• What is the cause and solution for SAP error message SADL_GW_DT_SB_UI014 - Navigation properties '&1' and '&2' differ only in upper and lower case ?

  The SAP error message SADL_GW_DT_SB_UI014 indicates that there is a conflict in the navigation properties of your data model, specifically that two navigation properties differ only in case sensitivity. This can lead to ambiguity in how the properties are referenced, especially in systems that are case-sensitive.
  Cause:
  The error typically arises when:
  
  Two navigation properties are defined in a way that they have the same name but differ only in their case (e.g., PropertyA and propertya).
  This can happen due to naming conventions or inconsistencies in the data model or service definitions.
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Identify the Properties: Check the data model or service definition to identify the navigation properties that are causing the conflict. The error message will indicate which properties are in conflict (represented as &1 and &2).
  
  
  Rename Properties: Modify the names of the conflicting properties to ensure they are unique. This may involve:
  
  Changing the case of one of the properties.
  Renaming one of the properties entirely to a different name that does not conflict.
  
  
  
  Update References: After renaming, ensure that all references to the renamed properties in your code, configuration, or UI are updated accordingly.
  
  
  Regenerate Artifacts: If you are using generated artifacts (like OData services), you may need to regenerate them to reflect the changes made in the data model.
  
  
  Test the Changes: After making the changes, test the application to ensure that the error is resolved and that the functionality is working as expected.
  
  
  Related Information:
  
  Case Sensitivity: Be aware of the case sensitivity rules in the programming language or framework you are using. Some systems treat identifiers as case-sensitive, while others do not.
  Naming Conventions: Establish and follow consistent naming conventions for properties in your data models to avoid similar issues in the future.
  Documentation: Refer to SAP documentation for guidelines on naming conventions and best practices for defining navigation properties in your data models.
  
  By following these steps, you should be able to resolve the SADL_GW_DT_SB_UI014 error and prevent similar issues in the future.
