13 What is the difference between BDC Session and call transaction?

BDC Session is a two step process. You create a session first and then process the session later. Process using SM35 or by calling RSBDCSUB program.

CALL Transaction is instant.

14 What is the criteria for selecting one of these above methods?

If you do not need to process the data right away and You do not need to report back immediately then you choose BDC.

If you need to report the result back then use CALL Transaction. If you have further processing of that data then you need that. For example, You need to create a sales order and Once it is processed you need to update the status of that in another table with Order number.

15 How do you change session method from foreground to back ground.

In SM35 you can process the session in Foreground or Background mode.

You can switch to Background mode using Menu path System à Services à Display Errors Only Or Expert Mode on

/BEND to End Batch Input Session

VTTK, VTTP, VTTS Shipment Tables

MKPF, MSEG

VBUK - Document Status

VBUP - Document Line item status

VBFA - Document Flow (It links Sales orders and Deliveries)

VBFS - Error Log in Collective processing

21 Why do we use CHAIN and ENDCHAIN?

These statements starts a processing chain. If you send a warning or error message from a module that you called using a FIELD statement as follows:

CHAIN.

FIELD: , ,...

MODULE .

FIELD: , ,...

MODULE .

...

ENDCHAIN.

all of the fields on the screen that belong to the processing chain (all of the fields listed in the field statements) are made ready for input again. Other fields are not ready for input. Whenever the MODULE statement appears within a processing chain, even if there is only one FIELD attached to it, all of the fields in the chain (not only the affected field) are made ready for input again, allowing the user to enter new values. If the fields in the processing chain are only checked once, the PAI processing continues directly after the FIELD statement, and the preceding modules are not called again.

AT LINE-SELECTION event.

38 What is the diffrence between client dependent and independent tables?

If you have MANDT as the first field that is Client Dependant table otherwise it is not. Usually most of the tables are client dependent. Only few like RFC Connections table (RFCDES), Batch Jobs (TBTCO and TBTCP) are not client dependant.

39 What are the events in interactive reports?

AT LINE-SELECTION, AT PF-KEY, AT USER-COMMAND .

40 What is the difference between at selection screen and at selection screen output?

AT SELECTION-SCREEN OUTPUT is like Process Before Output Event. This would get triggered before screen is displayed. This can be used to make fields invisible/visible based on selection.

AT SELECTION-SCREEN: This would be triggered if you hit any thing (Enter, Drop-Down, Help, Execute) after the selection screen is displayed.

41 Which one will be trigger first?

AT SELECTION-SCREEN OUTPUT

42 What is the difference between clear, refresh

CLEAR: It clears any field, structure or Header line of Internal table

51 Why are you not using the OOPS concept in ALV’s?

52 In ALV’s how would you get default values in the selection screen?

Create a variant in the ALV Report with what ever columns you would like to see and set sort criteria and column widths and save as a default variant.

You can set it using Settings à Layout à Layout Management and make sure DS is set for the variant.

You could get the default variant by calling FM REUSE_ALV_VARIANT_DEFAULT_GET

53 How would u handle table controls in BDC?

Record in Table Controls are referred by Index. If it is the first line MARA-MATNR is the field, you use MARA-MATNR(01).

To point to the correct line there are Position Buttons on these screens. Using that button you position that line as the first line and update the first line.

54 Advantages of call transaction over session method?

v Call Transaction is instant update

v Result is known immediately

v Error message can be shown to the user.

v If program is being run online, we can provide an opportunity to correct the data if needed.

55 How would you handle the script?

56 If u want to add any fields in the layout what is the procedure you follow?

57 Difference between Synchronous and asynchronous update?

v Synchronous update is Update immediately and the program waits for the work process to finish the update.

v Asynchronous update could be delayed and the program does not wait for the work process to finish the update.

58 How to print page numbers in a script through SE38 Program?

59 What are the steps to create custom table?

v Make sure you select the Primary Key for this table.

v Maintain the Technical Settings (Data class, Size, Buffering info)

v Create Secondary indexes as needed

v Activate the Table

60 What are the functional modules are used in ALV reports?

61 If the table contains built in type what is the problem?

If a field contains Built-In Type, in SE16 field header is not shown, Search help or Dropdowns are not shown automatically.

62 How to print a text which in English in different languages what are the steps to be taken?

To Print a Text, you would have to use Text Elements in Reports. You need to Login in different languages and maintain Texts in each language. Based on the login language, these texts are automatically printed in various languages.

63 How to capture messages in call transaction?

CALL TRANSACTION 'TFCA' USING BDCDATA

MODE 'A'

UPDATE 'S'.

MESSAGES INTO MESSTAB.

64 Without using BDCMSGCOLL How can u find out, weather the record is successfully updated or not?

SY-SUBRC would tell whether CALL Transaction was successful or not. If SY-SUBRC is not equal to zero that means Transaction failed. Reason would stored in messages table.

65 What is client dependent and independent?

If you have MANDT as the first field that is Client Dependant table otherwise it is not.

