ABAP/4 Query can create the accompanying 3 straightforward reports: Basic List: It is the straightforward reports. Insights: Reports with measurable capabilities like Average, Percentages. Positioned Lists: For scientific reports. - For making an ABAP/4 Query, developer needs to make client bunch and a practical gathering. Utilitarian gathering can be made utilizing regardless of legitimate information base table. At last, appoint client gathering to practical gathering. At last, make a question on the practical gathering created.

Q14. What is the distinction among large scale and subroutine?

Ans: Macros must be utilized in the program the are characterized in and solely after the definition are extended at assemblage/age. Subroutines (FORM) can be called from both the program the are characterized in and different projects . A MACRO is pretty much a condensing for certain lines of code that are utilized at least a time or two or two times. A FORM is a neighborhood subroutine (which can be called outer). A FUNCTION is (pretty much) a subroutine that is called outside. Since troubleshooting a MACRO isn't exactly imaginable, forestall the utilization of them (I've never utilized them, however seen them in real life). On the off chance that the subroutine is utilized just nearby (called interior) utilize a FORM. In the event that the subroutine is called outer (utilized by more than one program) utilize a FUNCTION.

Q15. What is BDC programming?

Ans: Transferring of enormous/outer/heritage information into SAP framework utilizing Batch Input programming.

Ans: What are the benefits of ITS?- ITS is an Internet Transaction Server. ITS structures a point of interaction between HTTP server and R/3 framework, which converts screen gave information by the R/3 framework into HTML archives as well as the other way around. Benefits of ITS: A finished web exchange can be created and tried in R/3 framework. All exchange parts, including those utilized by the ITS external the R/3 framework at runtime, can be put away in the R/3 framework. The upside of programmed language handling in the R/3 framework can be used to language-subordinate HTML archives at runtime.

Q22. What are the occasions in ABAP/4 language?

Ans: Initialization, At determination screen, Start-of-choice, finish of-determination, top-of-page, end-of-page, At line-determination, At client order, At PF, Get, At New, At LAST, AT END, AT FIRST.

Q23. What is CTS and what do you are familiar it?

Ans: The Change and Transport System (CTS) is an apparatus that assists you with putting together improvement projects in the ABAP Workbench and in Customizing, and afterward transport the progressions between the SAP Systems and clients in your framework scene. This documentation furnishes you with an outline of how to oversee changes with the CTS and fundamental data on setting up your framework and client scene and settling on a vehicle procedure. Peruse and follow this documentation while arranging your improvement project.

Q24. What are consistent data sets? What are the benefits/dis-benefits of legitimate data sets?

Ans: To peruse information from a data set tables we utilize consistent data set. An intelligent information base gives read-just admittance to a gathering of related tables to an ABAP/4 program. Benefits: i)check capabilities which check that client input is finished, correct,and conceivable. ii)Meaningful information determination. iii)central approval checks for information base gets to. iv)good read admittance execution while holding the progressive not entirely set in stone by the application rationale. dis benefits: i)If you donot determine a sensible data set in the program attributes,the GET occasions won't ever happen. ii)There is no ENDGET command,so the code block related with an occasion closes with the following occasion explanation (like another GET or an END-OF-SELECTION).

Q25. What are inside tables?

Ans: Internal tables are a standard information type object which exists just during the runtime of the program. They are utilized to perform table estimations on subsets of data set tables and for re-coordinating the items in data set tables as per clients need.

Q26. What is a cluster input meeting?

Ans: BATCH INPUT SESSION is a halfway step between inside table and information base table. Information alongside the activity is put away in meeting ie information for screen fields, to which screen it is passed, program name behind it, and how next screen is handled.

Q27. Step by step instructions to transfer information utilizing CATT ?

These are the moves toward be followed to Upload information through CATT: Creation of the CATT experiment and recording the example information input. Download of the source document layout. Alteration of the source document. Transfer of the information from the source document.

Q28. How might I make a separation among reliant and free information?

Ans: Client reliant or autonomous exchange necessities incorporate client explicit or cross client objects in the change demands. Workbench objects like SAPscripts are client explicit, a few passages in tweaking are client free. In the event that you show the item list for one change demand, and for each article the item ascribes, you will track down the banner client explicit. On the off chance that one item in the errand list has this banner on, that transport will be client subordinate.

Q29. What is the differrences among design and table in information word reference in ABAP?

Ans: Structure and table both are 2/2 networks however there are numerous distinctions among table and design.

Table can store the information truly however a construction portion not store.

Table can have essential key yet a construction portion not have.

Table can have the specialized characteristic yet a construction portion not have.

structure does't contain specialized credits.

structure does't contain essential key.

structure does't stores underline data set level.

Q30. What is the distinction among gather and aggregate?

Ans:

Total

While handling an inward table in a block beginning with LOOP and closed by ENDLOOP , SUM computes the control aggregates of all fields of type I , F and P (see likewise ABAP/4 number sorts ) and places them in the know yield region (header line of the inner table or an expressly determined workspace).

At the point when you use SUM in a LOOP with an expressly determined yield region, this result region should be viable with the line kind of the inside table.When utilizing LOOP to handle an arranged concentrate (see SORT ), the control complete of f toward the finish of the gathering shows up in the field SUM(f) - - on the off chance that f is type I , F or P .

Gather

Gather is utilized to make interesting or compacted datsets. The key fields are the default key fields of the inner table itab .

Assuming you utilize simply COLLECT to fill an inner table, COLLECT ensures that the interior table doesn't contain two passages with a similar default key fields.

If, other than its default key fields, the inside table contains number fields,the items in these number fields are added together assuming the inner table as of now contains a section with similar key fields.

On the off chance that the default key of an inner table handled with COLLECT is clear, every one of the qualities are accumulated in the primary table line.

In the event that you determine wa INTO , the passage to be handled is taken from the unequivocally determined workspace wa . If not, it comes from the header line of the interior table itab .

After COLLECT , the framework field SY-TABIX contains the list of the - existing or new - table passage with default key fields which match those of the section to be handled.

Gather can make exceptional or packed datasets and ought to be utilized unequivocally for this reason. In the event that uniqueness or pressure are irrelevant, or two qualities with indistinguishable default key field values could never happen in your specific undertaking, you ought to utilize APPEND all things considered. Notwithstanding, for a novel or packed dataset which is likewise productive, COLLECT is the assertion to utilize.

On the off chance that you cycle a table with COLLECT , you ought to likewise utilize COLLECT to fill it. Simply by doing this might you at any point ensure that the inward table will really be novel or packed, as portrayed above and COLLECT will run effectively.

Assuming you utilize COLLECT with an unequivocally indicated workspace, it should be viable with the line sort of the interior table.

Q31. Make sense of the program stream when we utilize coherent information base PNP or PNPCE?

Ans: If you utilize any of the LDBs, the program stream is as beneath

Report XXXXXX.

Information statement

START_OF_SELECTION.

GET PERNR.

recover the information from interior tables to yield inner tables

END_OF_SELECTION.

Show the information recovered previously.

From GET PERNR to END_OF_SELECTION ; it will circle with the representative numbers chose from the determination screen.
