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

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

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

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