66 What is client dependent and independent tables? Differences between them?

If you have MANDT as the first field that is Client Dependant table otherwise it is not. Usually most of the tables are client dependent. Only few like RFC Connections table (RFCDES), Batch Jobs (TBTCO and TBTCP) are not client dependant.

If you select an entry from Client dependant table, it checks with in that client unless you specify SELECT statement using Client Defined.

Ex: SELECT * FROM SCUSTOM CLIENT SPECIFIED INTO WA_SCUSTOM

WHERE MANDT = '003'.

WRITE: / WA_SCUSTOM-ID, WA_SCUSTOM-NAME.

ENDSELECT.

67 How to set hotspot in ALV reports for a field?

In the Field Catalog table, you set the HOTSPOT property of the field to X

68 How to set hotspot in ALV reports for all fields?

69 What is use of REUSE_ALV_FIELDCATALOG_MERGE?

Using this function module, you can get the Field catalog for a given Internal table or DD Structure. Once you get the Field catalog, you could change the properties of each field.

70 What is significance of HIDE?

In Interactive reports, HIDE statement stores the value of that field for that line. If the user places the cursor on a line and click on some thing those values are automatically populated to that hidden fields. These values are used to drill down further or takes to other transaction using this info.

71 What is local update?

When you do CALL TRANSACTION, you could select a Local Update. Local updates means update happens on the same Apserver you logged on using the same work process.

In a local update, the update program is run by the same work process that processed the request. The dialog user has to wait for the update to finish before entering further data. This kind of update is useful when you want to reduce the amount of access to the database. The disadvantage of local updates is their parallel nature. The updates can be processed by many different work processes.

72 Difference between select single and select upto one row?

SELECT SINGLE can be used if you know the full key to select a record. If you do not have the full Key to select and you are interested in one single row, you could use SELECT UPTO 1 ROWS. If you use a SELECT SINGLE with out a full key, you would get a warning message in Extended Program checks.

73 Between select single and select upto one row, which method do u prefer at which situation?

If you have the full Key use SELECT SINGLE

If you do not have the full Key to select and you are interested in one single row, you could use SELECT UPTO 1 ROWS..

74 What is the secondary index?

There is an Index created by default for the Primary Key of the table and that is called Primary Index. If you create, any other index that is called Secondary Index for that table. Secondary Indexes are created to improve the performance of SELECT statements.

75 How to create secondary index?

Using SE11, Enter the table name and click on Change.

Click on Indexes and select fields and create a secondary index. Note: Always try to include MANDT as the first field unless you have a reason..

76 How to change standard data base table?

77 How do you modify a table?

You can modify a record using MODIFY statement or UPDATE Statement .

78 Events in the report and the order in which they trigger?

AT SELECTION-SCREEN OUTPUT

AT SELECTION-SCREEN

AT SELECTION-SCREEN ON HELP-REQUEST

AT SELECTION-SCREEN ON VALUE-REQUEST

START-OF-SELECTION

END-OF-SELECTION

TOP-OF-PAGE

TOP-OF-PAGE DURING LINE SELECTION

79 Events in Module pool and comparison with report events?

PBO – Process Before Output AT SELECTION-SCREEN OUTPUT

PAI – Process After Input AT SELECTION-SCREEN

PROCESS ON HELP REQUEST AT SELECTION-SCREEN ON HELP-REQUEST

PROCESS ON VALUE REQUEST AT SELECTION-SCREEN ON VALUE-REQUEST

80 Difference between scripts and smartforms?

81 Advantages of smartforms overscripts?

82 How do you INVOKE scripts from a program?

Using Function module OPEN_FORM, WRITE_FORM and CLOSE_FORM.

83 How do you INVOKE Smartforms from a program ?

There is a Function module behind every Smart Form. You call the function module to invoke it from a Program.

84 What Happens after a smartform is triggered?

85 What are enhancements and its procedure?

Enhancements are changes to existing SAP objects. Using CMOD, you can check what enhancements are available.

v You create a Project using CMOD

v select an Enhancement that you need to modify.

v Modify and add the code in that enhancement

v Activate the Project.

86 Difference between enhancements and modifications?

Enhancements are changes to existing SAP objects. Using CMOD, you can check what enhancements are available and modify it. If the Enhancement is not available but you can not achieve the goal with out modifying the actual SAP code, you go ahead and modify the SAP code. That is modification. Modifications are discouraged by SAP because these are little bit difficult to handle during upgrades.

87 How do you create an interactive ALV Report?

Need to pass, parameter I_CALLBACK_PF_STATUS_SET = G_ALVPFSTATUS (FORM Name) so that you can set your own status using SET PF-STATUS command.

Need to pass, I_CALLBACK_USER_COMMAND = G_ALVCOMMAND (FORM name) , so that you can write code to process the user command.

88 What is an ABAP Memory and SAP Memory and How to use them?

ABAP memory is a memory area that all ABAP programs within the same internal session can access using the EXPORT and IMPORT statements.

SAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set either for a particular user or for a particular program using the SET PARAMETER statement. Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on screens (see below).

89 Are labels possible in Smartforms?

90 Configurations in ALE IDOC.
