  SAP Error Message WY161
  Message Text:
  
  The entry table that should contain the required values is empty.
  
  Cause
  This error typically occurs in SAP Workflow or related modules when a program or function module expects an internal table (entry table) to be filled with certain data, but the table is found to be empty at runtime.
  Common scenarios include:
  
  A workflow step or function module expects input data in an internal table, but the data retrieval step failed or returned no records.
  A selection or data fetch from the database did not return any entries.
  Incorrect or missing input parameters leading to no data being selected.
  Custom code or enhancements that manipulate internal tables but do not populate them correctly.
  
  
  Solution
  To resolve the WY161 error, follow these steps:
  
  
  Check the Data Source:
  
  Verify that the data source or database table from which the internal table is supposed to be filled actually contains data.
  Run the selection or query manually (e.g., via SE16/SE16N or debugging) to confirm data availability.
  
  
  
  Review Input Parameters:
  
  Ensure that the input parameters or selection criteria passed to the program/function module are correct and valid.
  Incorrect or overly restrictive filters can result in empty result sets.
  
  
  
  Debug the Program/Workflow:
  
  Use the ABAP debugger to trace the point where the internal table is supposed to be filled.
  Check why the table remains empty — is the select statement failing, or is the data being cleared inadvertently?
  
  
  
  Check Custom Code or Enhancements:
  
  If custom code or user exits/enhancements are involved, verify that they correctly populate the internal table.
  Look for any logic that might clear or skip filling the table.
  
  
  
  Adjust Workflow or Program Logic:
  
  If the empty table is a valid scenario, consider adding error handling or default values to avoid the error.
  Alternatively, modify the workflow or program to handle empty tables gracefully.
