• What is the cause and solution for SAP error message /SAPAPO/OM_ERROR2403 - Only WFM activities can be planned on a WFM resource ?

  The SAP error message /SAPAPO/OM_ERROR2403 indicates that there is an attempt to plan non-WFM (Workforce Management) activities on a resource that is designated as a WFM resource. This error typically arises in the context of SAP Advanced Planning and Optimization (APO) when using the Workforce Management module.
  Cause:
  
  Resource Type: The resource you are trying to plan activities for is defined as a WFM resource. WFM resources are specifically designed to handle workforce-related activities, and they cannot be used for other types of planning activities.
  Activity Type: The activity you are trying to plan is not compatible with WFM resources. For example, if you are trying to schedule production activities or maintenance tasks on a WFM resource, this will trigger the error.
  Configuration Issues: There may be configuration settings in the system that incorrectly classify a resource or activity type.
  
  Solution:
  
  Check Resource Definition: Verify the definition of the resource in the system. Ensure that it is correctly classified as a WFM resource and that it is intended for WFM activities only.
  Use Appropriate Resources: If you need to plan activities that are not WFM-related, you should use a different resource that is not classified as a WFM resource. This may involve creating a new resource or modifying an existing one.
  Review Activity Types: Ensure that the activities you are trying to plan are compatible with the resource type. If they are not, you will need to either change the activity type or select a different resource.
  Configuration Review: If you suspect that there is a configuration issue, review the settings in the SAP system related to resource and activity type definitions. Make sure that they align with your planning requirements.
  
  Related Information:
