• What is the cause and solution for SAP error message USMD2031 - Entity type &2, UI element &1: Select an attribute with data type STRING ?

  The SAP error message USMD2031 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 STRING, but the selected attribute does not meet this requirement.
  Cause:
  The error is caused by one of the following reasons:
  
  Incorrect Attribute Selection: The UI element is configured to use an attribute that is not of the STRING data type. This could happen if the attribute is of a different data type, such as INTEGER, DECIMAL, or DATE.
  Data Model Configuration: There may be a misconfiguration in the data model where the expected data type for the UI element does not match the actual data type of the attribute.
  UI Configuration Issues: The UI configuration might be set up incorrectly, leading to the selection of an inappropriate attribute for the UI element.
  
  Solution:
  To resolve the USMD2031 error, you can follow these steps:
  
  
  Check Attribute Data Type:
  
  Go to the data model configuration in SAP MDG.
  Identify the entity type and the UI element that is causing the error.
  Verify the data type of the attribute that is currently selected for the UI element. Ensure that it is of type STRING.
  
  
  
  Select the Correct Attribute:
  
  If the selected attribute is not of type STRING, change it to an appropriate attribute that has the STRING data type.
  If necessary, create a new attribute of type STRING in the data model and use it for the UI element.
  
  
  
  Review UI Configuration:
  
  Check the UI configuration settings for the entity type and ensure that all UI elements are correctly mapped to the appropriate attributes.
  Make sure that the UI elements are configured to accept the correct data types as per the data model.
