• What is the cause and solution for SAP error message /SAPAPO/PP_OPTIMIZER236 - Duration of PPM/PDS &1 is too long ?

  The SAP error message /SAPAPO/PP_OPTIMIZER236 indicates that the duration of a Production Planning Model (PPM) or a Production Data Structure (PDS) is too long for the optimizer to handle effectively. This can occur in the context of Advanced Planning and Optimization (APO) when the planning horizon or the duration of the production process exceeds the limits set in the system.
  Cause:
  
  Long Duration of PPM/PDS: The primary cause of this error is that the duration defined for the PPM or PDS exceeds the maximum allowable duration for the optimizer to process.
  Configuration Settings: The settings in the optimizer configuration may not be suitable for the duration of the production process.
  Data Issues: There may be incorrect or unrealistic data in the PPM or PDS that leads to an excessively long duration.
  
  Solution:
  
  
  Review and Adjust PPM/PDS Duration:
  
  Check the duration settings in the PPM or PDS. If the duration is indeed too long, consider breaking it down into smaller, more manageable segments.
  Adjust the production process to ensure that the duration is within acceptable limits.
  
  
  
  Optimizer Configuration:
  
  Review the configuration settings for the optimizer. Ensure that the settings are appropriate for the production processes you are trying to optimize.
  You may need to consult with your SAP Basis or APO consultant to adjust these settings.
  
  
  
  Data Validation:
  
  Validate the data in the PPM/PDS to ensure that there are no errors or unrealistic values that could be causing the long duration.
  Check for any dependencies or constraints that may be affecting the duration.
  
  
  
  Use of Alternative Planning Strategies:
  
  If the duration cannot be reduced, consider using alternative planning strategies or methods that can handle longer durations.
  
  
  
  Consult SAP Documentation:
  
  Refer to the SAP Help Portal or relevant documentation for specific guidelines on the limits and configurations for the optimizer.
