Using this information, the process components interaction model describes the message exchange between two process components in detail.

Prerequisites

You typically model the interaction between two process components once you have answered the following:

  • Which data does a process component contain and which operations can you use to access it? Ideally you have already modeled this information in the process components model.

    Note Note

    Also when you are dealing with a partner process component (the internal structure of which you cannot know), you still need at least the service interfaces and operations with which your process components service interfaces and operations are meant to interact.

    End of the note.

  • Which process components interact with each other during a business process? Ideally you have already modeled this information in the integration scenario model.

It is only possible to model the message exchange for enterprise service interaction-type interactions.

Procedure

  1. Create a process components interactions model in the ES Repository. You have the following options:

    • Proceed as follows if you have modeled the enterprise service interaction of both of the process components in one integration scenario model:

      1. Open the integration scenario model and switch to processing mode.

      2. Create a new process components interaction model (SAP ProComp Model) using the   New   Assignment   context menu.

      In this case the modeling environment creates the process components that are involved in this interaction directly in a new interaction model. If the process components had the names PC1 and PC2, then the name of the new interaction model is automatically PC1 # PC2.

    • Proceed as follows if you have not modeled the enterprise service interaction of both of the process components in one integration scenario model:

      1. In the modeling environment create a process components interaction model type model (SAP ProComp interaction model). The name of the interaction model should be made up of the process components involved as shown below:

        <Name of the Source Process Component> – <Name of the Target Process Component>

      2. Add the process components involved in the interaction.

  2. Add the business objects, service interfaces and operations to the process components that are relevant to the interaction.

  3. SAP recommends that you refer to the interface pattern that SAP uses when you model the interaction.
