• What is the cause and solution for SAP error message LTR2_KB_GUI163 - Selected Logical Field is already a Proxy ?

  The SAP error message LTR2_KB_GUI163 indicates that the selected logical field is already a proxy. This typically occurs in the context of SAP's data modeling or data extraction processes, particularly when working with logical fields in the context of SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  The error arises when you attempt to create or modify a logical field that is already defined as a proxy in the system. A proxy in this context refers to a representation of a data source or a logical field that is already linked to a specific data model or extraction process. This can happen due to:
  
  Duplicate Definitions: You may be trying to define a logical field that has already been defined elsewhere in the system.
  Incorrect Configuration: The configuration settings may not be correctly set up, leading to conflicts in logical field definitions.
  System State: The system may be in a state where it does not recognize the current configuration due to caching or other issues.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Definitions: Verify if the logical field you are trying to create or modify already exists as a proxy. You can do this by navigating to the relevant data model or extraction settings in SAP BW or HANA.
  
  
  Modify Existing Proxy: If the logical field is already defined, consider modifying the existing proxy instead of creating a new one. This may involve changing its properties or usage in the data model.
  
  
  Clear Cache: Sometimes, clearing the cache in the SAP system can resolve issues related to stale configurations. You can do this by using transaction codes like RSADMIN or RSRT to refresh the data model.
  
  
  Consult Documentation: Review the SAP documentation related to logical fields and proxies to ensure that you are following the correct procedures for defining and using them.
  
  
  Seek Help from SAP Support: If the issue persists, consider reaching out to SAP support for assistance. They can provide more specific guidance based on your system configuration and the context of the error.
  
  
  Related Information:
  
  SAP BW Documentation: Look for documentation on logical fields and proxies in SAP BW to understand their roles and how to manage them effectively.
  SAP Community: Engage with the SAP Community forums where other users may have encountered similar issues and can share their solutions.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1 (Data Warehousing Workbench) and RSD1 (InfoObject Maintenance) for managing data models and logical fields.
  
  By following these steps, you should be able to identify the cause of the error and implement a suitable solution.
