• What is the cause and solution for SAP error message /SAPAPO/SNP071 - Scheduling problem: Calendar: &1, start date: &2, end date: &3 ?

  The SAP error message /SAPAPO/SNP071 indicates a scheduling problem related to the calendar settings in the Advanced Planning and Optimization (APO) module, specifically in the Supply Network Planning (SNP) area. This error typically arises when there are issues with the defined calendar for the planning period, such as non-working days or incorrect date ranges.
  Cause:
  
  Calendar Configuration: The calendar defined for the planning area may not align with the dates specified in the planning run. This can happen if the calendar does not include the specified start and end dates or if there are non-working days that affect scheduling.
  Date Range Issues: The start and end dates provided for the planning run may fall outside the valid range defined in the calendar.
  Resource Availability: If resources or production capacities are not available during the specified dates, it can lead to scheduling issues.
  Master Data Issues: Incorrect or incomplete master data (like production versions, resources, or transportation lanes) can also lead to scheduling problems.
  
  Solution:
  
  
  Check Calendar Settings:
  
  Go to the calendar settings in the APO system and verify that the calendar includes the specified start and end dates.
  Ensure that the calendar is correctly configured to account for working and non-working days.
  
  
  
  Adjust Date Ranges:
  
  Review the start and end dates used in the planning run. Make sure they fall within the valid range of the calendar.
  If necessary, adjust the planning run dates to align with the calendar.
  
  
  
  Review Resource Availability:
  
  Check the availability of resources during the specified dates. Ensure that there are no constraints that would prevent scheduling.
  If resources are not available, consider rescheduling or adjusting the planning parameters.
  
  
  
  Validate Master Data:
  
  Ensure that all relevant master data is complete and accurate. This includes checking production versions, resources, and any other relevant data that could impact scheduling.
  
  
  
  Run Planning with Different Parameters:
  
  If the issue persists, try running the planning process with different parameters or settings to see if the error can be bypassed.
  
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like /SAPAPO/MC62 (to check the calendar) or /SAPAPO/SNP1 (to run the SNP planning) to investigate and resolve the issue.
  SAP Notes: Check for any relevant SAP Notes that may address known issues or provide additional guidance on resolving this error.
  Documentation: Refer to SAP documentation for detailed information on calendar settings and planning runs in APO.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to resolve it.
