Definition of the distribution model and data filtering
We have already seen that the distribution model is used to decide who sends what to who. But, as you guessed, there is a little bit more to be said about it and the way to manage it.
The distribution model is maintained in a central transaction (BD64) which lets you access the most useful environmental settings necessary to set up the model. Before creating the model, you must first decide on which system you are going to create it. Indeed the model must exist in all partners systems and two possibilities exist to achieve this.
Either you create the model on each system manually (with the same model technical name), which is feasible only with few systems and/or simple models. Either you create it in a specific system (usually the source system) and distribute it to the other systems thanks to the distribution command in the BD64 transaction menu.
If we want to copy the customers master data from the production system to the other systems in the maintenance line for example, we may create the distribution model on the production system and distribute it to all partners systems.
The actual creation of the model requests that you mention a technical name for the model (unique identifier in the systems landscape), a sender system, a receiver system and message types to exchange between those systems. You may afterwards add more sending and receiving systems in the model as well as more message types.
For each message type defined between a sender and a receiver, you may set filters on specific fields of the message type so that IDocs be generated only when these specific values are matched. For example, you may decide to send only customers of a specific account group. These filters are set by selecting the 'no filter set' text under message types in BD64.
There exists also another kind of filters which are segments filters. They do not filter IDocs creation based on values like we have just seen but filter unconditionally segments of created IDocs which must be excluded from the transfer (transaction BD56).
