can, for example, read particular entries from one or more large customer tables into an
internal table, and then use them to create a list. When you run your program, you can
access this data directly, instead of having to search for each record in the database.
What is a variant and where do you use it?
If you want to run a report program with same selections at regular intervals (for
example, for monthly sales statistics), you would not want to enter the same values each
time. So, ABAP/4 offers you a possibility to combine the desired values for all these
selections in one selection set. You can create as many different selection sets as you
like for each report program and they remain assigned only to the report program in
question. Such a selection set is called a variant.
Using Variants Online
Using Variants in Background Processing
Online, starting a report via variant saves the user work,minimizes input errors. In
background processing, a variant is the only possibility you have to pass values for the
selections.
To fill certain selections with values that change according to the application, you use a
variant, which takes the variable values from Table TVARV.
What is set parameter and get parameter?
We can pass data to a called program using SPA/GPA parameters. SPA/GPA
parameters are field values saved globally in memory. Each parameter is identified by a
three-character code: you can define these parameters in the object browser by
selecting Other objects on the first screen. The SPA/GPA storage is user-specific and
valid throughout all the user's sessions.by using the SET PARAMETER or GET
PARAMETER statements
These statements let you store and retrieve SPA/GPA values from an ABAP/4 program.
If the selection screens for the two transactions do not share the same required fields,
use these statements to store screen fields explicitly by name.
Before calling the new transaction from a PAI module, store the caller transaction's fields
under one name:
SET PARAMETER ID 'RID' FIELD <FIELD NAME1>.
The system stores the value in <field name1> in the SPA parameter 'RID'. The three-
character identifier 'RID' must be defined in the SAP table TPARA. If the SPA parameter
'RID' already contains a value, the SET PARAMETER statement overwrites it (with the
contents of <FIELD NAME1>).
In the PBO module for the called transaction, retrieve the fields under the other name:
GET PARAMTER ID 'RID' FIELD <FIELD NAME2>.
What is field symbol?
A field symbol does not physically reserve space for a field, but points to a field
which is not known until runtime of the program. Sometimes you only know which field
