Effort estimate (ABAP) during Unicode Conversion project

Hi ,
I am working on a CU&UC (Combined Upgrade and Unicode Conversion) project from 46C to ECC6.
We are having 8 different codepages (MDMP SYSTEM) and around 10000 custom objects.
Does anyone have any experince in doing such kind of project ? I am looking at the effort estimate on technical side (ABAP) and functional side.
Any inputs of Technical effort in such a project with related number of codepages and custom objects will be useful (in man days & project duration).
Thanks
Dilip

Hi Dilip,
the main effort from ABAP side seems to be testing of the new system and creating the Unicode vocabulary. You need test teams and test plans for all locations and for the vocabulary you need people for all your languages. ABAP coding itself is probably not your biggest problem. You have to switch your system to unicode and then check all your sources. This could be done by a report or transaction (check the documentation regarding the Migration). From my point of view this is the main effort you'll have, testing and building the vocabulary. How big this effort is depends on your system. I think six month are a good time frame for the whole project (I assume you migrate a landscape of 3 systems). Because I'm working in the Basis administration I could not tell you the exact man days, but I would estimate up to two weeks for the vocabulary per language. You should have the numbers for the system tests from previous upgrades.
The technical migration effort depends on your hardware and time requirements. If your system is big (TBytes) and your downtime is very limited it could be necessary to tune the migration by testing it several times. If your requirements are not that high, then a single test migration could be sufficient. I've done two bigger migrations with 2.5 and 3.5 TB in less than 24 hours but therefore you have to have fast hardware and you have to tune your process well. If you have a single huge table this could destroy all efforts reaching your time target, if for example the index build could not be done in less then your time target. If you have enough hardware resources and time to tune your migration you could reach almost any time (which makes sense - some hours).

Error during unicode conversion

Dear all,
we are facing one issue during unicode conversion. the code is as follows:
FIELD-SYMBOLS : <n> TYPE X,
                             <c> TYPE C.
DATA : a TYPE i.
DATA : x TYPE x.
MOVE <n> TO a.
a = a + 22.
MOVE a TO x.
ASSIGN x TO <c> CASTING TYPE c
and we are getting the following error:
ERROR : the length of "X" in bytes must be a multiple of the size of a Unicode character (regardless of the size of the unicode character
please guide on how this can be resolved in ECC.

Hi,
here is some code to do it:
FIELD-SYMBOLS : <n> TYPE x,
                <c> TYPE c.

MOVE <n> TO a.
a = a + 22.

Performance during Unicode Conversion

Hello,
currently we are planning to do a Unicode Conversion on a Linux/MaxDB System.
The DB has a size of approx. 350 GB. The system runs on Fujitsu-Siemens FlexFrame hardware.
One problem is that during a test conversion the export of the DB took more than 24 hours.
This seems too much regarding the DB size.
We know that filesystem and RAM and CPUs influence the export duration.
What possibilities do we have to tune the export with "software" tools?
- table splitting
For example: Our largest table has ~26GB datasize.
How do we split this table?
In 10 parts or in 20 or in 200?
If you could please post your experiences.
Regards, Michael

I don´t wanna discourage you but I´m not sure if splitting that single table will help alot.
The problem with this combination is the fact, that the MaxDB database reads data block-by-block, means, exeucting single I/Os for each block to read. Given that fact and the fact, that each I/O will be ran over an NFS (with the known latency) it´s unlikely that you will get much more speed out of this.
The problem is NOT the speed between the NAS and the database server, if you will look on the network traffic you will see, that there´s plenty left. The problem is the latency on the client side (the database server) when you put your files on NFS.
I can export a 250 GB database in under 3 hours (admittedly - without UC conversion) using a direct fibrechannel connection (so non-NFS) so the database itself is certainly not the problem, it´s the combination of the usage of NFS (no matter if v2 or v3) and the way the MaxDB database reads data.
I´ve been involved in a likewise project and with a NetApp specialist and some in-depth tuning we were able to gain 15 - 20 % speed but not more.

