    ALL The Best

    1. The search help function know various link options in the ABAP dictionary. Which of thefollowing statements apply !elect the True

    A search help function that is linked to the data element can return values only

    for the search field "field where the f# help was triggered$

    %f the search help function is linked to the data element as well as to the field.

    The search help for the field is displayed

    A search help function that is linked to the ta&le field can return values only for

    the search field "field where the f# help was triggered$

    %f the search help function is linked to a ta&le A. this search help displayed

    whenever there are input fields on that screen that have A as the check ta&le

    '. %s it possi&le to increase the num&er of key fields in transparent ta&les that are already

    active

    (es) irrespective of whether the ta&le already contains data or not

    *o) +ey changes are not allowed

    (es) ,owever) the ta&le must not contain any data yet.

    -. hanges to active transparent ta&les/ The type for the non0key field is to &e changed

    from *2 to ,A3. What follow0up actions are to &e e4pected !elect True "yes$.

    %f the ta&le does not contain any data yet) the ta&le only needs to &e activated. %n

    this case) you delete the old ta&le from the data&ase and afterwards you recreate

    the changed structure

    %f the ta&le already contains data) this change needs to &e e4ecuted first in the

    data&ase &y the data&ase administrator. Afterwards) you can reactivate the ta&le

    in the 5ictionary

    %f the ta&le already contains data) you have two options/ 6ither the data&ase can

    show this change with the statement ALT63 TABL6) or you trigger a conversionprocess from within the !AP !ystem

    Type changes in the 5ictionary are supported for key fields only. %n the case of

    non0key fields) such changes can &e e4ecuted only &y the data&ase

    administrator using special data&ase techni7ues

    #. (ou want change the technical properties that are defined in a domain. ,ow do you

    proceed8which statements are correct !elect True

    %f a dependent o&9ect is a transparent ta&le that already contains data) the ta&le

    in the data&ase may have to &e converted

    :nce changes have &een made and the domain activated) you have to reactivate

    each dependent o&9ect individually

    Before you make any changes) use a where0used list to search for dependent

    o&9ects) since the changes can continue to the fields in structures and data&ase

    ta&les

    (ou make the changes immediately) since) initially) an inactive version is created

    for all dependent o&9ects that contain these changes

    ;. Which of the following statements a&out the !AP ta&le &uffer are correct !elect True

    1. 6ach application server involved in an !AP !ystem has its own ta&le &uffer

    '. Large ta&les must &e &uffered as completely as possi&le

    -. When ta&les are &uffered in the !AP ta&le &uffer) inconsistencies can occur &etween

    the status in the !AP ta&le &uffer and the status in the data&ase.

    . ?or what purpose are foreign key "?+$ defined in the ABAP 5ictionary !elect True

    ?or the propose data consistency/ when you maintain data records using dialog

    transaction "screens$.

    The input values are automatically check in accordance with the ?+s.

    ?+s are used solely for documenting ta&le relationships

    ?or the purpose of data consistency/ when you active the ta&le the ?+s is

    created in the data&ase. (ou thus prevent invalid data from getting into the ta&le.

    1E. %n the case of classes) we distinguish &etween two types of components "attri&utes and

    methods$/ %nstance components and static components. Which of the following

    statements apply in this conte4t yes.

    !tatic methods can &e called through the class/

    FclassnameGGFmethodnameG

    %nstance methods can use &oth static as well as instance components in their

    implementation part.

    !tatic attri&utes e4ist only once for each class

    %n a static method) instance attri&utes can also &e used) provided they are

    declared as 36A5 :*L(

    Both static as well as instance attri&utes are declared using the 5ATA statement.

    11. sing the statement 36AT6 :BD6T you can instantiate o&9ects of a class. Whatsituations can arise here

    (ou can preset different o&9ects of a class with different values immediately when

    they are &eing created

    (ou define the type and num&er of attri&utes of an o&9ect through the

    corresponding class.

    All o&9ects of the same class contain the same num&er of attri&utes and methods

    after &eing created.

    The contents of the attri&utes of different o&9ects in a class always contain the

    #.A client "caller$ can use interface reference to access all methods of the interfaces and

    thus archive polymorphism &ehavior.

    o&9ects class

    %f you have numeric interface parameter in an ABAP :&9ects class. (ou can do

    without typing.

    To simplify writing the software and design it clearly) you can do without typing

    altogether within the ABAP o&9ect classes.
