  The SAP error message /SCMB/LSO620 Planning not possible; no demand passed to the optimizer typically occurs in the context of SAP Advanced Planning and Optimization (APO) or Supply Chain Management (SCM) when the optimizer is unable to find any demand data to process. This can happen for several reasons, and understanding the cause is essential for resolving the issue.
  Causes:
  
  
  No Demand Data: There may be no demand data available for the planning period you are trying to optimize. This could be due to a lack of sales orders, forecasts, or other demand sources.
  
  
  Incorrect Planning Version: The planning version you are using may not have any demand data associated with it. Ensure that you are working with the correct version.
  
  
  Selection Criteria: The selection criteria set for the planning run may be too restrictive, resulting in no demand being selected for optimization.
  
  
  Data Filters: Filters applied in the planning run (such as location, product, or time period) may exclude all demand data.
  
  
  Master Data Issues: There may be issues with master data, such as missing or incorrect product or location data, which can prevent demand from being recognized.
  
  
  Solutions:
  
  
  Check Demand Data: Verify that there is demand data available for the planning period. You can check sales orders, forecasts, and other demand sources in the relevant transactions.

  Adjust Selection Criteria: Review and adjust the selection criteria for the planning run to ensure that it is not too restrictive. Make sure that the criteria include the relevant products, locations, and time periods.
  
  
  Remove Filters: Temporarily remove any filters applied to the planning run to see if demand data is being excluded.
  
  
  Check Master Data: Review the master data for products and locations to ensure that they are correctly set up and that there are no missing or incorrect entries.
  
  
  Run Demand Planning: If you are using a demand planning module, ensure that the demand planning process has been executed successfully and that demand data is available for the optimizer.
