• What is the cause and solution for SAP error message /SAPAPO/PPM_MAINTAIN858 - Assign a maximum mode combinations number ?

  The SAP error message /SAPAPO/PPM_MAINTAIN858 typically occurs in the context of SAP Advanced Planning and Optimization (APO), particularly when working with the Production Planning and Detailed Scheduling (PP/DS) module. This error indicates that the maximum number of mode combinations for a particular resource or production process has been exceeded.
  Cause:
  The error is triggered when the system attempts to assign more mode combinations than the defined limit for a specific resource. Mode combinations are used in production planning to define different ways a resource can operate (e.g., different production modes, capacities, or constraints). Each resource has a maximum number of mode combinations that can be defined, and exceeding this limit results in the error.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Maximum Mode Combinations Setting:
  
  Go to the configuration settings for the resource in question and check the maximum number of mode combinations allowed. This can usually be found in the resource master data or in the configuration settings for the production process.
  
  
  
  Reduce Mode Combinations:
  
  Review the existing mode combinations and see if any can be removed or consolidated. This may involve analyzing the production process to determine if all defined modes are necessary.
  
  
  
  Increase Maximum Limit:
  
  If it is essential to have more mode combinations, you may need to increase the maximum limit. This can typically be done in the configuration settings of the APO system. Consult with your SAP Basis or configuration team to make this change.
  
  
  
  Review Planning Strategies:
  
  Sometimes, the planning strategy or the way modes are defined can lead to unnecessary complexity. Review the planning strategies being used and see if they can be simplified.
