  SAP Error Message:
  
  WES_FILTER099 Internal error in &1
  
  Meaning / Cause
  The error message WES_FILTER099 Internal error in &1 indicates that an internal error occurred within a specific component or program/module during the execution of a filter or related processing step in SAP. The placeholder &1 is replaced at runtime by the name of the program, function module, or component where the error happened.
  This error is typically related to SAP's Workflow Engine Services (WES) or other filtering mechanisms used in workflow or data selection processes. The internal error suggests that the system encountered an unexpected condition or exception that it could not handle properly.
  Common causes include:
  
  Programming errors or bugs in the filter logic or function module.
  Incorrect or inconsistent data passed to the filter.
  Missing or incorrect configuration related to the filter or workflow.
  Authorization issues causing the filter to fail internally.
  System inconsistencies or missing objects (e.g., missing function modules, classes, or tables).
  
  
  Where It Occurs
  
  During workflow processing, especially when filters are applied to determine workflow recipients or conditions.
  In custom or standard function modules used as filters.
  When executing selection criteria or dynamic filters in reports or workflows.
  
  
  How to Analyze
  
  Check the exact text of the message in the system (transaction SE91) to confirm the message class and text.
  Identify the component or program name substituted in &1 in the error message. This tells you where the error occurred.
  Look at the short dump (ST22) if available, to get detailed technical information about the error.
  Check the application log (transaction SLG1) for related error entries.
  Review the filter logic or function module mentioned in the error for possible coding or data issues.
  Check authorizations of the user executing the workflow or filter.
  Debug the filter function module or program to find the exact point of failure.
  
  
  Possible Solutions
  
  Fix the underlying code if the error is due to a programming bug. This may require ABAP development support.
  Correct the data passed to the filter to ensure it meets expected formats and values.
  Adjust or correct configuration related to the workflow or filter.
  Ensure all required objects (function modules, classes, tables) exist and are consistent.
  Check and assign proper authorizations to the user or process executing the filter.
