• What is the cause and solution for SAP error message ARUN_MAIN170 - No open supply available after locking. ?

  The SAP error message ARUN_MAIN170: No open supply available after locking typically occurs in the context of the Advanced Planning and Optimization (APO) module, particularly when dealing with supply chain planning and allocation processes. This error indicates that the system is unable to find any available supply for a specific demand after certain locks have been applied.
  Causes:
  
  Locked Resources: The error may arise if the resources or stock that are needed to fulfill the demand are locked for some reason, such as being reserved for another process or transaction.
  Supply Shortage: There may simply be no available stock or supply to meet the demand due to inventory levels being too low.
  Planning Parameters: Incorrect planning parameters or settings in the APO system can lead to this error, especially if the planning horizon is not set correctly.
  Data Consistency Issues: There may be inconsistencies in the master data or transactional data that prevent the system from finding available supply.
  Time Period Issues: The demand may fall outside the planning time frame, leading to no available supply being found.
  
  Solutions:
  
  Check Locks: Investigate if there are any locks on the resources or stock. You can use transaction codes like SM12 to check for locks and release them if necessary.
  Review Inventory Levels: Check the inventory levels to ensure that there is sufficient stock available to meet the demand. If not, consider adjusting your inventory or supply planning.

  Data Consistency Check: Perform a consistency check on your master data and transactional data to ensure there are no discrepancies that could be causing the issue.
