ILM_STOR840 - Details

• The SAP error message ILM_STOR840 indicates that a SELECT statement in the context of Information Lifecycle Management (ILM) is returning multiple results when only a single entry is expected. This typically occurs in scenarios where the system is trying to retrieve a unique record from a database table, but the query is returning more than one record.
  Cause
  The primary causes of this error can include:
  
  
  Data Integrity Issues: There may be duplicate entries in the database table that the SELECT statement is querying. This can happen due to improper data management or lack of constraints that enforce uniqueness.
  
  
  Incorrect Query Logic: The SQL query may not be correctly formulated to ensure it retrieves a unique record. For example, if the WHERE clause is not specific enough, it may match multiple records.
  
  
  
  Configuration Issues: In some cases, the configuration of the ILM settings or the underlying data model may not align with the expected data
