The Integration Object was created from the Integration Object Wizard and some modifications on the Integration Component Fields of the Attachment Integration Component have been made.
When the EAI Siebel Adapter was executed to insert the attachment the following error was raised:
No key field name present in the integration component instance(SBL-EAI-04004)
In order to avoid this issue, it is recommended that no change is made to the attachment Integraiton Component after the Integration Object is created by the Integraiton Object Wizard.
