- No root predecessors found because messages might form a cycle. ?The SAP error message /AIF/SERIALIZATION028 indicates that the Advanced Integration Framework (AIF) has detected a potential cycle in message processing. This typically occurs when the system is unable to determine a valid sequence of message processing due to circular dependencies among messages. Here’s a breakdown of the cause, potential solutions, and related information: Cause Circular Dependencies: The most common cause of this error is that the messages being processed have dependencies that form a cycle. For example, if Message A depends on Message B, and Message B depends on Message A, the system cannot determine which message should be processed first. Incorrect Configuration: Misconfiguration in the message processing logic or in the AIF settings can lead to situations where the system cannot find a valid processing order. Data Issues: Sometimes, the data being processed may inadvertently create a cycle, especially if the data references other messages or entities that are interdependent.
