ABAP Interview questions

ans.  Smart Forms allows you to create forms using a graphical design tool with robust functionality, color, and more. Additionally, all new forms developed at SAP will be created with the new Smart Form solution.

Q. How can I make a differentiation between dependent and independent data?-

ans. Client dependent or independent transfer reQuirements include client specific or cross client objects in the change reQuests. Workbench objects like SAPscripts are client specific, some entries in customizing are client independent. If you display the object list for one change reQuest, and then for each object the object attributes, you will find the flag client specific. If one object in the task list has this flag on, then that transport will be client dependent.

Q. What is the difference between macro and subroutine?

ans.  Macros can only be used in the program the are defined in and only after the definition are expanded at compilation / generation. Subroutines (FORM) can be called from both the program the are defined in and other programs . A MACRO is more or less an abbreviation for some lines of code that are used more than once or twice. A FORM is a local subroutine (which can be called external). A FUNCTION is (more or less) a subroutine that is called external. Since debugging a MACRO is not really possible, prevent the use of them (I’ve never used them, but seen them in action). If the subroutine is used only local (called internal) use a FORM. If the subroutine is called external (used by more than one program) use a FUNCTION.

Q.  What are client dependant objects in abap/sap? 
 ans. SAP Script layout, text element, and some DDIC objects. 

Q. On which even we can validate the input fields in module progams? 
ans. In PAI (Write field statement on field you want to validate, if you want to validate group of fields put in chain and End chain statement.) 

Q. In selection screen I have three fields, plant mat no and material group. If I input plant how do I get the mat no and material group based on plant dynamically? 

ans. AT SELECTION-SCREEN ON VALUE-REQUEST FOR MATERIAL. 
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST' to get material and material group for the plant. 

Q. How do you get output from IDOC? 
ans. Data in IDOc is stored in segments, the output from Idoc is obtained by reading the data stored in its respective segments. 

Q.  When top of the page event is triggered? 
ans. After excuteing first write statement in start-of-selection event. 

Q.  Can we create field without data element and how? 
ans. In SE11 one option is available above the fields strip. Data element/ direct type. 

Q.  How do we debug sapscript? 
ans. Go to SE71 give lay set name , go to utilities select debugger mode on.

Q.  Which transaction code can I used to analyze the performance of ABAP program. 
ans. TCode AL21.

Q.  How can I copy a standard table to make my own z_table.
ans. Go to transaction SE11. Then there is one option to copy table. Press that button.  Enter the name of the standard table and in the Target table enter Z table name and press enter.
