Mapping Relations with Interface Splitting 

In certain instances it may be necessary to assign multiple inbound interfaces on the receiver side when defining a mapping relation.

Example: A very large IDoc interface is being used on the outbound side at the sender. However, on the inbound side at the receiver, only small IDoc interfaces are available for processing the message. In this case, the message must be divided up and sent to multiple inbound interfaces.

You have the option here of formulating conditions for the distribution of the message to the various receiver interfaces.

An interface splitting of this type is indicated in the Display/Change Mapping Relation editor by multiple table lines. An additional Conditions column is shown in the table that displays the conditions for forwarding the message to the corresponding interface. In change mode you can choose the search help icon () to call the conditions editor.

You have the following functions in the Display/Change Mapping Relation editor to help you here:
