  The SAP error message /SAPAPO/OM_ERROR2063 with the description "Negative real time" typically occurs in the context of SAP Advanced Planning and Optimization (APO) when there is an issue with the planning data, particularly related to time-based calculations or scheduling.
  Cause:
  
  
  Negative Time Values: This error usually indicates that there is a negative time value being processed in the system. This can happen if the planning data has inconsistencies, such as:

  Issues with the master data, such as incorrect calendar settings or time zone configurations.
  
  
  
  Data Inconsistencies: If there are discrepancies in the data being used for planning, such as missing or incorrect entries in the master data (e.g., product master, location master), it can lead to negative time calculations.
  
  
  Configuration Issues: Incorrect configuration settings in the APO system can also lead to this error, particularly in the areas of planning books, data views, or key figures.
  
  
  Solution:
  
  
  Check Master Data: Review the master data for the relevant products, locations, and resources to ensure that all time-related fields (like lead times, durations, etc.) are correctly defined and do not contain negative values.
  
  
  Review Planning Parameters: Check the planning parameters and settings in the APO system. Ensure that the time periods and calendars are correctly configured and that there are no overlaps or gaps that could lead to negative time calculations.
  
  
  Analyze Planning Books and Key Figures: Look into the planning books and key figures being used. Ensure that the key figures are correctly defined and that the calculations do not inadvertently result in negative values.
  
  
  Check for Data Consistency: Run consistency checks on the planning data to identify any discrepancies or errors that may be causing the issue. This can often be done using standard SAP transaction codes or reports designed for data consistency checks.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error. There may be patches or updates that resolve known issues related to this error message.
