• What is the cause and solution for SAP error message /UI2/CDMFCC381 - MasterLanguage not maintatained as initial key. Using Fallback &1 ?

  The SAP error message /UI2/CDMFCC381 MasterLanguage not maintained as initial key. Using Fallback &1 typically occurs in the context of SAP Fiori applications or UI5 applications when there is an issue with the language settings or the configuration of the master language for a particular application or service.
  Cause:
  
  Missing Master Language Configuration: The master language for the application or service is not set or maintained in the system. This can happen if the application is not properly configured to support multiple languages.
  Fallback Mechanism: The system is attempting to use a fallback language (indicated by &1 in the error message) because it cannot find the required translations or texts in the master language.
  Transport Issues: If the application was recently transported from one system to another, the language settings may not have been included in the transport request.
  
  Solution:
  
  
  Maintain Master Language:
  
  Go to the relevant transaction (e.g., SE80 for Object Navigator or SE11 for Data Dictionary) and check the configuration for the application or service.
  Ensure that the master language is set correctly. You can do this by navigating to the relevant settings in the application configuration.
  
  
  
  Check Language Settings:
  
  Verify that the necessary language packs are installed in your SAP system. You can check this in transaction SMLT (Language Transport).
  Ensure that the texts and translations for the master language are maintained in the relevant tables.
  
  
  
  Fallback Language Configuration:
  
  If the master language is not available, ensure that the fallback language is correctly configured. This can usually be done in the application settings or by checking the language settings in the backend.
  
  
  
  Transport Requests:
  
  If the issue arose after a transport, check the transport request to ensure that all necessary language-related objects were included.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the application to identify where the fallback is being triggered and why the master language is not being recognized.
