• What is the cause and solution for SAP error message DT187 - More than one field was selected as language field: & ?

  The SAP error message DT187, which states "More than one field was selected as language field: &," typically occurs in the context of data dictionary objects, such as tables or structures, where multiple fields have been incorrectly designated as language fields. In SAP, a language field is used to store language-dependent data, and only one field should be designated as such in a given context.
  Cause:
  The error arises when:
  
  More than one field in a table or structure is marked as a language field.
  The system is unable to determine which field should be used for language-specific data, leading to ambiguity.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify the Table/Structure: Determine which table or structure is causing the error. This can usually be found in the error message details.
  
  
  Check Field Definitions:
  
  Go to the Data Dictionary (transaction SE11).
  Open the relevant table or structure.
  Review the field definitions to identify which fields are marked as language fields.
  
  
  
  Modify Field Attributes:
  
  Ensure that only one field is designated as a language field. Typically, this is done by setting the "Language" attribute for the appropriate field.
  If multiple fields are marked as language fields, you will need to change the attributes of the unnecessary fields to remove the language designation.
  
  
  
  Activate Changes: After making the necessary changes, activate the table or structure to apply the modifications.
  
  
  Test: After activation, test the functionality to ensure that the error no longer occurs.
  
  
  Related Information:
