• What is the cause and solution for SAP error message MDG_GN057 - More than one language field defined for table/structure &1 ?

  The SAP error message MDG_GN057 indicates that there is an issue with the configuration of a data model in SAP Master Data Governance (MDG). Specifically, it means that more than one language field has been defined for a particular table or structure, which is not allowed.
  Cause:
  The error occurs when:
  
  A data model or structure has been incorrectly configured to include multiple fields that are intended to store language-dependent data (e.g., descriptions, names) but are not properly set up to handle multiple languages.
  The system expects only one language field per table/structure for language-dependent data, and having more than one leads to ambiguity in data handling.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Data Model Configuration:
  
  Go to the data model configuration in the MDG application.
  Check the structure or table that is causing the error (indicated by &1 in the error message).
  Identify the fields that are defined as language fields.
  
  
  
  Remove or Consolidate Language Fields:
  
  If you find multiple language fields, you need to either remove the redundant fields or consolidate them into a single language field.
  Ensure that the remaining language field is correctly configured to handle language-dependent data.
  
  
  
  Check for Custom Enhancements:
  
  If there are any custom enhancements or modifications made to the standard data model, review them to ensure they do not introduce additional language fields.
  
  
  
  Test the Configuration:
  
  After making the necessary changes, test the configuration to ensure that the error no longer occurs and that the data model behaves as expected.
  
  
  
  Transport Changes:
  
  If you are working in a development environment, ensure that the changes are transported to the quality and production environments as needed.
