• What is the cause and solution for SAP error message FIN_RE_PARSER028 - Filter condition for & does not limit the cardinality to 1. ?

  The SAP error message FIN_RE_PARSER028 indicates that a filter condition applied in a report or query does not limit the result set to a single record (cardinality of 1). This typically occurs in the context of financial reporting or data extraction where a unique record is expected based on the filter criteria provided.
  Cause:
  The error is caused by one of the following reasons:
  
  Ambiguous Filter Conditions: The filter conditions applied do not uniquely identify a single record. For example, if you are filtering by a field that can have multiple values (like a customer ID that is not unique), the system will return multiple records.
  Data Model Issues: The underlying data model may not be designed to ensure uniqueness for the queried fields, leading to multiple records being returned.
  Incorrect Query Design: The query or report may be incorrectly designed, leading to a situation where the expected unique record is not being retrieved.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Filter Conditions: Check the filter conditions you have applied. Ensure that they are specific enough to return a single record. You may need to add additional criteria to narrow down the results.
  
  
  Check Data Uniqueness: Verify that the data in the relevant fields is unique. If the data model allows for multiple entries, consider whether you need to adjust your query or the underlying data structure.
  
  
  Modify the Query: If you are using a query or report tool, modify the query to ensure that it retrieves a unique record. This may involve using aggregate functions or additional joins to limit the result set.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on the report or query you are working with. There may be best practices or examples that can help you structure your query correctly.
  
  
  Testing: After making changes, test the query or report to ensure that it now returns a single record as expected.
