• What is the cause and solution for SAP error message SPRX340 - namespace &1 is not assigned to MDR-> creation as MDR proxy not possible ?

  The SAP error message SPRX340 indicates that a specific namespace is not assigned to the Multi-Domain Replication (MDR) system, which prevents the creation of an MDR proxy. This error typically arises in the context of SAP Master Data Governance (MDG) or when working with SAP's data replication technologies.
  Cause:
  The error occurs when:
  
  The specified namespace (indicated by &1 in the error message) is not properly configured or assigned in the system.
  The system is unable to create a proxy for the MDR due to missing or incorrect settings related to the namespace.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Namespace Assignment:
  
  Go to the transaction code SPRO to access the SAP Reference IMG.

  Check Authorization:
