BC_DATAMODEL_SERVICE656 - Details

• The SAP error message BC_DATAMODEL_SERVICE656 indicates that a specific operation or report cannot be executed in the background because it is designed to only allow an overview list when run in that mode. This typically occurs when a report or transaction is expected to generate an interactive output, which is not compatible with background processing.
  
  Cause:
  
  Report Type: The report or transaction you are trying to execute in the background is designed to produce an interactive output, such as a detailed list or a graphical representation, which cannot be displayed in the background.
  Selection Criteria: The selection criteria or parameters you are using may not be suitable for background processing.
  Program Logic: The underlying ABAP program may have logic that restricts certain outputs to interactive mode only.
  
  
  Solution:
  
  Run in Dialog Mode: Instead of executing the report in the background, run it in dialog mode (interactive mode). This allows the report to generate the detailed output
