This error typically occurs in the context of Advanced Planning and Optimization (APO) when working with production planning and scheduling.
  Cause:
  The error is caused by the following scenarios:
  
  Missing Primary Resource: The calendar resource you are trying to maintain does not have an associated primary resource defined for the specified mode. In SAP APO, a primary resource is essential for the system to understand how to utilize the calendar resource effectively.

  Navigate to the relevant resource and check the "Modes" tab to ensure that a primary resource is defined.
  
  
  
  Review Resource Modes:
  
  Ensure that the modes defined for the resource are correctly set up and that they correspond to the intended production processes.
  
  
  
  Check for Inconsistencies:
  
  Review any recent changes made to the resource or calendar settings that might have led to this issue.
  If necessary, consult with your SAP Basis or technical team to check for any inconsistencies in the system.
  
  
  
  Testing:
