Understanding the Role of BDC in SAP ABAP: A Comprehensive Overview

What Is Bdc In Sap Abap

BDC in SAP ABAP is a crucial concept that plays a significant role in automating data entry tasks. This article will provide an overview of BDC and its importance within the SAP ABAP environment. We will explore how BDC allows for the creation, modification, and deletion of large volumes of data by simulating user interactions with transaction screens. Additionally, we will discuss the different methods available for implementing BDC and highlight key considerations when using this functionality in SAP ABAP development projects.

Batch Input Methods in SAP ABAP

SAP offers two primary approaches for importing historical data into the R/3 System.

1. The traditional approach for batch input in SAP ABAP is known as the Classical Batch Input method.

2. Another method used for batch input in SAP ABAP is called the Call Transaction Method.

In this method an ABAP/4 program reads the external data to the SAP System and stores in a batch input session.

Once the session has been created, it can be executed to carry out the SAP transaction within it.

The BDC method employs the function modules BDC_OPEN, BDC_INSERT, and BDC_CLOSE to accomplish its tasks.

  1. In the foreground
  2. In the background
  3. During processing, with error display

You should process batch input sessions in the foreground or using the error display if you want to test the data transfer.

To perform the data transfer or assess its efficiency, it is advisable to carry out the session processing in the background.

– Synchronous execution

– Transmit information for several transactions.

– Real-time database update.

– A log is created for each batch input session.

– Sessions cannot be generated simultaneously.

In this approach, the ABAP /4 program utilizes the CALL TRANSACTION USING statement to execute an SAP transaction.

The entire process of batch input occurs in real-time within the program.

– Speeds up data processing

– Allows for asynchronous processing

– Enables the transfer of data for individual transactions

– Does not generate a log for batch input processing

Batch Input Procedures

The usual process for creating Batch Input in your company usually involves the following steps.

  1. Analysis of the legacy data. Determine how the data to be transferred is to be mapped in to the SAP Structure. Also take note of necessary data type or data length conversions.
  2. Generate SAP data structures for using in export programs.
  3. Export the data in to a sequential file. Note that character format is required by predefined SAP batch input programs.
  4. If the SAP supplied BDC programs are not used, code your own batch input program. Choose an appropriate batch input method according to the situation.
  5. Process the data and add it to the SAP System.
  6. Analyze the process log. For the CALL TRANSACTION method, where no proper log is created, use the messages collected by your program.
  7. From the results of the process analysis, correct and reprocess the erroneous data.

The Purpose of BDC in SAP

BDC Sessions are commonly employed for two purposes: loading SAP systems with legacy data and automating repetitive data entry tasks. These sessions mimic the process of entering transactions and data online, including all the validations associated with each transaction.

1. Loading SAP systems with legacy data.

2. Automating repetitive data entry tasks.

3. Simulating online entry of transactions and data.

4. Incorporating all validations within each transaction.

BDC Program Writing in SAP ABAP

To create your BDC program, you can follow the steps outlined below.

  1. Analyze the transaction(s) to process batch input data.
  2. Decide on the batch input method to use.
  3. Read data from a sequential file
  4. Perform data conversion or error checking.
  5. Storing the data in the batch input structure,BDCDATA.
  6. Generate a batch input session for classical batch input,or process the data directly with CALL TRANSACTION USING statement.


Field name Type Length Description
The PROGRAM field is of type CHAR and has a length of 8 characters. It represents the module pool.
The DYNPRO field is of type NUMC and has a length of 4 characters. It stores the dynpro number.
The DYNBEGIN field is of type CHAR and has a length of 1 character. It indicates the start of a dynpro.
The FNAM field is of type CHAR and has a length of 35 characters. It represents the name of the field.
The FVAL field is o

The arrangement of fields in the data for a specific screen does not hold any importance.

To ensure proper alignment, condense the FVAL field for amount and quantity fields so that they are left-aligned.

It is crucial to treat all fields populated through BDC as character type fields when populating the BDC Data table.

In certain screens where values need to be populated in a table control using BDC, it is necessary to determine how many rows are present by default and code accordingly. If additional rows need to be populated beyond what appears initially on the screen, “Page down” functionality should be implemented similar to manual population of the table control.

What is the objective of BDC?

Furthermore, BDC recognizes the importance of knowledge sharing among entrepreneurs. They organize workshops and networking events where experienced professionals share their insights with aspiring business owners. These platforms not only facilitate learning but also encourage collaboration between like-minded individuals who may potentially form partnerships or mentorship relationships.

Overall, by supporting Canadian entrepreneurs financially while promoting knowledge exchange and inclusivity within the entrepreneurial community,BDC plays an instrumental role in building strong businesses across Canada that contribute towards its overall prosperity,c ompetitiveness,and inclusiveness

Batch Input Session Creation in SAP ABAP

To initiate the batch input session, you can utilize the BDC_OPEN_GROUP function module. Within this session, each transaction should be processed individually. It is necessary to populate the BDCDATA structure with appropriate values for all screens and fields involved in each transaction. Once a transaction is prepared, it can be transferred to the session using BDC_INSERT. Finally, when all transactions have been processed, you must close the batch input session by calling BDC_CLOSE_GROUP.

What is the number of BDC types available?

1. Session Method: A primary approach in the SAP system for transferring data from non-SAP systems.

2. Call Transaction Method: Another primary technique used in the SAP system for importing data from non-SAP systems.

What is BDC in SAP ABAP

The BDC (Batch Data Communication) in SAP ABAP is a feature that allows users to record manual transactions and generate a batch input session for future execution through the SM35 transaction.

Is BDC applicable in OData?

In simple terms, BDC in SAP ABAP refers to a mechanism that enables seamless integration of data from external systems into an SAP system. It acts as a bridge between different applications, allowing them to communicate and exchange information effectively.

– BDC in SAP ABAP facilitates seamless integration of data from external systems into an SAP environment.

– It acts as a bridge between different applications by defining mappings and connections.

– Developers can use prebuilt models and tools provided by SAP to simplify the integration process.

Types of BDC and their definition

Batch Data Communication (BDC) is a powerful tool used in SAP ABAP programming for uploading or updating data in large quantities into SAP system. With the help of BDC, we can easily automate the process of data input and data update, saving time and increasing efficiency.

BDC control: Who has it?

BDC, or Botswana Development Corporation, is a government-owned company in Botswana. It operates as a Limited by Shares entity and is governed by an independent Board of Directors. The Board is headed by an Independent Non-Executive Chairman who oversees the control of the corporation. The day-to-day operations of BDC are managed by the Managing Director.

Starting a BDC: Where do I begin?

To conduct market research and determine the focus of your BDC, you should consider the following steps:

1. Choose a legal entity type: Once you have identified your focus, it is important to establish a legal entity for your BDC.

2. Acquire professional certifications: Obtain relevant certifications that will enhance your credibility and expertise in the chosen field.

3. Obtain and submit legal documents: Gather all necessary legal documents required for establishing and operating your BDC.

4. File with the Securities and Exchange Commission (SEC): Complete the necessary filing procedures with the SEC to ensure compliance with regulatory requirements.
