SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_IUUC_REPL_UI - IUUC replication messages related to UI

• Message number: 015

• Message text: A maximum of &1 configurations are permitted for a single source system

Diagnosis

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

The source system is being used by multiple configurations in a 1:N
replication scenario. For performance reasons, a maximum of &V1&
configurations are permitted for a single source system. You therefore
cannot add another configuation.
Additional Information
When you create a configuration, you can decide whether you want a 1:1
replication scenario, or a 1:N replication scenario. The option
<ZK>Allow Multiple Usage</> indicates that the scenario is a 1:N
replication scenario. If you do not choose this option, then the
scenario is a 1:1 replication scenario. That is, only one configuration
can use the source system specified in the configuration.

• What is the cause and solution for SAP error message CNV_IUUC_REPL_UI015 - A maximum of &1 configurations are permitted for a single source system ?

  The SAP error message CNV_IUUC_REPL_UI015 indicates that there is a limitation on the number of configurations allowed for a single source system in the context of SAP Landscape Transformation (SLT) replication. This error typically arises when you attempt to create or manage configurations that exceed the predefined limit set by the system.
  Cause:
  The error is triggered when the number of configurations for a single source system exceeds the maximum allowed limit. This limit is defined in the system settings and is intended to prevent performance issues and ensure efficient management of configurations.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Existing Configurations: Check the existing configurations for the source system. You can do this by navigating to the SLT configuration interface and listing all configurations associated with the source system.
  
  
  Delete Unused Configurations: If there are configurations that are no longer needed or are obsolete, consider deleting them to free up space for new configurations. Ensure that you have backups or that the configurations are indeed no longer required before deletion.
  
  
  Consolidate Configurations: If possible, consolidate multiple configurations into fewer ones. This may involve merging data flows or adjusting the replication settings to reduce the number of configurations.
  
  
  Increase Configuration Limit: If your business requirements necessitate more configurations than the current limit allows, you may need to consult with your SAP Basis or system administrator to see if the limit can be increased. This may involve adjusting system parameters or settings.
  
  
  Consult Documentation: Refer to the SAP documentation or notes related to SLT and the specific error message for any additional guidance or recommendations.
