• What is the cause and solution for SAP error message PPEACT855 - CTM planning disallows &1 at &2 as only allowed at last activity ?

  The SAP error message PPEACT855 indicates that there is an issue with the scheduling of activities in the Capacity Planning or Production Planning module, specifically when using the Capacity Planning Tool (CTM - Capable to Match). The error message states that a certain activity is disallowed at a specific point in the planning process because it is only allowed at the last activity.
  Cause:
  This error typically arises due to the following reasons:
  
  
  Activity Constraints: The activity you are trying to schedule is restricted to be executed only at the last operation in a routing or production order. This could be due to the nature of the activity, which may require that all preceding operations be completed before it can start.
  
  
  Routing Configuration: The routing for the production order may not be set up correctly, leading to conflicts in the scheduling of activities.
  
  
  CTM Settings: The settings in the CTM configuration may not allow for the specific activity to be scheduled at the point you are trying to schedule it.
  
  
  Order Status: The status of the production order or the activities within it may not allow for the scheduling of the activity at the specified time.
  
  
  Solution:
  To resolve the PPEACT855 error, you can take the following steps:
  
  
  Check Activity Configuration: Review the configuration of the activity in the routing. Ensure that it is correctly defined to be allowed only at the last operation.
  
  
  Review Routing: Verify the routing for the production order. Make sure that the sequence of operations is correct and that the activity in question is indeed the last one.
  
  
  Adjust CTM Settings: If necessary, adjust the CTM settings to allow for the scheduling of the activity at the desired point. This may involve changing the planning parameters or constraints.
  
  
  Order Status Check: Ensure that the production order is in a status that allows for the scheduling of the activity. If the order is in a locked or completed status, you may need to change it.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific details on the activity and its constraints.
  
  
  Testing: After making changes, test the scheduling again to ensure that the error does not reoccur.
