Which of the following statements about interfaces are correct?
More than one answer is correct. Decide whether each answer is true or false. Interfaces represent a separation between an interface and implementation (class), for which the client defines the protocol (interface) and the server (implementing class) implements it A client (caller) can use interface to access all interface methods and thus active polymorphic behavior Interface are used to call the static components of a class Using interfaces, you can simulate interface Using interfaces, you can reference all the public components of an object that have been defined in the corresponding interface implementing class.

Which commands are allowed if you are working with an internal table of type SORTED? SORT DELETE INSERT READ TABLE MODIFY.
DATA: itab TYPE tt_spfli. Parameters: pa_carr TYPE spfli-carrid. AUTHORITY-CHECK OBJECT ‘S_CARRID’ ID’CARRID’ FIELD pa_carr ID’ACTVT’ FIELD ‘03’. SELECT * FROM spfli INTO TABLE itab WHERE carrid = pa_carr. What happens when the above program component is executed?
Choose the correct answer If the user does not have the relevant authorizations in his or her master record, the system leaves the current event block directly after the AUTHORITY-CHECK command and jumps to the next event block. In this case, the SELECT statement is not executed Regardless of whether or not the user has the relevant authorizations in his or her master record, the SELECT statement is executed and the data read from the database If the user does not have the relevant authorizations in this or her master record, the SELECT statement is not executed, since in this case , the AUTHORITY-CHECK always determines the program automatically.

You write an application that stores data in an internal table temporarily. Since the application is runtime critical, you consider which type of internal table to use.
Which statements about internal tables are correct? You can not use an index to access hashed tables You can use the INSERT TABLE statement to add data records to all types of internal table There are four types of internal table: standard, sorted, hashed, and indexed tables If not all key fields are when a data record is read from an internal table with table key (READ… WITH TABLE KEY…), the statement returns the first suitable data record If you want to add an entry to a sorted table, the sort sequence must remain the same.
In your application, you implement diverse calculations. In the calculation, you use variables of data type f, p, and i. Which arithmetic does the calculation follow? Calculations are basically carried out in integral arithmetic. The result is converted to the type of result variables The ABAP runtime always uses packed numbers for business calculations. This means that this calculation is also carried out with packed numbers and, if necessary, the result is converted If the arithmetic expression contains a data object of type f, calculations are basically carried out in floating point arithmetic.

Which statements apply to dialog programs that change databases? When the asynchronous update is used, the COMMIT WORK statement is not required, since it is executed implicitly after each screen change All inline changes must be executed in the PAI of the last screen in order to ensure the rollback capability of SAP-LUW In the PAI of each screen, you must use the COMMIT WORK statement When the asynchronous update is used, database changes are made directly by the program When the asynchronous update is used, set SAP locks are transferred to the update procedure so that they do not have to be removed in the actual dialog program.
You are calling an update function using CALL FUNCTION… IN UPDATE TASK. At what event are the values of the function parameters detemined? At the time of the call At COMMIT WORK At the start of the function execution.
Why must logical SAP locks and not database locks be set in dialog programs to prevent concurrent data accesses? Because SAP locks are more efficient than database locks Because set database locks may be implicitly removed before the changes have been made to the data Because SAP locks are more up to date and easier to maintain than database locks.

For what purpose are foreign keys(FK) defined in the ABAP Dictionary? FKs are used solely for documentation table relationships For the purpose of data consistency; When you maintain data records using dialog transactions (screens), the input values are automatically checked in accordance with the FKs For the purpose of data consistency; when you activate the table, the FKs are created in the database. You thus prevent invalid data from getting into the table.
