• What is the cause and solution for SAP error message /SAPAPO/SEQ312 - Algorithm cannot be started as an order occurs in the past ?

  The SAP error message /SAPAPO/SEQ312 indicates that an algorithm cannot be started because there is an order that occurs in the past. This typically happens in the context of Advanced Planning and Optimization (APO) when the system is trying to process planning data that includes orders or activities with dates that are earlier than the current date.
  Cause:
  
  Past Orders: The error is primarily caused by the presence of orders (such as production orders, purchase orders, or sales orders) that have start or finish dates in the past. The planning algorithm cannot process these orders because they are not relevant for future planning.
  Incorrect Date Settings: There may be incorrect settings in the planning horizon or the date settings in the system that allow past orders to be considered.
  Data Integrity Issues: There could be data integrity issues where the order dates have not been updated correctly, leading to inconsistencies in the planning data.
  
  Solution:
  
  Review Orders: Check the orders in the system to identify any that have dates in the past. You can do this by using transaction codes like CO03 for production orders or VA03 for sales orders.
  Update or Delete Past Orders: If the past orders are no longer relevant, consider updating their dates to the current date or deleting them if they are not needed.
  Adjust Planning Horizon: Ensure that the planning horizon is set correctly in the APO system. You can adjust the planning horizon settings in the configuration to avoid including past orders in future planning runs.
  Check for Data Consistency: Run consistency checks in the system to ensure that all relevant data is accurate and up to date. This may involve checking for any inconsistencies in master data or transactional data.
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of APO you are using for any additional troubleshooting steps or known issues.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /SAPAPO/SDP94 for planning board, /SAPAPO/OM17 for order management, and others that may help in analyzing the orders.
  SAP Notes: Check SAP Notes for any updates or patches that may address this specific error or provide additional guidance.
  User Forums: Engage with SAP community forums or user groups where similar issues may have been discussed, and solutions shared.
  
  By following these steps, you should be able to resolve the /SAPAPO/SEQ312 error and ensure that your planning algorithms can run successfully.
