• What is the cause and solution for SAP error message WES_FILTER018 - No explicit filters are defined for selection ?

  SAP Error Message:
  
  WES_FILTER018 No explicit filters are defined for selection
  
  Cause:
  This error occurs in SAP when a selection or query is executed without specifying any explicit filter criteria. In other words, the system expects at least one filter condition to limit the data selection, but none was provided. This is common in scenarios where the system or application logic requires filters to avoid processing or displaying an unfiltered, potentially very large dataset.
  
  When does it typically occur?
  
  In SAP BW (Business Warehouse) during query execution or report generation.
  In Web Intelligence (WebI) reports or other BI tools connected to SAP BW.
  When using BEx queries or InfoProviders where filters are mandatory.
  In custom ABAP programs or selection screens where filter validation is enforced.
  
  
  Solution:
  
  
  Define Explicit Filters:
  
  Go back to the selection screen or query designer.
  Add at least one filter condition (e.g., date range, customer ID, material number).
  Ensure that the filter is explicit and not left blank or set to "All".
  
  
  
  Check Query or Report Design:
  
  If using BEx Query Designer, verify that the query has mandatory filters defined.
  If filters are optional, consider making them mandatory or provide default values.
  
  
  
  Adjust Program Logic:
  
  If this error arises in a custom program, add validation logic to check if filters are provided.
  Prompt the user to enter filter values before executing the selection.
  
  
  
  Default Filters:
  
  In some cases, setting default filter values can prevent this error.
  For example, defaulting to the current fiscal year or a specific region.
  
  
  
  
  Additional Information:
  
  This error is a safeguard to prevent performance issues caused by unfiltered data retrieval.
  It helps avoid long runtimes and system overload by ensuring users specify meaningful selection criteria.
  If you believe the error is incorrect (e.g., filters are defined but still getting the error), check for:
  
  Incorrect filter syntax.
  Filters applied on wrong fields.
  Authorization issues preventing filter application.
  System or transport inconsistencies.
