There are two different buffering methods What are the different buffering methods? whereas select up to 1 rows will fetch all the matching recordsġ8. If more than one matching records are there then only the first matching record will be considered other records will not be taken into account. Select single fetches first matching record. Select up to 1 row and select single difference ? it improves performance 10 to 100 times moreġ7. Explain about the tables exists in a data dictionary and what are they?Īnswer: There are four tables that exists in a data dictionary, they areīuffering is use for improve performance. It should always be a HEADER field group that defines how the extracted data will be sorted the fields grouped under the HEADER field group sort the data.Īnswer: The events in ABAP/4 are load of program ,Initialization, Selection Screen, Start of Selection, End of Selection, Top of page, Line selection, User command, End, First.ġ5. What is the difference between scrolling a table horizontally and vertically.?Īnswer: In table control when you scroll a table vertically presentation server needs to call application server to fetch the next record and display in the table while in case of horizontal scroll there is no need to call application server.Īnswer: A group that combines several fields fewer than one name, at runtime, the INSERT command is used to define which data fields are assigned to which field group are called Field Groups. Īnswer: page window is nothing but a container of a page ,which uniquely identifies a set of data …for example while creating invoice …we create logo window, billing document header window, customer window, terms and condition window etc …ġ2. with this Tcode u create RFC(remote function call) to create communication link to a remote system.Īnswer: occur statement allocates 8kb of memory to the internal table …but generally we dont use it because of performance issue …if we don’t use occur then the internal table will act as a structure. now open the print program in se 38 …u vll notice that the print prgm is automatically diverted to debugging mode.Īnswer: This concept is mainly used in IDOC where u select the partner profile using Tcode SM59. a message will show that debugger is activated. then goto SE38 execute the print program ,it automatically goes to debugging mode ….the other way is, run the program RSTXDBUG in se 38. first way is goto SE 71 and from menu bar select Utilities->activate debugger. Use binary search but before using binary search sort that table.Īnswer: Two ways to debug sapscript. Use select single * statement instead of select *ħ. Use st05 SQL trace, se30 run time analysis, code inspector, slin,etc.ĥ. Never write select statements inside loop….endloop.Ĥ. During writing select query write all fields in sequence as per database table.ģ. The sequence of fields must be same as per database tableĢ. The same append structure cannot be appended in more than one standard tableġ. append?ġ)The include statement is used to add structure to the custom table and append statement is used to add structure to the standard table.Ģ) The same structure can be included in more than one custom table. LSMW is also used when the person like functional consultant has less programming language.ĥ. When we need to update medium amount of data we use LSMW. For small or less amount of data and for single transaction use call transaction.Ī. If we want to transfer large amount of data and when we need to use more than one transaction code we prefer session method. Yes it is possible to write call transaction and session in one program.Ī. Can we write the code both call transaction and session method in single program?Ī. Finally, i come up with the following questions which are mostly asked in all the Big companies including SAP Labs, Accenture, IBM, Deloitte, TCS, Infosys etc…ġ.
