• What is the cause and solution for SAP error message CY687 - Requirements grouping empty. ?

  The SAP error message CY687: Requirements grouping empty typically occurs in the context of production planning and control, particularly when dealing with requirements planning and the configuration of planning strategies. This error indicates that the system is unable to find any requirements grouping for the specified material or planning scenario.
  Causes:
  
  Missing Requirements Grouping: The requirements grouping may not be defined for the material in question. This can happen if the material master data is incomplete or incorrectly configured.
  Incorrect Configuration: The configuration settings for the planning strategy or the requirements grouping may not be set up correctly in the system.
  Material Master Data Issues: The material master may not have the necessary data filled in, such as the planning view or the requirements grouping field.
  Planning Area Issues: The planning area may not be correctly defined or may not include the necessary requirements grouping.
  
  Solutions:
  
  
  Check Material Master Data:
  
  Go to the material master (transaction code MM03) and check the relevant views (especially the MRP view) to ensure that the requirements grouping is defined.
  If it is missing, you may need to update the material master with the correct requirements grouping.
  
  
  
  Review Planning Strategy:
  
  Check the planning strategy assigned to the material. Ensure that it is compatible with the requirements grouping you are trying to use.

  Define Requirements Grouping:
