SAP S/4HANA Error 475: Duplicate Adapter Name
Description
Error 475 indicates that the system detected an attempt to use an adapter name that is already assigned to an existing adapter within SAP S/4HANA. This typically occurs during configuration or setup processes when defining new data integration points or during system updates.
Error Message
ERR_SQL_EXST_ADAPTER Cannot use duplicate adapter name
Known Causes
3 known causesManual Configuration Error
A user attempted to create or configure a new adapter and inadvertently provided a name that is already in use by an existing adapter.
Automated Deployment Conflict
An automated script, template, or deployment process tried to provision an adapter with a name that already exists in the target SAP S/4HANA environment.
System Migration/Import Issue
During a system migration, upgrade, or data import, adapter definitions were duplicated from a source system, leading to naming conflicts.
Solutions
3 solutions available1. Identify and Rename Duplicate Adapter Configuration medium
Locate the duplicate adapter name in the system and rename one of them to resolve the conflict.
1
Access the SAP S/4HANA system's configuration tools. This typically involves navigating to transaction `SPRO` (SAP Reference IMG).
2
Search for configurations related to adapters or integration scenarios. The exact path can vary depending on the specific integration technology being used (e.g., SAP Cloud Integration, SAP Process Orchestration, ABAP proxies). Common areas include 'SAP NetWeaver' -> 'Application Server' -> 'ABAP Connectors' or specific integration solution configuration nodes.
3
Within the adapter configuration, look for a list of defined adapters. Identify the adapter name that is being reported as duplicated.
4
Once the duplicate is found, select one of the entries and use the 'Change' or 'Edit' functionality to rename it. Choose a unique and descriptive name that adheres to any naming conventions in your organization.
5
Save the changes and restart any affected services or applications that utilize this adapter. This might include restarting the SAP S/4HANA application server or specific integration runtime components.
2. Review Integration Configuration in SAP Cloud Integration or Process Orchestration medium
Check the integration flow or interface definitions in your central integration platform for duplicate adapter configurations.
1
Log in to your SAP Cloud Integration (CPI) tenant or SAP Process Orchestration (PO) system.
2
Navigate to the relevant integration package or scenario where the adapter is configured.
3
Examine the integration flows, adapters, and their configurations. Look for any instances where the same adapter name is being used for different purposes or in redundant configurations.
4
If a duplicate adapter name is found, either modify the configuration to use a unique name or remove the redundant adapter configuration. Ensure that the remaining configuration correctly points to the intended endpoint and uses the appropriate adapter type.
5
Deploy the updated integration artifact. This will propagate the changes to the SAP S/4HANA system. Monitor the deployment status and check for any errors.
3. Check ABAP Proxy Configuration for Duplicate Sender/Receiver Names medium
Verify the configuration of ABAP proxies in S/4HANA, specifically looking for duplicate sender or receiver names that might be interpreted as adapter names.
1
Access the ABAP system where the S/4HANA is running.
2
Execute transaction `SOAMANAGER` to manage Web service configurations.
3
Navigate to 'Service Administration' -> 'Service Consumer' or 'Service Provider' depending on whether the error occurs during outbound or inbound communication.
4
Review the list of configured service consumers or providers. Pay close attention to the 'Endpoint Name' or 'Logical Name' fields. These names are often used to identify the connection and can be the source of the 'duplicate adapter name' error if they are not unique.
5
If a duplicate name is identified, rename one of the entries to ensure uniqueness. Ensure that the corresponding configuration in the target system (if it's a receiver) or the calling application (if it's a sender) is updated accordingly.
6
Save the changes and clear the relevant caches if necessary (e.g., using transaction `SMICM` or `SM53` for ICM/HTTP cache). Test the integration scenario again.
