Parameter transactions

Parameter transactions allow basically to create a customer specific transaction
with preset values already in the initial screen.
This is a helpful feature if ist for example required to grant access to certain tables/views.
Usually the access can only be restricted to the authorization group level,
and with that access is granted always to the corresponding tables that are
assigned to this group.
A parameter transaction allows to “connect” a view to a customer specific

Batch-Input Sessions

Several data processing methods are based on Batch Data Communication
(BDC) as a Batch interface technique provided by SAP®.
This technique allows the import or processing of data in dialog mode by
basically simulating the user input via transaction.

As for the import, the data is stored in a sequential file and is then imported via
Batch-Input interface program into a Batch-Input Session.
This procedure is used for data import from legacy systems as well as for

Change documents

SAP® provides different techniques to fulfil the legal requirements related
to change history. One is the logging of table changes ;
another technique is realised with the help of change documents.

Change documents only keep track of changes. Tracking the creation of
data records is not part of it. The change documents are controlled via

SAP® profile parameters

The system parameters are stored in text files on the operating system level
in the global profile directory. Changes to profile parameters may not be done
 in the text file directly, but only through a corresponding transaction within
SAP® [e.g. RZ10], otherwise the change history will not be complete.
Therefore and because of the risk of potential file violations the access

SAP® table buffering

SAP® stores almost all data in tables. These tables are part of the underlying
database. With that SAP® would need to execute a high number of database
calls every time a corresponding information is required.
As part of a network in client-server environments this would be a time and
resource consuming task with negative impact on system performance.
To reduce the corresponding workload SAP® has established a table buffer

SAP® NetWeaver security parameter
The SAP® NetWeaver is a comprehensive application and integration platform
that consists of several components and tools.
Important components are e.g.  the NetWeaver Application Server,
NW  Business Intelligence, NW Exchange Infrastructure,
NW Master Data Management, NW Mobile, NW Portal,
Auto-ID infrastructure, NW Identity management.
Relevant tools are e.g. Adaptive Computing Controller,

ABAP/4® Developments
Development in general is about the creation of new objects
or the modification of existing objects.
One language for programming in the SAP® environment is ABAP/4®
[Advanced Business Application Programming].
Developments are supposed to be performed in the development system only,
and from there they are technically transported with the help of the Transport Management System [transaction STMS] through the Quality-system into the
