  The SAP error message /SAPAPO/RRP_ATP152 indicates that there is an attempt to schedule operations during non-working times in the Advanced Planning and Optimization (APO) module. This typically occurs when the planning process tries to allocate resources or schedule production activities outside of the defined working hours.
  Cause:
  
  Non-Working Time Configuration: The system has been configured with specific working times for resources (e.g., machines, labor) and the operation being scheduled falls outside these defined hours.
  Resource Availability: The resource may not be available during the requested time due to maintenance, holidays, or other non-working periods.
  Planning Calendar: The planning calendar may not align with the operational calendar, leading to scheduling conflicts.
  
  Solution:
  
  
  Check Resource Working Times:
  
  Go to the resource master data and verify the working times defined for the resource in question. Ensure that the operation is scheduled within these times.
  Adjust the working times if necessary to accommodate the scheduling needs.
  
  
  
  Adjust Planning Parameters:
  
  Review the planning parameters and settings in the APO system to ensure they align with the operational requirements.

  Modify the Operation Schedule:
  
  If possible, reschedule the operation to fall within the defined working hours.
  Use the planning board or other scheduling tools to find an appropriate time slot.
  
  
  
  Review the Planning Calendar:
  
  Ensure that the planning calendar used in the APO system matches the operational calendar. If there are discrepancies, update the planning calendar accordingly.
