SAP Client concept

If you remember SAP, while you are in, it has 800 mentions the customer (or any other 3-digit number). Think of a customer as a logical separation within an instance of SAP. The "name" client may seem strange to describe a method for separating a bit 'a logical database. But in the days of SAP R / 2, when SAP was used to run on a mainframe resources rather narrow, and many customers host their applications on a single system. And each of these logicalThe systems were said to be a "client.

Data and processes in a client) has no effect on other customers (at one point. For example, if a customer order is created in client 810 and another 820 order is created on the client, are completely independent. A client offers clean, logical separation of business processes. Similarly, customers have created 800 in the client does not mean that customers would have the sameother customers explicitly created only.

Although the business data is different in different clients, there are some independent data from the client. So, changes to client-independent data refers to the entire SAP instance.

If you have a list of all of them in the instance, goto transaction [SCC4]. The following image shows all of them in an ECC 6.0 IDES system. However, it would be a new non-installation of SAP IDES ECC 6.0default 000, 001 and 066th

066 is called Early Clock - This is reserved for access to the SAP system and correct problems.

000 contains only the individual data. This does not include the data and transaction data in a non-IDES. 001 is a replica of the 000th

Employee data

If you look at the data as a function - say Customer Master - KNA1, there is a field called Client (technical name is Mandt). If you are in athe customer 800, one sees only the data for 800th However, the table of the database contains data for customers in all of them. This is why you always give the client application in.Typically transactions and master data is always dependent. The personalization data is client-dependent. For an ABAP developer, it might make more sense when it comes to SQL.

SELECT NAME1, NAME2 from where KNA1 KUNNR = "0000000.001000"
