• What is the cause and solution for SAP error message LTR2_ES121 - &3 (&4) not unique: more fields with domain &2 found for param &1 ?

  The SAP error message LTR2_ES121 indicates that there is a uniqueness issue with the fields defined in a parameter. Specifically, the message states that there are multiple fields associated with a domain that are not unique for the specified parameter. This can occur in various contexts, such as when defining parameters in a function module, report, or other ABAP programs.
  Cause:
  The error typically arises due to the following reasons:
  
  Non-Unique Domain Fields: The domain specified in the error message has multiple fields associated with it, and the system cannot determine which field to use for the parameter.
  Incorrect Parameter Definition: The parameter may have been defined incorrectly, leading to ambiguity in the field selection.
  Data Dictionary Issues: There may be issues in the data dictionary where multiple fields share the same domain, causing conflicts.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Domain and Fields:
  
  Go to the Data Dictionary (transaction SE11) and check the domain mentioned in the error message.
  Identify all the fields that are associated with this domain and ensure that they are intended to be used in the context of the parameter.
  
  
  
  Modify Parameter Definition:
  
  If you are defining a parameter in a function module or report, ensure that you specify the field explicitly if there are multiple fields with the same domain.
  You may need to change the parameter type or specify the field name directly to avoid ambiguity.
  
  
  
  Review Related Data Elements:
  
  Check the data elements associated with the domain. If multiple data elements are using the same domain, consider whether this is necessary or if it can be simplified.
  
  
  
  Consult Documentation:
  
  Review any relevant documentation or SAP notes related to the error message for additional context or specific recommendations.
  
  
  
  Testing:
  
  After making changes, test the program or function module to ensure that the error is resolved and that the intended functionality is preserved.
  
  
  
  Related Information:
  
  Transaction Codes: SE11 (Data Dictionary), SE37 (Function Module), SE80 (Object Navigator).
  SAP Notes: Check for any SAP Notes that may address this specific error or provide additional guidance.
  Debugging: If the issue persists, consider using the debugger to trace the execution and identify where the ambiguity arises.
  
  By following these steps, you should be able to resolve the LTR2_ES121 error and ensure that your parameters are defined correctly without ambiguity.
