  The SAP error message IP631: No maintenance plan simulation possible typically occurs when you attempt to simulate a maintenance plan in the SAP system, but the system is unable to perform the simulation due to certain conditions not being met. Here are some common causes, solutions, and related information for this error:
  Causes:
  
  Missing or Incomplete Data: The maintenance plan may not have all the required data filled in, such as the maintenance items, scheduling parameters, or task lists.
  Incorrect Status: The maintenance plan might be in a status that does not allow for simulation (e.g., it may be inactive).
  No Valid Maintenance Items: The maintenance plan may not have any valid maintenance items associated with it.
  Scheduling Parameters: The scheduling parameters may not be set correctly, leading to an inability to calculate the next maintenance date.
