How can I know, whether my SAP uses MDMP ?

[Former Member]

Hello together,

how can I know, whether my SAP uses MDMP?

There are different processes to upgrade to UNICODE. One for Systems which have MDMP and one for System which are not using MDMP.

The upgrade path for systems with MDMP is much more complicated than the upgrade path for non MDMP systems.

I found one transaction: smlt

There I can see that we have installed for example hungary and english.

Is this installation using MDMP?

If yes, can I deinstall this languages?

Hello Carsten,

you can check NLS and specially MDMP with reports RSCP0018 and RSCPINST, or have look at table TCPDB. If you fin mor than 1 entry in TCPDB your system is MDMP.

You can not deinstall a language, but you could omit a language for upgrade.

(if you do not need it any more?)

Hello Guido,

in Table TCPDB are two entrys. (1100,1401)

The report RSCP0018 says:

-

---

===========================================================

TCP0D EN Three blank pcs

Use language English precedent in the system

TCPDB

1100 SAP internal, like ISO 8859-1 (00697/00819)

1401 SAP internal, like ISO 8859-2

More than one entry dangerous

===========================================================

Very nice comment from SAP. )

Hello again,

the Report rscpinst shows:

==============================

C o n f i g u r a t i o n T y p e :

Non-Unicode System

Non-Unicode - MDMP configuration

==============================

So I seems to definatly so, that we have MDMP active.

Hello Carsten,

yes, I ran this report RSCP0018 the first time - and it does what was mentioned. It shows you millions of stuff AND the contents of TCPDB - which you could do with SE16 as well ...

yes, you ARE running MDMP ...

I don't remember for sure:

Are you running 4.6C or 4.7 ?

In the case of 4.6C, you have to upgrade first and as you most likely want to upgrade to ECC 6.0, you HAVE to do the Unicode CPC during the upgrade.

In the case, you are on 4.7 or higher, you could do the Unicode CPC at any time after that you upgrade the Basis Packs "up to the roof".

There is no real problem at the moment, except, that SAP does no longer support this configuration with ECC 6.0 and higher

The effort for this MDMP Unicode Conversion is hard to calculate and more or less not really to predict. At least it is necessary to try to reduce the effort wherever you can, in order to not create a project of several weeks effort. Otherwise, if you try to "make everythign 200% correct", it is just not affordable!

Currently I'm doing such a project and we will do it productive between X-mas and new year ...

Gurus,

Any idea what makes any SAP system MDMP system? I know how to check TCPBD / RSCPINST etc. I dont want to know how to know whether system is MDMP or not but I WANT TO KNOW WHAT MAKES SYSTEM MDMP SYSTEM?

Thanks,

Hello,

very easy:

TCPDB is not allowed to contain more than 1 row !

>=2 rows => MDMP !!!

Thanks for the reply. I know its simple to say. But I can have multiple codepage installed on the system & can still use it as single code page system.

For example .....

I can install EN /DE (code page 1100) which is default. & can also install Japanese (code page : 8000).

When I say Single code page .....it uses only code page 8000 to produce the Japanese fonts.

When I say MDMP ....it can use multiple code page (that is 8000 & 1100 too) to produce Japanese fonts.

In short installing multiple language doesnt mean that it is MDMP system. There is something in the system which force the system to use Multi code page or use MDMP technology.

I am trying to find out what is that which force the system or which makes the system MDMP?

Again , I know how to check if its MDMP using (TCPDB / report RSCPINST / report RSCP0018 etc.)

I am trying to find out what is that which force the system or which makes the system MDMP?

I would appreciate any inside on this topic.

Thanks,

Miraj Desai.

Hello,

ok, that is my last try:

1100 & 8000 => MDMP !!!!!

ONLY 8000 => single codepage

ONLY 1100 => single codepage

There is NO switch ....

=> DE & JA cannot work in a NON-MDMP system together

=> EN & JA can work in a NON-MDMP system together

Hello,

I forgot:

1100 & 8000 * in TCPDB * => MDMP !!!!!

so what are the restrictions or limitations , system can not use DE & JA togather in non-MDMP system.

Hi Miraj,

rough rule of thumb (and background info): a system will definitely be an MDMP system if you are trying to install multiple languages, whose characters are not available on the same native ASCII Latin-x codepage.

Thanks for the reply.

I have following two systems & result of RCP0018 is different & strange.

D1 - Develpmnt 1 system

Installed languages / code pages : 1100 , 8400 , 8500 , 8000

Result of RSCP0018 - Non-unicode system

single code page

_D2 - Another development system of HR

Installed languges / code pages : 1100, 8000

Result of RSCP0018 report - MDMP system_

Can somone explain why there is a difference even though multiple code pages have been installed on both the systems.

Thanks,

Miraj Desai.

Hi,

I cannot believe that it is showing you "single codepage" ....

My 4.7 MDMP system reacts as follows:

RSCP0018:

Database table

Value Suppl.

TCP0D

EN Three blank spcs

Use language English precedent in the system

TCPDB

1100 SAP internal, like ISO 8859-1 (00697/00819)

1401 SAP internal, like ISO 8859-2

1500 SAP-internal, like ISO 8859-5

1700 SAP-internal, like ISO 8859-7 (Greek)

1800 SAP-internal, like ISO 8859-8 (Hebrew)

8000 Shift JIS

8400 Simplified Chinese (based on GB2312-EUC, MS CP936)

More than one entry dangerous

=> clearly MDMP

RSCPINST shows the MDMP feature during SIMULATION:

Code page configuration type:

Non-Unicode - MDMP configuration

Attention!

The required language combination is supported without restrictions

only in Unicode systems.

Please refer to SAP Note 73606.

Processed language entry:

RSCPINST will update TCP0I entry when activated.

1BDEFGIJLPRSV

Language(s) and Corresponding Code Page(s):

RSCPINST will update TCPDB entries when activated.

ZH (1) 8400 Simplified Chinese (based on GB2312-EUC, MS CP936)

EN (E) 1100 SAP internal, like ISO 8859-1 (00697/00819)

FR (F) 1100 SAP internal, like ISO 8859-1 (00697/00819)

DE (D) 1100 SAP internal, like ISO 8859-1 (00697/00819)

EL (G) 1700 SAP-internal, like ISO 8859-7 (Greek)

IT (I) 1100 SAP internal, like ISO 8859-1 (00697/00819)

PL (L) 1401 SAP internal, like ISO 8859-2

PT (P) 1100 SAP internal, like ISO 8859-1 (00697/00819)

RU (R) 1500 SAP-internal, like ISO 8859-5

ES (S) 1100 SAP internal, like ISO 8859-1 (00697/00819)

SV (V) 1100 SAP internal, like ISO 8859-1 (00697/00819)

It doesn't matter: There is no further switch - it is just the amount of entries in TCPDB .... 1 is OK - more than 1 is MDMP ...
