As per my experience ,practice makes you perfect ,as a technical consultant ,should be ready to develop any object based on the need of client ,then only ,we will get appreciation from client and from our team side and it helps us to develop complex objects in SAP.

April 12, What is ALV? What are the uses of ALV reports? Like on Facebook.Boris Rubarth. If, for example, you want to get a list of users from the target system, your coding may look as shown in Listing 2. Was that all we need to know about BAPIs? Of course not … and again this introductory coding is not sufficient, so let us dig deeper. So why are you reading this chapter? BAPIs offer some very important and helpful features for your remote communication but also hold some traps—so it is worth examining some of the details.

Nevertheless, if the RFM is the implementation, there must be something beyond the implementation, some meta level that the RFM is implementing. Later on, we will discuss a smarter way to search for BAPIs. The next part of the name is the object to which the BAPI is related. This object is a representation of business data to which the BAPI shall offer an interface. Figure 2. This book introduces readers to all relevant classic technologies for system-to-system communication using ABAP, including synchronous and asynchronous techniques.

It is the process of calling a function module which is residing on a different machine from the caller program. It is SAP Specific protocol. This means that an RFC connection you have defined in client can also be used from client without any difference. RFC is the protocol for calling special subroutines function modules over the network.

They have a defined interface through which data, tables and return codes can be exchanged. The Function Builder transaction SE37 provides application programmers with a useful environment for programming, documenting and Testing function modules that can be called locally as well as remotely.

The only difference between a remote call of a function module to another server and a local call is a special parameter destination that specifies the target server on which the program is to be executed.

The RFC Advantages: RFC helps to reduce the efforts of programmers, by letting them avoid the re-development of modules and methods at remote systems. It is capable enough to: Convert the data into the format understandable by the remote target system.

Convert the data into the format understandable by the remote target system. Call up certain routines which are necessary to start communication with the remote system.

Handle errors that might occur in the process of communication. Types of RFC: Synchronous Requires both the systems client and server to be available at the time of communication or data transfer. It is the most common type and is required when the result is required immediately after the execution of sRFC. The Data is consistent and reliable for communication. The issue is if the target system is not available, the source system resources wait until target system is available.

It doesn't require both the systems to be available at the time of execution and the result is not immediately required to be sent back to the calling system.

It is not reliable for communication since data may be lost if the target system is not available. Transactional RFC ensures transaction-like handling of processing steps that were originally autonomous. Transactional RFC is an asynchronous communication method that executes the called function module in the RFC server only once, even if the data is sent multiple times due to some network issue.

It also ensures that individual steps are processed in sequence. Used For- Extension of the Transactional RFC For a defined processing sequence Implementation of qRFC is recommended if you want to guarantee that several transactions are processed in a predefined order.

You can, however, specify logon information if desired. These entries are pre-defined and cannot be modified. The activation type can be either Start or Registration. If it is Startyou must specify the host name and the pathname of the program to be started. How to Code an RFC? In the function module attributes tab transaction code SE37set the processing type as Remote-enabled module to create a remote function module.

Write the code for the function module. Declaring Parameters : All parameter fields for a remote function module must be defined as reference fields, that is, like ABAP Dictionary fields. You can raise exceptions in a remote function just as you would in a locally called function.

Debugging Remote Function Calls It is not possible to debug a remote function call to another system. With remote calls, the ABAP debugger including the debugging interface runs on the local system.

Data values and other run information for the remote function are passed in from the remote system. It helps convert What is SAP Data services? Home Testing. Must Learn!Need to change your career to Sap Bapi?

What Are Rfc Interfaces? Question 7. Question 8. Answer : Converting all parameter data to the representation needed in the remote system Calling the communication routines needed to talk to the remote system. Convert the data into the format understandable by the remote target system. Call up certain routines which are necessary to start communication with the remote system.

Handle errors that might occur in the process of communication. Question 9. Answer : Support of synchronous and asynchronous communication. Support of machine-to-machine and human-to-machine communication. Communication support for components that are narrowly linked and coupled through the Internet. Question Answer : A business object type is the representation of a business object, like an human work force or a Invoice, in an SAP System.

It encompasses both the functions and the data into single object. Answer : We can reduce the complexity of Systems structure by dividing the complex structures into smaller units. Arranging the various business object types according to the component hierarchy.

BAPIs which could create, trade or delete times of a commercial enterprise object type.

The following BAPIs of the equal object type must be programmed so that they can be called several times within one transaction. For example, if, after income order 1 has been created, a 2nd sales order 2 is created inside the same transaction, the second one BAPI name ought to not affect the consistency of the sales order 2. The instance to be cancelled stays in the database and an extra instance is created and that is the only that is sincerely canceled.

These BAPIs are class techniques. These BAPIs are example strategies. In this example u best specify the commercial enterprise item and its approach from external gadget in BAPI there is no direct machine name. These BAPIs need to be applied the equal for all business object sorts. A remote function call is a call to a function module running in a system different from the caller's.

To familiar with coding and ABAP applications ,you must be practice all applications.These BAPIs should be implemented the same for all business object types.

The instance is identified via its key. BAPIs that can create, change or delete instances of a business object type The following BAPIs of the same object type have to be programmed so that they can be called several times within one transaction.

For example, if, after sales order 1 has been created, a second sales order 2 is created in the same transaction, the second BAPI call must not affect the consistency of the sales order 2.

Create and CreateFromData! These BAPIs are class methods. These BAPIs are instance methods. The instance to be cancelled remains in the database and an additional instance is created and this is the one that is actually canceled. Bapi Function Modules can be attached to these Bapi objects. The data from several different tables can be stored together in a table pool or table cluster. Tables assigned to a table pool or table cluster are referred to as pooled tables or cluster tables.

A table in the database in which all records from the pooled tables assigned to the table pool are stored corresponds to a table pool. The definition of a pool consists essentially of two key fields Tabname and Varkey and a long argument field Vardata.

A cluster key consists of a series of freely definable key fields and a field Pageno for distinguishing continuation records. A cluster also contains a long field Vardata that contains the contents of the data fields of the cluster tables for this key. If the data does not fit into the long field, continuation records are created.

Control information on the structure of the data string is still written at the beginning of the Vardata field. You cannot access a hashed table using its index.

The response time for key access remains constant, regardless of the number of table entries. Like database tables, hashed tables always have a unique key. Hashed tables are useful if you want to construct and use an internal table which resembles a database table or for processing large amounts of data.

Sample Prog: This does nothing. In this case you only specify the business object and its method from external system in BAPI there is no direct system call. RFC is the protocol used by SAP for remote communication, that is, for communications between remote independent systems.

Difference between RFC and BAPI

It can also be used for communications between modules on the same system. What is the different btween clear and refresh? Refresh will deletes the Internal Table content but still memory is not freed. What is the pick statment do? Pick Statemnt will captures the UserAction. What is the different between sesstion method and call transaction method and suppose I used one method to transform the data next time suppose I want transform the data which method I can use.

There are many difference between Session method and Call Transaction. Mainly Call Transaction used for small sets of data because in Call Transaction we have to Handle the Processing errors explicitly.

In Session method seperate session will crate for errors. Calll Transaction will update the Database fastly compare with Session Method. What is single and upto one row different? Select Single will search for all the satisfied data and bring all that data into Buffer and later it will give to that data to the program.

Select UPTO 1 Rows will end the search after getting the 1st satisfied record and gives that record to the program. What is the differences between selection screen and selection screen out?
