  The SAP error message /SAPAPO/OM_ERROR351 indicates that there is an issue with the configuration of resources in the SAP Advanced Planning and Optimization (APO) module, specifically related to Work Force Management (WFM). This error typically arises when the system expects that all modes of an activity should utilize WFM resources, but the configuration does not meet this requirement.
  Cause:
  
  Resource Configuration: The error often occurs when the resources assigned to an activity are not properly configured to be used across all modes. Each mode of an activity should have a corresponding WFM resource defined.
  Activity Modes: If an activity has multiple modes (e.g., different ways to perform the same task), and not all modes are linked to WFM resources, the system will trigger this error.
  Planning Version: The planning version being used may not have the correct settings or data for WFM resources.
  
  Solution:
  
  
  Check Resource Assignment:
  
  Go to the resource master data and ensure that all modes of the activity are assigned to WFM resources.
  Ensure that the resource types are correctly defined and that they are set up to be used in the relevant planning scenarios.
  
  
  
  Review Activity Configuration:

  If necessary, create or modify the WFM resources to ensure they are available for all modes.
  
  
  
  Update Planning Version:
  
  If you are using a specific planning version, ensure that it is correctly set up to include the necessary WFM resources.
  You may need to adjust the planning version settings to include the required resources.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources related to WFM and resource management in APO for additional guidance on configuration.
  
  
  
  Testing:
