additional Information , i see a status with red for Unicode nametabs are not consistent or not up-to-date.
Please let me know if i can ignore this step and do the nametab conversion after upgrade is complete and before unicode conversion.
Thanks,
FBK

Please follow the instructions from the guides.
The Unicode nametabs will be generated automatically during the upgrade.
An additional check is integrated into the final preparation steps in the target releases.

Ronald

Single Code Page Unicode conversion when source and target are the same

Hi everyone. We have recently upgraded our non-unicode 4.7 to ECC6 non-unicode. Now we have begun researching the next step to convert to Unicode. I know we could have done the Combined Upgrade and Unicode Conversion but I wanted to do thorough testing after the upgrade to eliminate too many variables if problems arose.
So, my question is...has anyone done the Unicode conversion when source and target servers are the same? Most documentation I've seen recommends a system copy to another box first. I did find one forum thread that gave a high level approach to doing the conversion with just one server and listed this:
Step 1:- Run Tcode SPUMG to scan
Step 2:- Export Database
Step 3:- Drop Database
Step 4:- Create New Database
Step 5:- Import database
Step 6:- Chnage unicode Kernel
What are your thoughts? Is it supported? Am I wasting my time and should I just bite the bullet and buy yet another system? Thanks in advance.
-Anthony

Theoretically that's possible, yes. However...
> Step 5:- Import database
> Step 6:- Chnage unicode Kernel
the import must be done using the Unicode kernel.
So basically you can
- export the old systm
- uninstall system + database
- start as if you were installing "from scratch" on a new box

Hi Vinay,
did you already check attachment of SAP note 765475 - "Unicode conversion Troubleshooting guide" ?
Excerpt:
...check if the entries in
<table name> still exist. In some cases those entries only exist in the
Twin System but no longer in the Production System. In such cases the
message is not an error message but only information.
Best regards,
