• What is the cause and solution for SAP error message PPDS_PB026 - Heuristic '&1' executed without result ?

  The SAP error message PPDS_PB026 indicates that a specific heuristic (denoted by &1) in the Production Planning and Detailed Scheduling (PP/DS) module was executed but did not yield any results. This can occur for various reasons, and understanding the cause is essential for troubleshooting and resolving the issue.
  Possible Causes
  
  
  No Valid Data: The heuristic may not have any valid data to process. This could be due to:
  
  No planned orders or production orders available for the heuristic to work on.
  The selection criteria defined for the heuristic do not match any existing data.
  
  
  
  Heuristic Configuration: The heuristic may not be configured correctly. This includes:
  
  Incorrect parameters or settings in the heuristic profile.
  Missing or incorrect master data (e.g., resources, products, or production versions).
  
  
  
  Resource Availability: The resources required for the heuristic to execute may not be available. This could be due to:
  
  Resource capacity constraints.
  Maintenance or downtime of resources.
  
  
  
  Planning Horizon: The planning horizon set for the heuristic may not include any relevant time periods. If the heuristic is set to plan only for a specific timeframe, and there are no orders or requirements in that timeframe, it will not produce results.
  
  
  Locking Issues: There may be locking issues in the system that prevent the heuristic from accessing the necessary data.
  
  
  Solutions
  
  
  Check Data Availability: Ensure that there are planned orders or production orders available for the heuristic to process. Review the selection criteria and adjust them if necessary.
  
  
  Review Heuristic Configuration: 
  
  Check the settings of the heuristic profile to ensure they are correct.
  Verify that all necessary master data is available and correctly configured.
  
  
  
  Resource Check: Ensure that the resources required for the heuristic are available and not blocked by maintenance or other constraints.
  
  
  Adjust Planning Horizon: Review the planning horizon settings and ensure they encompass the relevant time periods for the orders you expect to be processed.
  
  
  Check for Locks: Investigate if there are any locks on the data that might prevent the heuristic from executing properly. You can use transaction codes like SM12 to check for locks.
  
  
  Run Heuristic in Test Mode: If possible, run the heuristic in a test mode or with a smaller dataset to see if it produces results. This can help isolate the issue.
  
  
  Related Information
  
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as:
  
  /SAPAPO/HEUR for heuristic execution.
  /SAPAPO/MC90 for monitoring the execution of heuristics.
  
  
  
  SAP Notes: Check for any relevant SAP Notes that might address known issues with specific heuristics or provide updates.
  
  
  Documentation: Review the SAP documentation for the specific heuristic you are using to understand its requirements and configuration options.
  
  
  Support: If the issue persists after checking the above points, consider reaching out to SAP support for further assistance, providing them with detailed information about the heuristic and the context in which the error occurs.
  
  
  By systematically addressing these areas, you should be able to identify the cause of the PPDS_PB026 error and implement an appropriate solution.
