  The SAP error message RESCSU028, which states "Vacancy percentage is not allowed to be more than 100 percent," typically occurs in the context of resource management or capacity planning within SAP systems, particularly in modules related to project management or resource allocation.
  Cause:
  This error arises when the system detects that the vacancy percentage for a resource (such as a position, employee, or project) exceeds 100%. The vacancy percentage is calculated based on the available capacity versus the total capacity. A value greater than 100% indicates that the system is trying to allocate more resources than are available, which is not feasible.

  Configuration Issues: Misconfiguration in the resource management settings or parameters.
  Calculation Errors: Errors in the underlying calculations that determine the vacancy percentage.

  Adjust Resource Allocation: If the vacancy percentage is calculated based on resource allocation, review the allocations to ensure they are within the available capacity.
  
  
  Correct Calculation Logic: If there are custom calculations or logic implemented, verify that they are functioning correctly and not leading to inflated vacancy percentages.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on managing vacancy percentages and resource allocation.
