• What is the cause and solution for SAP error message MW871 - Currently not possible to change alloc profile after simulating qties ?

  The SAP error message MW871, which states "Currently not possible to change allocation profile after simulating quantities," typically occurs in the context of the allocation process in SAP, particularly when dealing with stock allocation or distribution scenarios. This error indicates that the system does not allow changes to the allocation profile after a simulation of quantities has been performed.
  
  Cause:
  
  Simulation Lock: When you simulate quantities in the allocation process, the system locks certain parameters to ensure data integrity. This lock prevents changes to the allocation profile until the simulation is either completed or canceled.
  Process Flow: The allocation process may have specific steps that need to be followed in a certain order. Changing the allocation profile after a simulation can disrupt this flow.
  Configuration Settings: There may be specific configuration settings in the allocation process that restrict changes after a simulation.
  
  
  Solution:
  
  Cancel Simulation: If you need to change the allocation profile, you should first
