Asynchronous Inbound Integration Processing The following framework activities identify the object structures that are associated with the message: 1 The integration framework retrieves the record from the inbound queue. 2 The integration framework identifies the enterprise service from the retrieved record. 3 The enterprise service definition lists the object structures that the processing service uses. 4 The integration framework creates one copy of the enterprise service message for every object structure that is associated with the enterprise service. The processing sequence that is associated with the object structure specifies the sequence in which the subsequent object structure processing is to be performed on the enterprise service. The integration framework inbound integration can process numbers in either standard or scientific notation. TIP To see the processing sequence of multiple object structures associated with an enterprise service, look in the Add/Modify Additional Object Structures dialog box in the Enterprise Services application. Look for the processing order field on the Object Structure Sub-Records table window. The Enterprise Service main object structure is always processed after all the additional object structures. If the integration framework creates copies of the enterprise service message, the remaining inbound processing actions apply to each copy of the enterprise service. Output The output of this activity is one copy of the enterprise service message per object structure. User Exit Preprocessing Summary If you specify custom processing logic in the user exit class, the integration framework applies custom processing logic to the enterprise service. You can use a preprocessing method to manipulate the enterprise service before any predefined processing takes place. The predefined services do not provide any user exit classes. TIP To see if preprocessing customization exists, go to the Enterprise Service tab in the Enterprise Services application. If the Enterprise Service Configuration and Enterprise Service Response Configuration table windows show user exit classes, check each class file for a preprocessing method value. The same processing class contains the user exit preprocessing, user exit postprocessing, and user exit object processing methods. Inbound Integration Processing 25
