• What is the cause and solution for SAP error message UCI2074 - Field &1 in conversion operator can only have a single value selection ?

  The SAP error message UCI2074 indicates that there is an issue with the selection criteria in a conversion operator where a field is expected to have a single value, but multiple values are being provided. This typically occurs in the context of ABAP programming or when using certain selection screens in SAP.
  Cause:
  The error arises when:
  
  A field in a conversion operator (like a SELECT statement or a data conversion function) is being supplied with multiple values instead of a single value.
  The logic in the program or the selection screen is incorrectly set up to allow multiple selections for a field that is supposed to accept only one.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Field Definition: Ensure that the field in question is defined to accept only a single value. This can be done by reviewing the data dictionary (SE11) or the relevant ABAP code.
  
  
  Modify the Selection Logic: If the field is intended to accept only a single value, ensure that the selection logic in your program or report is modified to restrict the input to a single value. This may involve:
  
  Changing the selection screen definition to use a single value input instead of a multiple selection.
  Implementing logic to handle cases where multiple values are inadvertently passed.
  
  
  
  Use Appropriate Operators: If you need to filter based on multiple values, consider using appropriate operators or structures that allow for such filtering, like using IN for a list of values, but ensure that the field itself is capable of handling it.
  
  
  Debugging: If you are unsure where the error is occurring, use debugging tools in SAP (like the ABAP debugger) to trace the execution of your program and identify where the multiple values are being passed.
  
  
  Consult Documentation: Review SAP documentation or help resources for specific details on the conversion operator you are using, as there may be additional constraints or requirements.
  
  
  Related Information:
  
  Transaction Codes: You may want to check transaction codes like SE80 (Object Navigator) or SE38 (ABAP Editor) to find and modify the relevant program.
  SAP Notes: Look for SAP Notes related to this error message for any patches or updates that may address the issue.
  Community Forums: SAP Community or other forums can be helpful to see if others have encountered and resolved similar issues.
  
  By following these steps, you should be able to identify the cause of the UCI2074 error and implement a solution to resolve it.
