The values from minimum to maximum provided in the selection screens are called the number ranges. A select option declares an internal table, which is automatically filled with values or ranges of values, entered by the end user. For each select option, the system creates a selection table. A selection table is an internal table with fields Sign, Option, Low and High. The type of Low and High is the same as that of <field>. The SIGN field can take the following values: I Inclusive (should apply) E Exclusive (should not apply) The option field can take the following values: EQ Equal GT Greater than NE Not equal BT Between LE Less than or equal NB Not between LT Less than CP Contains pattern GE Greater than or equal NP No pattern. The parameters allow users to enter a single value in an internal field within a report. Select options allow users to fill an internal table with a range of values. For each Parameters or Select Options statement you should define text elements by choosing. Goto - Text elements - Selection texts - Change. When the user executes the ABAP/4 program, an input field for 'name' will appear on the selection screen. You can change the comments on the left side of the input fields by using text elements as described in Selection Texts.

Match codes are similar to table index that gives list of possible values for either primary keys or non-primary keys.

If a table is activated in DD it would be available for any insertion, modification and updating of records by any user.

The table, which is at the field level checking, is called Check table, the table that will be at domain level checking, is called as value table. Tables, Views, Structures, Lock Objects, Match Code Objects are some of the data dictionary Objects.  

The exceptions in functional module are Communication Failure and System Failure.

The groups of all related Functions are called Function Group and the date and time field values are stored as DD.MM.YYYY and HH:MM:SS in SAP.

The Interactive Report where the user can get more than the relevant data by selecting explicitly is called as the Drill down Report.

Drill Down report is an Interactive Report where the user can get more relevant data by selecting explicitly.

The dynamic drill down report that produces the list on user’s choice is called Interactive Report. When compared with classical type reports, the list produced by classical report doesn’t allow user to interact with the system, the list produced by interactive report allows the user to interact with the system. Once a classical report executed user looses control IR user has control. In classical report drilling is not possible in interactive drilling is possible.
