• What is the cause and solution for SAP error message USMD2030 - Entity type &2, UI element &1: Select an attribute with data type CHAR(1) ?

  The SAP error message USMD2030 typically occurs in the context of SAP Master Data Governance (MDG) when working with UI elements in the data model. This error indicates that a specific UI element is expecting an attribute of data type CHAR(1), but the selected attribute does not meet this requirement.
  Cause:
  The error is caused by the selection of an attribute that does not have the correct data type. Specifically, the UI element is designed to work with a single-character string (CHAR(1)), but the attribute you have selected either has a different data type or is not defined as a single-character string.
  Solution:
  To resolve this error, follow these steps:
  
  
  Check the Attribute Definition:
  
  Go to the data model where the entity type and UI element are defined.
  Verify the attributes of the entity type in question. Ensure that the attribute you are trying to use is defined as CHAR(1).
  
  
  
  Select the Correct Attribute:
  
  If the attribute you selected is not of type CHAR(1), you will need to select a different attribute that meets the requirement.
  If there is no suitable attribute, consider creating a new attribute of type CHAR(1) if it makes sense for your data model.
  
  
  
  Adjust UI Element Configuration:
  
  If you are customizing the UI element, ensure that it is configured to accept the correct data type. This may involve modifying the UI configuration or the underlying data model.
  
  
  
  Test the Changes:
  
  After making the necessary adjustments, test the UI element to ensure that the error no longer occurs and that the functionality works as expected.
