This error indicates that a certain operation or function expects exactly one instance of a particular object or entity, but it has found either none or more than one.
  Cause:
  
  Multiple Instances: The most common cause of this error is that the operation is trying to retrieve or manipulate a business object that is expected to be unique (e.g., a specific record in a database), but the query or selection criteria have returned multiple records or none at all.
  Incorrect Key: The key used to identify the business object might not be unique, leading to multiple records being returned.
  Data Integrity Issues: There may be data integrity issues in the underlying database, such as duplicate entries that violate the expected uniqueness of the business object.
  
  Solution:
  
  Check Selection Criteria: Review the selection criteria used in the operation to ensure that it is correctly defined to return a single instance. Make sure that the key fields are specified correctly.

  Debugging: If you have access to the ABAP code, you can debug the relevant method or function module to see what data is being retrieved and why it is not returning a single instance.
  Review Business Logic: Ensure that the business logic implemented in the BOPF is correct and that it adheres to the expected behavior of the business object.
  Consult Documentation: Refer to the SAP documentation for BOPF and the specific business object you are working with to understand the expected behavior and constraints.
