1) What is runtime analysis? Have you used this?2) What is meant y !erformance analysis? Have done anythin" to im!rove the

!erformance?#) How to transfer the o$ects? Have to transferred any o$ects?%) How did you test the develo!ed o$ects?

&) What is the difference etween 'AP (emory and ABAP (emory?

) In order to u!load Purchase order details* how you handle multi!le values for a sin"lefield?

+": Item field may contain no, of values for a record

-) What is the !rocedure you followed to u!load the data?

.) How did you handle errors in /all 0ransaction?) Amon" the /all 0ransaction and 'ession (ethod* which is faster?

1) What are the difference etween Interactive and 3rill 3own 4e!orts?

11) How to !ass the variales to forms?12) How to create a lin5 etween modified form and modified !rint !ro"ram?

1#) What is the tale* which contain the details of all the name of the !ro"rams and

forms?1%) How did you test the form u develo!ed? How did you ta5en !rint?

1&) What are 'tandard 0e6ts?

1) What is the difference etween /lustered 0ales and Pooled 0ales?

1-) What is !f7status?1.) Amon" 8(ove8 and 8(ove /orres!ondin"8* which is efficient one?

1) What are the out!ut ty!e and 0codes?

2) Where we use /hain and +ndchain?

21) 3o you use select statement in loo! endloo!* how will e the !erformance? 0oim!rove the !erformance?

22) In select7o!tions* how to "et the default values as current month first date and lastdate y default?

+": 191292% and #191292%

o thru these answers:

1) What is runtime analysis? Have you used this?

It;s chec5s !ro"ram e6ecution time in microseconds, When you "o to se#,if you "ive

desired !ro"ram name in !erformance file, It will ta5e you to elow screen,

I was testin" a develo!ed o$ect, 0here are two ty!es of testin"

7 =e"ative testin"

7 Positive testin"

In ne"ative testin" we will "ive ne"ative data in in!ut and we chec5 any errors occurs,

In !ositive testin" we will "ive !ositive data in in!ut for chec5in" errors,

.) How did you handle errors in /all 0ransaction?

We can create a internal tale li5e ;s"mc"coll;, All the messa"es will "o to internal tale,

We can "et errors in this internal tale,

Below messa"es are "o to internal tale, when you run the call transaction,7 (essa"e ty!e

7 (essa"e id

7 (essa"e =umer7 >ariale1

7 >ariale2

7 >ariale#

) Amon" the /all 0ransaction and 'ession (ethod* which is faster?

/all transaction is faster then session method, But usually we use session method in realtime,,,ecause we can transfer lar"e amount of data from internal tale to dataase and if

any errors in a session, Process will not com!lete until session "et correct,

1) What are the difference etween Interactive and

3rill 3own 4e!orts?

ABAP9% !rovides some interactive events on lists such as A0 I=+7'++/0I@=

doule clic5) or A0 '+47/@((A=3 !ressin" a utton),


3/16

Which contain the details of all the name of the !ro"rams and forms? I don;t 5now),

1#) How did you test the form u develo!ed? How did you ta5en !rint?

1%) What are 'tandard 0e6ts?

1) What is the difference etween /lustered 0ales and Pooled 0ales?

A !ooled tale is used to comine several lo"ical tales in the ABAP9% dictionary, Pooledtales are lo"ical tales that must e assi"ned to a tale !ool when they are defined,

/luster tale are lo"ical tales that must e assi"ned to a tale cluster when they are

defined,

/luster tale can e used to store control data they can also used to store tem!orary dataor te6t such as documentation,

1-) What is !f7status?

Pf status is used in interactive re!ort for enhancin" the functionality, If we "o to se%1* we

can "et menus* items and different function 5eys* which we are usin" for secondary list in

interactive re!ort,

1.) Amon" 8(ove8 and 8(ove /orres!ondin"8* which is efficient one?

I "uess* ;move corres!ondin"; is very efficient then ;move; statement, Because usually we

use this stamtent for internal tale fields only,,,so if we "ive move corres!ondin", 0hose

fields only movin" to other !lace what ever you want),

1) What are the out!ut ty!e and 0codes?

2) Where we use /hain and +nd chain?

21) 3o you use select statement in loo! end loo!* how will e the !erformance? 0o

im!rove the !erformance?

22) In select7o!tions* how to "et the default values as current month first date and last

date y default?

+": 191292% and #191292%
