BDC & BAPI

[Former Member]

Hi All,

What is main difference between BDC & BAPI.

Now a days all are using BAPI.

1.use to write code by using BAPI.

2.No Screen Flow.

3.No TC probs.

Difference between BAPI and BDC:

BAPI is a higher end usage for tranfering the data from SAP to non-SAP and vice-versa. for ex: if we are using VB application,where in that we want to connect to SAP and retireve the data,and then change and update the data in SAP for that purpose we can use that.

Apart from that, we can also use it for Uploading/Downloading the data from SAP to Non-SAP like BDC, provided we have an existing BAPI for that.

BAPI function modules will also do all the checks required for data integrity like Transactions for BDC.

There is one more advantage using BAPI instead of BDC. When we go for upgradation, there might be pozzibility to change the screen elements for transactions depending on the requirement. In that case,our BDC pgm may or may not work (depending on the screen changes they have made). Unless and until we prepare new BDC we cant use the old BDC pgm. But in BAPI, SAP promises that they are going to keep the old BAPI and for new functionality they will provide an upgraded BAPI. Until we write a new BAPI pgm, we can use the exisitng BAPI pgm.

1. Batch Data Communication or BDC is a batch interfacing technique that SAP developed. It is mainly used for uploading data into the SAP R/3 system. BDC works by simulating the user input from transactional screen via an ABAP program.

The data input data file will come in the form of a flat file which the user save as file type txt file or prn file from the Microsoft Excel program. An Abaper will create a program to read the text file and upload into the SAP system.

Normally, the tcode SHDB will be used to record the transaction code the user used. After, the simulation, the Abaper can generate a sample program and modify from there. It makes the programming easier and faster.

SAP created the Business Framework to allow the technical integration and exchange of business data among SAP components and between SAP and non-SAP components. Important components of the Business Framework are the Business Application Programming Interfaces (BAPIs), which represent visible interfaces at the component boundaries and whose properties serve to integrate these components.

The integration can include both components within a local network and components that are connected with one another through the Internet.

BAPIs allow integration at the business level, not the technical level. This provides for greater stability in the link, and independence from the underlying communication technology.

You can get all the standard SAP BAPI functions with the transactions code 'BAPI'.

hi,

Advantages of BAPI

1. Simple to use (its just an FM)

2. Not cumbersome like bdc

where we have to record each and every screen

sequence.

3. SAP guarantees the consistency

of bapi in future releases.

*Reward points if helpful

BAPI is used only when it is available for the particular transaction like Delivery Sales order. but BDC can be used for any

transaction which have screen and fields.

BAPI is directly updated the database instead BDC run through the screen flow.

So BAPI can't handle all the flow logic checking and enhancement put by programmer to faciliate the user requirement.

BAPI is a higher end usage for tranfering the data from SAP to non-SAP and vice-versa. for ex: if we are using VB application,where in that we want to connect to SAP and retireve the data,and then change and update the data in SAP for that purpose we can use that.