Hi Volker,
Thank you very much. Stupid error :-).
I also did step 2 with fixr3owns yesterday with SAPINST and then it worked. I got to step 3 "iSeries Installation Step", but got an error in SAPINST when "Creating infrastructure for SAP system BND". I logged off SAPINST, patched CRTR3SYS and started SAPINST again and then got the error in step 2 wirh fixr3owns.
I´m now past step 2 and in step 3 "iSeries Installation Step". And I get the same error as I got yesterday...
From the job log:

I can run "CRTR3SYS SID(BND) GLOBALHOST('SAP002') FORCEPROF(*NO)" manually.
Do you have any ideas?

Error during Unicode Conversion at DDNTF table

Hello
We are doing a Unicode Conversion for our CRT systems. This system now
is a SAP CRM 7.0 SR1 ABAP.
We have performed preparatory steps (SPUMG, checks, updating R3load,
R3ldctl, R3szchk, dboralib, ...),
but when we start Import process we get an error in SAPSDIC package.
The error looks like:

Any idea??
Thanks in advance

Yes I executed this Report using Menu Tool Bar.
The first execution gave me some errors regarding some tables existing at database level but not in DDIC. We ignored this errrors because those tables are not important.
But the last try, we decided solve this inconsistencies deleteting those tables at database level, repeting report RADUCNT (in this case no errors appeared) and repeting the export with the same error..
Now, we have seen in Tabscript STATUS of SPUMG there are some errors regarding DDNTF inconsistency found at table control. Reason 4. But this reason means that faillback codepage missing at table control for this table. But as far I know, I can't fill failbak field for this kind of table...
So know I'm reseting SPUMG, and reestarting again..
But I don't understand what is the problem
In a few minutes I will you inform about results
Meanwhile is anybody have any suggestion or idea... please let me know
Thanks!

Usage of Conversion Classes During Unicode Conversion

Hi,
I have code
"TRANSLATE BBKF-SGTXT FROM CODE PAGE '0100' TO '0120'" Now During Unicode i need to Use the Conversion classes
Can any one help to proceede further on this
Actually I am using CL_ABAP_CONV_OUT_CE and I am getting the Data in Binary Format But I want that to be in Character format can any one suggest me
Thanks & Regards,
Prasad

Do you have an EBCDIC system with code page 0100? (check it using SNLS transaction)
In that case, CL_ABAP_CONV_OUT_CE is okay.
After having converted to code page 0120 (into xstring), here is how to cast xstring variable to character.
DATA x TYPE x LENGTH 800. " so that to compile, x length
" must be a multiple of 4 (don't ask why)
FIELD-SYMBOLS <c> TYPE c.
x = xstring. "make sure x is long enough
ASSIGN x TO <c> CASTING.
BBKF-SGTXT = <c>.

LRAW data Conversion during Unicode Conversion

Hi,
We have upgraded our 46C MDMP system to Unicode system.
After conversion we found that some of the tables with field of LRAW type are having conversion issue.
In 46C system, Russian data which enetered in the MS Cyrillic (Code page 1504), is converted to code page 1500 after unicode conversion.
We have not found any entries for this table in vocabulary, reprocess log or in SUMG.
For example table STXL. This table contains Purchase order text for the material.
Report HRUU_CONVERT_IN_UNICODE does not shows LRAW data field for conversion.
Can you suggest how LRAW data can be converted from 1500 to 1504 code page.
Thanks and Regards
Rahul

Hi Rahul,
STXL is a language dependent INDX type table. Hence SPUMG will not scan this one with the default settings.
Please have a look at the description of INDX type table handling in the Unicode conversion Guide.
In the Unicode system, you can use UMG_ADJUST_STXL for the conversion.
However please be aware of the restrictions:
Once you have decided about the code page and converted the object, this cannot be reverted !
Therefore it is highly recommended to check the display mode first and in addition test it extensively on a sandbox system !

Skipped tables during UNICODE conversion

Hello everybody.
We are making a unicode conversion in a 701 Ehp4 over iSeries.
The export has finished succesfully but we have detected that some tables have been skipped. In the Export_monitor.log there are some comments like this one:
INFO: 2010-04-15 01:30:56 com.sap.inst.migmon.LoadTask processPackage
Unloading of 'AGKO' export package from database will be skipped.
Task file '/usr/sap/SAPinst/NW04S/EXP/AGKO.TSK' is empty and contains no tasks.
Does anyone know why have these tables been skipped?
Do we have to repeat all the process?

