Difference between ALE message distribution using BAPIS and Message Types

[Former Member]

Hello guys,

could someone explain what is the difference between the message distribution using BAPIS and using Message Types in ALE scenarios?

In the "maintain distribution model" view there are buttons to add BAPIS and to add Message types. I made a test model and to the same model I added both and worked. You always have to use both to work?

I added message type CREMAS and BAPI Vendor.Create. Is this right or not?

Any help would be appreciated

HI,

To implement the distribution of business application processes and functions using ALE you need to construct a logical Distribution Model of the whole system. Within the framework of this configuration, customers can specify which applications are to run on which systems and which messages are to be exchanged between the applications

The distribution model describes the ALE message flows between logical systems

You can specify the relationships between logical systems, message types, BAPIs and filters in the distribution model. Applications and the ALE layer use the model to determine receivers and to control the data distribution

The distribution model consists of one or more views that you can define. With more complex distribution tasks you can assign business sub-areas or groups of logical systems to separate views.

The relevant views of the distribution model must be available in all the logical systems involved in ALE. You can find the functions for distributing views in Customizing for ALE

The exact diff is with Message type yu can have the sender,receiver and message type (structure) to distribute the task but with sub-areas or groups you can use BAPIs , here yu would have the object name/ interface name and the method to implement.
