• What is the cause and solution for SAP error message PK518 - Function only allowed for classic or signal-driven control cycles ?

  The SAP error message PK518 ("Function only allowed for classic or signal-driven control cycles") typically occurs in the context of Production Planning (PP) or Advanced Planning and Optimization (APO) when you are trying to execute a function that is not compatible with the type of control cycle you are using.
  
  Cause:
  The error is triggered when you attempt to perform an operation that is only applicable to classic or signal-driven control cycles, but your current configuration is set to a different type of control cycle (e.g., heuristic or optimization-based control cycles). This can happen in scenarios such as:
  
  Trying to execute a planning function that is not supported by the current control cycle.
  The control cycle is set up incorrectly or is not aligned with the planning strategy you are trying to implement.
  
  
  Solution:
  To resolve the PK518 error, you can take the following steps:
  
  
  Check Control Cycle Type: Verify the type of control cycle you are
