Difference between ALE vs BAPI.? ›

The BAPI call is synchronous, i.e. you expect an immediate response from the remote system. The BAPI call will fail if the remote system is not available. In contrast, the IDoc

the difference between RFc and BAPI are business objects. which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA. in BAPI there is no direct system call. while RFC are direct system call.

the main difference in BAPI is it is used for Third party application like JAVA, VB etc. and IDOC is used transfer data from the SAP to sap or non-sap system. ALE is SAP proprietary technology that enables data communications between two or more SAP R/3 systems and/or R/3 and external systems.

What is ALE ? ALE stands for Application Link Enabling. Application Link Enabling is a very common technology used in SAP to transfer master and transactional data between different Logical Systems.

An IDoc interface has a defined data structure and IDoc processing logic. The SAP term for data exchange with other in-house systems is ALE (or Application Link Enabling). The term EAI stands for Enterprise Application Integration and is also commonly used in non-SAP environments.

BAPI packages multiple internal functions to enable programmatic access to such higher-order tasks as checking customer numbers, providing product descriptions, selecting products, creating quotations or creating orders.

BAPI is a SAP-supplied function module with a defined interface, which allows you to interact with various business objects. SAP guarantees the integrity of your database for anything updated using a BAPI. BDC is a method of driving screens programatically, for updating SAP data. BAPIs are generally faster than BDCs.

The BAPI call is synchronous, i.e. you expect an immediate response from the remote system. The BAPI call will fail if the remote system is not available. In contrast, the IDoc processing (ALE) will wait until the remote system is available again and then the message is delivered.

For BAPI inbound processing, you can specify that the processing be handled synchronously (in which both the client application and the adapter must be available during processing) or asynchronously (in which the adapter does not have to be available when the client application invokes the function call).

There are two types of BAPI's: Instance Dependent & Instance Independent. BAPI provides an access to the SAP system for external applications to have the business data processed in the form of web services. When BAPI's are used to post the data in SAP system these are used as Function Modules.

What is ale used for? ›

Ale, along with bread, was an important source of nutrition in the medieval world, particularly Small beer, also known as table beer or mild beer, which was highly nutritious, contained just enough alcohol to act as a preservative, and provided hydration without intoxicating effects.

Different types of ale you might find are brown ale, pale ale, India pale ale (IPA), golden ale, Scotch ale, mild ale, Burton ale, old ale, cask ale, and Belgian ale.

Application Link Enabling (ALE) enables you to exchange data within a system group. You can use ALE to send Customizing data, transaction data, and master data to other systems as IDocs. This is implemented as part of a distribution model.

IDOC is an asynchrnous communication. You can get acknowledgement. But it will not return any errors in target system.

There are basically two types of IDOCs. Basic IDOCs : Basic IDOC type defines the structure and format of the business document that is to be exchanged between two systems.

Integration of various SAP systems with use of IDoc messages is still very popular and sometimes even the backbone of the interfaces developed between SAP ABAP stack systems and 3rd party. This is very common in Logistics or Production focused organizations.

BAPI is a remote function module and it will store in BOR(business object repository). You can call BAPI from Non-SAP system also. Function module is only you can call with in the system. This not non Remote Function Call...

with normal fms u can use it within SAP system ,whereas in case of RFC Fm u can this fm from any external system e.g for eprocurement purpose etc. In case of update Fm these directly can be used like ur commit work.

Main difference: RFC is runs on the Java engine and Proxy is an adapter less communication where both sender and receiver are on webASS 6.4+.
