Client 000, 001 and 066

[corinne_lofts]

Hi everyone,

Pretty new to SAP.

I am struggling to find answers to the following questions:

How do you use client 000, 001 and 066?

Apart from initial installation and support (066) can theses clients be used in development, testing and production environements?

Can 000 and 001 be used as working clients or should they only be used as template?

What should their configurations be when using SCC4 for each system inthe landscape: DEV, QA and PROD (and Solution Manager)

From a security point of view, once SAP*, DDIC have been secured should they be any other users (Dialog, System) in these clients?

Sorry quite a few questions but if anyone could give me direction as I am trying to understand if some of our current settings are correct and if not why.

Thank you

Hi Corinne,

Even though it is a very basic question, it is very essential to understand and find an answer to your questions.

Client 000, 001 and 066 are (as you know) standard clients thats pre-built when you install SAP.

"Apart from initial installation and support (066) can theses clients be used in development, testing and production environements?"

Answer: No, they cannot be used for development, testing or production environments. When I say, "they cannot", I mean they are not supposed to be used.

"Can 000 and 001 be used as working clients or should they only be used as template?"

Answer: Client 000 is basically used as working client only when you do support pack upgrade or ABAP load generations (SGEN) and implementing additional languages, etc. Otherwise, client 000 should not be used as a working client. The same applies to client 001. But the only exception with 001 is, with Solution Manager, 001 will be your working client. You will do all configurations and obtain support from SAP through this client. With other Systems like BW and CRM, this client (001) will not be a working client.

"What should their configurations be when using SCC4 for each system inthe landscape: DEV, QA and PROD (and Solution Manager)"

Answer: In the production system - "Changes and Transports for Client-Specific Objects" should be set to "No Changes allowed". "Cross Client Object Changes" should be set to "Changes to Repository and Cross-Client Customizing Allowed". "Protection: Client copier and comparison Tool" must be set to "Protection Level 1: No Overwriting". Same applies to Quality System and Development System. These are by-the-by default settings also when you install the system.

"From a security point of view, once SAP*, DDIC have been secured should they be any other users (Dialog, System) in these clients?"

Answer: Once you install the system, you must first make a copy of DDIC to any user you create in your name or any standard name. Never use DDIC when you do initial settings after the installation.

Hi

These three clients are default clients provided by SAP.

000 this client is called as golden client which is provided by SAP as refrence client.

001 this client is called as configuration client which have all the SAP standard customizing client.

066 is the earlywatch client for SAP use.

These all three clients are used as template clients and we donot touch them in our landscape.

you can create the clients from SCC4 and copy the golden client to make new further clients for the usage.

logically we donot use SAP* and DDIC and for that we locks these users. We use to crate the new users with same authorizations and does the work with those users. Basically SAP* (super administrator) is the user without usermaster data as it is embedded in the coding but DDIC (used for Data Dictionary tasks) is used for Data dictionary object changes.

Hello Caroline,

000,001 and 066 are default client of SAP that you get at the time of installation.

Out of these 066 is used for early watch report. 000 and 001 contains standard data and should not be changed.

000 can be used for lot of adminsitrative activities like importing support packages.

Users should not make any customising changes on any of these clients.

The best thing to do is to create a new client, copy it from client 000 and then release it for users to work on it.

Regards.

Ruchit.