R/3 Export & Import during Unicod Conversion via SOCKET Method

Hi
We are in the process of upgrading our R/3 Enterprise to ECC 6.0. The size of the database is around 4 TeraBytes.
Can somebody help us with necessary documentation/ othe rinputs to handle R/3 Export & Import using SOCKET method? FYI we referred the SAP given doucments on the same. Any particular DOs & DO NOTs would be highly appreciated.
Thank You
Sai

Hi Rahul
regarding your 'Unicode doubt"' some ideas:
1) The Upgrade Master Guide SAP ERP 6.0 and the Master Guide SAP ERP 6.0 include introductory information. Among other, these guides reference the SAP Service Marketplace-location http://service.sap.com/unicode@sap.
2) In Unicode@SAP can you find several (content-mighty) FAQs
Conclusion from the FAQ: First of all your strategy needs to follow your busienss model (which we can not see from here):
Example. The "Upgrade to mySAP ERP 2005"-FAQ includes interesting remarks in section "DO CUSTOMERS NEED TO CONVERT TO A UNICODE-COMPLIANT ENVIRONMENT?"
"...The Unicode conversion depends on the customer situation....
... - If your organization runs a single code page system prior to the upgrade to mySAP ERP 2005, then the use of Unicode is not mandatory. ..... However, using Unicode is recommended if the system is deployed globally to facilitate interfaces and connections.
- If your organization uses Multiple Display Multiple Processing (MDMP) .... the use of Unicode is mandatory for the mySAP ERP 2005 upgrade....."
In the Technical Unicode FAQ you read under "What are the advantages of Unicode ...", that "Proper usage of JAVA is only possible with Unicode systems (for example, ESS/MSS or interfaces to Enterprise Portal). ....
=> Depending on the fact if your systems support global processes, or depending on your use of Java Applications, your strategy might need to look different
3) In particular in view of your 3rd option, I recommend you to take a look into these FAQs, if not already done.
Remark: mySAP ERP 2005 is the former name of the application, which is named SAP ERP 6.0, now
regards, and HTH, Andreas R

Minimize downtime during UNICODE conversion

Hello forum !
I am looking at the UNICODE conversion of a large (?) SAP Oracle database for ECC. The Database it self is at about 10 TB. UNICODE converting this in one single run will take too long to fit inside the company defined tolerable downtime window.
When looking at the data I find that the largest 50 tables makes up about 75% of the total database size. Most of the 50 largest tables have data for several years back, and I am able to partition the tables with one partition pr year.
The good thing about this is that I am able to make the partitions with old data (more than one year old data) READ-ONLY.
My assumption is that I will be able to UNICODE convert 60-70% and create the indexes for these partitions without taking down the database to be converted.
Now,- doing the downtime-phase I will be able to exclude the old partitions of the largest tables in the export since I have already created a new UNICODE database with these objects and thereby drastically reducing the required downtime.
Is there anyone who has any experience with an approach like the one I have schetched out here ?
Kjell Erik Furnes

Can you please be a bit more specific on your installation? How long is your possible downtime (export time should be about 2/3 of that)? How long is your actual export estimation? Do you have suitable hardware (CPU/disk)?
What you absolutely need to have:
[1043380 - Efficient Table Splitting for Oracle Databases|https://service.sap.com/sap/support/notes/1043380] -> export tables with ROWID splitting
[855772 - Distribution Monitor|https://service.sap.com/sap/support/notes/855772] -> enables distributed and parallel export/import
So on the hardware side you will need, a storage subsystem as fast as possible with two copies of the disks (one for exporting and one for importing). A bunch of application servers with fast CPUs helps a lot, everything connected with at least gigabit ethernet.
If you knew all this already, sorry for the spam. But i achived throughputs at about 400gb/hour on a medium sized hardware, i think throughputs of 1tb/hour should be possible (not talking about cluster tables
