metaobject (MO_Instance) and the input and output business objects as its children. The verb for the wrapper business object must be a valid operation for the specified instance.
The information about the child business object, whether it is an input or output type, is obtained from the Application Specific Information (ASI) of the wrapper business object’s attributes.
Example: ASI Type=input indicates that the child business object is of input type.
The input child business object is first converted to an XML message by the XML data handler. The business object is then transformed into a CIS record using the CIS utility. Then the operation is executed using the CIS Client API.
If the operation sends some output XML message, it is converted to an output child business object; and the output child business object in the wrapper business object is populated with the appropriate value.
Status updates
Any error conditions that occur while processing are logged as detailed error messages in the adapter log.
ReturnStatusDescriptor: The connector populates a structure called the ReturnStatusDescriptor with the message and status of the latest error that occurred during the processing of a service call request. You can access the ReturnStatusDescriptor to find the reason for the cause of a failure during a service call request. The adapter framework propagates the structure, as appropriate.
